Question No. 1

A company has migrated its application to AWS. The company will host the application on Amazon EC2 instances of multiple instance families.

During initial testing, a SysOps administrator identifies performance issues on selected EC2 instances. The company has a strict budget allocation policy, so the

SysOps administrator must use the right resource types with the performance characteristics to match the workload.

What should the SysOps administrator do to meet this requirement?

APurchase regional Reserved Instances (RIs) for immediate cost savings. Review and take action on the EC2 rightsizing recommendations in Cost Explorer. Exchange the RIs for the optimal instance family after rightsizing.

BPurchase zonal Reserved Instances (RIs) for the existing instances. Monitor the RI utilization in the AWS Billing and Cost Management console. Make adjustments to instance sizes to optimize utilization.

CReview and take action on AWS Compute Optimizer recommendations. Purchase Compute Savings Plans to reduce the cost that is required to run the compute resources. Most Voted

DReview resource utilization metrics in the AWS Cost and Usage Report. Rightsize the EC2 instances. Create On-Demand Capacity Reservations for the rightsized resources.

Show Answer

Correct Answer: C

When managing performance and cost for EC2 instances across different families, the following steps are recommended:

Utilize AWS Compute Optimizer: This service provides recommendations for EC2 instances based on historical usage patterns and existing configurations. It helps identify optimal EC2 instance types and sizes that could deliver better performance and cost savings for your specific workload.

Implement Compute Savings Plans: After determining the most suitable instance types and sizes through Compute Optimizer, purchasing Compute Savings Plans can offer significant cost savings. These savings plans apply to any instance family across any region, providing flexibility and cost efficiency without upfront commitment to specific instance types.

AWS Documentation Reference: Further details can be found in the AWS documentation on Compute Optimizer and Compute Savings Plans:

Question No. 2

A company has an application that is running on Amazon EC2 instances in a VPC. The application needs access to download software updates from the internet. The VPC has public subnets and private signets. The company's security policy requires all ECS instances to be deployed in private subnets

What should a SysOps administrator do to meet those requirements?

AAdd an internet gateway to the VPC In the route table for the private subnets, odd a route to the interne; gateway.

BAdd a NAT gateway to a private subnet. In the route table for the private subnets, add a route to the NAT gateway.

CAdd a NAT gateway to a public subnet in the route table for the private subnets, add a route to the NAT gateway.

DAdd two internet gateways to the VPC. In The route tablet for the private subnets and public subnets, add a route to each internet gateway.

Show Answer

Correct Answer: C

To ensure that EC2 instances in private subnets can access the internet for software updates while complying with the security policy that requires instances to be in private subnets, you should use a NAT gateway. A NAT gateway allows instances in private subnets to initiate outbound traffic to the internet but prevents the internet from initiating connections to those instances.

Steps:

Create a NAT Gateway:

Open the Amazon VPC console.

In the navigation pane, choose 'NAT Gateways'.

Choose 'Create NAT Gateway'.

Select the public subnet where you want to create the NAT gateway.

Choose an Elastic IP address for the NAT gateway.

Choose 'Create a NAT Gateway'.

Update the Route Table for Private Subnets:

Open the Amazon VPC console.

In the navigation pane, choose 'Route Tables'.

Select the route table associated with your private subnets.

Choose the 'Routes' tab and then 'Edit routes'.

Add a route with the destination 0.0.0.0/0 and the target as the NAT gateway ID.

Save the changes.

This setup ensures that instances in private subnets can access the internet via the NAT gateway in the public subnet.

Question No. 3

A company is using an Amazon CloudWatch alarm lo monitor the FreeLocalStorage metric for an Amazon Aurora PostgreSQL production database The alarm goes into ALARM state and indicates that the database is running low on temporary storage. A SysOps administrator discovers that a weekly report is using most of the temporary storage that is currently allocated.

What should the SysOps administrator do to solve this problem?

ATurn on Aurora PostgreSQL query plan management.

BModify the configuration of the DB cluster to turn on storage auto scaling.

CAdd an Aurora read replica to the DB cluster. Modify the report lo use the new read replica.

DModify the DB instance class for each DB instance In the DB cluster to increase the instance size.

Show Answer

Correct Answer: B

Storage Auto Scaling:

Aurora storage auto scaling automatically increases the storage capacity of the database cluster when free storage space is running low.

Steps:

Go to the AWS Management Console.

Navigate to RDS and select your Aurora DB cluster.

Modify the DB cluster configuration to enable storage auto scaling.

Apply the changes.

Question No. 4

A company uses an Amazon Simple Queue Service (Amazon SQS) standard queue with its application. The application sends messages to the queue with unique message bodies The company decides to switch to an SQS FIFO queue

What must the company do to migrate to an SQS FIFO queue?

ACreate a new SQS FIFO gueue Turn on content based deduplication on the new FIFO queue Update the application to include a message group ID in the messages

BCreate a new SQS FIFO queue Update the application to include the DelaySeconds parameter in the messages

CModify the queue type from SQS standard to SQS FIFO Turn off content-based deduplication on the queue Update the application to include a message group ID in the messages

DModify the queue type from SQS standard to SQS FIFO Update the application to send messages with identical message bodies and to include the DelaySeconds parameter in the messages

Show Answer

Correct Answer: A

FIFO queues don't support per-message delays, only per-queue delays. If your application sets the same value of the DelaySeconds parameter on each message, you must modify your application to remove the per-message delay and set DelaySeconds on the entire queue instead.

Question No. 5

A company runs an application on an Amazon EC2 instance A SysOps administrator creates an Auto Scaling group and an Application Load Balancer (ALB) to handle an increase in demand However, the EC2 instances are failing tie health check.

What should the SysOps administrator do to troubleshoot this issue?

AVerity that the Auto Scaling group is configured to use all AWS Regions.

BVerily that the application is running on the protocol and the port that the listens is expecting.

CVerify the listener priority in the ALB Change the priority if necessary.

DVerify the maximum number of instances in the Auto Scaling group Change the number if necessary

Show Answer

Correct Answer: B

When EC2 instances fail health checks from the Application Load Balancer (ALB), it's often due to a mismatch between what the ALB is checking for and what the application is providing. Ensuring that the application is correctly configured to respond on the expected protocol and port is crucial.

Steps:

Check ALB Health Check Configuration:

Open the Amazon EC2 console.

Navigate to the Load Balancers section.

Select your ALB and go to the 'Health Checks' tab.

Verify the protocol (HTTP/HTTPS) and port specified in the health check configuration.

Verify Application Configuration:

Ensure that the application on the EC2 instances is running and listening on the same protocol and port configured in the ALB health check.

Check firewall settings, security groups, and network ACLs to ensure that traffic is allowed on the specified port.

Test Connectivity:

Use tools like curl or telnet from another instance or from within the same instance to ensure the application responds correctly to health check requests.

Review Health Check Logs:

Look at the logs for the application and the ALB to identify any errors or misconfigurations.
