Amazon SAP-C01 Practice Test - Questions Answers, Page 30

A company has a serverless application comprised of Amazon CloudFront, Amazon API Gateway, and AWS Lambda functions. The current deployment process of the application code is to create a new version number of the Lambda function and run an AWS CLI script to update. If the new function version has errors, another CLI script reverts by deploying the previous working version of the function. The company would like to decrease the time to deploy new versions of the application logic provided by the Lambda functions, and also reduce the time to detect and revert when errors are identified. How can this be accomplished?

With respect to AWS Lambda permissions model, at the time you create a Lambda function, you specify an IAM role that AWS Lambda can assume to execute your Lambda function on your behalf. This role is also referred to as the________role.

By default, what is the maximum number of Cache Nodes you can run in Amazon ElastiCache?

A company experienced a breach of highly confidential personal information due to permission issues on an Amazon S3 bucket. The Information Security team has tightened the bucket policy to restrict access. Additionally, to be better prepared for future attacks, these requirements must be met:

Identify remote IP addresses that are accessing the bucket objects.

Receive alerts when the security policy on the bucket is changed. Remediate the policy changes automatically. Which strategies should the Solutions Architect use?

A company uses an Amazon EMR cluster to process data once a day. The raw data comes from Amazon S3, and the resulting processed data is also stored in Amazon S3. The processing must complete within 4 hours; currently, it only takes 3 hours. However, the processing time is taking 5 to 10 minutes longer each week due to an increasing volume of raw data. The team is also concerned about rising costs as the compute capacity increases. The EMR cluster is currently running on three m3.xlarge instances (one master and two core nodes). Which of the following solutions will reduce costs related to the increasing compute needs?

A company is migrating its three-tier web application from on-premises to the AWS Cloud. The company has the following requirements for the migration process:

Ingest machine images from the on-premises environment.

Synchronize changes from the on-premises environment to the AWS environment until the production cutover. Minimize downtime when executing the production cutover.

Migrate the virtual machines’ root volumes and data volumes.

Which solution will satisfy these requirements with minimal operational overhead?

In Amazon ElastiCache, the failure of a single cache node can have an impact on the availability of your application and the load on your back-end database while ElastiCache provisions a replacement for the failed cache node and it get repopulated.

Which of the following is a solution to reduce this potential availability impact?

Identify an application that polls AWS Data Pipeline for tasks and then performs those tasks.

A retail company runs a business-critical web service on an Amazon Elastic Container Service (Amazon ECS) cluster that runs on Amazon EC2 instances. The web service receives POST requests from end users and writes data to a MySQL database that runs on a separate EC2 instance. The company needs to ensure that data loss does not occur.

The current code deployment process includes manual updates of the ECS service. During a recent deployment, end users encountered intermittent 502 Bad Gateway errors in response to valid web requests.

The company wants to implement a reliable solution to prevent this issue from recurring. The company also wants to automate code deployments. The solution must be highly available and must optimize cost-effectiveness.

Which combination of steps will meet these requirements? (Choose three.)
