AWS Certified Solutions Architect - Associate (SAA-C03) Questions and Answers

Question 57

A media company runs an application on multiple Amazon EC2 instances that requires high storage input/output operations per second (IOPS).

To achieve the necessary performance, a solutions architect wants to stripe multiple Amazon EBS volumes together and attach the volumes to EC2 instances. The solutions architect wants to receive a notification when IOPS are over-provisioned.

Which solution will meet these requirements?

Options:

Configure auto scaling for the EBS volumes to automatically increase or decrease IOPS based on the EC2 instance CPU utilization metric.

Deploy the application on an EC2 instance type that supports the highest possible IOPS.

Create a custom AWS Config rule to monitor the provisioned IOPS for the EBS volumes that are attached to the EC2 instances and to send notifications.

Adjust the IOPS of each EBS volume daily based on Amazon CloudWatch metrics for IOPS utilization.

Question 58

A company is planning to run an AI/ML workload on AWS. The company needs to train a model on a dataset that is in Amazon S3 Standard. A model training application requires multiple compute nodes and single-digit millisecond access to the data.

Which solution will meet these requirements in the MOST cost-effective way?

Options:

Move the data to S3 Intelligent-Tiering. Point the model training application to S3 Intelligent-Tiering as the data source.

Add partitions to the S3 bucket by adding random prefixes. Reconfigure the model training application to point to the new prefixes as the data source.

Move the data to S3 Express One Zone. Point the model training application to S3 Express One Zone as the data source.

Move the data to a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS)volume attached to an Amazon EC2 instance. Point the model training application to the gp3 volume as the data source.

Question 59

A company is migrating some of its applications to AWS. The company wants to migrate and modernize the applications quickly after it finalizes networking and security strategies. The company has set up an AWS Direct Connect connection in a central network account.

The company expects to have hundreds of AWS accounts and VPCs in the near future. The corporate network must be able to access the resources on AWS seamlessly and also must be able to communicate with all the VPCs. The company also wants to route its cloud resources to the internet through its on-premises data center.

Which combination of steps will meet these requirements? (Select THREE.)

Options:

Create a Direct Connect gateway in the central account. In each of the accounts, create an association proposal by using the Direct Connect gateway and the account ID for every virtual private gateway.

Create a Direct Connect gateway and a transit gateway in the central network account. Attach the transit gateway to the Direct Connect gateway by using a transit VIF.

Provision an internet gateway. Attach the internet gateway to subnets. Allow internet traffic through the gateway.

Share the transit gateway with other accounts. Attach VPCs to the transit gateway.

Provision VPC peering as necessary.

Provision only private subnets. Open the necessary route on the transit gateway and customer gateway to allow outbound internet traffic from AWS to flow through NAT services that run in the data center.

Answer:

B, D, F

Explanation:

For a large-scale multi-account AWS environment with many VPCs and centralized Direct Connect, AWS recommends using a Transit Gateway (TGW) architecture combined with a Direct Connect gateway (DXGW). This setup allows scalable, centralized connectivity between on-premises and multiple VPCs across accounts.

Step B: Creating a Direct Connect gateway and Transit Gateway in a central network account and connecting them via a transit VIF enables the on-premises network to access all connected VPCs.

Step D: Sharing the transit gateway with other accounts via AWS Resource Access Manager (RAM) allows the central TGW to attach VPCs in multiple accounts, simplifying multi-account connectivity.

Step F: To route cloud resources’ internet traffic back through the on-premises data center (for centralized egress), provisioning only private subnets and routing outbound internet traffic through NAT or firewall services in the data center is necessary. This requires configuring transit gateway and customer gateway routes appropriately.

Option A is partially correct in the use of Direct Connect gateway but association proposals are not scalable for hundreds of VPCs and accounts compared to transit gateway. Option C (internet gateway) is irrelevant here as traffic egress is required via on-premises data center, not directly to the internet. Option E (VPC peering) is not scalable for hundreds of VPCs.

Question 60

A company wants to use automatic machine learning (ML) to create and visualize forecasts of complex scenarios and trends.

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

Options:

Use an AWS Glue ML job to transform the data and create forecasts. Use Amazon QuickSight to visualize the data.

Use Amazon QuickSight to visualize the data. Use ML-powered forecasting in QuickSight to create forecasts.

Use a prebuilt ML AMI from the AWS Marketplace to create forecasts. Use Amazon QuickSight to visualize the data.

Use Amazon SageMaker AI inference pipelines to create and update forecasts. Use Amazon QuickSight to visualize the combined data.
