• Question 401:

  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
  A. Amazon Neptune

  ---

  Explanation

  Amazon Neptune is a fully managed graph database service optimized for storing and querying highly connected data. It supports popular graph models such as Property Graph and W3C's RDF, making it ideal for building graph queries for

  real-time fraud pattern detection and other applications that require complex relationships and data traversal.

  Option B: Amazon DynamoDB: Incorrect. It is a NoSQL database service that is not optimized for graph queries.

  Option C: Amazon Timestream: Incorrect. It is a time-series database service designed for storing and analyzing time-series data, not graph data. Option D: Amazon Forecast: Incorrect. It is a fully managed service that provides time-series

  forecasting capabilities, not for graph queries.

• Question 402:

  A company seeks cost savings in exchange for a commitment to use a specific amount of an AWS service or category ofAWS services for 1 year or 3 years. Which AWS pricing model or offering will meet these requirements?

  A. Pay-as-you-go pricing
  B. Savings Plans
  C. AWS Free Tier
  D. Volume discounts
  B. Savings Plans

  ---

  Explanation

  Savings Plans are an AWS pricing model or offering that can meet the requirements of seeking cost savings in exchange for a commitment to use a specific amount of an AWS service or category of AWS services for 1 year or 3 years. Savings Plans are flexible plans that offer significant discounts on AWS compute usage, such as EC2, Lambda, and Fargate. The company can choose from two types of Savings Plans: Compute Savings Plans and EC2 Instance Savings Plans. Compute Savings Plans provide the most flexibility and apply to any eligible compute usage, regardless of instance family, size, region, operating system, or tenancy. EC2 Instance Savings Plans provide more savings and apply to a specific instance family within a region. The company can select the amount of compute usage per hour (e.g., $10/hour) that they want to commit to for the duration of the plan (1 year or 3 years). The company will pay the discounted Savings Plan rate for the amount of usage that matches their commitment, and the regular on-demand rate for any usage beyond that

• Question 403:

  A company wants to transport 100 TB of data from its data center to AWS without using internet.

  Which AWS service will meet this requirement?

  A. AWS Snowcone
  B. AWS Snowball Edge
  C. AWS Data Exchange
  D. AWS DataSync
  B. AWS Snowball Edge

  ---

  Explanation

  AWS Snowball Edge is designed for large-scale data transfer tasks, allowing companies to transport significant amounts of data (up to petabytes) from their data centers to AWS without relying on the internet. With the ability to transfer 100 TB of data securely and efficiently, Snowball Edge is the ideal choice for this use case. AWS Snowcone is for smaller transfers, and AWS Data Exchange and DataSync are not designed for physical data transport.

• Question 404:

  A company wants to define a central data protection policy that works across AWS services for compute, storage, and database resources.

  Which AWS service will meet this requirement?

  A. AWS Batch
  B. AWS Elastic Disaster Recovery
  C. AWS Backup
  D. Amazon FSx
  C. AWS Backup

  ---

  Explanation

  The AWS service that will meet this requirement is

  C. AWS Backup. AWS Backup is a service that allows you to define a central data protection policy that works across AWS services for compute, storage, and database resources. You can use AWS Backup to create backup plans that specify the frequency, retention, and lifecycle of your backups, and apply them to your AWS resources using tags or resource IDs. AWS Backup supports various AWS services, such as Amazon EC2, Amazon EBS, Amazon RDS, Amazon DynamoDB, Amazon EFS, Amazon FSx, and AWS Storage Gateway. AWS Batch is a service that allows you to run batch computing workloads on AWS. AWS Batch does not provide a central data protection policy, but rather enables you to optimize the allocation and utilization of your compute resources. AWS Elastic Disaster Recovery is a service that allows you to prepare for and recover from disasters using AWS. AWS Elastic Disaster Recovery does not provide a central data protection policy, but rather helps you minimize downtime and data loss by replicating your applications and data to AWS. Amazon FSx is a service that provides fully managed file storage for Windows and Linux applications. Amazon FSx does not provide a central data protection policy, but rather offers features such as encryption, snapshots, backups, and replication to protect your file systems.

• Question 407:

  A company has a global website with static content.

  Which AWS service will deliver the static content with low latency?

  A. AWS Lambda
  B. Amazon CloudFront
  C. Amazon EC2 Auto Scaling
  D. AWS Compute Optimizer

• Question 408:

  A company needs to use AWS technology to deploy a static website.

  Which solution meets this requirement with the LEAST amount of operational overhead?

  A. Deploy the website on Amazon EC2.
  B. Host the website on AWS Elastic Beanstalk.
  C. Deploy the website with Amazon Lightsail.
  D. Host the website on Amazon S3.
  D. Host the website on Amazon S3.

  ---

  Explanation

  Amazon S3 (Simple Storage Service) is ideal for hosting static websites with minimal operational overhead. It allows you to store and serve static content (like HTML, CSS, and JavaScript files) directly from S3 buckets without needing to manage any servers or complex infrastructure. Additionally, Amazon S3 is highly scalable, cost-effective, and requires very little maintenance.

• Question 409:

  A company has a MySQL database running on a single Amazon EC2 instance. The company now requires higher availability in the event of an outage.

  Which set of tasks would meet this requirement?

  A. Add an Application Load Balancer in front of the EC2 instance.
  B. Configure EC2 Auto Recovery to move the instance to another Availability Zone.
  C. Migrate to Amazon RDS and enable Multi-AZ.
  D. Enable termination protection for the EC2 instance to avoid outages.
  C. Migrate to Amazon RDS and enable Multi-AZ.

  ---

  Explanation

  The set of tasks that would meet the requirement of having higher availability for a MySQL database running on a single Amazon EC2 instance is to migrate to Amazon RDS and enable Multi-AZ. Amazon RDS is a fully managed relational database service that supports MySQL and other popular database engines. By enabling Multi-AZ, users can have a primary database in one Availability Zone and a synchronous standby replica in another Availability Zone. In case of a planned or unplanned outage of the primary database, Amazon RDS automatically fails over to the standby replica with minimal disruption3. Adding an Application Load Balancer in front of the EC2 instance, configuring EC2 Auto Recovery to move the instance to another Availability Zone, or enabling termination protection for the EC2 instance would not provide higher availability for the database, as they do not address the single point of failure or data replication issues.

• Question 410:

  A company wants to estimate the cost for its AWS architecture solution before migration. Which AWS service or feature will meet this requirement?

  A. Amazon Detective
  B. AWS Budgets
  C. AWS Resource Explorer
  D. AWS Pricing Calculator
  D. AWS Pricing Calculator
