SAP-C02 Accelerate Workload Migration and Modernization Practice Test 14 — 15 Questions

Question 1

A company is migrating a legacy application that uses a proprietary binary protocol for communication. The application communicates over TCP/IP. The company wants to modernize the communication layer to use a RESTful API. Which TWO approaches should the company consider?

Accepted Answer

Use Amazon API Gateway and AWS Lambda to create a REST API that translates requests to the legacy protocol.. Options A and C are correct. Option A: Wrapping the legacy protocol with a REST API using API Gateway and Lambda allows gradual modernization. Option C: Refactoring the application to use HTTP directly is the ideal long-term solution. Option B: Amazon MQ is for messaging, not REST. Option D: AWS App Mesh is for service mesh, not protocol translation. Option E: CloudFront is a CDN, not for protocol translation.

Answer

Replace the binary protocol with Amazon MQ.

Answer

Use AWS App Mesh to convert the binary protocol to HTTP.

Answer

Use Amazon CloudFront to cache the RESTful endpoints.

Question 4

A company is migrating data to Amazon S3 and requires that all objects uploaded to the bucket 'my-bucket' are encrypted with SSE-S3. The above IAM policy is attached to an IAM user. An application using the user's credentials attempts to upload an object without specifying the x-amz-server-side-encryption header. What will happen?

Accepted Answer

The upload fails because the Deny statement denies the request when encryption is not AES256.. Option D is correct. The Allow statement grants permission only if encryption is AES256. The Deny statement denies if encryption is not AES256. Since no encryption header is specified, the condition in the Deny statement evaluates to true (StringNotEquals), and the request is denied. Option A is wrong because the Deny statement explicitly denies. Option B is wrong because AES256 is required. Option C is wrong because the bucket policy does not override the IAM policy; both are evaluated.

Answer

The upload succeeds because the Allow statement grants permission.

Answer

The upload fails because the bucket policy overrides the IAM policy.

Answer

The upload succeeds because the object is encrypted with the default SSE-S3.

Question 5

A company is migrating a critical database server to Amazon EC2. The root volume (EBS) is configured with DeleteOnTermination=false. After migration, the company needs to ensure that if the EC2 instance fails, a new instance can be quickly launched using the same data. The company takes regular snapshots of the volume. Which statement is correct regarding the root volume's behavior?

Accepted Answer

The root volume will persist after instance termination and can be attached to another instance.. Option B is correct because with DeleteOnTermination=false, the root volume persists after instance termination. Option A is wrong because the volume persists. Option C is wrong because the snapshot schedule is independent of the DeleteOnTermination setting. Option D is wrong because the root volume can be reused by creating a new instance and attaching it.

Answer

The root volume cannot be used as a boot volume for a new instance.

Answer

The root volume will be automatically deleted when the instance is terminated.

Answer

Snapshots of the volume will be automatically deleted when the instance is terminated.

Question 6

A company is deploying a web application using the above CloudFormation template. The template fails to create the Auto Scaling group. What is the most likely cause?

Accepted Answer

The LaunchConfiguration resource type is incorrect.. Option C is correct because the launch configuration uses the wrong resource type (AWS::AutoScaling::AutoScalingGroup) instead of AWS::AutoScaling::LaunchConfiguration. Option A is wrong because t2.micro is a valid instance type. Option B is wrong because the AvailabilityZones are valid. Option D is wrong because MinSize=2 is valid.

Answer

The instance type t2.micro is not supported in us-east-1.

Answer

The MinSize value must be less than the DesiredCapacity.

Answer

The AvailabilityZones list is invalid because it uses names instead of zone IDs.

Question 7

A company is migrating a legacy on-premises application to AWS. The application uses a shared file system for user home directories. Which AWS service should the company use to minimize changes to the application while providing scalable, highly available file storage?

Accepted Answer

Amazon EFS. Option B (Amazon EFS) is correct because it provides a scalable, fully managed NFS file system that can be mounted by multiple EC2 instances, minimizing application changes. Option A (S3) is object storage, not a file system. Option C (EBS) is block storage attached to a single instance. Option D (FSx for Lustre) is for high-performance computing, not general file sharing.

Answer

Amazon FSx for Lustre

Answer

Amazon EBS

Answer

Amazon S3

Question 8
