PDF with 477 Questions

A company has a web application with a database tier that consists of an Amazon EC2 instance that runs MySQL. A SysOps administrator needs to minimize potential data loss and the time that is required to recover in the event of a database failure.
What is the MOST operationally efficient solution that meets these requirements?

  1. Create an Amazon CloudWatch alarm for the StatusCheckFailed_System metric to invoke an AWS Lambda function that stops and starts the EC2 instance.
  2. Create an Amazon RDS for MySQL Multi-AZ DB instance. Use a MySQL native backup that is stored in Amazon S3 to restore the data to the new database. Update the connection string in the web application.
  3. Create an Amazon RDS for MySQL Single-AZ DB instance with a read replica. Use a MySQL native backup that is stored in Amazon S3 to restore the data to the new database. Update the connection string in the web application
  4. Use Amazon Data Lifecycle Manager (Amazon DLM) to take a snapshot of the Amazon Elastic Block Store (Amazon EBS) volume every hour. In the event of an EC2 instance failure, restore the EBS volume from a snapshot.

Answer(s): B



A developer creates an AWS Lambda function that runs when an object is put into an Amazon S3 bucket. The function reformats the object and places the object back into the S3 bucket. During testing, the developer notices a recursive invocation loop. The developer asks a SysOps administrator to immediately stop the recursive invocations.
What should the SysOps administrator do to stop the loop without errors?

  1. Delete all the objects from the S3 bucket.
  2. Set the function’s reserved concurrency to 0.
  3. Update the S3 bucket policy to deny access for the function.
  4. Publish a new version of the function.

Answer(s): B



A company has a public web application that experiences rapid traffic increases after advertisements appear on local television. The application runs on Amazon EC2 instances that are in an Auto Scaling group. The Auto Scaling group is not keeping up with the traffic surges after an advertisement runs. The company often needs to scale out to 100 EC2 instances during the traffic surges.
The instance startup times are lengthy because of a boot process that creates machine-specific data caches that are unique to each instance. The exact timing of when the advertisements will appear on television is not known. A SysOps administrator must implement a solution so that the application can function properly during the traffic surges.
Which solution will meet these requirements?

  1. Create e warm pool. Keep enough instances in the Stopped state to meet the increased demand.
  2. Start 100 instances. Allow the boot process to finish running. Store this data on the instance store volume before stopping the instances.
  3. Increase the value of the instance warmup time in the scaling policy
  4. Use predictive scaling for the Auto Scaling group.

Answer(s): A



A SysOps administrator manages the caching of an Amazon CloudFront distribution that serves pages of a website, The SysOps administrator needs to configure the distribution so that the TTL of individual pages can vary. The TTL of the individual pages must remain within the maximum TLL and the minimum TTL that are set for the distribution.
Which solution will meet these requirements?

  1. Create an AWS Lambda function that calls the Createlnvalidation API operation when a change in cache time is necessary.
  2. Add a Cache-Control: max-age directive to the object at the origin when content is being returned to CloudFront.
  3. Add a no-cache header through a Lambda@Edge function in response to the Viewer response.
  4. Add.an Expires header through a CloudFront function in response to the Viewer response.

Answer(s): B



A company has deployed an application on Amazon EC2 instances in a single VPC. The company has placed the EC2 instances in a private subnet in the VPC.
The EC2 instances need access to Amazon S3 buckets that are in the same AWS Region as the EC2 instances. A SysOps administrator must provide the EC2 instances with access to the S3 buckets without requiring any changes to the EC2 instances or the application. The EC2 instances must not have access to the internet.
Which solution will meet these requirements?

  1. Create an S3 gateway endpoint that uses the default gateway endpoint policy. Associate the private subnet with the gateway endpoint.
  2. Create an S3 interface endpoint. Associate the EC2 instances with the interface endpoint.
  3. Configure a NAT gateway. Associate the private subnet with the NAT gateway.
  4. Configure a proxy EC2 instance. Update the private subnet route tables to route traffic through the proxy EC2 instance. Configure the proxy to route all S3 requests to the target S3 bucket.
