SAP-C02 Mock Exam 73 — 25 Questions

Question 1

A company is migrating a web application to AWS and wants to use a multi-tier architecture with an Auto Scaling group of EC2 instances behind an Application Load Balancer. The company needs to store session state for the application. Which TWO approaches should the company use to store session state in a scalable and highly available manner? (Choose TWO.)

Accepted Answer

Use Amazon DynamoDB with on-demand capacity.. Options A and D are correct because ElastiCache for Redis and DynamoDB are both highly available and scalable solutions for session state. Option B is wrong because EBS is tied to a single instance. Option C is wrong because instance store is ephemeral. Option E is wrong because RDS is not optimized for session state.

Answer

Use an EC2 instance store for each instance.

Answer

Use Amazon EBS snapshots shared across instances.

Answer

Use Amazon RDS for MySQL with Multi-AZ.

Question 2

A company is planning to migrate a legacy application to AWS. The application requires a fixed IP address that clients whitelist. The company wants to achieve high availability across two Availability Zones. Which architecture should they use?

Accepted Answer

Network Load Balancer (NLB) with Elastic IPs attached to each subnet. Option B (NLB with Elastic IPs) is correct because NLB supports static IP addresses and can be associated with Elastic IPs for each AZ. Option A (ALB) provides a DNS name, not fixed IP. Option C (Global Accelerator) provides two static IPs but is more complex and costly. Option D (Classic Load Balancer) does not support Elastic IPs per AZ effectively.

Answer

AWS Global Accelerator with Application Load Balancer

Answer

Classic Load Balancer with Elastic IPs

Answer

Application Load Balancer (ALB) with EC2 instances

Question 3

A company is moving its application from on-premises to AWS. They want to use the same third-party software licenses on AWS. Which AWS purchasing option allows them to bring their own licenses?

Accepted Answer

Dedicated Hosts. Option D (Dedicated Hosts) is correct because it provides visibility and control over physical servers, allowing you to use your own licenses per socket/core. Option A (Reserved Instances) is just a billing discount. Option B (Savings Plans) also a discount. Option C (Spot Instances) are interruptible.

Answer

Savings Plans

Answer

Spot Instances

Answer

Reserved Instances

Question 9

A company is migrating a legacy application that uses hard-coded IP addresses for database connections. The company wants to refactor the application to use a more resilient architecture in AWS. Which THREE steps should the company take to modernize the database connectivity? (Choose THREE.)

Accepted Answer

Use Amazon RDS read replicas to offload read traffic and improve resilience.. Options B, C, and D are correct because using an RDS endpoint (DNS name) allows failover, modifying the application to use the DNS name removes hard-coded IPs, and using a read replica offloads read traffic. Option A is wrong because an Elastic IP is not recommended for RDS. Option E is wrong because Multi-AZ is for high availability, not for removing hard-coded IPs.

Answer

Enable Multi-AZ deployment for the RDS instance to automatically failover.

Answer

Assign an Elastic IP address to the RDS instance for consistent connectivity.

Question 10

A company is migrating a large-scale .NET application to AWS. The application uses Windows authentication and requires Active Directory integration. The company wants to reduce operational overhead. Which migration approach should they use?

Accepted Answer

Rehost on EC2 with AWS Managed Microsoft AD. Option C (Deploy on EC2 with Managed Microsoft AD) is correct because it provides Active Directory without managing domain controllers. Option A (Lift-and-shift to on-premises AD) doesn't reduce overhead. Option B (Use Cognito) is for web identity, not AD. Option D (Deploy on Lightsail) has limited AD support.

Answer

Rehost on EC2 with on-premises AD via VPN

Answer

Replatform to use Amazon Cognito for authentication

Answer

Replatform to AWS Elastic Beanstalk with Amazon Lightsail

Question 11

A company is migrating an on-premises application to AWS. The application requires low-latency access to a file system that can be mounted by multiple EC2 instances simultaneously. Which AWS storage service should they use?

Accepted Answer

Amazon EFS. Amazon EFS provides a scalable, shared file system for multiple EC2 instances. Option A is wrong because S3 is object storage, not a file system. Option B is wrong because EBS volumes can only be attached to a single instance (except multi-attach io1/io2). Option D is wrong because FSx for Windows File Server is for Windows workloads, but EFS is simpler for Linux.

Answer

Amazon S3

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS

Question 12

Refer to the exhibit. A solutions architect runs the AWS CLI command and receives the output shown. The instance was stopped 2 hours ago. The company wants to minimize costs. What should the architect do next?

Accepted Answer

Keep the instance stopped; only storage costs apply.. A stopped instance incurs charges for attached EBS volumes, but not for the instance itself. Option A is wrong because termination would delete the instance. Option B is wrong because hibernation is not possible from stopped state. Option D is wrong because starting the instance incurs costs.

Answer

Terminate the instance to avoid any further charges.

Answer

Start the instance to verify it works.

Answer

Hibernate the instance to save memory state.

Question 16

A company is migrating a web application to AWS. They want to use the same domain name for both the development and production environments, but route traffic based on the source IP address. Which AWS service can accomplish this?

Accepted Answer

Amazon Route 53 with geolocation routing policy. Option C is correct because AWS Route 53 can route traffic based on source IP using geolocation or latency routing, but more specifically, using a routing policy that considers the client's IP. Option A is wrong because ELB distributes traffic within a region, not based on client IP globally. Option B is wrong because CloudFront is a CDN, not a DNS-based routing service. Option D is wrong because Global Accelerator uses anycast IPs, not DNS.

Answer

Elastic Load Balancer (ELB)

Answer

AWS Global Accelerator

Answer

Amazon CloudFront

Question 17

A company is migrating a critical application to AWS and needs to ensure high availability across two Availability Zones. The application runs on EC2 instances behind an Application Load Balancer (ALB). The database is an on-premises SQL Server that will be migrated later. Which architecture provides high availability for the application tier during the migration?

Accepted Answer

Deploy EC2 instances in two AZs behind an ALB with cross-zone load balancing enabled.. Option A is correct because ALB distributes traffic to instances in two AZs. Option B is wrong because a single AZ is not highly available. Option C is wrong because a Network Load Balancer is for TCP/UDP, not HTTP. Option D is wrong because Route 53 alone does not provide load balancing.

Answer

Deploy EC2 instances in a single AZ with an Auto Scaling group.

Answer

Deploy EC2 instances in two AZs behind a Network Load Balancer (NLB).

Answer
