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: AWS Cloud allows users to avoid guessing infrastructure capacity by enabling elastic scaling and on-demand resource provisioning. Option B is incorrect because AWS shifts spending from capital expense to variable expense rather than requiring ownership of hardware. Option C is incorrect because AWS manages the underlying infrastructure. Option D is incorrect because for managed services AWS, not the customer, manages the operating systems.
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: The AWS Cloud's cost-effectiveness is characterized by replacing large upfront capital expenditures with variable, pay-as-you-go operational expenses, and by passing on economies of scale from AWS's massive infrastructure to customers through lower costs. The other options describe different cloud benefits (global deployment, agility, and shared responsibility) rather than 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 being moved to an architecture split between the local data center and AWS. An environment spanning both on-premises infrastructure and the cloud is a hybrid architecture, so this is a migration 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: On-Demand Instances are the most cost-effective choice for a workload that runs only about 3 hours per week and cannot be interrupted. Spot Instances are unsuitable because they can be interrupted. Compute Savings Plans and Convertible Reserved Instances require a 1- or 3-year commitment and are intended for sustained or committed usage; with only ~3 hours of weekly runtime, the commitment is unlikely to be cost-effective compared with paying On-Demand rates.
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: AWS Service Catalog is designed to govern infrastructure as code (IaC) by centrally managing approved CloudFormation templates and Terraform configurations as products. It helps organizations enforce standardized, compliant deployments and meet governance and compliance requirements. AWS Artifact provides compliance reports, Resource Explorer helps find resources, and License Manager manages software licenses.
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: Amazon S3 Glacier Instant Retrieval is designed for data that is rarely accessed but still needs millisecond retrieval. The data is accessed only twice per year, making it an infrequent-access archival workload. S3 Intelligent-Tiering is intended for unknown or changing access patterns and includes monitoring charges, so it is not the lowest-cost fit for this predictable pattern. S3 Standard is more expensive for storage, and S3 Outposts is not a storage class for this use case.
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 is AWS object storage and supports serving objects via public URLs (when configured for public access or through appropriate policies), allowing users to download files directly. Amazon EBS and Amazon EFS are storage services attached to compute resources, and Amazon Redshift is a data warehouse.
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 (AWS CAF) perspectives include Business, People, Governance, Platform, Security, and Operations. Among the options provided, Security and Business are official AWS CAF perspectives. Cloud fluency and Change acceleration are capabilities or concepts rather than perspectives, and Architecture is not one of the named AWS 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 the correct choice because it is AWS's global content delivery network (CDN). It caches and serves website content from edge locations close to users around the world, reducing latency and improving performance for a global audience. Amazon Route 53 provides DNS routing and can direct users to appropriate endpoints, but it does not cache or accelerate content delivery. Elastic Load Balancing distributes traffic across targets within regions, and AWS Lambda is a serverless compute service.
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 stateful virtual firewalls attached to EC2 instances and can control inbound and outbound traffic between specific EC2 instances by referencing security groups. Network ACLs operate at the subnet level, AWS WAF protects web applications, and Amazon GuardDuty is a threat detection service.
