Question 1ONTAP Cluster Fundamentals and Administration

In an ONTAP cluster, which component is responsible for hosting the SVM (vserver) definitions and cluster-wide configuration database?

  1. The management LIF on each node
  2. The cluster management switch
  3. The external SNMP trap host
  4. The replicated, cluster-wide configuration that each node holds a copy of Correct answer.

Explanation

ONTAP stores cluster configuration in a replicated database so that every node holds a consistent copy, which allows cluster-wide operations to survive a single node loss. Management LIFs and switches are access paths, not the configuration store.

Question 2ONTAP Cluster Fundamentals and Administration

A storage administrator wants a new SVM to serve NFS and CIFS data with its own namespace and its own administrative delegation. Which ONTAP object must be created to provide that isolated logical server?

  1. A new IPspace
  2. A new SVM (vserver) Correct answer.
  3. A new aggregate
  4. A new broadcast domain

Explanation

An SVM is the logical server unit in ONTAP that owns volumes, LIFs, protocols, and its own namespace, and it can be delegated to a tenant administrator. Aggregates, broadcast domains, and IPspaces are supporting infrastructure objects rather than the isolated data server itself.

Question 3ONTAP Cluster Fundamentals and Administration

Which statement accurately describes the role of a data LIF in an ONTAP cluster?

  1. It replaces the need for an SVM namespace
  2. It provides client access to data and can fail over or migrate across ports and nodes Correct answer.
  3. It is bound to a single physical port and cannot move between nodes
  4. It is used only for cluster peering traffic between sites

Explanation

A data LIF carries client protocol traffic and is designed to fail over or be migrated to another port or node, preserving client access. It is not pinned permanently to one port, nor is it a peering-only or namespace-replacing object.

Question 4ONTAP Cluster Fundamentals and Administration

What is the primary purpose of an aggregate in ONTAP?

  1. To provide a pool of physical storage from which volumes are created Correct answer.
  2. To store the cluster configuration database
  3. To route NFS requests to the correct data LIF
  4. To authenticate CIFS users against Active Directory

Explanation

An aggregate is composed of disks (or disk partitions) and presents capacity that FlexVol volumes are carved from. Routing, configuration storage, and authentication are handled by other ONTAP components.

Question 5ONTAP Cluster Fundamentals and Administration

Which ONTAP feature allows a volume to grow or shrink dynamically within the space available in its containing aggregate?

  1. FlexVol Correct answer.
  2. SnapMirror
  3. Infinite Volume
  4. FlexGroup

Explanation

FlexVol volumes are thin-provisioned and can grow or shrink within the aggregate's free space, which is a core ONTAP storage efficiency behavior. FlexGroup, Infinite Volume, and SnapMirror address scaling, large namespaces, and replication respectively.

Question 6ONTAP Cluster Fundamentals and Administration

An administrator needs to verify which nodes are members of the cluster and their health status. Which command best serves this purpose?

  1. volume show -fields size
  2. snapshot policy show
  3. system node show Correct answer.
  4. network interface show

Explanation

The system node show command lists cluster nodes with health and status details, making it the right tool for confirming membership and node state. The other commands report on volumes, LIFs, and snapshot policies rather than node membership.

Question 7ONTAP Cluster Fundamentals and Administration

Which protocol does ONTAP use for the cluster interconnect to carry private intra-cluster traffic between nodes?

  1. iSCSI over the management network
  2. The cluster interconnect using dedicated high-speed links Correct answer.
  3. NFSv4 over the data network
  4. CIFS over the client network

Explanation

ONTAP nodes communicate over a dedicated cluster interconnect network that carries private cluster traffic such as heartbeats and configuration replication. Client protocols like NFS, iSCSI, and CIFS run on data LIFs, not the interconnect.

Question 8ONTAP Cluster Fundamentals and Administration

What does an ONTAP IPspace isolate?

  1. User quotas within a volume
  2. Network address spaces and their routing, including LIFs and subnets Correct answer.
  3. Snapshot copies between volumes
  4. Disk ownership between nodes

Explanation

An IPspace is a separate network namespace that contains its own subnets, LIFs, and routing tables, which is useful for multi-tenant or overlapping-address environments. Disk ownership, snapshots, and quotas are unrelated to IPspaces.

Question 9ONTAP Cluster Fundamentals and Administration

A cluster administrator must confirm the ONTAP software version running on each node after an upgrade. Which command provides that information?

  1. volume show -instance
  2. system image show Correct answer.
  3. lun show
  4. vserver services name-service dns show

Explanation

The system image show command lists the ONTAP images installed on each node and indicates which image is currently booted. The other commands report on volumes, LUNs, and DNS configuration rather than software images.

Question 10ONTAP Cluster Fundamentals and Administration

An administrator wants a new FlexVol to be thin-provisioned so that it only consumes space as data is written. Which statement describes the default ONTAP behavior that supports this?

  1. Volumes reserve their full nominal size from the aggregate at creation
  2. Volumes automatically convert to FlexGroup when they exceed 1 TB
  3. Volumes report a nominal size but consume aggregate space only for written data Correct answer.
  4. Volumes cannot be resized after creation

Explanation

FlexVol volumes are thin-provisioned by default, so the nominal size is a logical limit while actual space is consumed as data is written. They do not pre-reserve full capacity, auto-convert to FlexGroup, or become fixed in size.

Question 11ONTAP Cluster Fundamentals and Administration

A volume must be replicated to a remote cluster for disaster recovery with periodic, schedule-based transfers. Which ONTAP technology is designed for this?

  1. SnapVault
  2. SnapMirror Correct answer.
  3. FlexCache
  4. Deduplication

Explanation

SnapMirror replicates volume data between clusters on a schedule (or on demand) to provide a remote copy for disaster recovery. SnapVault is a disk-to-disk backup relationship, FlexCache caches data, and deduplication saves space locally.

Question 12ONTAP Cluster Fundamentals and Administration

An administrator creates a new data LIF on an SVM. Which two attributes must be consistent for the LIF to function correctly? (Choose the best single answer.)

  1. The LIF's home node and the volume's owning aggregate
  2. The LIF's snapshot policy and the volume's export policy
  3. The LIF's IPspace, subnet, and SVM assignment Correct answer.
  4. The LIF's deduplication setting and the aggregate's RAID type

Explanation

A LIF must belong to an SVM and be placed in a subnet within the correct IPspace so that routing and failover work as intended. Aggregates, snapshot policies, and RAID types are unrelated to LIF network configuration.

Question 13ONTAP Cluster Fundamentals and Administration

What is the effect of creating a volume as a FlexGroup rather than a FlexVol?

  1. It spans multiple constituent volumes across nodes to scale capacity and performance Correct answer.
  2. It restricts the volume to a single node for isolation
  3. It disables snapshots for the volume
  4. It removes the need for an aggregate

Explanation

A FlexGroup is composed of multiple constituent volumes distributed across nodes, providing scale-out capacity and performance for large workloads. It still relies on aggregates and supports snapshots, and its purpose is the opposite of single-node restriction.

Question 14ONTAP Cluster Fundamentals and Administration

An SVM needs to present block storage to an ESXi host. Which ONTAP configuration is required on the SVM?

  1. A CIFS server and an Active Directory domain join
  2. An iSCSI or FC LIF and a LUN mapped to an igroup Correct answer.
  3. An NFS export policy and a junction path
  4. A snapshot policy and a quota rule

Explanation

Block access requires a SAN LIF (iSCSI or FC) plus a LUN mapped to an initiator group that contains the host initiator. CIFS, NFS exports, snapshots, and quotas serve other purposes and do not enable block presentation.

Question 15ONTAP Cluster Fundamentals and Administration

Which ONTAP object controls which client hosts are permitted to mount an NFS export on an SVM?

  1. Igroup
  2. Export policy with rules Correct answer.
  3. Snapshot policy
  4. Broadcast domain

Explanation

An NFS export policy contains rules that specify client match criteria and access permissions, controlling who may mount the volume. Igroups govern block initiators, snapshot policies govern protection, and broadcast domains govern port grouping.

Question 16ONTAP Cluster Fundamentals and Administration

After a node failover in an HA pair, clients lose access to data LIFs hosted on the failed node. What is the most likely explanation?

  1. The SVM was deleted during failover
  2. The LIFs have not been configured for automatic failover to the partner Correct answer.
  3. The cluster interconnect was upgraded
  4. The aggregate was converted to a FlexGroup

Explanation

Data LIFs survive a node failure only if their failover policy and partner port configuration allow them to move to the surviving node. Deletion, volume type changes, and interconnect upgrades are not normal consequences of failover.

Question 17ONTAP Cluster Fundamentals and Administration

An administrator wants to restrict how much space a specific user can consume inside a FlexVol. Which ONTAP feature applies?

  1. Aggregate RAID group size
  2. Quota rules on the volume Correct answer.
  3. LIF failover policy
  4. Snapshot reserve

Explanation

Quota rules define limits for users, groups, or qtrees within a volume and can enforce or track usage. Snapshot reserve, RAID group size, and failover policy govern other aspects of storage and networking.

Question 18ONTAP Cluster Fundamentals and Administration

Which command sequence correctly creates a new volume and mounts it into the SVM namespace?

  1. vserver create, then vserver start
  2. volume mount, then volume create
  3. lun create, then lun map
  4. volume create, then volume mount Correct answer.

Explanation

A volume is first created in an aggregate and then mounted at a junction path to appear in the SVM namespace. Mounting before creation is impossible, LUN commands create block objects, and vserver commands manage the SVM itself.

Question 19ONTAP Cluster Fundamentals and Administration

What does an ONTAP broadcast domain accomplish for network configuration?

  1. It sets the retention period for snapshots
  2. It groups ports that can host the same LIFs and participate in failover together Correct answer.
  3. It encrypts data at rest across aggregates
  4. It defines which users may log in to the cluster

Explanation

A broadcast domain is a set of ports in the same Layer 2 network that LIFs can move between during failover or migration. Encryption, login authorization, and snapshot retention are handled by other features.

Question 20ONTAP Cluster Fundamentals and Administration

An administrator must take over a node's storage during a planned maintenance window while keeping the partner serving data. Which operation is appropriate?

  1. system node reboot
  2. network interface migrate
  3. volume offline
  4. storage failover takeover Correct answer.

Explanation

The storage failover takeover command transfers the node's storage and LIFs to its HA partner so that service continues during maintenance. A plain reboot, taking a volume offline, or migrating a single LIF does not achieve a controlled HA takeover.

Question 21ONTAP Cluster Fundamentals and Administration

A volume is configured with a Snapshot policy that keeps hourly snapshots for two days. Which statement best describes what ONTAP does with older snapshots?

  1. It removes snapshots that fall outside the policy's retention schedule Correct answer.
  2. It converts them into SnapMirror copies
  3. It retains them indefinitely regardless of policy
  4. It moves them to a different aggregate automatically

Explanation

A Snapshot policy defines a schedule and a count, and ONTAP automatically deletes snapshots that exceed the retention defined by the policy. Snapshots are not retained forever, converted to replication, or relocated to other aggregates by the policy.

Question 22ONTAP Cluster Fundamentals and Administration

An administrator needs to confirm which aggregate a particular FlexVol resides in and how much space it consumes. Which command output is most directly relevant?

  1. vserver services name-service dns show
  2. system node show -fields health
  3. network interface show -fields address
  4. volume show -fields aggregate,used,available Correct answer.

Explanation

The volume show command with field selection reports each volume's containing aggregate and its used and available space. Node health, LIF addresses, and DNS settings do not describe volume placement or capacity.

Question 23ONTAP Cluster Fundamentals and Administration

An SVM is configured with both NFS and CIFS, and users report that files created via NFS show unexpected ownership when accessed via CIFS. Which ONTAP mechanism should be examined?

  1. The broadcast domain port list
  2. The LUN's igroup membership
  3. The name-mapping configuration between UNIX and Windows identities Correct answer.
  4. The export policy's anonymous UID mapping

Explanation

In a multiprotocol SVM, name mapping translates UNIX identities to Windows identities and vice versa, so incorrect mappings produce unexpected ownership across protocols. Export policies, igroups, and broadcast domains do not perform identity translation.

Question 24ONTAP Cluster Fundamentals and Administration

An administrator wants to ensure that a newly created SVM can resolve hostnames for CIFS and NFS Kerberos operations. Which configuration is required?

  1. Disable the cluster management LIF
  2. Create a new aggregate for the SVM
  3. Convert the SVM's volumes to FlexGroup
  4. Configure DNS name servers on the SVM Correct answer.

Explanation

Name resolution for the SVM is provided by configuring DNS name servers in the SVM's name-service configuration, which is needed for CIFS and Kerberos operations. Aggregates, management LIFs, and volume type do not provide DNS resolution.

Question 25ONTAP Cluster Fundamentals and Administration

An administrator observes that a FlexVol reports ample free space in the aggregate but writes fail because the volume's nominal size is reached. What is the most likely cause?

  1. The volume has reached its configured maximum size and must be grown Correct answer.
  2. The aggregate has run out of disks
  3. The snapshot policy is disabled
  4. The LIF has failed over to the partner node

Explanation

A thin-provisioned FlexVol still has a logical maximum size; when writes reach that limit, the volume must be resized even if aggregate space remains. Aggregate exhaustion, LIF failover, and snapshot policy state do not explain a nominal-size limit.

Question 26ONTAP Cluster Fundamentals and Administration

In ONTAP, what is the purpose of a Snapshot copy policy when it is assigned to a FlexVol?

  1. It determines which aggregate the volume is placed on during creation.
  2. It controls the maximum number of concurrent CIFS sessions that the SVM may establish.
  3. It defines the schedule and retention count that determine when Snapshot copies are created and how many are kept. Correct answer.
  4. It sets the read-write permission level applied to clients mounting the volume over NFS.

Explanation

A Snapshot policy is a named object that holds a schedule (for example hourly, daily, weekly) and a retention count for each schedule. Assigning it to a volume governs automatic creation and how many copies are retained before older ones are deleted. It has no role in client permissions, session limits, or aggregate placement.

Question 27ONTAP Cluster Fundamentals and Administration

An administrator wants to see the ONTAP event log messages that have been recorded on a specific node, including the time, severity, and description of each event. Which command should be used?

  1. network interface show -vserver svm1
  2. event log show Correct answer.
  3. system node show
  4. volume show -fields state

Explanation

The event log show command displays the event messages recorded for the cluster, including timestamp, severity, and description, and it can be filtered by node or message name. It is the standard way to review EMS-style event records on a node. The other commands report node inventory, volume state, or LIF status rather than event history.

Question 28ONTAP Cluster Fundamentals and Administration

A cluster administrator needs to add a replacement node to an existing ONTAP cluster so the new node participates in the cluster and can host aggregates and LIFs. Which statement describes the correct high-level sequence?

  1. Install and configure ONTAP on the new node, join it to the existing cluster with cluster setup, then verify membership with cluster show. Correct answer.
  2. Add the new node's disks to an existing aggregate, then reboot the cluster so the node is discovered automatically.
  3. Create a new SVM on the new node first, then join the node to the cluster using vserver add.
  4. Run system node modify to rename an existing node, which converts it into the new replacement node.

Explanation

A new node must first have ONTAP installed and its management and cluster networking configured, then it is joined to the existing cluster during cluster setup by supplying the cluster details. After the join, cluster show confirms the node is a member and eligible. Only after membership is established can the node host aggregates and LIFs.

Question 29ONTAP Cluster Fundamentals and Administration

An administrator wants to prevent a specific volume from consuming more than its allotted space while still allowing the aggregate to be shared by other volumes. Which ONTAP mechanism enforces this per-volume limit?

  1. A Snapshot reserve set to zero percent.
  2. An export policy rule restricting the volume to a set of client subnets.
  3. A QoS policy group applied to the volume's LIFs.
  4. The volume's space guarantee and its maximum size, checked against the aggregate's available space. Correct answer.

Explanation

A FlexVol has a configured size and a space guarantee; when the guarantee is enabled, ONTAP reserves that space in the aggregate, and writes beyond the volume size fail regardless of aggregate free space. This is what bounds a single volume's consumption. QoS policies limit throughput or IOPS, not capacity, and export policies and Snapshot reserve do not cap volume size.

Question 30ONTAP Cluster Fundamentals and Administration

An administrator is planning LIF placement for an SVM that must survive the failure of any single node in a four-node cluster. Data LIFs are currently configured with a single home node and no failover targets. What should the administrator do to meet this requirement?

  1. Enable AutoSupport on the SVM so that failed LIFs are recreated on a surviving node.
  2. Create one SVM per node so that each node hosts only its own data LIFs.
  3. Convert the data LIFs to cluster-management LIFs so they can move between nodes automatically.
  4. Assign each data LIF a list of failover targets that includes ports on other nodes, and verify that the ports are reachable on the same broadcast domain. Correct answer.

Explanation

LIF failover requires each data LIF to have failover targets, which are ports on other nodes that share the appropriate network reachability, typically the same broadcast domain or a routed path. Without targets, ONTAP cannot relocate the LIF when its home node fails. Creating additional SVMs or enabling AutoSupport does not provide LIF mobility.

Question 31Storage and Aggregate Management

In ONTAP, which storage object is the unit that a client mounts or that an SVM exposes to clients over NFS or SMB?

  1. An aggregate
  2. A LUN
  3. A disk shelf
  4. A volume Correct answer.

Explanation

A volume is the logical container that holds files and LUNs and is exported by an SVM through a junction path. Aggregates are the underlying physical storage pool, and LUNs are block objects inside a volume.

Question 32Storage and Aggregate Management

Which ONTAP object must exist before you can create a new volume in a cluster?

  1. An igroup
  2. An export policy
  3. A Snapshot policy
  4. An aggregate with available space Correct answer.

Explanation

Every volume is created inside an aggregate, so an aggregate with free capacity must exist first. Snapshot policies, export policies, and igroups are optional associations applied afterward.

Question 33Storage and Aggregate Management

Which statement describes a FlexVol volume in ONTAP?

  1. It is a flexible volume that draws capacity from its containing aggregate and can be resized. Correct answer.
  2. It is a temporary cache that loses data on reboot.
  3. It is a fixed-size partition bound to a single disk.
  4. It is a read-only replica created only by SnapMirror.

Explanation

FlexVol volumes are logically separate from physical disks and can grow or shrink within aggregate limits. They are not tied to a single disk and persist across reboots.

Question 34Storage and Aggregate Management

A volume is reported as offline and clients cannot access it. Which action brings the volume back into service?

  1. Create a new junction path
  2. Restart the NFS server on the SVM
  3. Increase the volume size
  4. Bring the volume online Correct answer.

Explanation

An offline volume is unmounted from its junction and unavailable to clients until it is brought online. Restarting services or resizing does not change the offline state.

Question 35Storage and Aggregate Management

Which ONTAP feature lets you create a volume that shares a single aggregate's free space without pre-allocating a fixed size?

  1. SnapLock volume
  2. Thin-provisioned FlexVol Correct answer.
  3. Infinite Volume
  4. FlexGroup volume

Explanation

A thin-provisioned FlexVol reports its nominal size but consumes aggregate space only as data is written. Infinite Volumes and FlexGroups are distinct scale-out constructs, and SnapLock is a retention feature.

Question 36Storage and Aggregate Management

Which command displays aggregate capacity and available space in ONTAP?

  1. disk show -v
  2. volume show-space
  3. aggregate show -fields size,avail Correct answer.
  4. snapshot policy show

Explanation

The aggregate show command with field selection reports aggregate size and available capacity. The other commands report volume space, disk details, or Snapshot policy configuration.

Question 37Storage and Aggregate Management

What does the junction path of a volume define?

  1. The namespace location where the volume is mounted in the SVM Correct answer.
  2. The IP address clients use to reach the volume
  3. The physical disk that stores the volume
  4. The retention period applied to files

Explanation

The junction path places the volume within the SVM namespace so NFS and SMB clients can reach it. It has no bearing on physical placement, client IP addressing, or retention.

Question 38Storage and Aggregate Management

An administrator wants to guarantee that a critical volume always has space available even when the aggregate is overcommitted. Which setting should be used?

  1. Disable Snapshot autodelete
  2. Enable deduplication on the volume
  3. Convert the volume to a FlexGroup
  4. Set the volume guarantee to volume Correct answer.

Explanation

Setting the space guarantee to volume reserves the volume's full nominal size in the aggregate. Deduplication, Snapshot settings, and FlexGroup conversion do not reserve capacity.

Question 39Storage and Aggregate Management

Which statement correctly distinguishes a FlexGroup volume from a FlexVol volume?

  1. A FlexGroup must reside on a single aggregate node.
  2. A FlexGroup cannot use Snapshot copies.
  3. A FlexGroup stores only LUNs and cannot hold files.
  4. A FlexGroup distributes data across multiple constituents to scale capacity and performance. Correct answer.

Explanation

A FlexGroup is composed of multiple constituent volumes spread across nodes and aggregates, scaling capacity and throughput. It supports Snapshots and file storage and is not confined to one node.

Question 40Storage and Aggregate Management

A volume shows high used capacity but the aggregate still has free space. Which factor most directly limits how large this FlexVol can grow?

  1. The number of LIFs on the SVM
  2. The cluster time zone
  3. The maximum volume size setting and aggregate free space Correct answer.
  4. The export policy rule count

Explanation

A FlexVol can grow only up to its configured maximum size and within remaining aggregate free space. LIF counts, export rules, and time zone do not constrain volume growth.

Question 41Storage and Aggregate Management

What happens to a volume when you delete its parent aggregate?

  1. The volume becomes a FlexGroup.
  2. The volume is converted to read-only.
  3. The operation fails while volumes still reside on the aggregate. Correct answer.
  4. The volume is automatically moved to another aggregate.

Explanation

ONTAP prevents deletion of an aggregate that still contains volumes, so the volumes must be moved or deleted first. The system does not auto-relocate or transform them.

Question 42Storage and Aggregate Management

Which tool allows you to relocate a volume from one aggregate to another without disrupting client access?

  1. disk sanitize
  2. aggregate relocate
  3. snapmirror initialize
  4. volume move start Correct answer.

Explanation

The volume move start command performs a nondisruptive migration of a volume between aggregates. Aggregate relocate, SnapMirror initialize, and disk sanitize perform different functions.

Question 43Storage and Aggregate Management

An aggregate is running low on free space and the administrator wants to reclaim space consumed by old Snapshot copies. Which approach is most appropriate?

  1. Disable thin provisioning on all volumes
  2. Delete the aggregate and recreate it
  3. Convert the aggregate to a FlexGroup
  4. Adjust the Snapshot policy and remove unneeded Snapshot copies Correct answer.

Explanation

Reducing retained Snapshot copies frees the blocks they hold in the aggregate. Deleting the aggregate is destructive, and thin provisioning or FlexGroup conversion does not reclaim Snapshot space.

Question 44Storage and Aggregate Management

Which RAID configuration does ONTAP use by default for aggregates on current AFF and FAS systems?

  1. RAID0
  2. RAID-DP or RAID-TEC Correct answer.
  3. RAID4
  4. RAID1 only

Explanation

ONTAP uses double-parity RAID-DP and, for larger drives, triple-parity RAID-TEC to survive multiple drive failures. RAID0 and RAID1 offer no or limited redundancy, and RAID4 is single parity.

Question 45Storage and Aggregate Management

What is the role of a spare disk in an aggregate?

  1. It holds the cluster configuration database.
  2. It stores Snapshot copies exclusively.
  3. It is available to replace a failed disk and reconstruct the aggregate. Correct answer.
  4. It serves as a read cache for clients.

Explanation

Spare disks are unassigned drives reserved so ONTAP can replace failed members and rebuild redundancy. They are not dedicated to Snapshots, configuration, or caching.

Question 46Storage and Aggregate Management

An administrator needs a volume that can be written to while SnapMirror replication continues to protect it in the opposite direction. Which volume type supports this bidirectional relationship?

  1. A FlexCache volume
  2. A DP destination volume
  3. A SnapLock compliance volume
  4. A load-sharing mirror Correct answer.

Explanation

A load-sharing mirror is a writable mirror that can serve read traffic and participate in replication relationships. A DP destination is read-only, FlexCache caches data, and SnapLock enforces retention.

Question 47Storage and Aggregate Management

Which statement about moving a volume with volume move start is accurate?

  1. The destination must be an aggregate on the same node.
  2. The volume loses its junction path after the move.
  3. The move can be cut over with minimal client disruption after the baseline transfer. Correct answer.
  4. The source volume must be offline for the entire move.

Explanation

Volume move performs a baseline copy, then a brief cutover, keeping disruption minimal. The source stays online, the destination can be on another node, and the junction path is preserved.

Question 48Storage and Aggregate Management

A FlexVol has a space guarantee of none. What is the practical consequence?

  1. The volume is automatically deleted when full.
  2. The volume is forced to be read-only.
  3. The volume consumes aggregate space only as data is written, risking overcommit. Correct answer.
  4. The volume cannot be written to.

Explanation

With a guarantee of none, the volume is thin-provisioned and space is allocated on write, so the aggregate can be overcommitted. The volume remains writable and is not auto-deleted.

Question 49Storage and Aggregate Management

Which consideration most affects whether an aggregate should be created with RAID-TEC rather than RAID-DP?

  1. The version of the ONTAP CLI
  2. The number of NFS exports
  3. The size and rebuild time of the drives in the aggregate Correct answer.
  4. The color of the disk shelf

Explanation

Large-capacity drives take longer to rebuild, increasing the risk of a second failure, so triple-parity RAID-TEC is preferred. Export counts, shelf appearance, and CLI version are irrelevant.

Question 50Storage and Aggregate Management

An administrator wants to shrink a FlexVol below its currently used capacity. What is the expected result?

  1. The resize operation is rejected because the new size is smaller than used space Correct answer.
  2. The volume is automatically converted to a FlexGroup
  3. ONTAP truncates files to fit the new size
  4. The excess data is moved to a spare disk

Explanation

A volume cannot be resized smaller than the space it currently consumes, so the operation fails. ONTAP does not truncate data or relocate it to spare disks automatically.
