How does the AWS Cloud help companies build agility into their processes and cloud infrastructure?
A. Companies can avoid provisioning too much capacity when they do not know how much capacity is required.
B. Companies can expand into new geographic regions.
C. Companies can access a range of technologies to experiment and innovate quickly.
D. Companies can pay for IT resources only when they use the resources.
Show Answer
Correct Answer: C
Explanation: Agility in the AWS Cloud refers to the ability to quickly adapt, iterate, and respond to changing business needs. AWS provides a broad range of managed services and technologies that companies can rapidly adopt, test, and scale without heavy upfront investment. This enables faster experimentation, innovation, and iteration, which is the core of building agility into processes and cloud infrastructure. While the other options describe cost efficiency or global reach, they are not as directly tied to agility as rapid experimentation and innovation.
Question 293
Which AWS service can a company use to manage encryption keys in the cloud?
A. AWS License Manager
B. AWS Certificate Manager (ACM)
C. AWS CloudHSM
D. AWS Directory Service
Show Answer
Correct Answer: C
Explanation: AWS CloudHSM is designed to generate, store, and manage encryption keys using dedicated hardware security modules (HSMs). It gives customers full control over their cryptographic keys, unlike services focused on licenses, directories, or certificates.
Question 294
A company plans to migrate its custom marketing application and order-processing application to AWS. The company needs to deploy the applications on different types of instances with various configurations of CPU, memory, storage, and networking capacity.
Which AWS service should the company use to meet these requirements?
A. AWS Lambda
B. Amazon Cognito
C. Amazon Athena
D. Amazon EC2
Show Answer
Correct Answer: D
Explanation: The requirement is to run custom applications on different instance types with configurable CPU, memory, storage, and networking. Amazon EC2 provides a wide range of instance families and sizes to meet these needs. AWS Lambda is serverless with no instance control, Amazon Cognito is for identity management, and Amazon Athena is a query service for S3 data, so they do not fit the requirement.
Question 295
Which programming languages does AWS Cloud Development Kit (AWS CDK) currently support? (Choose two.)
A. Python
B. Swift
C. TypeScript
D. Ruby
E. PHP
Show Answer
Correct Answer: A, C
Explanation: AWS CDK currently supports Python and TypeScript (along with Java, C#/.NET, JavaScript, and Go). Among the given options, only Python and TypeScript are supported; Swift, Ruby, and PHP are not.
Question 296
A company needs to purchase Amazon EC2 instances to support an application that will run continuously for more than 1 year.
Which EC2 instance purchasing option meets these requirements MOST cost-effectively?
A. Dedicated Instances
B. Spot Instances
C. Reserved Instances
D. On-Demand Instances
Show Answer
Correct Answer: C
Explanation: For workloads that run continuously for more than one year, Reserved Instances provide a significant discount compared to On-Demand pricing in exchange for a 1- or 3-year commitment. Spot Instances are not suitable for continuous workloads due to interruptions, Dedicated Instances are more expensive and used for compliance needs, and On-Demand is the least cost-effective for long-term steady usage.
Question 297
Which AWS team or offering helps users accelerate cloud adoption through paid engagements in any of several specialty practice areas?
A. AWS Enterprise Support
B. AWS solutions architects
C. AWS Professional Services
D. AWS account managers
Show Answer
Correct Answer: C
Explanation: AWS Professional Services is a paid AWS offering that provides hands-on expert guidance across multiple specialty practice areas (such as migration, modernization, security, and DevOps) to help customers accelerate cloud adoption. Other options either provide support, advisory roles, or account management rather than structured paid engagements.
Question 298
Which AWS service helps users plan and track their server and application inventory migration data to AWS?
A. Amazon CloudWatch
B. AWS DataSync
C. AWS Migration Hub
D. AWS Application Migration Service
Show Answer
Correct Answer: C
Explanation: The service that helps users plan and track their server and application inventory migration data to AWS is AWS Migration Hub. Migration Hub provides a centralized dashboard to discover, assess, plan, and track the progress of application and server migrations across multiple AWS and partner migration tools. AWS Application Migration Service focuses on executing server migrations, not planning and tracking inventory at a high level.
Question 299
A company needs access to checks and recommendations that help the company follow AWS best practices for cost optimization, security, fault tolerance, performance, and service quotas.
Which combination of an AWS service and AWS Support plan on the AWS account will meet these requirements?
A. AWS Trusted Advisor with AWS Developer Support
B. AWS Health Dashboard with AWS Enterprise Support
C. AWS Trusted Advisor with AWS Business Support
D. AWS Health Dashboard with AWS Enterprise On-Ramp Support
Show Answer
Correct Answer: C
Explanation: The requirements describe AWS Trusted Advisor checks across cost optimization, security, fault tolerance, performance, and service quotas. Full access to all Trusted Advisor checks is included with AWS Business Support (and higher). Developer Support only provides limited Trusted Advisor checks, and AWS Health Dashboard does not provide best-practice recommendations. Therefore, AWS Trusted Advisor with AWS Business Support is the correct combination.
