An engineering firm has launched Amazon EC2 Instance in us-east-1 & us-west-1. Metric collection is done using the CloudWatch Agent configuration file. The operations team requires all the metrics for these instances to be sent to a central location in the us-west-1 region.
What setting needs to be done with the CloudWatch Agent configuration file?

Answer options:

A.Specify region as us-west-1 in the region field of the CWAgent section of the CloudWatch agent configuration file.
B.Specify region as us-west-1 in the region field of logs section of the CloudWatch agent configuration file.
C.Specify region as us-west-1 in the region field of the agent section of the CloudWatch agent configuration file.
D.Specify region as us-west-1 in the region field of the metric section of the CloudWatch agent configuration file.

Correct Answer: C
Amazon CloudWatch agent configuration file consists of three sections.
Agent:This section consists of fields for configuration settings of the agent like metric frequency, region to which metric needs to be sent.
Metric: Metric section specifies custom metric to be collected.
Logs: Logs section specifies the log file which needs to be published to CloudWatch Logs.
Option A is incorrect as CWAgent is an invalid option with the CloudWatch Agent configuration file.
Options B & D is incorrect as the region field is part of the agent section & not part of the logs or metric section.
