OVHcloud Associate common mistakes

OVHcloud Associate · Understand the traps and how to avoid them.

Mistake 1

Treating a VPS and a Public Cloud instance as interchangeable, so the candidate answers questions about billing granularity, network features, and scaling limits as if both products behaved the same way.

Both are virtual machines with a Linux or Windows image, so surface similarity masks different product logic: VPS is a fixed, flat-rate subscription with limited upgrade paths, while Public Cloud instances are hourly-billed, horizontally scalable, and tied to the OpenStack-derived API and project model. Candidates who only ever used one product generalise from it.

What to do instead

Build a two-column comparison in your notes covering billing model, upgrade/resize path, snapshot behaviour, private network support, and API access for VPS versus Public Cloud instances. When a question names a product, answer strictly within that product's constraints before considering whether the other product would fit better.

Mistake 2

Answering bare metal questions as though any server can be reimaged or have its RAID and partitioning changed at will, ignoring the distinction between customisable dedicated servers and fixed-configuration ranges.

Most candidates' experience is with virtual machines where reinstall is instant and free of constraints. On dedicated hardware, some ranges ship with fixed disk layouts or limited OS support, and reinstall options depend on the range and the boot mode, so the intuitive answer is wrong.

What to do instead

Learn which dedicated ranges allow full customisation (partitioning schemes, RAID levels, choice of OS) and which are delivered as fixed configurations. For any question about changing disk layout or OS, first ask whether the named range supports customisation, then answer.

Mistake 3

Confusing object storage with block storage when answering durability, access-method, and use-case questions, for example proposing object storage as the disk for a running database server.

Both are 'storage' and both are durable, so candidates map them onto the familiar local-disk mental model. They miss that object storage is accessed over HTTP/S3-compatible APIs with no mountable block device, while block storage attaches as a volume to an instance.

What to do instead

Memorise a decision rule: data accessed by an application via API and addressed by key goes to object storage; data needing a filesystem, low-latency random I/O, or a database engine goes to block storage. Practise classifying five workloads (static assets, database files, backups, logs, container images) into the correct service.

Mistake 4

Assuming a snapshot or backup is automatically restorable to a different server, region, or account, and answering recovery questions without checking the scope of the copy.

Snapshots feel like complete copies, and vendors often use the same word for local and replicated copies. Candidates do not distinguish a point-in-time snapshot tied to one volume or instance from a backup that can be restored elsewhere, so they overstate recoverability.

What to do instead

For every storage or backup service you study, write down three facts: where the copy physically lives, what it can be restored onto, and what retention or lifecycle rules apply. Answer recovery questions only from those facts, and treat 'snapshot' and 'backup' as distinct terms unless the documentation equates them.

Mistake 5

Designing a private network and then exposing every service to the public internet because the candidate forgets that a private network alone provides no isolation from inbound traffic without a gateway or firewall policy in front of it.

Private networking is taught as the security answer, so candidates stop there. They overlook that instances on a private network still need a defined path to the internet (gateway, NAT, load balancer) and that inbound filtering is a separate control from network segmentation.

What to do instead

For each scenario, draw the traffic path explicitly: client, public entry point, filtering layer, private subnet, service. State which component performs filtering and which performs routing. If a question asks how to keep a database off the internet, the answer must name both the private attachment and the absence of a public IP or gateway route.

Mistake 6

Answering DDoS and WAF questions by choosing the largest or most expensive protection tier rather than matching the protection layer to the attack type described in the scenario.

Candidates memorise product names and tiers but not what each layer inspects. They cannot tell volumetric flooding apart from application-layer request abuse, so they pick a scrubbing solution for a SQL-injection-style problem or a web application firewall for a bandwidth flood.

What to do instead

Classify attacks by layer before choosing a control: volumetric and protocol floods need traffic scrubbing and anycast absorption; malformed or abusive HTTP requests need a WAF with rule sets; credential stuffing needs rate limiting and bot management. Practise mapping five attack descriptions to the correct layer.

Mistake 7

Ignoring the project model in Public Cloud and answering quota, billing, and access questions as if everything lived in one flat account.

Candidates who use a single project never encounter cross-project behaviour. They miss that resources, quotas, and often billing are scoped per project, and that a user's rights may differ between projects, so questions about 'why can't I create another instance' get the wrong answer.

What to do instead

Learn the hierarchy explicitly: account, then project, then resources. Note which objects are global (identity, billing contacts) and which are per-project (instances, networks, quotas). When a question mentions a limit or a permission failure, check project scope and quota before anything else.

Mistake 8

Treating Hosted Private Cloud as identical to Public Cloud, so the candidate applies self-service instant provisioning and per-hour billing logic to a dedicated, VMware-based environment with its own management plane.

Both are 'cloud' and both offer virtual machines, but Hosted Private Cloud is a dedicated infrastructure with reserved hosts, a separate management interface, and different responsibility split for patching and lifecycle. Candidates who have only used Public Cloud project the same assumptions onto it.

What to do instead

Write a short comparison of the two models covering who manages the hypervisor, how hosts are added, how networking is configured, and how the environment is accessed. For any Hosted Private Cloud question, identify the management plane first, then answer about the resource inside it.

Mistake 9

Conflating authentication with authorisation when answering identity questions, for example describing a role assignment as a way to prove who a user is, or proposing multi-factor authentication as the fix for excessive permissions.

The two concepts are taught together and share vocabulary (users, policies, access). Under time pressure candidates reach for the most familiar control, usually MFA, regardless of whether the question is about proving identity or limiting what an identity may do.

What to do instead

Before answering, label the question: 'who are you' means authentication, 'what may you do' means authorisation, 'prove it later' means audit logging. Match the control to the label: MFA and password policy for the first, roles and least-privilege policies for the second, log retention and review for the third.

Mistake 10

Skipping the operational questions about monitoring, alerting, and incident response because they feel less technical, then guessing on questions about what to do first when a resource fails or a threshold is breached.

Candidates concentrate study time on provisioning and architecture, which feel like the core of the exam, and treat operations as common sense. But operational questions test a specific order of actions and a specific division of responsibility between provider and customer that is not guessable.

What to do instead

Learn the shared-responsibility boundary for each product family and the standard incident sequence: detect via monitoring or alert, confirm scope, contain, remediate, then review. Rehearse two short scenarios (an instance unreachable, a disk filling up) and write the first three actions for each.
