  ---

  Explanation

  Amazon Relational Database Service (Amazon RDS) is the AWS service that the company should use to migrate its Microsoft SQL Server database management system from on premises to the AWS Cloud. Amazon RDS is a fully managed service that provides a scalable, secure, and high-performance relational database platform. Amazon RDS supports several database engines, including Microsoft SQL Server. Amazon RDS reduces the management overhead for the database environment by taking care of tasks such as provisioning, patching, backup, recovery, and monitoring. For more information, see What is Amazon Relational Database Service (Amazon RDS)? and Amazon RDS for SQL Server.

• Question 373:

  A company wants to push VPC Flow Logs to an Amazon S3 bucket.

  A company wants to optimize long-term compute costs of AWS Lambda functions and Amazon EC2 instances.

  Which AWS purchasing option should the company choose to meet these requirements?

  A. Dedicated Hosts
  B. Compute Savings Plans
  C. Reserved Instances
  D. Spot Instances
  B. Compute Savings Plans

  ---

  Explanation

  Compute Savings Plans are a flexible and cost-effective way to optimize long-term compute costs of AWS Lambda functions and Amazon EC2 instances. With Compute Savings Plans, customers can commit to a consistent amount of compute usage (measured in $/hour) for a 1-year or 3-year term and receive a discount of up to 66% compared to On-Demand prices3. Dedicated Hosts are physical servers with EC2 instance capacity fully dedicated to the customer's use. They are suitable for customers who have specific server-bound software licenses or compliance requirements4. Reserved Instances are a pricing model that provides a significant discount (up to 75%) compared to On- Demand pricing and a capacity reservation for EC2 instances. They are available in 1-year or 3-year terms and different payment options5. Spot Instances are spare EC2 instances that are available at up to 90% discount compared to On-Demand prices. They are suitable for customers who have flexible start and end times, can withstand interruptions, and can handle excess capacity.

• Question 374:

  A company wants to migrate its high-performance computing (HPC) application to Amazon EC2 instances. The application has multiple components. The application must have fault tolerance and must have the ability to fail over automatically.

  Which AWS infrastructure solution will meet these requirements with the LEAST latency between components?

  A. Multiple AWS Regions
  B. Multiple edge locations
  C. Multiple Availability Zones
  D. Regional edge caches
  C. Multiple Availability Zones

  ---

  Explanation

  Using EC2 instances in multiple Availability Zones is an AWS infrastructure solution that meets the requirements of migrating a high performance computing (HPC) application to AWS with fault tolerance and failover capabilities, and with the least latency between components. An Availability Zone is a physically isolated location within an AWS Region that has its own power, cooling, and network connectivity. EC2 instances within the same Region can communicate with each other using low-latency private IP addresses. By using EC2 instances in multiple Availability Zones, the company can achieve fault tolerance and failover for their HPC application, because they can distribute the workload and data across different locations that are independent of each other. If one Availability Zone becomes unavailable or impaired, the company can redirect the traffic and data to another Availability Zone without affecting the performance and availability of the application5

• Question 375:

  Which AWS Cloud Adoption Framework (AWS CAF) perspective focuses on organizing an inventory of data products in a data catalog?

  A. Operations
  B. Governance
  C. Business
  D. Platform
  B. Governance

  ---

  Explanation

  In the AWS Cloud Adoption Framework (AWS CAF), the Governance perspective focuses on aligning IT strategy and goals with business processes, which includes managing data assets, setting up an inventory of data products, and ensuring that data cataloging and metadata management are in place. This perspective is crucial for organizing data products and services, which aligns with building a comprehensive data catalog. Other perspectives like Operations, Business, and Platform do not specifically address the management of a data catalog.

• Question 376:

  Which AWS service extends AWS infrastructure and services to on-premises locations to support workloads that require low latency and local data processing?

  A. AWS Outposts
  B. Amazon Connect
  C. Amazon Lightsail
  D. AWS Direct Connect
  A. AWS Outposts

• Question 377:

  Which AWS services allow users to monitor and retain records of account activities that include governance, compliance, and auditing? (Select TWO.)

  A. Amazon CloudWatch
  B. AWS CloudTrail
  C. Amazon GuardDuty
  D. AWS Shield
  E. AWS WAF
  A. Amazon CloudWatch
  B. AWS CloudTrail

  ---

  Explanation

  Amazon CloudWatch and AWS CloudTrail are the AWS services that allow users to monitor and retain records of account activities that include governance, compliance, and auditing. Amazon CloudWatch is a service that collects and tracks metrics, collects and monitors log files, and sets alarms. AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. Amazon GuardDuty, AWS Shield, and AWS WAF are AWS services that provide security and protection for AWS resources, but they do not monitor and retain records of account activities. These concepts are explained in the AWS Cloud Practitioner Essentials course3.

• Question 378:

  A company is running an Amazon EC2 instance in a VPC.

  Which of the following can the company use to route and filter incoming network requests for the EC2 instance?

  A. Route tables and web application firewalls
  B. Security groups and route tables
  C. Security groups and a network intrusion system
  D. Route tables and AWS Shield
  B. Security groups and route tables

  ---

  Explanation

  Security groups control inbound and outbound traffic to an Amazon EC2 instance, acting as virtual firewalls. Route tables, on the other hand, determine the traffic's path between subnets within a Virtual Private Cloud (VPC) or to a virtual private gateway for accessing resources outside the VPC.

• Question 379:

  Which AWS service is a continuous delivery and deployment solution?

  A. AWSAppSync
  B. AWS CodePipeline
  C. AWS Cloud9
  D. AWS CodeCommit
  B. AWS CodePipeline

  ---

  Explanation

  AWS CodePipeline is a continuous delivery and deployment service that automates the release process of software applications across different stages, such as source code, build, test, and deploy2. AWSAppSync, AWS Cloud9, and AWS CodeCommit are other AWS services related to application development, but they do not provide continuous delivery and deployment solutions34 .

• Question 380:

  AWS has the ability to achieve lower pay-as-you-go pricing by aggregating usage across hundreds of thousands of users.

  This describes which advantage of the AWS Cloud?

  A. Launch globally in minutes
  B. Increase speed and agility
  C. High economies of scale
  D. No guessing about compute capacity
  C. High economies of scale

  ---

  Explanation

  AWS has the ability to achieve lower pay-as-you-go pricing by aggregating usage across hundreds of thousands of users. This means that AWS can leverage its massive scale and purchasing power to reduce the costs of infrastructure, hardware, software, and operations. These savings are then passed on to the customers, who only pay for the resources they use. You can learn more about the AWS pricing model from [this webpage] or [this digital course].
