AWS Certified Solutions Architect - Professional Questions and Answers

Question 57

A telecommunications company is running an application on AWS. The company has set up an AWS Direct Connect connection between the company ' s on-premises data center and AWS. The company deployed the application on Amazon EC2 instances in multiple Availability Zones behind an internal Application Load Balancer (ALB). The company ' s clients connect from the on-premises network by using HTTPS. The TLS terminates in the ALB. The company has multiple target groups and uses path-based routing to forward requests based on the URL path.

The company is planning to deploy an on-premises firewall appliance with an allow list that is based on IP address. A solutions architect must develop a solution to allow traffic flow to AWS from the on-premises network so that the clients can continue to access the application.

Which solution will meet these requirements?

Options:

A.

Configure the existing ALB to use static IP addresses. Assign IP addresses in multiple Availability Zones to the ALB. Add the ALB IP addresses to the firewall appliance.

B.

Create a Network Load Balancer (NLB). Associate the NLB with one static IP addresses in multiple Availability Zones. Create an ALB-type target group for the NLB and add the existing ALAdd the NLB IP addresses to the firewall appliance. Update the clients to connect to the NLB.

C.

Create a Network Load Balancer (NLB). Associate the LNB with one static IP addresses in multiple Availability Zones. Add the existing target groups to the NLB. Update the clients to connect to the NLB. Delete the ALB Add the NLB IP addresses to the firewall appliance.

D.

Create a Gateway Load Balancer (GWLB). Assign static IP addresses to the GWLB in multiple Availability Zones. Create an ALB-type target group for the GWLB and add the existing ALB. Add the GWLB IP addresses to the firewall appliance. Update the clients to connect to the GWLB.

Question 58

Question:

How should a companyefficiently processinfrequently uploaded S3 data using a long-running (up to 25 minutes) custom application?

Options:

A.

ECS on Fargate triggered by EventBridge

B.

Lambda in Step Functions with 30-min timeout

C.

ECS with EC2 and Glue crawler

D.

Lambda triggered by fan-out HTTP EventBridge logic

Question 59

A solutions architect needs to migrate an on-premises legacy application to AWS. The application runs on two servers behind a bad balancer. The application requires a license file that is associated with the MAC address of the server ' s network adapter. It takes the software vendor 12 hours to send new license files. The application also uses configuration files with a static IP address to access a database host names are not supported.

Given these requirements. which combination of steps should be taken to implement highly available architecture for the application servers in AWS? (Select TWO.)

Options:

A.

Create a pool of ENIs. Request license files from the vendor for the pool, and store the license files in Amazon $3. Create a bootstrap automation script to download a license file and attach the corresponding ENI to anAmazon EC2 instance.

B.

Create a pool of ENIs. Request license files from the vendor for the pool, store the license files on an Amazon EC2 instance. Create an AMI from the instance and use this AMI for all future EC2

C.

Create a bootstrap automation script to request a new license file from the vendor. When the response is received, apply the license file to an Amazon EC2 instance.

D.

Edit the bootstrap automation script to read the database server IP address from the AWS Systems Manager Parameter Store. and inject the value into the local configuration files.

E.

Edit an Amazon EC2 instance to include the database server IP address in the configuration files and re-create the AMI to use for all future EC2 instances.

Question 60

A company collects air quality data from sensors. The company plans to use the MQTT protocol to send the data to AWS IoT Core. The company will process the data and then will store the data in an Amazon Aurora database.

During periods of low air quality, sensors will send data more frequently. The company must buffer the data during these periods to make sure that no data is lost before the data is processed and stored.

Which solution will meet these requirements?

Options:

A.

Create an Amazon Kinesis data stream. Create an AWS IoT rule action and set the data stream as the target. Create an AWS Step Functions state machine that is invoked by the data stream. Use the state machine to process and store the data.

B.

Create an Amazon Kinesis data stream. Create an AWS IoT rule action and set the data stream as the target. Create an application that runs on an Amazon ECS cluster with the AWS Fargate launch type. Configure the application to read data from the data stream, process the data, and store the data.

C.

Create an Amazon SQS queue. Create an AWS IoT rule action and set the SQS queue as the target. Create an AWS Step Functions state machine that is invoked by the SQS queue. Use the state machine to process and store the data.

D.

Create an Amazon SNS topic. Create an AWS IoT rule action and set the SNS topic as the target. Create an application that runs on an Amazon ECS cluster with the AWS Fargate launch type. Configure the application to read data from the SNS topic, process the data, and store the data.
