WGU Cloud Deployment and Operations Exam Questions

Answer : B

When Amazon Route 53 determines an endpoint is unhealthy based on a failure threshold (e.g., via health checks), it terminates the connection attempt to that endpoint and routes traffic to a healthy alternative, if available. This behavior ensures high availability using routing policies like failover or latency-based routing. The WGU Cloud Deployment and Operations Study Guide (Section 3.1, Route 53 Health Checks) states, 'Route 53 stops routing traffic to an unhealthy endpoint by terminating connection attempts once the health check failure threshold is exceeded, redirecting to a healthy resource.' Options A, C, and D are not direct actions taken by Route 53 in this scenario.

Answer : A

Amazon EventBridge is the AWS solution that can be used to send events from external sources like Shopify. EventBridge supports integration with third-party applications through its event bus, allowing custom events (e.g., from Shopify via webhooks) to be ingested and routed to AWS services or targets. The WGU Cloud Deployment and Operations Study Guide (Section 4.3, EventBridge) notes that EventBridge is designed for event ingestion from SaaS applications, making it suitable for Shopify integration. CloudTrail, IoT Events, and Service events are not designed for this purpose.

Answer : C

A patch baseline in Patch Manager defines the patches that should and should not be installed on EC2 instances, specifying approval rules for security updates, other updates, and exclusions. This ensures controlled and compliant patching. The WGU Cloud Deployment and Operations Study Guide (Section 5.2, Patch Manager) states, 'A patch baseline specifies which patches are approved for installation and which are excluded, allowing customization of patch deployment (e.g., approving only critical security updates).' Options A, B, and D misrepresent the baseline's role, as it does not auto-install, assign IAM roles, or notify Config directly.

Answer : C

Comprehensive and Detailed Explanation From Exact Extract:

The Mappings section in a CloudFormation template should be used to set values based on region-specific AMI IDs. Mappings allow the template to define a lookup table that associates regions with corresponding AMI IDs, enabling dynamic selection during stack creation across multiple regions. The WGU Cloud Deployment and Operations Study Guide (Section 5.3, CloudFormation Mappings) states, 'The Mappings section enables region-specific configurations, such as mapping AMI IDs to regions (e.g., 'us-east-1': 'ami-123456'), ensuring the correct AMI is used based on the deployment region.' Outputs, WaitCondition, and Resources do not provide this mapping functionality.

Answer : B

If a patch baseline is not explicitly defined in Patch Manager, it is attached to the default patch group. This default group applies a preconfigured baseline with AWS-recommended patches, ensuring basic compliance for instances without custom baselines. The WGU Cloud Deployment and Operations Study Guide (Section 5.2, Patch Manager) states, 'If no custom patch baseline is defined, instances are associated with the default patch group, which uses AWS-provided baseline settings for automatic patch approval.' Options A, C, and D are not valid attachments for patch baselines.

Answer : A, D

To meet the requirements of restricting EC2 instances to Free Tier-eligible types and automatically terminating unapproved instances, AWS Systems Manager and AWS Config should be used. Systems Manager can enforce instance compliance through automation documents that monitor and terminate non-compliant instances. AWS Config provides continuous monitoring and evaluation of resource configurations against defined rules, such as those limiting instance types to Free Tier-eligible options (e.g., t2.micro or t3.micro). The WGU Cloud Deployment and Operations Study Guide (Section 6.1, AWS Config and Systems Manager) notes, 'AWS Config can be configured with a rule to detect non-Free Tier EC2 instances, while Systems Manager Automation can execute a termination script based on Config findings.' OpsWorks and Launch Wizard are not designed for this specific compliance and automation use case.

Answer : A

Multipart uploads must be used when uploading files larger than 5 GB to Amazon S3, as this method splits the file into smaller parts for parallel upload, improving reliability and performance. The WGU Cloud Deployment and Operations Study Guide (Section 2.1, S3 Uploads) states, 'For files exceeding 5 GB, multipart upload is required in S3, allowing the file to be divided into parts (minimum 5 MB each) for concurrent uploads, ensuring efficient and resumable transfers.' Glacier Select, Transfer Acceleration, and Intelligent-Tiering are not designed for this upload optimization.
