Question 12

An application uses an Amazon EC2 Auto Scaling group. A developer notices that EC2 instances are taking a long time to become available during scale-out events. The UserData script is taking a long time to run.

The developer must implement a solution to decrease the time that elapses before an EC2 instance becomes available. The solution must make the most recent version of the application available at all times and must apply all available security updates. The solution also must minimize the number of images that are created. The images must be validated.

Which combination of steps should the developer take to meet these requirements? (Choose two.)

Options:

Use EC2 Image Builder to create an Amazon Machine Image (AMI). Install all the patches and agents that are needed to manage and run the application. Update the Auto Scaling group launch configuration to use the AMI.

Use EC2 Image Builder to create an Amazon Machine Image (AMI). Install the latest version of the application and all the patches and agents that are needed to manage and run the application. Update the Auto Scaling group launch configuration to use the AMI.

Set up AWS CodeDeploy to deploy the most recent version of the application at runtime.

Set up AWS CodePipeline to deploy the most recent version of the application at runtime.

Remove any commands that perform operating system patching from the UserData script.

Honey

I highly recommend it. They made a big difference for me and I'm sure they'll help you too. Just make sure to use them wisely and not solely rely on them. They should be used as a supplement to your regular studies.

Antoni (not set)

Good point. Thanks for the advice. I'll definitely keep that in mind.

Reeva

Wow what a success I achieved today. Thank you so much Cramkey for amazing Dumps. All students must try it.

Amari (not set)

Wow, that's impressive. I'll definitely keep Cramkey in mind for my next exam.

Rosalie

I passed. I would like to tell all students that they should definitely give Cramkey Dumps a try.

Maja (not set)

That sounds great. I'll definitely check them out. Thanks for the suggestion!

Neve

Will I be able to achieve success after using these dumps?

Rohan (not set)

Absolutely. It's a great way to increase your chances of success.

Cecilia

Yes, I passed my certification exam using Cramkey Dumps.

Helena (not set)

Great. Yes they are really effective

Question 13

A company has deployed infrastructure on AWS. A development team wants to create an AWS Lambda function that will retrieve data from an Amazon Aurora database. The Amazon Aurora database is in a private subnet in company's VPC. The VPC is named VPC1. The data is relational in nature. The Lambda function needs to access the data securely.

Which solution will meet these requirements?

Options:

Create the Lambda function. Configure VPC1 access for the function. Attach a security group named SG1 to both the Lambda function and the database. Configure the security group inbound and outbound rules to allow TCP traffic on Port 3306.

Create and launch a Lambda function in a new public subnet that is in a new VPC named VPC2. Create a peering connection between VPC1 and VPC2.

Create the Lambda function. Configure VPC1 access for the function. Assign a security group named SG1 to the Lambda function. Assign a second security group named SG2 to the database. Add an inbound rule to SG1 to allow TCP traffic from Port 3306.

Export the data from the Aurora database to Amazon S3. Create and launch a Lambda function in VPC1. Configure the Lambda function query the data from Amazon S3.

Question 14

A developer is testing an application that invokes an AWS Lambda function asynchronously. During the testing phase the Lambda function fails to process after two retries.

How can the developer troubleshoot the failure?

Options:

Configure AWS CloudTrail logging to investigate the invocation failures.

Configure Dead Letter Queues by sending events to Amazon SQS for investigation.

Configure Amazon Simple Workflow Service to process any direct unprocessed events.

Configure AWS Config to process any direct unprocessed events.

Question 15

A developer is building a new application on AWS. The application uses an AWS Lambda function that retrieves information from an Amazon DynamoDB table. The developer hard coded the DynamoDB table name into the Lambda function code. The table name might change over time. The developer does not want to modify the Lambda code if the table name changes.

Which solution will meet these requirements MOST efficiently?

Options:

Create a Lambda environment variable to store the table name. Use the standard method for the programming language to retrieve the variable.

Store the table name in a file. Store the file in the /tmp folder. Use the SDK for the programming language to retrieve the table name.

Create a file to store the table name. Zip the file and upload the file to the Lambda layer. Use the SDK for the programming language to retrieve the table name.

Create a global variable that is outside the handler in the Lambda function to store the table name.
