DOL DOL Cloud and Infrastructure Strategy 1 — Questions and Answers
Question 1: What is Infrastructure as Code (IaC) and why is it important for a DevOps Leader?
- Writing documentation for infrastructure setup procedures
- Managing and provisioning infrastructure through machine-readable configuration files to enable repeatability and version control (Correct answer)
- Using a graphical console to configure cloud resources
- Outsourcing infrastructure management to a third-party vendor
Correct answer: Managing and provisioning infrastructure through machine-readable configuration files to enable repeatability and version control
IaC enables teams to provision infrastructure consistently, track changes in version control, and automate provisioning at scale.
Question 2: Which cloud adoption strategy involves moving an application to the cloud with minimal changes to leverage managed services?
- Rehost (lift and shift)
- Refactor (re-architect)
- Replatform (lift and optimize) (Correct answer)
- Retire
Correct answer: Replatform (lift and optimize)
Replatforming moves an application to the cloud with minor optimizations (e.g., switching to a managed database) without a full re-architecture.
Question 3: A DevOps Leader is evaluating cloud providers for a new microservices platform. Which factor is MOST critical from a DevOps perspective?
- The lowest possible per-hour compute cost
- Breadth of managed services, native CI/CD integrations, and container orchestration support (Correct answer)
- Geographic proximity of data centers to the office
- Brand recognition of the cloud provider
Correct answer: Breadth of managed services, native CI/CD integrations, and container orchestration support
Rich managed services and native DevOps tooling reduce operational overhead and accelerate delivery pipelines.
Question 4: What is the purpose of a cloud center of excellence (CCoE) in an enterprise adopting DevOps?
- Centralizing all cloud deployments to reduce team autonomy
- Establishing cloud best practices, governance standards, and enabling teams to self-serve safely (Correct answer)
- Replacing the existing IT operations team
- Negotiating cloud discounts with vendors
Correct answer: Establishing cloud best practices, governance standards, and enabling teams to self-serve safely
A CCoE creates guardrails and shared services that empower teams to move fast while maintaining security, compliance, and cost governance.
Question 5: Which pattern best describes a multi-cloud strategy's primary benefit for resilience?
- Reducing infrastructure costs by 50%
- Avoiding vendor lock-in and improving availability by distributing workloads across multiple providers (Correct answer)
- Simplifying operations by using one cloud provider's tooling
- Enabling faster deployments through provider competition
Correct answer: Avoiding vendor lock-in and improving availability by distributing workloads across multiple providers
Multi-cloud strategies reduce dependency on a single provider, lowering the risk of provider outages causing complete service disruption.
Question 6: What is the role of a service mesh in a microservices-based DevOps architecture?
- Replacing the need for containerization
- Managing inter-service communication, observability, and security policies without changing application code (Correct answer)
- Storing configuration data for microservices
- Automating the build process for each microservice
Correct answer: Managing inter-service communication, observability, and security policies without changing application code
A service mesh (e.g., Istio, Linkerd) handles traffic management, mutual TLS, and telemetry at the infrastructure layer, abstracting these concerns from application code.
