Which of the following is an advantage that the AWS Cloud provides to users?
A. Users eliminate the need to guess about infrastructure capacity requirements.
B. Users decrease their variable costs by maintaining sole ownership of IT hardware.
C. Users maintain control of underlying IT infrastructure hardware.
D. Users maintain control of operating systems for managed services.
Show Answer
Correct Answer: A
Explanation: A key advantage of the AWS Cloud is elasticity: customers can scale resources up or down on demand, which removes the need to guess or overprovision infrastructure capacity. The other options are incorrect because AWS reduces hardware ownership, abstracts control of underlying infrastructure, and for managed services does not provide OS-level control.
Question 263
Which statements represent the cost-effectiveness of the AWS Cloud? (Choose two.)
A. Users can trade fixed expenses for variable expenses.
B. Users can deploy all over the world in minutes.
C. AWS offers increased speed and agility.
D. AWS is responsible for patching the infrastructure.
E. Users benefit from economies of scale.
Show Answer
Correct Answer: A, E
Explanation: Cost-effectiveness in AWS refers to pricing and cost savings. Trading fixed expenses for variable expenses reflects the pay-as-you-go model, reducing upfront capital costs. Economies of scale allow AWS to offer lower prices than customers could achieve on their own. The other options describe agility, global reach, or operational responsibility rather than direct cost-effectiveness.
Question 264
A user is moving a workload from a local data center to an architecture that is distributed between the local data center and the AWS Cloud.
Which type of migration is this?
A. On-premises to cloud native
B. Hybrid to cloud native
C. On-premises to hybrid
D. Cloud native to hybrid
Show Answer
Correct Answer: C
Explanation: The workload starts in a local (on‑premises) data center and is moved to an architecture split between on‑premises and AWS. That target state is a hybrid architecture, so the migration is from on‑premises to hybrid.
Question 265
A company runs Amazon EC2 instances in a research lab. The instances run for 3 hours each week and cannot be interrupted.
What is the MOST cost-effective instance purchasing option to meet these requirements?
A. Compute Savings Plan
B. On-Demand Instances
C. Convertible Reserved Instances
D. Spot Instances
Show Answer
Correct Answer: B
Explanation: The instances run only 3 hours per week and cannot be interrupted. On-Demand Instances are designed for short-term, irregular workloads with no long-term commitment and no interruption risk. Savings Plans and Reserved Instances require 1- or 3-year spend commitments that would not be cost-effective for such minimal usage, and Spot Instances are unsuitable because they can be interrupted.
Question 266
A company wants to manage its cloud resources by using infrastructure as code (IaC) templates. The company needs to meet compliance requirements.
Which AWS service should the company use to meet these requirements?
A. AWS Artifact
B. AWS Resource Explorer
C. AWS License Manager
D. AWS Service Catalog
Show Answer
Correct Answer: D
Explanation: The requirement is to manage cloud resources using infrastructure as code (IaC) templates while enforcing compliance. AWS Service Catalog allows organizations to centrally manage, govern, and distribute approved IaC templates (such as AWS CloudFormation or Terraform). By offering only pre-approved, compliant products, it ensures standardized provisioning and adherence to compliance requirements. The other options do not provide governance over IaC templates.
Question 267
A company stores a large amount of data that auditors access only twice each year.
Which Amazon S3 storage class should the company use to store the data with the LOWEST cost?
A. Amazon S3 Outposts
B. Amazon S3 Glacier Instant Retrieval
C. Amazon S3 Standard
D. Amazon S3 Intelligent-Tiering
Show Answer
Correct Answer: B
Explanation: The data is accessed very infrequently (only twice per year), so the lowest-cost option among the listed choices is an archival class. Amazon S3 Glacier Instant Retrieval is designed for rarely accessed data with very low storage cost and avoids the higher storage and monitoring fees of S3 Intelligent-Tiering. S3 Standard and S3 Outposts are significantly more expensive. Therefore, the lowest-cost suitable choice is Amazon S3 Glacier Instant Retrieval.
Question 268
A company wants to store its files in the AWS Cloud. Users need to be able to download these files directly using a public URL.
Which AWS service or feature will meet this requirement?
A. Amazon Redshift
B. Amazon Elastic Block Store (Amazon EBS)
C. Amazon Elastic File System (Amazon EFS)
D. Amazon S3
Show Answer
Correct Answer: D
Explanation: Amazon S3 allows objects to be stored and made publicly accessible via HTTP/HTTPS URLs, enabling users to directly download files. The other options are not designed for public URL-based file access (Redshift is a data warehouse, EBS is block storage for EC2, and EFS is a network file system).
Question 269
Which options are AWS Cloud Adoption Framework (AWS CAF) perspectives? (Choose two.)
A. Cloud fluency
B. Security
C. Change acceleration
D. Architecture
E. Business
Show Answer
Correct Answer: B, E
Explanation: The AWS Cloud Adoption Framework defines six perspectives: Business, People, Governance, Platform, Security, and Operations. From the options given, Security (B) and Business (E) are official AWS CAF perspectives. The other options are capabilities or concepts, not CAF perspectives.
Question 270
A company hosts its website on Amazon EC2 instances. The company needs to ensure that the website reaches a global audience and provides minimum latency to users.
Which AWS service should the company use to meet these requirements?
A. Amazon Route 53
B. Amazon CloudFront
C. Elastic Load Balancing
D. AWS Lambda
Show Answer
Correct Answer: B
Explanation: Amazon CloudFront is a global content delivery network (CDN) that caches and serves content from edge locations close to users worldwide, minimizing latency and improving performance. Route 53 handles DNS routing, Elastic Load Balancing distributes traffic within regions, and AWS Lambda is for serverless compute—not global content delivery.
Question 271
A company runs many Amazon EC2 instances in its VPC. The company wants to use a native AWS security resource to control network traffic between certain EC2 instances.
Which AWS service or feature will meet this requirement?
A. Network ACLs
B. AWS WAF
C. Amazon GuardDuty
D. Security groups
Show Answer
Correct Answer: D
Explanation: Security groups are a native AWS feature that act as instance-level virtual firewalls. They allow you to explicitly control inbound and outbound network traffic to and from specific EC2 instances, including allowing traffic only between certain instances. Network ACLs operate at the subnet level, AWS WAF protects web applications, and GuardDuty is a threat detection service, so they do not meet this requirement.
