A company uses Amazon RDS for Microsoft SQL Server as its primary database for applications. The company needs to ensure high availability within and across AWS Regions.

An Amazon Route 53 CNAME record is configured for the database endpoint. The applications connect to the database endpoint. The company must redirect application traffic to a standby database during a failover event. The company must maintain an RPO of less than 1 minute and an RTO of less than 10 minutes .

Which solution will meet these requirements?

Options:

A.

Deploy an Amazon RDS for SQL Server Multi-AZ DB cluster deployment that uses cross-Region read replicas . Use automation to promote the read replica to a standalone instance and to update the Route 53 record.

B.

Deploy an Amazon RDS for SQL Server Multi-AZ DB cluster deployment. Set up automated snapshots to be copied to another Region every 5 minutes. Use AWS Lambda to restore the latest snapshot in the secondary Region during failover.

C.

Deploy an Amazon RDS for SQL Server Single-AZ DB instance . Use AWS Database Migration Service (AWS DMS) to replicate data continuously to an RDS DB instance in another Region. Use Amazon CloudWatch alarms to notify the company about failover events.

Question 2

A company has proprietary data available by using an Amazon CloudFront distribution. The company needs to ensure that the distribution is accessible by only users from the corporate office that have a known set of IP address ranges. An AWS WAF web ACL is associated with the distribution and has a default action set to Count.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

A.

Create a new regex pattern set. Add the regex pattern set to a new rule group. Create a new web ACL that has a default action set to Block. Associate the web ACL with the CloudFront distribution. Add a rule that allows traffic based on the new rule group.

B.

Create an AWS WAF IP address set that matches the corporate office IP address range. Create a new web ACL that has a default action set to Allow. Associate the web ACL with the CloudFront distribution. Add a rule that allows traffic from the IP address set.

C.

Create a new regex pattern set. Add the regex pattern set to a new rule group. Set the default action on the existing web ACL to Allow. Add a rule that has priority 0 that allows traffic based on the regex pattern set.

D.

Create a WAF IP address set that matches the corporate office IP address range. Set the default action on the existing web ACL to Block. Add a rule that has priority 0 that allows traffic from the IP address set.

Question 3

A company has developed an AWS Lambda function that handles orders received through an API. The company is using AWS CodeDeploy to deploy the Lambda function as the final stage of a CI/CD pipeline.

A DevOps engineer has noticed there are intermittent failures of the ordering API for a few seconds after deployment. After some investigation the DevOps engineer believes the failures are due to database changes not having fully propagated before the Lambda function is invoked

How should the DevOps engineer overcome this?

Options:

A.

Add a BeforeAllowTraffic hook to the AppSpec file that tests and waits for any necessary database changes before traffic can flow to the new version of the Lambda function.

B.

Add an AfterAlIowTraffic hook to the AppSpec file that forces traffic to wait for any pending database changes before allowing the new version of the Lambda function to respond.

C.

Add a BeforeAllowTraffic hook to the AppSpec file that tests and waits for any necessary database changes before deploying the new version of the Lambda function.

D.

Add a validateService hook to the AppSpec file that inspects incoming traffic and rejects the payload if dependent services such as the database are not yet ready.
