  A. AWS Basic Support
  B. AWS Business Support
  C. AWS Developer Support
  D. AWS Enterprise Supportd
  C. AWS Developer Support

  A. Patching the guest operating system
  B. Maintaining physical and environmental controls
  C. Protecting communications and maintaining zone security
  D. Patching specific applications
  B. Maintaining physical and environmental controls

• Question 1054:

  A company is building a web application and needs to test the application across different mobile devices and desktop browsers Which AWS service should the company use for this testing?

  A. AWS Amplify
  B. AWS AppSync
  C. Amazon Pinpoint
  D. AWS Device Farm
  D. AWS Device Farm

• Question 1055:

  A company wants to migrate its main application to Amazon EC2. The application must provide low latency to users residing in two different geographic locations. The architecture of the application must have disaster recovery capabilities. How can these requirements be met?

  A. Deploy the application on an EC2 instance and set up EC2 automatic recovery
  B. Deploy the application on multiple EC2 instances running in one Availability Zone
  C. Deploy the application on EC2 instances in Multi-AZs in a single AWS Region
  D. Deploy the application on EC2 instances in multiple AWS Regions.
  D. Deploy the application on EC2 instances in multiple AWS Regions.

  ---

  Explanation/Reference:

  The correct answer is D. Deploy the application on EC2 instances in multiple AWS Regions.

  To meet the requirements of providing low latency to users in two different geographic locations and having disaster recovery capabilities, the application should be deployed on EC2 instances in multiple AWS regions. This architecture provides high availability and disaster recovery capabilities by replicating data and services across multiple regions. If one region becomes unavailable, the application can be quickly switched to another region without disrupting end-users.

• Question 1056:

  A company needs an AWS design solution for a distributed system. The system's components need to be set up so that one system component cannot negatively impact another component. Which AWS architectural best practice will meet this requirement?

  A. Use request throttling
  B. Use a stateful service
  C. Implement automatic data backups
  D. Implement loose coupling
  D. Implement loose coupling

  ---

  Explanation/Reference:

  D. Implement loose coupling

  Implementing loose coupling is an architectural best practice that helps to prevent one system component from negatively impacting another component. Loose coupling is achieved by designing the system so that each component is independent of the others and only communicates with them through a well-defined interface. This allows changes to be made to one component without affecting the others, and also allows the system to be more resilient to failures. When components are loosely coupled, it's easier to scale, maintain, and update the system, as well as to troubleshoot issues.

  Use request throttling is a technique to control the rate of incoming requests to a service, avoiding overloading it, but it does not prevent one component from impacting another.

  A stateful service is one that maintains state information across requests, which could cause issues if not properly managed. Implementing automatic data backups is a security best practice, but it doesn't prevent one component from impacting another.

• Question 1057:

  A company plans to run its IT infrastructure in the AWS Cloud. The infrastructure must be highly available. The company also must minimize the network latency between servers. Which deployment scenario will meet these requirements?

  A. Deploy in multiple Availability Zones in multiple AWS Regions.
  B. Deploy in one Availability Zone in one AWS Region
  C. Deploy in multiple AWS Regions. Deploy in one Availability Zone in each Region.
  D. Deploy in multiple Availability Zones in one AWS Region.
  D. Deploy in multiple Availability Zones in one AWS Region.

  ---

  Explanation/Reference:

  The infrastructure must be highly available. Should the compamy use multiple Availability Zones. The company also must minimize the network latency between servers. should be in one AWS Region.

• Question 1058:

  Which of the following is an important architectural design principle when designing cloud applications?

  A. Use multiple Availability Zones.
  B. Use tightly coupled components.
  C. Use open source software.
  D. Provision extra capacity.
  A. Use multiple Availability Zones.

  ---

  Explanation/Reference:

  Data Center resilience is practiced through Availability Zones across data centers that reduce the impact of failures.

  Fault isolation improvement can be made to traditional horizontal scaling by sharding (a method of grouping instances into groups called shards, instead of sending the traffic from all users to every node like in the traditional IT structure.)

• Question 1059:

  A batch workload takes 5 hours to finish on an Amazon EC2 instance. The amount of data to be processed doubles monthly and the processing time is proportional. What is the best cloud architecture to address this consistently growing demand?

  A. Run the application on a bigger EC2 instance size.
  B. Switch to an EC2 instance family that better matches batch requirements.
  C. Distribute the application across multiple EC2 instances and run the workload in parallel.
  D. Run the application on a bare metal EC2 instance.
  C. Distribute the application across multiple EC2 instances and run the workload in parallel.

• Question 1060:

  Under the AWS shared responsibility model, AWS is responsible for which security-related task?

  A. Lifecycle management of IAM credentials
  B. Physical security of global infrastructure
  C. Encryption of Amazon EBS volumes
  D. Firewall configuration
  B. Physical security of global infrastructure
