A company has a mobile application that makes HTTP API calls to an
Application Load Balancer (ALB). The ALB routes requests to an AWS
Lambda function. Many different versions of the application are in use at
any given time, including versions that are in testing by a subset of users.
The version of the application is defined in the user-agent header that is
sent with all requests to the API. After a series of recent changes to the
,Terms in this set (100) Q&A
API, the company has observed issues with the application. The company
needs to gather a metric for each API operation by response code for each
version of the application that is in use. A DevOps engineer has modified
the Lambda function to extract the API operation name, version information
from the user-agent header and response code. Which additional set of
actions should the DevOps engineer take to gather the required metrics? -
B. Modify the Lambda function to write the API operation name, response
code, and version number as a log line to an Amazon CloudWatch Logs log
group. Configure a CloudWatch Logs Insights query to populate
CloudWatch metrics from the log lines. Specify response code and
application version as dimensions for the metric.
A company provides an application to customers. The application has an
Amazon API Gateway REST API that invokes an AWS Lambda function.
On initialization, the Lambda function loads a large amount of data from an
Amazon DynamoDB table. The data load process results in long cold-start
times of 8-10 seconds. The DynamoDB table has DynamoDB Accelerator
(DAX) configured. Customers report that the application intermittently takes
a long time to respond to requests. The application receives thousands of
requests throughout the day. In the middle of the day, the application
experiences 10 times more requests than at any other time of the day.
Near the end of the day, the application's request volume decreases to
10% of its normal total. A DevOps engineer needs to reduce the latency of
the Lambda function at all times of the day. Which solution will meet these
requirements? - C. Configure provisioned concurrency on the Lambda
function. Configure AWS Application Auto Scaling on the Lambda function
with provisioned concurrency values set to a minimum of 1 and a maximum
of 100.

A company is adopting AWS CodeDeploy to automate its application
deployments for a Java-Apache Tomcat application with an Apache
Webserver. The development team started with a proof of concept, created
a deployment group for a developer environment, and performed functional
tests within the application. After completion, the team will create additional
deployment groups for staging and production. The current log level is
configured within the Apache settings, but the team wants to change this
configuration dynamically when the deployment occurs, so that they can
set different log level configurations depending on the deployment group
without having a different application revision for each group. How can
these requirements be met with the LEAST management overhead and
without requiring different script versions for each deployment group? - B.
Create a script that uses the CodeDeploy environment variable
DEPLOYMENT_GROUP_NAME to identify which deployment group the
instance is part of. Use this information to configure the log level settings.
Reference this script as part of the BeforeInstall lifecycle hook in the
appspec.yml file.
A company requires its developers to tag all Amazon Elastic Block Store
(Amazon EBS) volumes in an account to indicate a desired backup
frequency. This requirement includes EBS volumes that do not require
backups. The company uses custom tags named Backup_Frequency that
have values of none, daily, or weekly that correspond to the desired backup
frequency. An audit finds that developers are occasionally not tagging the
EBS volumes. A DevOps engineer needs to ensure that all EBS volumes
always have the Backup_Frequency tag so that the company can perform
backups at least weekly unless a different value is specified. Which solution
will meet these requirements? - B. Set up AWS Config in the account. Use
a managed rule that returns a compliance failure for EC2::Volume
resources that do not have a Backup Frequency tag applied. Configure a

remediation action that uses a custom AWS Systems Manager Automation
runbook to apply the Backup_Frequency tag with a value of weekly.
A company is using an Amazon Aurora cluster as the data store for its
application. The Aurora cluster is configured with a single DB instance. The
application performs read and write operations on the database by using
the cluster's instance endpoint. The company has scheduled an update to
be applied to the cluster during an upcoming maintenance window. The
cluster must remain available with the least possible interruption during the
maintenance window. What should a DevOps engineer do to meet these
requirements? - C. Turn on the Multi-AZ option on the Aurora cluster.
Update the application to use the Aurora cluster endpoint for write
operations. Update the Aurora cluster's reader endpoint for reads.
A company must encrypt all AMIs that the company shares across
accounts. A DevOps engineer has access to a source account where an
unencrypted custom AMI has been built. The DevOps engineer also has
access to a target account where an Amazon EC2 Auto Scaling group will
launch EC2 instances from the AMI. The DevOps engineer must share the
AMI with the target account. The company has created an AWS Key
Management Service (AWS KMS) key in the source account. Which
additional steps should the DevOps engineer perform to meet the
requirements? (Choose three.) - A. In the source account, copy the
unencrypted AMI to an encrypted AMI. Specify the KMS key in the copy
action.
C. In the source account, create a KMS grant that delegates permissions to
the Auto Scaling group service-linked role in the target account.
