Question 1

A company is moving a 10 TB SQL Server database to Azure SQL Database. They need to migrate with minimal downtime while keeping the source database operational. Which service should they use?

Accepted Answer

Azure Database Migration Service (DMS). Azure Database Migration Service supports online migrations with minimal downtime using continuous sync (CDC) from SQL Server to Azure SQL Database.

Answer

Azure Data Sync

Answer

Azure Import/Export Service

Answer

Azure Data Box

Question 2

A cloud architect is designing a CI/CD pipeline for a microservices application deployed on a managed Kubernetes service. The pipeline should include stages for source, build, test, deploy, and verify. Which TWO of the following are typical pipeline stages? (Select TWO.)

Accepted Answer

Build. (Build) is correct because in a CI/CD pipeline for AWS EKS, the Build stage compiles source code, runs unit tests, and creates container images (e.g., using Docker) that are pushed to a registry like Amazon ECR. This stage is essential for transforming code into deployable artifacts for Kubernetes workloads.

Answer

Audit

Answer

Backup

Answer

Monitor

Question 3

A company is migrating on-premises storage to Google Cloud Storage (GCS) using Storage Transfer Service. The source is an on-premises NAS with 100 TB of data. Which THREE considerations are relevant for this migration? (Select THREE.)

Accepted Answer

The possibility to schedule periodic transfers for ongoing sync. Storage Transfer Service supports online transfers from sources like Amazon S3, HTTP/HTTPS, and on-premises via a staging area. Bandwidth, data integrity, and transfer time are key considerations.

Answer

Requirement to install an agent on the NAS

Answer

The need for a physical appliance like Snowball Edge

Question 4

A cloud engineer is using Terraform to manage infrastructure. They need to store the state file remotely for team collaboration and to enable state locking. Which THREE of the following backends support state locking? (Select THREE.)

Accepted Answer

Consul backend. The correct answers are Consul backend, Azure Blob Storage with blob lease, and Amazon S3 with DynamoDB, as all three support state locking.

Answer

Local file system

Answer

HTTP backend

Question 5

A cloud engineer is managing AWS infrastructure with Terraform and wants to store the state file remotely to enable team collaboration. Which storage option should the engineer configure in the backend block?

Accepted Answer

Amazon S3. Terraform supports multiple remote backends. For AWS, S3 is the recommended backend for storing state files, providing durability and locking via DynamoDB.

Answer

Google Cloud Storage

Answer

Local file system

Answer

Azure Blob Storage

Question 6

An organization wants to deploy a new application with zero downtime by switching traffic between two identical production environments. Which deployment strategy should be used?

Accepted Answer

Blue/green deployment. Blue/green deployment involves maintaining two identical environments; traffic is switched from the old (blue) to the new (green) environment via DNS or load balancer, enabling zero downtime.

Answer

Rolling deployment

Answer

Canary deployment

Answer

In-place deployment

Question 7

A company is migrating a 50 TB on-premises SQL Server database to Amazon RDS for MySQL with minimal downtime. The schema must be converted from SQL Server to MySQL. Which combination of AWS services should the cloud architect use?

Accepted Answer

AWS DMS and AWS Schema Conversion Tool (SCT). AWS DMS can migrate data with minimal downtime using CDC. Schema Conversion Tool (SCT) converts the schema from SQL Server to MySQL. DMS then performs the ongoing replication.

Answer

AWS Database Migration Service (DMS) only

Answer

AWS Snowball and AWS DMS

Answer

AWS DataSync and AWS Schema Conversion Tool (SCT)

Question 8

A DevOps team uses CloudFormation to manage multi-account infrastructure. They need to deploy a common set of resources across multiple AWS accounts in an organization. Which CloudFormation feature should they use?

Accepted Answer

Stack sets. CloudFormation StackSets allow you to deploy stacks across multiple accounts and regions from a single template, ideal for multi-account scenarios.

Answer

Nested stacks

Answer

Drift detection

Answer

Change sets

Question 9

A cloud engineer is creating an Ansible playbook to provision cloud resources on AWS. Ansible is agentless; it connects to managed nodes via SSH. Which component defines the desired state of cloud resources in Ansible?

Accepted Answer

Modules. Ansible uses modules to interact with cloud APIs. AWS modules, such as ec2, define the desired state of resources like EC2 instances.

Answer

Playbooks

Answer

Roles

Answer

Inventory

Question 10

A company wants to deploy a Lambda function that processes objects uploaded to an S3 bucket. Which event trigger should be configured on the Lambda function?

Accepted Answer

S3 bucket event notification. S3 bucket event notifications can be configured to directly invoke a Lambda function when objects are uploaded. This is the native, serverless integration where S3 publishes an event (e.g., s3:ObjectCreated:Put) to Lambda, triggering the function automatically without any intermediary service.

Answer

API Gateway

Answer

CloudWatch Events

Answer

SQS

Question 11

A company needs to transfer 200 TB of data from an on-premises NAS to Amazon S3 over the internet within 5 days. The available bandwidth is 1 Gbps. Which AWS service should be used to accelerate the transfer?

Accepted Answer

AWS DataSync. AWS DataSync can accelerate transfers over the internet using parallel multi-threading and compression. Snowball would be faster for 200 TB, but the question specifies over the internet. DataSync is optimized for network transfers.

Answer

AWS Snowball

Answer

S3 Transfer Acceleration

Answer

AWS Direct Connect

Question 12

A developer wants to deploy a containerized application on a Kubernetes cluster using a package manager that simplifies deployment and management. Which tool should be used?

Accepted Answer

Helm. Helm is the package manager for Kubernetes. It uses charts to define, install, and upgrade complex Kubernetes applications.

Answer

Docker Compose

Answer

Terraform

Answer

Ansible

Question 13

A cloud engineer is writing a Bicep file to deploy Azure resources. Bicep is a domain-specific language (DSL) that transpiles to ARM templates. Which of the following is a benefit of using Bicep over ARM JSON templates?

Accepted Answer

Bicep reduces code verbosity and supports modules. Bicep provides a simpler syntax with less boilerplate, modularity, and reusable modules. It reduces complexity compared to raw ARM JSON.

Answer

Bicep automatically manages state

Answer

Bicep is natively executed by Azure Resource Manager

Answer

Bicep supports imperative scripting

Question 14

A company uses GitLab CI for its CI/CD pipeline. The pipeline includes a 'deploy' job that runs only when a tag is pushed. Which GitLab CI keyword should be used to control job execution based on tags?

Accepted Answer

only. The 'only' keyword (or 'rules') in GitLab CI specifies conditions for job execution. 'only: tags' ensures the job runs only for tags.

Answer
