Amazon AWS Certified SysOps Administrator - Associate (SOA-C02) Sample Questions (Q93-Q98):

NEW QUESTION # 93
A company is testing Amazon Elasticsearch Service (Amazon ES) as a solution for analyzing system logs from a fleet of Amazon EC2 instances. During the test phase, the domain operates on a single-node cluster. A SysOps administrator needs to transition the test domain into a highly available production-grade deployment.
Which Amazon ES configuration should the SysOps administrator use to meet this requirement?

  • A. Use a cluster of eight data nodes across two Availability Zones. Deploy four master nodes in a failover AWS Region.
  • B. Use a cluster of six data nodes across three Availability Zones. Use three dedicated master nodes.
  • C. Use a cluster of four data nodes across two AWS Regions. Deploy four dedicated master nodes in each Region.
  • D. Use a cluster of six data nodes across three Availability Zones. Use six dedicated master nodes.

Answer: B


NEW QUESTION # 94
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. Create a read replica of the database Use Amazon Route 53 to create a weighted DNS record that contains both databases
  • B. Use Amazon RDS Proxy to create a proxy Update the connection string in the Lambda function
  • C. Increase the value in the max_connect_errors parameter in the parameter group that the database uses
  • D. Update the Lambda function's reserved concurrency to a higher value

Answer: B

Explanation:
https://aws.amazon.com/blogs/compute/using-amazon-rds-proxy-with-aws-lambda/ RDS Proxy acts as an intermediary between your application and an RDS database. RDS Proxy establishes and manages the necessary connection pools to your database so that your application creates fewer database connections. Your Lambda functions interact with RDS Proxy instead of your database instance. It handles the connection pooling necessary for scaling many simultaneous connections created by concurrent Lambda functions. This allows your Lambda applications to reuse existing connections, rather than creating new connections for every function invocation.
Check "Database proxy for Amazon RDS" section in the link to see how RDS proxy help Lambda handle huge connections to RDS MySQL https://aws.amazon.com/blogs/compute/using-amazon-rds-proxy-with-aws-lambda/


NEW QUESTION # 95
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. 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.
  • C. 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.
  • 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 no-reboot parameter enabled.

Answer: C

Explanation:
Reference:
https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/Creating_EBSbacked_WinAMI.html
"NoReboot By default, Amazon EC2 attempts to shut down and reboot the instance before creating the image. If the No Reboot option is set, Amazon EC2 doesn't shut down the instance before creating the image. When this option is used, file system integrity on the created image can't be guaranteed." Besides, we can use AWS EventBridge to invoke Lambda function https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateImage.html


NEW QUESTION # 96
A company uses Amazon Elasticsearch Service (Amazon ES) to analyze sales and customer usage dat a. Members of the company's geographically dispersed sales team are traveling. They need to log in to Kibana by using their existing corporate credentials that are stored in Active Directory. The company has deployed Active Directory Federation Services (AD FS) to enable authentication to cloud services.
Which solution will meet these requirements?

  • A. Enable Active Directory user authentication in Kibana. Create an IP-based custom domain access policy in Amazon ES that includes the Active Directory server's IP address.
  • B. Configure Active Directory as an authentication provider in Amazon ES. Add the Active Directory server's domain name to Amazon ES. Configure Kibana to use Amazon ES authentication.
  • C. Deploy an Amazon Cognito user pool. Configure Active Directory as an external identity provider for the user pool. Enable Amazon Cognito authentication for Kibana on Amazon ES.
  • D. Establish a trust relationship with Kibana on the Active Directory server. Enable Active Directory user authentication in Kibana. Add the Active Directory server's IP address to Kibana.

Answer: C
