CompTIA Cloud+ Practice Test 26

CompTIA Cloud+ Sample Questions

1 / 10

A cloud administrator is troubleshooting intermittent connectivity failures between on-premises data center and a VPC in the public cloud. The VPN tunnel status reports “up,” but packets are dropping. Other applications are unaffected. The failing service uses UDP and large packets. What is the most probable cause?

MTU is too high causing fragmentation and drops

VPN tunnel encryption algorithm is incompatible

Routing advertisement is incorrect

DNS resolution is failing

Firewall is blocking TCP handshake

2 / 10

Your cloud environment runs containerized workloads using managed Kubernetes clusters. One of the clusters is running many pods in Pending state, with events indicating insufficient CPU. The cluster autoscaler isn’t scaling out. What is a likely cause?

Pod resource requests are too low

Kubernetes API server is down

Persistent volumes are unattached

Node groups are at their maximum size limit

Pod affinity rules preventing placement

3 / 10

During a security audit, you find that cross-account IAM roles allow a partner organization to assume roles into your environment. But logs show that roles were assumed outside allowed hours. You want to enforce context-aware constraints. Which feature should you use?

Enforce MFA only on role assumption

Add time-based conditions in IAM policy

Remove cross-account roles entirely

Use network ACLs to block partner’s CIDR

Use IP address conditions only

4 / 10

Your company uses Infrastructure as Code (IaC) to provision cloud stacks. After a template update, a cloud stack drift is detected (actual resources differ from declared). The drift shows a load balancer is missing SSL certificate association. What is the best remedial action?

Manually attach the SSL certificate and ignore drift

Recreate the stack from scratch

Use the IaC tooling’s “drift remediation” or “reconcile” to make actual match declared

Delete the load balancer and rebuild only that component

Disable drift detection to avoid alerts

5 / 10

Your cloud environment hosts virtual machines (VMs) that process large media files. You notice that during backups, the network link saturates, affecting user traffic. You also see many file-level changes within large files (e.g. video edits). What backup method best minimizes network usage and backup duration?

Full backups each night

Differential backups

Snapshot of the VM and transfer as image

File-level replication

Incremental block-level backups (change tracking)

6 / 10

A developer team is continuously deploying a new service via CI/CD pipeline to a staging environment. Occasionally, a deployment introduces performance regressions that go unnoticed until later. The cloud operations team asks you to improve detection before it reaches production. What design should you implement?

Deploy artifacts directly from developer machines

Configure canary deployments in production

Use blue/green deployment for staging environment

Add performance regression tests in pipeline and monitor key metrics

Increase monitoring sampling interval to reduce noise

7 / 10

You have a hybrid cloud architecture: core services run on private cloud while web front ends are in the public cloud. During disaster simulation, you notice failover time is much slower than expected because DNS failover is delayed. Which DNS strategy best improves failover responsiveness?

Increase TTL on DNS records to 24 hours

Use static DNS records pointing to primary site only

Use short TTL and health-check–based DNS failover

Use CNAMEs with alias records pointing indirectly

Use DNS round-robin across both primary and secondary endpoints

8 / 10

An internal audit reveals that some cloud storage buckets in a public cloud account are unintentionally publicly readable, exposing sensitive internal documents. Your security policy mandates encrypting data at rest and enforcing the least privilege model. Which combination of actions best addresses the issue?

Enable server-side encryption for those buckets, restrict bucket ACLs to private, and review IAM policies for “Everyone” grants

Switch to client-side encryption only and rely on the client to enforce access control

Create a shadow copy of the data in a private bucket and delete the original

Use a VPN tunnel to access those buckets from inside the corporate network

Rely on the cloud provider’s default encryption and assume it protects public objects

9 / 10

Your organization has deployed a new microservice that needs to scale rapidly when demand surges. The service calls a managed database in a remote region. Users in that remote region complain of high latency during bursts. Which approach best mitigates latency while maintaining consistency?

Deploy a read-only replica of the database in the remote region and route read traffic

Use a global distributed database with eventual consistency

Increase the instance size of the remote-region database

Cache query results in a regional in-memory cache

Use DNS-based geo-routing to send all requests to primary region

10 / 10

A cloud operations team receives alerts that CPU utilization across a cluster of application servers is staying above 90% for sustained periods, and users are reporting slowness during peak hours. The team had configured auto-scaling policies earlier but they don’t seem to be triggering. What is the most likely cause?

The monitoring agent is misreporting metrics due to version mismatch

The auto-scaling threshold is set too high relative to baseline load

The cloud provider is experiencing an outage

A security policy is throttling CPU usage

The application’s load balancing is misconfigured

Your score is

The average score is 0%

CV0-004 Practice Questions: Your Ultimate Guide to Passing CompTIA Cloud+

Preparing for the CompTIA Cloud+ CV0-004 certification can be daunting, but using CV0-004 practice questions is one of the most effective ways to ensure success. These questions simulate the real exam environment, helping candidates build confidence, identify knowledge gaps, and refine their test-taking strategies.

🧠 Why CV0-004 Practice Questions Matter

The CV0-004 exam assesses your ability to deploy and manage cloud environments. Practice questions help you:

Understand exam format and question types
Identify weak areas in cloud architecture, security, and troubleshooting
Improve time management under exam conditions
Boost retention through repetition and active recall

Studies show that candidates using practice tests are 40–50% more likely to pass on their first attempt.
