Question 68

A large financial services company uses Amazon ElastiCache (Redis OSS) for its new application that has a global user base. A solutions architect must develop a caching solution that will be available across AWS Regions and include low-latency replication and failover capabilities for disaster recovery (DR). The company's security team requires the encryption of cross-Region data transfers.

Which solution meets these requirements with the LEAST amount of operational effort?

Options:

Enable cluster mode in ElastiCache (Redis OSS). Then create multiple clusters across Regions and replicate the cache data by using AWS Database Migration Service (AWS DMS). Promote a cluster in the failover Region to handle production traffic when DR is required.

Create a global data store in ElastiCache (Redis OSS). Then create replica clusters in two other Regions. Promote one of the replica clusters as primary when DR is required.

Disable cluster mode in ElastiCache (Redis OSS). Then create multiple replication groups across Regions and replicate the cache data by using AWS Database Migration Service (AWS DMS). Promote a replication group in the failover Region to primary when DR is required.

Create a snapshot of ElastiCache (Redis OSS) in the primary Region and copy it to the failover Region. Use the snapshot to restore the cluster from the failover Region when DR is required.

Question 69

A company has a website that handles dynamic traffic loads. The website architecture is based on Amazon EC2 instances in an Auto Scaling group that is configured to use scheduled scaling. Each EC2 instance runs code from an Amazon Elastic File System (Amazon EFS) volume and stores shared data back to the same volume.

The company wants to optimize costs for the website.

Which solution will meet this requirement?

Options:

Reconfigure the Auto Scaling group to set a desired number of instances. Turn off scheduled scaling.

Create a new launch template version for the Auto Scaling group that uses larger EC2 instances.

Reconfigure the Auto Scaling group to use a target tracking scaling policy.

Replace the EFS volume with instance store volumes.

I used these dumps for my recent certification exam and I can say with certainty that they're absolutely valid dumps. The questions were very similar to what came up in the actual exam.

Really? That's great to hear! I used Cramkey Dumps too and I had the same experience. The questions were almost identical.

Question 70

A company runs an application on EC2 instances that need access to RDS credentials stored in AWS Secrets Manager.

Which solution meets this requirement?

Options:

Create an IAM role, and attach the role to each EC2 instance profile. Use an identity-based policy to grant the role access to the secret.

Create an IAM user, and attach the user to each EC2 instance profile. Use a resource-based policy to grant the user access to the secret.

Create a resource-based policy for the secret. Use EC2 Instance Connect to access the secret.

Create an identity-based policy for the secret. Grant direct access to the EC2 instances.

Question 71

A company has a social media application that is experiencing rapid user growth. The current architecture uses t-family Amazon EC2 instances. The current architecture struggles to handle the increasing number of user posts and images. The application experiences performance slowdowns during peak usage times.

A solutions architect needs to design an updated architecture that will resolve the performance issues and scale as usage increases.

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

Options:

Use the largest Amazon EC2 instance in the same family to host the application. Install a relational database on the instance to store all account information and to store posts and images.

Use Amazon Simple Queue Service (Amazon SQS) to buffer incoming posts. Use a larger EC2 instance in the same family to host the application. Store account information in Amazon DynamoDB. Store posts and images in the local EC2 instance file system.

Use an Amazon API Gateway REST API and AWS Lambda functions to process requests. Store account information in Amazon DynamoDB. Use Amazon S3 to store posts and images.

Deploy multiple EC2 instances in the same family. Use an Application Load Balancer to distribute traffic. Use a shared file system to store account information and to store posts and images.
