Question 1ExtremeCloud IQ wireless policy and radio design

In ExtremeCloud IQ, what configuration construct groups SSIDs, device templates, port types, and network services so they can be applied together to a set of access points?

  1. A network policy Correct answer.
  2. A radio profile
  3. A device template only
  4. A switch stack

Explanation

A network policy is the central ExtremeCloud IQ construct that bundles one or more SSIDs, device templates, port types, and management/network services such as QoS and VPN. Applying the policy to devices that share a characteristic (such as a site) pushes a consistent configuration to all of them.

Question 2ExtremeCloud IQ wireless policy and radio design

An installer connects a new Extreme Universal AP to a PoE switch port with Internet access. What must be true for the AP to onboard to ExtremeCloud IQ automatically?

  1. The AP must first be flashed via a USB console cable

  3. The AP must be assigned a static public IP address
  4. A controller appliance must be installed on the same VLAN

Explanation

Cloud onboarding works when the AP's serial number is associated with the ExtremeCloud IQ account and the AP can reach the cloud over the network. Once powered and connected, the AP contacts ExtremeCloud IQ, is recognized, and downloads its assigned network policy to become operational in minutes.

Question 3ExtremeCloud IQ wireless policy and radio design

Which term does ExtremeCloud IQ use for the broadcast network name that wireless clients see and connect to within a network policy?

  1. VLAN ID
  2. BSSID
  3. SSID Correct answer.
  4. Device template

Explanation

An SSID (Service Set Identifier) is the wireless network name configured inside a network policy that clients see and join. A WLAN is defined by its SSID along with authentication and other settings.

Question 4ExtremeCloud IQ wireless policy and radio design

When editing a network policy in ExtremeCloud IQ, which deployment option pushes only the changed settings to APs without forcing a reboot in most cases?

  1. Complete Configuration Update
  2. Factory Default Push
  3. Cold Standby Sync

  1. Client mode AP using a wireless connection Correct answer.
  2. USB tethering mode
  3. Bluetooth pairing onboarding
  4. Serial bootstrap onboarding

Explanation

ExtremeCloud IQ supports configuring a client-mode AP that uses a wireless connection to reach the network and onboard when no wired uplink is available. This is useful where running Ethernet to the AP is impractical.

Question 15ExtremeCloud IQ wireless policy and radio design

What does enabling MAC binding on a PPSK SSID accomplish during initial configuration?

  1. It disables encryption for IoT devices
  2. The AP binds each client MAC address to the PPSK it first authenticated with Correct answer.
  3. It forces all clients onto the 6 GHz band
  4. It converts the SSID to open authentication

Explanation

With MAC binding enabled, the Extreme AP acts as a PPSK server and automatically binds a client's MAC address to the PPSK it first used. The server maintains an internal MAC-to-PPSK list, improving control over which devices use each key.

Question 16ExtremeCloud IQ wireless policy and radio design

Where in ExtremeCloud IQ would an administrator define reusable groups of users, each with their own credentials, for PPSK assignment?

  1. Switch port profiles
  2. Radio profiles
  3. Local user groups Correct answer.
  4. Floor-plan zones

Explanation

Local user groups in ExtremeCloud IQ let administrators define sets of users and generate per-user PPSKs. These groups bind the unique keys to users and support self-service or bulk key distribution.

Question 17ExtremeCloud IQ wireless policy and radio design

An organization wants to manage Extreme APs without deploying any on-premises controller hardware. Which architecture does ExtremeCloud IQ provide?

  1. Cloud-based (controller-less) management of APs over the Internet Correct answer.
  2. A mandatory hardware controller in every wiring closet
  3. Peer-to-peer mesh-only management
  4. Standalone APs configured one by one via SSH

Explanation

ExtremeCloud IQ is a cloud-managed platform: APs onboard to the cloud and are managed centrally without requiring an on-premises wireless controller. This simplifies multi-site rollouts and reduces hardware.

Question 18ExtremeCloud IQ wireless policy and radio design

Which authentication type should be selected for an SSID intended for personal/home-style security where every user shares a single static passphrase?

  1. WPA2-Enterprise (802.1X)
  2. WPA2-Personal (PSK) Correct answer.
  3. Open with MAC filtering only
  4. EAP-TLS

Explanation

WPA2-Personal uses a single Pre-Shared Key (PSK) passphrase shared by all clients. It is simple to deploy but, unlike PPSK, every device uses the same key, which limits per-user revocation.

Question 19ExtremeCloud IQ wireless policy and radio design

After staging a network policy, an administrator needs to verify which devices will receive it. What is the correct association step in ExtremeCloud IQ?

  1. Reboot all APs to randomize policy assignment
  2. Delete the device template to force inheritance
  3. Assign the policy to the devices or to a device-classification/location so matching APs adopt it Correct answer.
  4. Disable the cloud connection during assignment

Explanation

Devices receive a configuration by being assigned to (or matching the classification of) a network policy. ExtremeCloud IQ then pushes that policy to the associated APs on deployment.

Question 20ExtremeCloud IQ wireless policy and radio design

Which statement best describes how an Extreme Universal AP behaves immediately after first PoE power-up in a properly prepared ExtremeCloud IQ environment?

  1. It remains offline until manually flashed
  2. It broadcasts an open default SSID permanently
  3. It requires a license key typed at the console
  4. It connects to ExtremeCloud IQ and downloads its settings to become operational within minutes Correct answer.

Explanation

Once connected via PoE with Internet access and registered to the account, the AP automatically connects to ExtremeCloud IQ and downloads all necessary settings, becoming fully operational in a few minutes. This zero-touch flow is a core deployment feature.

Question 21ExtremeCloud IQ wireless policy and radio design

An administrator must apply different settings to lobby APs versus warehouse APs at the same site. What is the most scalable ExtremeCloud IQ approach?

  1. Configure each AP individually by IP
  2. Use separate network policies (or per-area device settings) assigned to each group of APs Correct answer.
  3. Disable the cloud and use local CLI only
  4. Put all APs in one open SSID

Explanation

Differentiated requirements are handled by assigning distinct network policies or area-specific settings to each group of APs. This keeps configuration consistent and scalable across many devices.

Question 22ExtremeCloud IQ wireless policy and radio design

What is the purpose of a port type definition within a device template in ExtremeCloud IQ?

  1. It sets the AP transmit power
  2. It selects the country regulatory domain
  3. It defines how a physical wired port behaves, such as access or trunk and its VLANs Correct answer.
  4. It enables WPA3 on the SSID

Explanation

A port type specifies how a physical wired port operates, including access versus trunk mode and associated VLANs. Device templates reference port types so the policy correctly configures each model's interfaces.

Question 23ExtremeCloud IQ wireless policy and radio design

Which best practice ensures an AP gets the correct regulatory channels and power limits at deployment time?

  1. Leaving the country/regulatory domain unset
  2. Using only the 6 GHz band everywhere
  3. Disabling DFS globally
  4. Setting the correct country/regulatory domain for the AP's location Correct answer.

Explanation

Setting the correct country or regulatory domain ensures the AP uses legal channels, power levels, and DFS behavior for its location. Misconfiguring this can cause non-compliant operation or unusable channels.

Question 24ExtremeCloud IQ wireless policy and radio design

An installer needs to confirm that a freshly onboarded AP successfully pulled its configuration. Which ExtremeCloud IQ indicator most directly confirms this?

  1. The AP shows as connected/managed with its assigned network policy applied Correct answer.
  2. The AP's serial number changes
  3. The switch reports a PoE fault
  4. The cloud account shows zero devices

Explanation

A successfully onboarded AP appears in ExtremeCloud IQ as connected and managed, with its assigned network policy applied and broadcasting the expected SSIDs. This is the direct confirmation that configuration was downloaded.

Question 25ExtremeCloud IQ wireless policy and radio design

Which ExtremeCloud IQ feature lets an administrator pre-stage configuration and assign a network policy before the physical AP ever arrives on site?

  1. Powering the AP off permanently
  2. Disabling onboarding in the account
  3. Adding the device by serial number and assigning it to a policy/location in advance Correct answer.
  4. Reformatting the AP firmware remotely

Explanation

Because onboarding is serial-number driven, an administrator can add the AP by serial number and assign its network policy and location in advance. When the AP is later powered on site, it onboards and applies the pre-staged configuration automatically.

Question 26ExtremeCloud IQ wireless policy and radio design

Which IEEE standard, marketed as Wi-Fi 6, introduces OFDMA and BSS coloring while operating in the 2.4 GHz and 5 GHz bands?

  1. 802.11ac
  2. 802.11n
  3. 802.11g
  4. 802.11ax Correct answer.

Explanation

802.11ax is the Wi-Fi 6 standard. It introduces OFDMA, BSS coloring, 1024-QAM, and Target Wake Time while operating in the 2.4 GHz and 5 GHz bands; Wi-Fi 6E extends 802.11ax into 6 GHz.

Question 27ExtremeCloud IQ wireless policy and radio design

What does OFDMA add to Wi-Fi 6 compared with the OFDM used in earlier standards?

  1. It divides a channel into resource units so multiple clients can transmit simultaneously Correct answer.
  2. It doubles the maximum channel width to 320 MHz
  3. It removes the need for any encryption
  4. It eliminates the 2.4 GHz band

Explanation

OFDMA subdivides a channel into smaller resource units (RUs), allowing the AP to serve multiple clients within a single transmission. This improves efficiency and reduces latency, especially for many small-frame clients in high-density areas.

Question 28ExtremeCloud IQ wireless policy and radio design

How many bits is the BSS color identifier defined in 802.11ax, and what problem does it primarily solve?

  1. A 12-bit color used to encrypt management frames
  2. A 6-bit color used to improve spatial reuse by distinguishing overlapping BSSs Correct answer.
  3. A 2-bit color used to select the country code
  4. A 16-bit color used to assign VLANs

Explanation

BSS coloring assigns each BSS a 6-bit color identifier carried in frames so devices can distinguish their own network from overlapping neighboring BSSs on the same channel. This improves spatial reuse and reduces unnecessary deferrals in dense deployments.

Question 29ExtremeCloud IQ wireless policy and radio design

Which band is added by Wi-Fi 6E, and what is one key advantage of its 160 MHz channels over 5 GHz?

  1. The 3.5 GHz band, with mandatory radar avoidance
  2. The 60 GHz band, used for mesh only
  3. The 900 MHz band, for IoT
  4. The 6 GHz band, where 160 MHz channels are free of the DFS restrictions that apply to 160 MHz channels in 5 GHz Correct answer.

Explanation

Wi-Fi 6E extends 802.11ax into the 6 GHz band, which offers many additional wide channels. Its 160 MHz channels avoid the Dynamic Frequency Selection (DFS) constraints that apply to 160 MHz channels in 5 GHz, simplifying wide-channel deployment.

Question 30ExtremeCloud IQ wireless policy and radio design

In the 2.4 GHz band, which set of channels is recommended to avoid co-channel and adjacent-channel interference in most regions?

  1. 1, 6, and 11 Correct answer.
  2. 1 through 14 all at once
  3. 36, 40, 44
  4. Any three consecutive channels

Explanation

Channels 1, 6, and 11 are the standard non-overlapping 20 MHz channels in 2.4 GHz, spaced to avoid adjacent-channel overlap. Using overlapping channels causes interference and degrades performance.

Question 31ExtremeCloud IQ wireless policy and radio design

In a high-density 5 GHz deployment, why is using narrower channel widths such as 20 MHz or 40 MHz often preferred over 80 MHz?

  1. Narrower channels always provide higher per-client throughput
  2. Narrower channels reduce co-channel interference and provide more non-overlapping channels for reuse Correct answer.
  3. Narrower channels disable encryption overhead
  4. Narrower channels remove the need for RRM

Explanation

Wider channels bond more spectrum, leaving fewer non-overlapping channels and increasing co-channel interference in dense AP deployments. Narrower widths give more reusable channels, improving overall capacity even if a single client's peak rate is lower.

Question 32ExtremeCloud IQ wireless policy and radio design

What is the primary function of Radio Resource Management (RRM) on an ExtremeCloud IQ wireless network?

  1. To assign VLANs to wired ports
  2. To generate per-user PPSKs
  3. To automatically tune channel and transmit power across APs to optimize the RF environment Correct answer.
  4. To enforce captive portal acceptance

Explanation

RRM dynamically selects channels and adjusts transmit power across APs to minimize interference and balance coverage. This automated RF optimization adapts to changing conditions without manual per-AP tuning.

Question 33ExtremeCloud IQ wireless policy and radio design

When all clients on an SSID support WPA3, which key-management method should be selected, and what does it use to resist offline dictionary attacks?

  1. WPA3-Personal using SAE (Simultaneous Authentication of Equals) Correct answer.
  2. WPA2-Personal using PSK only
  3. WEP with shared key
  4. Open authentication

Explanation

WPA3-Personal uses SAE (Simultaneous Authentication of Equals), a password-authenticated key exchange that resists offline dictionary attacks even with weak passphrases. ExtremeCloud IQ notes WPA3 (SAE) is the better choice when all clients support it, and it always uses 128-bit encryption.

Question 34ExtremeCloud IQ wireless policy and radio design

An administrator wants strong per-user keys that are simpler to deploy than 802.1X and suitable for IoT devices. Which Extreme feature fits best?

  1. WEP
  2. Private Pre-Shared Key (PPSK) Correct answer.
  3. Open SSID with hidden broadcast
  4. MAC spoof allow-list

Explanation

PPSK gives each user or device a unique pre-shared key while avoiding the deployment complexity of 802.1X, making it well suited to IoT and mixed environments. Extreme positions PPSK as part of a multi-layered strategy alongside 802.1X.

Question 35ExtremeCloud IQ wireless policy and radio design

A team needs to deploy a secure IoT SSID on the 6 GHz band. Which constraint must they account for regarding PPSK?

  1. PPSK only works on 6 GHz
  2. PPSK requires WEP fallback on 6 GHz
  3. PPSK is not available on the 6 GHz band Correct answer.
  4. PPSK forces 20 MHz channels on 6 GHz

Explanation

Private Pre-Shared Key is not supported on the 6 GHz band; 6 GHz mandates stronger security baselines such as WPA3. Teams needing per-device keys on 6 GHz must use an alternative such as WPA3 with appropriate authentication.

Question 36ExtremeCloud IQ wireless policy and radio design

Question 37ExtremeCloud IQ wireless policy and radio design

Which 802.11 amendment provides BSS Transition Management (BTM), allowing the network to steer a client toward a better AP?

  1. 802.11a
  2. 802.11v Correct answer.
  3. 802.11b
  4. 802.11g

Explanation

802.11v defines Wireless Network Management, including BSS Transition Management (BTM), which lets the network suggest or steer a client to a better AP. The BTM request can include a candidate neighbor list.

Question 38ExtremeCloud IQ wireless policy and radio design

Which 802.11 amendment enables Fast BSS Transition, pre-establishing security keys so voice clients roam between APs with minimal handoff delay?

  1. 802.11k
  2. 802.11n
  3. 802.11r Correct answer.
  4. 802.11ac

Explanation

802.11r (Fast BSS Transition) lets a client pre-authenticate and reestablish security and QoS parameters before reassociating to a new AP. This dramatically reduces roaming handoff time, which is critical for voice and real-time applications.

Question 39ExtremeCloud IQ wireless policy and radio design

Which technology grouping does Extreme commonly combine to deliver fast, seamless enterprise roaming?

  1. WEP, WPS, and DFS
  2. PoE, USB, and Bluetooth
  3. QoS, NAT, and DHCP only
  4. 802.11k neighbor reports, 802.11v BTM, and 802.11r fast transition Correct answer.

Explanation

The 802.11k/v/r trio works together: 802.11k provides neighbor lists, 802.11v steers clients via BTM, and 802.11r pre-establishes keys for fast handoff. Together they minimize roaming gaps for latency-sensitive traffic.

Question 40ExtremeCloud IQ wireless policy and radio design

In an outdoor area without wired uplinks to every AP, which deployment mode lets APs wirelessly backhaul traffic to a root AP that has Ethernet?

  1. Wireless mesh Correct answer.
  2. Captive portal mode
  3. OFDMA scheduling
  4. Band steering

Explanation

A wireless mesh lets non-root APs backhaul traffic over the air to a root AP that has a wired uplink, extending coverage where cabling is impractical. Mesh links and roaming are part of advanced wireless design.

Question 41ExtremeCloud IQ wireless policy and radio design

Which Wi-Fi QoS mechanism, based on 802.11e, prioritizes traffic into access categories such as voice, video, best effort, and background?

  1. WPS
  2. WEP
  3. WMM (Wi-Fi Multimedia) Correct answer.
  4. WDS

Explanation

WMM (Wi-Fi Multimedia) implements 802.11e QoS by mapping traffic into four access categories (voice, video, best effort, background) with different contention parameters. This prioritizes latency-sensitive traffic like voice over the air.

Question 42ExtremeCloud IQ wireless policy and radio design

An administrator enables band steering on a dual-band SSID. What is its primary goal?

  1. To force all clients to 2.4 GHz
  2. To disable the 5 GHz radio
  3. To increase WEP key length
  4. To encourage dual-band-capable clients to use the less congested 5 GHz (or 6 GHz) band instead of 2.4 GHz Correct answer.

Explanation

Band steering nudges capable clients onto the higher, typically less congested band (5 GHz or 6 GHz), relieving the crowded 2.4 GHz band. This improves overall capacity and client experience.

Question 43ExtremeCloud IQ wireless policy and radio design

Which Wi-Fi 6 feature schedules when client devices wake to transmit or receive, primarily to extend battery life on IoT devices?

  1. Target Wake Time (TWT) Correct answer.
  2. BSS coloring
  3. 1024-QAM
  4. DFS

Explanation

Target Wake Time (TWT) negotiates scheduled wake periods so devices can sleep longer between transmissions, significantly reducing power consumption. It is especially valuable for battery-powered IoT clients.

Question 44ExtremeCloud IQ wireless policy and radio design

An administrator must select 160 MHz channels in the 5 GHz band that overlap DFS frequencies. What behavior must be planned for?

  1. Encryption will automatically downgrade to WEP
  2. Radar detection may force a channel change (DFS), briefly affecting that radio Correct answer.
  3. The SSID will stop broadcasting permanently
  4. Clients will be moved to 2.4 GHz forever

Explanation

DFS channels require the AP to monitor for radar; if radar is detected, the AP must vacate the channel, causing a brief disruption while it moves. Planning for DFS events is part of wide-channel 5 GHz design.

Question 45ExtremeCloud IQ wireless policy and radio design

Which modulation, introduced in Wi-Fi 6, packs more bits per symbol to raise peak data rates in good RF conditions?

  1. BPSK
  2. QPSK
  3. 16-QAM
  4. 1024-QAM Correct answer.

Explanation

Wi-Fi 6 adds 1024-QAM, encoding 10 bits per symbol, which boosts peak throughput when the signal-to-noise ratio is high. Lower-order modulations are used when conditions are poorer.

Question 46ExtremeCloud IQ wireless policy and radio design

When designing RF coverage, what does cell overlap of roughly 15-20% at the cell edge primarily support?

  1. Seamless roaming so clients can hand off before losing signal Correct answer.
  2. Higher transmit power requirements
  3. Mandatory use of 6 GHz
  4. Elimination of the need for RRM

Explanation

Designing adjacent cells to overlap modestly ensures a client always has a strong candidate AP to roam to before its current signal drops too low. Too little overlap causes sticky clients and dropped sessions at edges.

Question 47ExtremeCloud IQ wireless policy and radio design

Which statement about WPA3-Personal transition mode is correct when an SSID must support both WPA2 and WPA3 clients?

  1. Transition mode disables encryption for legacy clients
  2. Transition mode lets WPA2 (PSK) and WPA3 (SAE) clients connect to the same SSID during migration Correct answer.
  3. Transition mode is only available on 2.4 GHz
  4. Transition mode forces all clients to WEP

Explanation

WPA3-Personal transition mode allows WPA2-PSK and WPA3-SAE clients to share one SSID during a migration period, easing the move to WPA3 without immediately dropping legacy devices. Once all clients support WPA3, SAE-only is preferred.

Question 48ExtremeCloud IQ wireless policy and radio design

Which EAP method uses client and server digital certificates for mutual authentication, generally considered the strongest 802.1X option?

  1. EAP-MD5
  2. LEAP
  3. EAP-TLS Correct answer.
  4. PAP

Explanation

EAP-TLS uses certificates on both the client and server for mutual authentication, providing very strong, phishing-resistant 802.1X security. It avoids password-based weaknesses but requires a PKI to issue and manage certificates.

Question 49ExtremeCloud IQ wireless policy and radio design

An administrator needs to limit the maximum transmit power on APs in a dense office to control cell size. Where is this best handled?

  1. Through the radio profile or RRM transmit-power settings in the network policy Correct answer.
  2. By editing the captive portal HTML
  3. By changing the PPSK length
  4. By disabling the wired uplink

Explanation

Transmit power limits are set in the radio profile or governed by RRM power management within the policy, letting administrators shrink cell size and reduce co-channel interference in dense areas. Smaller cells with good overlap improve roaming and capacity.

Question 50ExtremeCloud IQ wireless policy and radio design

Which design goal is best served by enabling MU-MIMO together with OFDMA in a high-client-density Wi-Fi 6 environment?

  1. Guaranteeing every client a 160 MHz channel
  2. Serving multiple clients more efficiently per transmission opportunity to raise aggregate capacity Correct answer.
  3. Eliminating the need for any RF planning
  4. Forcing all clients onto WPA2-PSK

Explanation

MU-MIMO transmits to multiple clients spatially while OFDMA divides a channel among clients in the frequency domain; together they raise aggregate efficiency in dense environments. This improves capacity for many concurrent clients rather than a single client's peak rate.
