WGU Cloud-Deployment-and-Operations - WGU Cloud Deployment and Operations Certification Exam
Question #1 (Topic: demo questions)
(A cloud engineer needs to notify the response team whenever a high-security web server responds
with a 403 Forbidden error. Which two steps can enable this functionality? Choose 2 answers.)
Correct Answer: A, C
Explanation:
To notify a response team when a high-security web server returns a 403 Forbidden error, two key
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).
Question #2 (Topic: demo questions)
(Which action must be used to create a metric filter in the Amazon CloudWatch console?)
Correct Answer: C
Explanation:
To create a metric filter in the Amazon CloudWatch console, the first step is to select a log group from
To create a metric filter in the Amazon CloudWatch console, the first step is to select a log group from
which the log data will be analyzed. A log group contains log streams, and metric filters are applied
to the log data within these groups to extract metrics based on patterns. The WGU Cloud
Deployment and Operations Study Guide (Section 4.2, CloudWatch Logs) specifies that the process
begins by navigating to the CloudWatch console, selecting a log group, and then defining the filter
pattern. Actions like enabling an alarm, defining a trace, or specifying a stream are subsequent or
unrelated steps.
Question #3 (Topic: demo questions)
(How are custom metrics grouped in CloudWatch?)
Correct Answer: A
Explanation:
In Amazon CloudWatch, custom metrics are organized and grouped using namespaces. A namespace
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
Question #4 (Topic: demo questions)
(Which AWS solution can send email based on CloudWatch alarms?)
Correct Answer: D
Explanation:
Amazon CloudWatch alarms can trigger notifications when a metric breaches a defined threshold.
Amazon CloudWatch alarms can trigger notifications when a metric breaches a defined threshold.
The AWS solution designed to send emails based on these alarms is Amazon Simple Notification
Service (SNS). SNS supports sending notifications via email, SMS, and other protocols when
subscribed endpoints are triggered by CloudWatch alarms. The WGU Cloud Deployment and
Operations Study Guide (Section 4.3, Monitoring and Alarms) states that SNS is the primary service
for delivering notifications from CloudWatch, allowing users to configure email subscriptions for
alarm states. Other options like SQS, Amplify, and Kinesis are not designed for this purpose.
Question #5 (Topic: demo questions)
(Which CloudWatch metric filter includes log events with the word ERROR but excludes log events
with the word WARNING?)
Correct Answer: C
Explanation:
A metric filter in Amazon CloudWatch Logs can be used to search for specific terms in log data and
