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 : B, C

To meet the requirements, the administrator should use an Amazon RDS Multi-AZ DB instance for multiple Availability Zones and failover support, and an Amazon Aurora DB instance with Aurora Replica for a read-only connection. The RDS Multi-AZ configuration automatically provisions a standby instance in a different AZ for failover, while Aurora Replicas provide read-only instances for scaling read traffic. The WGU Cloud Deployment and Operations Study Guide (Section 7.1, RDS and Aurora) states, 'RDS Multi-AZ deploys a standby instance across AZs for failover, and Aurora Replicas are read-only instances that enhance performance by offloading read traffic from the primary instance.' Options A and D are incorrect as multi-master replication and Multi-AZ clusters do not align with the read-only requirement.

Answer : A

In Amazon CloudWatch, custom metrics are organized and grouped using namespaces. A namespace is a container for CloudWatch metrics that allows you to isolate and categorize metrics from different applications or services. According to the WGU Cloud Deployment and Operations Study Guide (Section 4.1, CloudWatch Metrics), each custom metric must be assigned to a namespace, which acts as a unique identifier to prevent naming collisions and facilitate metric management. Options like Service, Date, and Value are not used for grouping metrics in this context.

Answer : A, C

To notify a response team when a high-security web server returns a 403 Forbidden error, two key steps are required. First, define a metric filter for Apache logs in CloudWatch to detect the 403 error code within the log data. This involves setting up a filter pattern to match '403' in the Apache access logs. Second, create an alarm for the metric filter and configure it to deliver alerts using Amazon SNS, which supports email or other notifications to the response team. The WGU Cloud Deployment and Operations Study Guide (Section 4.2, CloudWatch Logs and Alarms) confirms that metric filters and SNS-integrated alarms are the standard approach for monitoring and alerting on log-based events. Options B and D are incorrect as they involve unnecessary or unsupported configurations (e.g., binding Lambda to Apache or using SQS for alarms).

Answer : C

Comprehensive and Detailed Explanation From Exact Extract:

To reduce latency in region B due to increased demand for media files stored in region A, cross-region replication (CRR) should be used. CRR replicates objects to an S3 bucket in another region (e.g., region B), allowing users to access files from a closer location, thus minimizing latency. The WGU Cloud Deployment and Operations Study Guide (Section 2.2, S3 Replication) states, 'Cross-Region Replication in S3 copies objects to a destination bucket in a different region, reducing latency by enabling access to data from the nearest region, such as region B in this case.' S3 Batch, S3 Versioning, and Same-Region replication do not address cross-region latency.
