Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q467-Q472):

NEW QUESTION # 467
A company is migrating an application from on-premises servers to Amazon EC2 instances. As part of the migration design requirements, a solutions architect must implement infrastructure metric alarms. The company does not need to take action if CPU utilization increases to more than 50% for a short burst of time. However, if the CPU utilization increases to more than 50% and read IOPS on the disk are high at the same time, the company needs to act as soon as possible. The solutions architect also must reduce false alarms.
What should the solutions architect do to meet these requirements?

A. Create Amazon CloudWatch composite alarms where possible.
B. Create single Amazon CloudWatch metric alarms with multiple metric thresholds where possible.
C. Create Amazon CloudWatch dashboards to visualize the metrics and react to issues quickly.
D. Create Amazon CloudWatch Synthetics canaries to monitor the application and raise an alarm.

Answer: A

Explanation:
Composite alarms determine their states by monitoring the states of other alarms. You can **use composite alarms to reduce alarm noise**. For example, you can create a composite alarm where the underlying metric alarms go into ALARM when they meet specific conditions. You then can set up your composite alarm to go into ALARM and send you notifications when the underlying metric alarms go into ALARM by configuring the underlying metric alarms never to take actions. Currently, composite alarms can take the following actions: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Create_Composite_Alarm.html

NEW QUESTION # 468
A company runs a production application on a fleet of Amazon EC2 instances. The application reads the data from an Amazon SQS queue and processes the messages in parallel. The message volume is unpredictable and often has intermittent traffic. This application should continually process messages without any downtime.
Which solution meets these requirements MOST cost-effectively?

A. Use Reserved Instances exclusively to handle the maximum capacity required.
B. Use Reserved Instances for the baseline capacity and use On-Demand Instances to handle additional capacity.
C. Use Reserved Instances for the baseline capacity and use Spot Instances to handle additional capacity.
D. Use Spot Instances exclusively to handle the maximum capacity required.

Answer: B

Explanation:
We recommend that you use On-Demand Instances for applications with short-term, irregular workloads that cannot be interrupted. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-on-demand-instances.

NEW QUESTION # 469
A company needs to export its database once a day to Amazon S3 for other teams to access. The exported object size vanes between 2 GB and 5 GB. The S3 access pattern for the data is variable and changes rapidly.
The data must be immediately available and must remain accessible for up to 3 months. The company needs the most cost-effective solution that will not increase retrieval time Which S3 storage class should the company use to meet these requirements?

A. S3 Glacier Instant Retrieval
B. S3 Standard
C. S3 Intelligent-Tiering
D. S3 Standard-Infrequent Access (S3 Standard-IA)

Answer: D

Explanation:
S3 Intelligent-Tiering is a cost-optimized storage class that automatically moves data to the most cost-effective access tier based on changing access patterns. Although it offers cost savings, it also introduces additional latency and retrieval time into the data retrieval process, which may not meet the requirement of "immediately available" data. On the other hand, S3 Standard-Infrequent Access (S3 Standard-IA) provides low cost storage with low latency and high throughput performance. It is designed for infrequently accessed data that can be recreated if lost, and can be retrieved in a timely manner if required. It is a cost-effective solution that meets the requirement of immediately available data and remains accessible for up to 3 months.

NEW QUESTION # 470
A company has an employee web portal. Employees log in to the portal to view payroll details. The company is developing a new system to give employees the ability to upload scanned documents for reimbursement.
The company runs a program to extract text-based data from the documents and attach the extracted information to each employee's reimbursement IDs for processing.
The employee web portal requires 100% uptime. The document extract program runs infrequently throughout the day on an on-demand basis. The company wants to build a scalable and cost-effective new system that will require minimal changes to the existing web portal. The company does not want to make any code changes.
Which solution will meet these requirements with the LEAST implementation effort?

A. Create an Amazon S3 bucket to host the web portal. Use Amazon API Gateway and an AWS Lambda function for the existing functionalities. Use the Lambda function to run the document extract program.Invoke the Lambda function when the API that is associated with a new document upload is called.
B. Purchase a Savings Plan to run the web portal and the document extract program. Run the web portal and the document extract program in an Auto Scaling group.
C. Run Amazon EC2 On-Demand Instances in an Auto Scaling group for the web portal. Use an AWS Lambda function to run the document extract program. Invoke the Lambda function when an employee uploads a new reimbursement document.
D. Run Amazon EC2 Spot Instances in an Auto Scaling group for the web portal. Run the document extract program on EC2 Spot Instances Start document extract program instances when an employee uploads a new reimbursement document.

Answer: C

Explanation:
This solution offers the most scalable and cost-effective approach with minimal changes to the existing web portal and no code modifications.
Amazon EC2 On-Demand Instances in an Auto Scaling Group: Running the web portal on EC2 On- Demand instances ensures 100% uptime and scalability. The Auto Scaling group will maintain the desired number of instances, automatically scaling up or down as needed, ensuring high availability for the employee web portal.
AWS Lambda for Document Extraction: Lambda is a serverless compute service that allows you to run code in response to events without provisioning or managing servers. By using Lambda to run the document extraction program, you can trigger the function whenever an employee uploads a document. This approach is cost-effective since you only pay for the compute time used by the Lambda function.
* No Code Changes Required: This solution integrates with the existing infrastructure with minimal implementation effort and does not require any modifications to the web portal's code.
* Why Not Other Options?:
* Option B (Spot Instances): Spot Instances are not suitable for workloads requiring 100% uptime, as they can be terminated by AWS with short notice.
* Option C (Savings Plan): A Savings Plan could reduce costs but does not address the requirement for running the document extraction program efficiently or without code changes.
* Option D (S3 with API Gateway and Lambda): This would require significant changes to the existing web portal setup, including moving the portal to S3 and reconfiguring its architecture, which contradicts the requirement of minimal implementation effort and no code changes.

NEW QUESTION # 471
A robotics company is designing a solution for medical surgery The robots will use advanced sensors, cameras, and Al algorithms to perceive their environment and to complete surgeries.
The company needs a public load balancer in the AWS Cloud that will ensure seamless communication with backend services. The load balancer must be capable of routing traffic based on the query strings to different target groups. The traffic must also be encrypted Which solution will meet these requirements?

A. Use an Application Load Balancer with a certificate attached from AWS Certificate Manager (ACM).
Use query parameter-based routing.
B. Use a Gateway Load Balancer. Import a generated certificate in AWS Identity and Access Management (1AM). Attach the certificate to the load balancer. Use HTTP path-based routing.
C. Use a Network Load Balancer. Import a generated certificate in AWS Identity and Access Management (1AM). Attach the certificate to the load balancer. Use query parameter-based routing.
D. Use a Network Load Balancer with a certificate attached from AWS Certificate Manager (ACM) Use query parameter-based routing

Answer: A

Explanation:
* Understanding the Requirement: The robotics company needs a public load balancer to ensure seamless communication with backend services, route traffic based on query strings, and encrypt traffic.
* Analysis of Options:
* Network Load Balancer with ACM Certificate: NLBs primarily operate at the transport layer (Layer 4) and do not natively support query parameter-based routing, which is a Layer 7 feature.
* Gateway Load Balancer with IAM Certificate: Gateway Load Balancers are designed for deploying, scaling, and managing third-party virtual appliances and do not support HTTP path-based or query parameter-based routing.
* Application Load Balancer with ACM Certificate: ALBs operate at the application layer (Layer
7), supporting features like query parameter-based routing and SSL/TLS termination with ACM certificates.
* Network Load Balancer with IAM Certificate: As with the first option, NLBs do not support
* query parameter-based routing, making it unsuitable for this requirement.
* Best Solution:
* Application Load Balancer with ACM Certificate: This option provides the necessary Layer 7 routing capabilities and SSL/TLS termination to meet the requirements for query parameter-based routing and encrypted communication.
