A company wants to improve employee productivity by providing a way for employees to search for questions and retrieve specific answers. The company wants to use a single intelligent search interface.
Which AWS service will meet these requirements?
A. Amazon Connect
B. Amazon Kendra
C. Amazon Lex
D. Amazon Comprehend
Show Answer
Correct Answer: B
Explanation: Amazon Kendra is AWS's intelligent enterprise search service. It enables employees to use a single natural language search interface to search across enterprise content and retrieve specific answers, improving productivity. Amazon Connect is a contact center service, Amazon Lex builds conversational chatbots, and Amazon Comprehend performs natural language processing and text analysis rather than enterprise search.
Question 93
A company is releasing a business-critical application. Before the release, the company needs strategic planning assistance from AWS. During the release, the company needs AWS infrastructure event management and real-time support.
What should the company do to meet these requirements?
A. Access AWS Trusted Advisor
B. Contact the AWS Partner Network (APN)
C. Sign up for AWS Enterprise Support
D. Contact AWS Professional Services
Show Answer
Correct Answer: C
Explanation: AWS Enterprise Support is the only option that combines strategic planning assistance through a Technical Account Manager (TAM), Infrastructure Event Management (IEM) for business-critical launches, and 24/7 real-time access to AWS support engineers. Trusted Advisor provides recommendations only, APN connects customers with partners, and AWS Professional Services offers consulting engagements but not ongoing IEM and real-time operational support.
Question 94
A company purchased Amazon EC2 Standard Reserved Instances (RIs) for a workload in the AWS Cloud. The company needs to move part of the workload to an instance family that does not match the instance family of these Standard RIs.
How can the company take advantage of the Standard RIs that it no longer needs?
A. Contact the AWS Support team, and ask the team to sell the Standard RIs
B. Sell the Standard RIs on the Amazon EC2 Reserved Instance Marketplace
C. Sell the Standard RIs as a third-party seller on the AWS Marketplace
D. Convert the Standard RIs to Savings Plans
Show Answer
Correct Answer: B
Explanation: Standard Reserved Instances cannot be converted to other instance families or into Savings Plans. If they are no longer needed, eligible Standard RIs can be sold on the Amazon EC2 Reserved Instance Marketplace. AWS Support does not sell them on a customer's behalf, and the AWS Marketplace is for software products, not EC2 RIs.
Question 95
Which AWS service supports MySQL database engines?
A. Amazon Dynamo DВ
B. Amazon RDS
C. Amazon DocumentDB (with MongoDB compatibility)
D. Amazon ElastiCache
Show Answer
Correct Answer: B
Explanation: Amazon RDS is AWS's managed relational database service and supports MySQL, along with PostgreSQL, MariaDB, Oracle, SQL Server, and Amazon Aurora. DynamoDB is NoSQL, DocumentDB is MongoDB-compatible, and ElastiCache is an in-memory caching service.
Question 96
A company plans to onboard new employees that will be working remotely. The company needs to set up Windows virtual desktops to create a working environment for the new employees. The employees must be able access the working environment from anywhere and by using their computer or a web browser.
Which AWS service or feature will meet these requirements?
A. Dedicated Hosts
B. AWS Global Accelerator
C. Amazon Workspaces
D. Amazon CloudFront
Show Answer
Correct Answer: C
Explanation: Amazon WorkSpaces is AWS's managed Desktop as a Service (DaaS) offering that provides persistent Windows or Linux virtual desktops accessible from client applications or a web browser from virtually anywhere. Dedicated Hosts are for dedicated physical servers, Global Accelerator improves application availability and performance, and CloudFront is a content delivery network, none of which provide virtual desktop environments.
Question 97
Which AWS offering can analyze a company’s AWS environment to discover security vulnerabilities on Amazon EC2 instances?
A. Amazon Inspector
B. Amazon Macie
C. AWS Shield Standard
D. Security groups
Show Answer
Correct Answer: A
Explanation: Amazon Inspector is the AWS security assessment service that analyzes Amazon EC2 instances for software vulnerabilities and unintended network exposure. Amazon Macie discovers and protects sensitive data, AWS Shield Standard provides DDoS protection, and security groups are virtual firewalls rather than vulnerability assessment tools.
Question 98
A company has developed a new In-house application. The company does not have a way to determine or predict the usage demand that the application will create.
Which AWS Cloud computing benefit is the company seeking?
A. Easy to use
B. Cost-effective
C. Secure
D. Scalable and high performance
Show Answer
Correct Answer: D
Explanation: When application demand is unpredictable, the key AWS Cloud benefit is the ability to scale resources up or down automatically to match workload. This elasticity provides scalable, high-performance infrastructure without needing to predict capacity in advance.
Question 99
Which type of workload should a company run on Amazon EC2 Spot Instances?
A. A steady-state workload that requires a particular EC2 instance configuration for a long period of time
B. A workload that can be interrupted and can control costs
C. A steady-state workload that does not require a long-term commitment
D. A workload that cannot be interrupted and can control costs
Show Answer
Correct Answer: B
Explanation: Amazon EC2 Spot Instances are designed for fault-tolerant, flexible workloads that can tolerate interruptions in exchange for significantly lower costs. They are not appropriate for workloads that require uninterrupted availability or long-running steady-state capacity.
Question 100
A company has multiple AWS accounts. The company needs to receive a consolidated bill from AWS and must centrally manage security and compliance.
Which AWS service or feature should the company use to meet these requirements?
A. AWS Cost and Usage Report
B. AWS Organizations
C. AWS Config
D. AWS Security Hub
Show Answer
Correct Answer: B
Explanation: AWS Organizations is the correct service because it enables centralized management of multiple AWS accounts, supports consolidated billing with a single payer account, and provides governance features such as organizational units and Service Control Policies (SCPs) to centrally manage security and compliance. AWS Cost and Usage Report only provides billing reports, AWS Config assesses resource configuration, and AWS Security Hub aggregates security findings but does not provide consolidated billing or account management.
Question 101
A company wants to provide low latency to its users around the world.
Which feature of the AWS Cloud meet this requirement?
A. Global infrastructure
B. Pay as-you-go pricing
C. Managed services
D. Economy of scale
Show Answer
Correct Answer: A
Explanation: AWS Global Infrastructure, including Regions, Availability Zones, and edge locations, allows applications and content to be deployed closer to users worldwide, reducing network latency. The other options describe pricing, service management, or cost advantages rather than latency.
