A company wants to migrate critical on-premises production systems to Amazon EC2 instances. The production instances will be used for at least 3 years. The company wants a pricing option that will minimize cost.
Which solution will meet these requirements?
A. On-Demand Instances
B. Reserved Instances
C. Spot Instances
D. AWS Free Tier
Show Answer
Correct Answer: B
Explanation: The workloads will run continuously for at least 3 years. Reserved Instances provide significant discounts compared to On-Demand pricing when you commit to a 1- or 3-year term, making them the most cost-effective option for long-term, steady-state production workloads. Spot Instances are interruptible, On-Demand is more expensive long term, and Free Tier does not apply to production use.
Question 113
A company has moved all its infrastructure to the AWS Cloud. To plan ahead for each quarter, the finance team wants to track the cost and usage data of all resources from previous months. The finance team wants to automatically generate reports that contains the data.
Which AWS service or feature should the finance team use to meet these requirements?
A. Amazon Detective
B. AWS Pricing Calculator
C. AWS Budgets
D. AWS Savings Plans
Show Answer
Correct Answer: C
Explanation: Among the given options, AWS Budgets is the only service designed to track AWS costs and usage over time and provide automated reports and alerts. The other options do not provide historical cost and usage reporting (Detective is for security, Pricing Calculator is for estimates, and Savings Plans is for purchasing discounts). While AWS Cost Explorer or Cost and Usage Reports would be more precise, they are not listed, making AWS Budgets the best correct choice here.
Question 114
A company wants to deploy a web application as a containerized application. The company wants to use a managed service that can automatically create container images from source code and deploy the containerized application.
Which AWS service will meet these requirements?
A. AWS Elastic Beanstalk
B. Amazon Elastic Container Service (Amazon ECS)
C. AWS App Runner
D. Amazon EC2
Show Answer
Correct Answer: C
Explanation: The requirement is a managed service that can automatically build container images from source code and deploy a containerized web application. AWS App Runner directly supports deploying from source repositories, automatically builds the container image, provisions infrastructure, handles scaling, and manages deployments. ECS requires you to build and manage container images and orchestration yourself, Elastic Beanstalk is platform-focused rather than container-image–centric, and EC2 is unmanaged infrastructure.
Question 115
A company wants to migrate to the AWS Cloud. The company needs the ability to acquire resources when the resources are necessary. The company also needs the ability to release those resources when the resources are no longer necessary.
Which architecture concept of the AWS Cloud meets these requirements?
A. Elasticity
B. Availability
C. Reliability
D. Durability
Show Answer
Correct Answer: A
Explanation: Elasticity in the AWS Cloud refers to the ability to automatically scale resources up or down as needed. This directly matches the requirement to acquire resources when they are necessary and release them when they are no longer needed. Availability, reliability, and durability address system uptime, fault tolerance, and data persistence, not dynamic resource scaling.
Question 116
A company wants to build graph queries for real-time fraud pattern detection.
Which AWS service will meet this requirement?
A. Amazon Neptune
B. Amazon DynamoDB
C. Amazon Timestream
D. Amazon Forecast
Show Answer
Correct Answer: A
Explanation: Real-time fraud pattern detection requires graph queries to analyze complex relationships and connections between entities. Amazon Neptune is a fully managed graph database service designed specifically for storing and querying graph data using languages like Gremlin and SPARQL, making it ideal for fraud detection use cases. The other options are not graph databases and are not optimized for relationship-based queries.
Question 117
A company that is planning to migrate to the AWS Cloud is based in an isolated area that has limited internet connectivity. The company needs to perform local data processing on premises. The company needs a solution that can operate without a stable internet connection.
Which AWS service will meet these requirements?
A. Amazon S3
B. AWS Snowball Edge
C. AWS Storage Gateway
D. AWS Backup
Show Answer
Correct Answer: B
Explanation: AWS Snowball Edge is designed for environments with limited or no internet connectivity and can perform local data processing and storage on premises. It provides compute, storage, and AWS services at the edge, operating independently of a stable internet connection, which fits the company’s requirements.
Question 118
A company is planning to migrate to the AWS Cloud. The company is conducting organizational transformation and wants to become more responsive to customer inquiries and feedback.
Which task should the company perform to meet these requirements, according to the AWS Cloud Adoption Framework (AWS CAF)? (Choose two.)
A. Realign teams to focus on products and value streams.
B. Create new value propositions with new products and services.
C. Use agile methods to rapidly iterate and evolve.
D. Use a new data and analytics platform to create actionable insights.
E. Migrate and modernize legacy infrastructure.
Show Answer
Correct Answer: A, C
Explanation: According to the AWS Cloud Adoption Framework, improving responsiveness to customer inquiries and feedback is part of the People and Business perspectives of organizational transformation. Realigning teams around products and value streams makes the organization more customer-centric and reduces handoffs. Using agile methods enables rapid iteration based on customer feedback, increasing responsiveness and continuous improvement.
Question 119
Which benefits does a company gain when the company moves from on-premises IT architecture to the AWS Cloud? (Choose two.)
A. Reduced or eliminated tasks for hardware troubleshooting, capacity planning, and procurement
B. Elimination of the need for trained IT staff
C. Automatic security configuration of all applications that are migrated to the cloud
D. Elimination of the need for disaster recovery planning
E. Faster deployment of new features and applications
Show Answer
Correct Answer: A, E
Explanation: Moving to AWS shifts responsibility for physical infrastructure to AWS, reducing or eliminating tasks like hardware troubleshooting, capacity planning, and procurement. Cloud services also enable rapid provisioning and scalability, allowing companies to deploy new features and applications much faster. The other options are incorrect because IT staff, security configuration, and disaster recovery planning are still required, though they are simplified.
Question 120
A company has data lakes designed for high performance computing (HPC) workloads.
Which Amazon EC2 instance type should the company use to meet these requirements?
A. General purpose instances
B. Compute optimized instances
C. Memory optimized instances
D. Storage optimized instances
Show Answer
Correct Answer: B
Explanation: High Performance Computing (HPC) workloads are primarily CPU- and network-intensive. Amazon EC2 compute optimized instances are specifically designed for compute-heavy tasks and are explicitly recommended by AWS for HPC, scientific modeling, batch processing, and similar workloads. Storage optimized instances focus on high disk I/O throughput, which is not the defining requirement of HPC itself.
Question 121
A company wants to migrate its server-based applications to the AWS Cloud. The company wants to determine the total cost of ownership for its compute resources that will be hosted on the AWS Cloud.
Which combination of AWS services or tools will meet these requirements? (Choose two.)
A. AWS Pricing Calculator
B. Migration Evaluator
C. AWS Support Center
D. AWS Application Discovery Service
E. AWS Database Migration Service (AWS DMS)
Show Answer
Correct Answer: A, B
Explanation: To determine total cost of ownership for compute resources in AWS, the company needs tools that estimate and model costs. The AWS Pricing Calculator estimates AWS compute pricing based on selected services and configurations. Migration Evaluator (formerly TSO Logic) analyzes existing on-premises workloads, performs right-sizing, and provides a detailed TCO comparison between on-premises and AWS. Together, these tools meet the requirement. The other options do not focus on cost estimation or TCO analysis.
