A SysOps administrator is responsible for a legacy. CPU-heavy application The application can only be scaled vertically Currently, the application is deployed on a single t2 large Amazon EC2 instance The system is showing 90% CPU usage and significant performance latency after a few minutes What change should be made to alleviate the performance problem?

• A.Upgrade to a compute-optimized instance
• B.Add additional 12 large instances to the application
• C.Purchase Reserved Instances
• D.Change the Amazon EBS volume to Provisioned lOPs

A company uses an Amazon Elastic File System (Amazon EFS) file system to share files across many Linux Amazon EC2 instances. A SysOps administrator notices that the file system's PercentIOLimit metric is consistently at 100% for 15 minutes or longer. The SysOps administrator also notices that the application that reads and writes to that file system is performing poorly. They application requires high throughput and IOPS while accessing the file system.
What should the SysOps administrator do to remediate the consistently high PercentIOLimit metric?

• A.Create a new EFS file system that uses Max I/O performance mode. Use AWS DataSync to migrate data to the new EFS file system.
• B.Create an EFS lifecycle policy to transition future files to the Infrequent Access (IA) storage class to improve performance. Use AWS DataSync to migrate existing data to IA storage.
• C.Modify the existing EFS file system and activate Max I/O performance mode.
• D.Modify the existing EFS file system and activate Provisioned Throughput mode.

A company is running a serverless application on AWS Lambda. The application stores data in an Amazon RDS for MySQL DB instance. Usage has steadily increased, and recently there have been numerous "too many connections" errors when the Lambda function attempts to connect to the database. The company already has configured the database to use the maximum max_connections value that is possible.
What should a SysOps administrator do to resolve these errors?

• A.Increase the value in the max_connect_errors parameter in the parameter group that the database uses.
• B.Update the Lambda function's reserved concurrency to a higher value.
• C.Use Amazon RDS Proxy to create a proxy. Update the connection string in the Lambda function.
• D.Create a read replica of the database. Use Amazon Route 53 to create a weighted DNS record that contains both databases.

A company needs to create a daily Amazon Machine Image (AMI) of an existing Amazon Linux EC2 instance that hosts the operating system, application, and database on multiple attached Amazon Elastic Block Store (Amazon EBS) volumes. File system integrity must be maintained.
Which solution will meet these requirements?

• A.Create an AWS Lambda function to call the CreateImage API operation with the EC2 instance ID and the no-reboot parameter enabled. Create a daily scheduled Amazon EventBridge (Amazon CloudWatch Events) rule that invokes the function.
• B.Create an AWS Lambda function to call the CreateImage API operation with the EC2 instance ID and the reboot parameter enabled. Create a daily scheduled Amazon EventBridge (Amazon CloudWatch Events) rule that invokes the function.
• C.Use AWS Backup to create a backup plan with a backup rule that runs daily. Assign the resource ID of the EC2 instance with the no-reboot parameter enabled.
• D.Use AWS Backup to create a backup plan with a backup rule that runs daily. Assign the resource ID of the EC2 instance with the reboot parameter enabled.

A large company is using AWS Organizations to manage its multi-account AWS environment. According to company policy, all users should have read-level access to a particular Amazon S3 bucket in a central account. The S3 bucket data should not be available outside the organization. A SysOps administrator must set up the permissions and add a bucket policy to the S3 bucket.
Which parameters should be specified to accomplish this in the MOST efficient manner?

• A.Specify the organization's management account as the principal.
• B.Specify PrincipalOrgld as the principal.
• C.Specify all account numbers as the principal.
• D.Specify '*' as the principal and PrincipalOrgld as a condition.
