A company runs hundreds of Amazon EC2 instances in a single AWS Region. Each EC2 instance has two attached 1 GiB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volumes. A critical workload is using all the available IOPS capacity on the EBS volumes.
According to company policy, the company cannot change instance types or EBS volume types without completing lengthy acceptance tests to validate that the company’s applications will function properly. A SysOps administrator needs to increase the I/O performance of the EBS volumes as quickly as possible.
Which action should the SysOps administrator take to meet these requirements?

1. A. Increase the size of the 1 GiB EBS volumes.
2. B. Add two additional elastic network interfaces on each EC2 instance.
3. C. Turn on Transfer Acceleration on the EBS volumes in the Region.
4. D. Add all the EC2 instances to a cluster placement group.

Correct Answer: A
Increasing the size of the 1 GiB EBS volumes will increase the IOPS capacity of the volumes, which will improve the I/O performance of the EBS volumes. This option does not require any changes to the instance types or EBS volume types, so it can be done quickly without the need for lengthy acceptance tests to validate that the company's applications will function properly.

A Sysops administrator has created an Amazon EC2 instance using an AWS CloudFormation template in the us-east-I Region. The administrator finds that this
template has failed to create an EC2 instance in the us-west-2 Region. What is one cause for this failure?

1. A. Resource tags defined in the CloudFormation template are specific to the us-east-I Region.
2. B. The Amazon Machine Image (AMI) ID referenced in the CloudFormation template could not be found in the us-west-2 Region.
3. C. The cfn-init script did not run during resource provisioning in the us-west-2 Region.
4. D. The IAM user was not created in the specified Region.

Correct Answer: B
One possible cause for the failure of the CloudFormation template to create an EC2 instance in the us-west-2 Region is that the Amazon Machine Image (AMI) ID referenced in the template could not be found in the us-west-2 Region. This could be due to the fact that the AMI is not available in that region, or the credentials used to access the AMI were not configured properly. The other options (resource tags defined in the CloudFormation template are specific to the us-east-I Region, the cfn-init script did not run during resource provisioning in the us-west-2 Region, and the IAM user was not created in the specified Region) are not valid causes for this failure.

A company has a critical serverless application that uses multiple AWS Lambda functions. Each Lambda function generates 1 GB of log data daily in its own Amazon CloudWatch Logs log group. The company's security team asks for a count of application errors, grouped by type, across all of the log groups.
What should a SysOps administrator do to meet this requirement?

1. A. Perform a CloudWatch Logs Insights query that uses the stats command and count function.
2. B. Perform a CloudWatch Logs search that uses the groupby keyword and count function.
3. C. Perform an Amazon Athena query that uses the SELECT and GROUP BY keywords.
4. D. Perform an Amazon RDS query that uses the SELECT and GROUP BY keywords.

Correct Answer: A
