A company needs to store infrequently used data for data archives and long-term backups.
Which AWS service or storage class will meet these requirements MOST cost-effectively?
Amazon S3 Glacier Flexible Retrieval is optimized for storing infrequently accessed data at a very low cost, making it suitable for data archiving and long-term backups. It provides flexible retrieval options for archived data. Other services like FSx for Lustre, EBS, and EFS are more suited for frequently accessed data and higher-performance use cases, not archival storage.
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 requirement?
AWS Enterprise Support provides strategic planning assistance, infrastructure event management, and real-time support, which are necessary for business-critical applications. Trusted Advisor and APN do not offer direct strategic support, and while AWS Professional Services can assist with complex solutions, Enterprise Support specifically includes ongoing operational support and event management.
Which AWS Cloud design principle is a company using when the company implements AWS CloudTrail?
By implementing AWS CloudTrail, a company is adhering to the AWS Cloud design principle of activating traceability. AWS CloudTrail provides detailed logs of all API calls made in an AWS account, which helps monitor, troubleshoot, and detect unusual activity, thereby improving security and compliance. This supports the principle of 'activating traceability' by enabling continuous monitoring and auditing of all actions and changes within the AWS environment.
B . Use serverless compute architectures: Incorrect, as this principle encourages the use of managed services that handle infrastructure, such as AWS Lambda, and is not directly related to CloudTrail.
C . Perform operations as code: Incorrect, as this principle emphasizes the use of code and automation for infrastructure management.
D . Go global in minutes: Incorrect, as this principle relates to the global deployment of applications and services.

A company stores data in an Amazon S3 bucket.
Which task is the responsibility of AWS?
According to the AWS Shared Responsibility Model, AWS is responsible for protecting the infrastructure that runs all of the services offered in the AWS Cloud, including Amazon S3. This infrastructure includes hardware, software, networking, and facilities that run AWS services.
A . Configure an S3 Lifecycle policy: Incorrect, as configuring S3 Lifecycle policies to manage object lifecycle (e.g., transitioning objects to different storage classes or deleting them after a certain period) is the customer's responsibility.
B . Activate S3 Versioning: Incorrect, as enabling S3 Versioning is a customer responsibility for managing data protection.
C . Configure S3 bucket policies: Incorrect, as setting and managing S3 bucket policies to control access is the customer's responsibility.

A company is building a new application on AWS. The company needs the application to remain available if an individual application component fails.
Which design principle should the company use to meet this requirement?
Loose coupling is a design principle that involves reducing dependencies between application components so that they can operate independently. This approach ensures that the failure of one component does not affect the availability of the others, thereby improving the application's fault tolerance and resilience. Disposable resources, automation, and rightsizing are valuable principles in cloud architecture, but they do not directly address the requirement of remaining available despite the failure of an individual component like loose coupling does.
