Answer

They require the user to have cluster-admin privileges to see the logs.

Answer

They eliminate the need for container images.

Question 9

Which THREE of the following are valid components or patterns used in Progressive Delivery with GitOps? (Select THREE)

Accepted Answer

AnalysisTemplates. Argo Rollouts, AnalysisTemplates, and blue-green deployments are all core components and patterns used to achieve progressive delivery within a GitOps ecosystem.

Answer

Git-Branch-Per-Environment

Answer

Argo Workflows

Question 10

Which TWO of the following help ensure successful multi-cluster GitOps rollouts? (Select two)

Accepted Answer

Using canary deployment phases per cluster group.. Phased rollouts and cluster grouping ensure that if a deployment fails, it is contained to a specific set of clusters rather than the entire fleet.

Answer

Deploying to all clusters at the same time.

Answer

Using only one Git repository for all cluster configurations.

Answer

Hardcoding cluster IPs in the manifest files.

Question 11

Which TWO of the following are true about the 'Pull' model in GitOps? (Select two)

Accepted Answer

It improves security by removing the need for cluster credentials in CI.. The pull model uses an internal controller to fetch desired state from Git, which is more secure and reliable than pushing from an external CI system.

Answer

It is only supported for Helm charts.

Answer

It requires opening an inbound port on the cluster firewall.

Answer

It requires the CI pipeline to be active 24/7.

Question 12

Which THREE are standard ways to implement GitOps with Helm?

Accepted Answer

Using a GitOps operator to trigger 'helm install'.. Helm can be used by packaging charts in Git, using a GitOps operator to render templates, or by storing values files in Git.

Answer

Running 'helm upgrade' manually.

Answer

Only storing the chart source code.

Question 13

Which TWO of the following are considered advantages of the GitOps approach?

Accepted Answer

Improved auditability through version-controlled commits.. GitOps improves auditability through Git logs and reduces the risk of manual configuration errors.

Answer

Increased reliance on manual CLI interventions.

Answer

Automatic creation of new business requirements.

Answer

Ability to bypass security protocols.

Question 14

Which TWO of the following are features of progressive delivery in GitOps? (Select two)

Accepted Answer

Gradual traffic shifting between application versions.. Progressive delivery allows for safer deployments by limiting the blast radius through canary or blue-green releases and automated metric-based rollbacks.

Answer

Manually logging into pods to check health.

Answer

Immediate deployment of all changes to the entire cluster.

Answer

Removing all health checks from the application.

Question 15

When implementing multi-cluster GitOps, which THREE components are critical for success? (Select three)

Accepted Answer

Secure communication channel (e.g., mTLS/VPN) between management and targets.. A robust multi-cluster strategy requires a centralized management plane, a way to handle environment-specific differences, and secure connectivity between the hub and spoke clusters.

Answer

A shared database for all clusters to store secrets.

Answer

Uniform network latency across all clusters.

Question 16

Which TWO of the following are essential when using Helm in a GitOps workflow? (Select two)

Accepted Answer
