A company plans to migrate its application from on premises to the AWS Cloud. The company needs to gather usage and configuration data for the application components.
Which AWS service will meet these requirements?
A. AWS Database Migration Service (AWS DMS)
B. AWS Transfer Family
C. AWS Application Discovery Service
D. AWS Global Accelerator
Show Answer
Correct Answer: C
Explanation: AWS Application Discovery Service collects configuration, usage, and dependency data from on-premises servers and applications to help plan and accelerate migrations to AWS. AWS DMS migrates databases, AWS Transfer Family provides managed file transfer protocols, and AWS Global Accelerator improves application availability and performance, not discovery.
Question 103
A company wants a fully managed service that centralizes and automates data protection across AWS services and hybrid workloads.
Which AWS service will meet these requirements?
A. AWS Artifact
B. AWS Backup
C. AWS Batch
D. AWS Shield
Show Answer
Correct Answer: B
Explanation: AWS Backup is the fully managed service that centralizes and automates data protection across supported AWS services and hybrid workloads. AWS Artifact provides compliance reports, AWS Batch runs batch computing jobs, and AWS Shield protects against DDoS attacks.
Question 104
A company needs to run an application on Amazon EC2 instances without interruption.
Which EC2 instance purchasing option will meet this requirement MOST cost-effectively?
A. Standard Reserved Instances
B. Convertible Reserved Instances
C. On-Demand Instances
D. Spot Instances
Show Answer
Correct Answer: C
Explanation: The requirement is uninterrupted operation. Spot Instances do not meet this because they can be interrupted. Reserved Instances (Standard or Convertible) are billing discounts tied to a 1- or 3-year commitment rather than a requirement for availability; the question does not state a long-term workload. Without a stated commitment period, On-Demand Instances are the most appropriate and cost-effective option that satisfies the requirement without assuming a multi-year commitment.
Question 105
A company wants to explore and analyze data in Amazon S3 by using a programming language.
Which AWS service will meet these requirements?
A. Amazon Kendra
B. Amazon Athena
C. Amazon Comprehend
D. Amazon SageMaker
Show Answer
Correct Answer: B
Explanation: Amazon Athena is the AWS service designed to interactively explore and analyze data stored in Amazon S3 using SQL. It is serverless and requires no infrastructure management. The other options serve different purposes: Amazon Kendra is for intelligent search, Amazon Comprehend is for natural language processing, and Amazon SageMaker is for building and deploying machine learning models.
Question 106
Which AWS service or tool provides recommendations to help users get rightsized Amazon EC2 instances based on historical workload usage data?
A. AWS Pricing Calculator
B. AWS Compute Optimizer
C. AWS App Runner
D. AWS Systems Manager
Show Answer
Correct Answer: B
Explanation: AWS Compute Optimizer analyzes historical utilization metrics and configuration data for Amazon EC2 instances and other supported resources to provide rightsizing recommendations that improve cost and performance. The other options do not perform historical workload-based rightsizing recommendations.
Question 107
A company wants to build, train, and deploy machine learning (ML) models.
Which AWS service can the company use to meet this requirement?
A. Amazon Personalize
B. Amazon Comprehend
C. Amazon Forecast
D. Amazon SageMaker
Show Answer
Correct Answer: D
Explanation: Amazon SageMaker is the AWS service specifically designed to build, train, and deploy machine learning models. The other options are specialized AI services: Amazon Personalize for recommendations, Amazon Comprehend for natural language processing, and Amazon Forecast for time-series forecasting.
Question 108
A company has multiple SQL-based databases located in a data center. The company needs to migrate all database servers to the AWS Cloud to reduce the cost of operating physical servers.
Which AWS service or resource will meet these requirements with the LEAST operational overhead?
A. Amazon EC2 instances
B. Amazon RDS
C. Amazon DynamoDB
D. OpenSearch
Show Answer
Correct Answer: B
Explanation: Amazon RDS is a fully managed relational database service that supports SQL database engines and significantly reduces operational overhead by handling provisioning, patching, backups, monitoring, and high availability. Running databases on Amazon EC2 requires managing the OS and database software. DynamoDB is a NoSQL database, so it is not a direct replacement for SQL databases. OpenSearch is a search and analytics service, not a relational database.
Question 109
Which pillar of the AWS Well-Architected Framework focuses on the ability to recover automatically from service interruptions?
A. Security
B. Performance efficiency
C. Operational excellence
D. Reliability
Show Answer
Correct Answer: D
Explanation: The Reliability pillar of the AWS Well-Architected Framework focuses on ensuring workloads perform correctly and consistently, including the ability to recover automatically from failures and service interruptions. It emphasizes fault tolerance, automatic recovery, and resilient system design.
Question 110
Which AWS Well-Architected Framework concept represents a system's ability to remain functional when the system encounters operational problems?
A. Consistency
B. Elasticity
C. Durability
D. Latency
Show Answer
Correct Answer: C
Explanation: Durability refers to the ability of a system or data to continue functioning and persist despite failures or operational issues. The other options do not describe resilience to operational problems: consistency is about data state, elasticity is scaling with demand, and latency is response time.
Question 111
Which AWS Cloud Adoption Framework (AWS CAF) perspective focuses on real-time insights and answers questions about strategy?
A. Operations
B. People
C. Business
D. Platform
Show Answer
Correct Answer: C
Explanation: The AWS Cloud Adoption Framework (AWS CAF) Business perspective focuses on ensuring that business strategies and IT investments are aligned. It emphasizes business outcomes, value realization, and providing leaders with the insights needed to answer strategic questions and make informed decisions. The Operations perspective focuses on running and monitoring workloads, the People perspective on organizational capabilities and change management, and the Platform perspective on technology infrastructure and services.
