• Question 832:

  A company wants to design a reliable web application that is hosted on Amazon EC2. Which approach will achieve this goal?

  A. Launch large EC2 instances in the same Availability Zone.
  B. Spread EC2 instances across more than one security group.
  C. Spread EC2 instances across more than one Availability Zone.
  D. Use an Amazon Machine Image (AMI) from AWS Marketplace.
  C. Spread EC2 instances across more than one Availability Zone.

  ---

  Explanation

  The approach that will achieve the goal of designing a reliable web application that is hosted on Amazon EC2 is to spread EC2 instances across more than one Availability Zone. An Availability Zone is a physically isolated location within an AWS Region that has its own power, cooling, and network connectivity. By spreading EC2 instances across multiple Availability Zones, users can increase the fault tolerance and availability of their web applications, as well as reduce latency for end users2. Launching large EC2 instances in the same Availability Zone, spreading EC2 instances across more than one security group, or using an Amazon Machine Image (AMI) from AWS Marketplace are not sufficient to ensure reliability, as they do not provide redundancy or resilience in case of an outage in one Availability Zone.

• Question 833:

  Which AWS service provides storage-optimized and compute-optimized device configurations?

  A. AWS Snowcone
  B. AWS Storage Gateway
  C. AWS Snowball Edge
  D. AWS DataSync
  C. AWS Snowball Edge

  ---

  Explanation

  AWS Snowball Edge offers configurations that are either storage-optimized or compute-optimized, providing flexibility for different data migration and processing needs. It supports local processing and data transfer to AWS, catering to scenarios that require heavy storage or compute resources. AWS Snowcone and DataSync do not offer these optimizations, and Storage Gateway focuses on hybrid cloud storage.

• Question 834:

  Which guideline is a well-architected design principle for building cloud applications?

  A. Keep static data closer to compute resources.
  B. Provision resources for peak capacity.
  C. Design for automated recovery from failure.
  D. Use tightly coupled components.
  C. Design for automated recovery from failure.

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

• Question 837:

  Which benefit of AWS Cloud computing provides lower latency between users and applications?

  A. Agility
  B. Economies of scale
  C. Global reach
  D. Pay-as-you-go pricing
  C. Global reach

  ---

  Explanation

  Global reach is the benefit of AWS Cloud computing that provides lower latency between users and applications. Global reach means that AWS customers can deploy their applications and data in multiple regions around the world, and deliver them to users with high performance and availability. AWS has the largest global infrastructure of any cloud provider, with 25 geographic regions and 81 Availability Zones, as well as 216 Points of Presence in 84 cities across 42 countries. Customers can choose the optimal locations for their applications and data based on their business requirements, such as compliance, data sovereignty, and customer proximity. Agility, economies of scale, and pay-as-you-go pricing are other benefits of AWS Cloud computing, but they do not directly provide lower latency between users and applications. Agility means that AWS customers can quickly and easily provision and scale up or down AWS resources as needed, without upfront costs or long-term commitments. Economies of scale means that AWS customers can benefit from the lower costs and higher efficiency that AWS achieves by operating at a massive scale and passing the savings to the customers. Pay-as-you-go pricing means that AWS customers only pay for the AWS resources they use, without any upfront costs or long-term contracts.

• Question 838:

  A company is reviewing its operating policies.

  Which policy complies with guidance in the security pillar of the AWS Well-Architected Framework?

  A. Ensure that employees have access to all company data.
  B. Expand employees' permissions as they gain more experience.
  C. Grant all privileges and access to all users.
  D. Apply security requirements at all layers of a process.
  D. Apply security requirements at all layers of a process.

  ---

  Explanation

  Applying security requirements at all layers of a process is a policy that complies with guidance in the security pillar of the AWS Well-Architected Framework. The security pillar of the AWS Well-Architected Framework provides best practices for securing the user's data and systems in the AWS Cloud. One of the design principles of the security pillar is to apply security at all layers, which means that the user should implement defense-in-depth strategies and avoid relying on a single security mechanism. For example, the user should use multiple security controls, such as encryption, firewalls, identity and access management, and logging and monitoring, to protect their data and resources at different layers.

• Question 839:

  A company has refined its workload to use specific AWS services to improve efficiency and reduce cost. Which task is a customer's responsibility, according to the AWS shared responsibility model?

  A. Management of the guest operating systems
  B. Maintenance of the configuration of infrastructure devices
  C. Management of the host operating systems and virtualization
  D. Maintenance of the software that powers Availability Zones
  A. Management of the guest operating systems

  ---

  Explanation

  Management of the guest operating systems is a customer's responsibility, according to the AWS shared responsibility model. The AWS shared responsibility model defines the different security and compliance responsibilities of AWS and the customer. AWS is responsible for the security of the cloud, which includes the physical infrastructure, hardware, software, and facilities that run the AWS Cloud. The customer is responsible for security in the cloud, which includes the configuration and management of the guest operating systems, applications, data, and network traffic protection

• Question 840:

  A company's IT team is managing MySQL database server clusters. The IT team has to patch the database and take backup snapshots of the data in the clusters. The company wants to move this workload to AWS so that these tasks will be completed automatically.

  What should the company do to meet these requirements?

  A. Deploy MySQL database server clusters on Amazon EC2 instances.
  B. Use Amazon RDS with a MySQL database.
  C. Use an AWS CloudFormation template to deploy MySQL database servers on Amazon EC2 instances.
  D. Migrate all the MySQL database data to Amazon S3.
  B. Use Amazon RDS with a MySQL database.

  ---

  Explanation

  Amazon RDS is a service that makes it easy to set up, operate, and scale a relational database in the cloud. Amazon RDS supports MySQL as one of the database engines. By using Amazon RDS with a MySQL database, the company can offload the tasks of patching the database and taking backup snapshots to AWS. Amazon RDS automatically patches the database software and operating system of the database instances. Amazon RDS also automatically backs up the database and retains the backups for a user-defined retention period. The company can also restore the database to any point in time within the retention period. Deploying MySQL database server clusters on Amazon EC2 instances, using an AWS CloudFormation template to deploy MySQL database servers on Amazon EC2 instances, or migrating all the MySQL database data to Amazon S3 are not the best options to meet the requirements. These options would not automate the tasks of patching the database and taking backup snapshots, and would require more operational overhead from the company3
