CGOA Timed Practice Test 2 — 10 Questions

Question 1

What is the primary benefit of using a 'Git Branch' promotion pattern over a 'Directory-based' promotion pattern?

Accepted Answer

It allows teams to use PRs to review configuration changes for specific environments.. Branch-based promotion allows for better isolation of changes, enabling PR reviews for individual environments and preventing accidental merges to production.

Answer

It eliminates the need for CI pipelines.

Answer

It requires less storage space in the Git repository.

Answer

It automatically synchronizes all branches to the cluster simultaneously.

Question 2

Why should you avoid using 'latest' as a container image tag in GitOps?

Accepted Answer

It prevents the controller from knowing exactly what version is deployed.. Using 'latest' makes the deployment non-deterministic because the image associated with the tag can change, making it impossible to know exactly what is running in the cluster.

Answer

It causes the cluster to crash.

Answer

It's slower to pull.

Answer

It requires more storage space.

Question 3

Which TWO of the following are common reasons for a deployment to be marked as 'Degraded' by Argo CD? (Select two)

Accepted Answer

The health checks defined for the application are failing.. 'Degraded' status often occurs when pods fail to start (e.g., CrashLoopBackOff) or when health checks defined in the manifest are not met.

Answer

The user manually changed a label.

Answer

The Argo CD controller is overloaded.

Answer

The Git repository is temporarily offline.

Question 4

What is the recommended way to handle secrets in GitOps?

Accepted Answer

Use an encrypted secret operator like SealedSecrets.. Secrets should never be stored in plaintext. Tools like SealedSecrets or HashiCorp Vault integration are standard.

Answer

Commit them directly to the repo in a private branch.

Answer

Create them manually using kubectl.

Answer

Store them in base64 in Git.

Question 5

Which TWO benefits does GitOps provide for team collaboration?

Accepted Answer

Providing a transparent, versioned history of infrastructure changes.. GitOps fosters collaboration by leveraging pull requests for peer reviews and providing a single, transparent record of all changes.

Answer

Removing the need for communication.

Answer

Forcing everyone to use the same IDE.

Answer

Allowing developers to deploy without oversight.

Question 6

Which THREE activities are part of the 'Automated Pull-Based Reconciliation' process?

Accepted Answer

Applying updates to the cluster API.. The process involves detecting changes, fetching manifests, and applying them.

Answer

Sending a push notification to developers.

Answer

Compiling binaries on the local cluster node.

Question 7

In GitOps, what is the 'Source of Truth'?

Accepted Answer

The Git repository.. The Git repository is the single source of truth for the desired state of the infrastructure and applications.

Answer

The running Kubernetes cluster.

Answer

The CI pipeline logs.

Answer

The container registry.

Question 8

Which TWO of the following configurations are necessary to ensure that GitOps-managed clusters in a multi-cluster setup remain isolated from one another? (Select TWO)

Accepted Answer

Implementing unique namespaces for each application.. Using dedicated AppProjects per cluster and strict namespace-level RBAC ensures that GitOps controllers cannot accidentally deploy or interfere with resources in unauthorized clusters.

Answer

Disabling the GitOps controller on the management cluster.

Answer

Using the same Git repository for all clusters.

Answer

Enabling 'automated.prune' on all applications.

Question 9

When managing multiple environments (dev/stage/prod) in one repository, which folder structure is generally considered best practice?

Accepted Answer

Using environment-specific folders.. Keeping environment configurations in separate folders (e.g., /overlays/dev, /overlays/prod) allows for clear separation and prevents accidental configuration bleeding.

Answer

Storing configurations in the application code folder.

Answer

Putting everything in a single root folder.

Answer

Using different Git repos for every single manifest.

Question 10

Which THREE of the following are common challenges when scaling GitOps to hundreds of clusters? (Select three)

Accepted Answer

Automatic rollbacks when the Git repo is empty.. Scaling challenges include managing the overhead of the controller, handling secret distribution, and ensuring that temporary outages do not lead to massive drift across the fleet.

Answer

The need for a dedicated team just to write Dockerfiles.

Answer

Increased dependency on internet speed.
