 EFS Standard-Infrequent Access (EFS Standard-IA) is the storage class that meets the requirements of storing data across multiple Availability Zones in an AWS Region, that will not be accessed regularly but must be immediately retrievable, most cost-effectively. EFS Standard-IA is designed for files that are accessed less frequently, but still require the same high performance, low latency, and high availability as EFS Standard. EFS Standard-IA has a lower storage cost than EFS Standard, but charges a small additional fee for each access. EFS One Zone and EFS One Zone-IA store data in a single Availability Zone, which reduces the availability and durability compared to EFS Standard and EFS Standard-IA.

 AWS CloudFormation is a service that gives developers and businesses an easy way to create a collection of related AWS and third-party resources, and provision and manage them in an orderly and predictable fashion. You can use AWS CloudFormation’s sample templates or create your own templates to describe the AWS and third-party resources, and any associated dependencies or runtime parameters, required to run your application.

 Amazon CloudFront is the AWS service that offers a global content delivery network (CDN) that helps companies securely deliver websites, videos, applications, and APIs at high speeds with low latency. Amazon CloudFront is a web service that speeds up distribution of static and dynamic web content, such as HTML, CSS, JavaScript, and image files, to users. Amazon CloudFront uses a global network of edge locations, located near users’ geographic locations, to cache and serve content with high availability and performance. Amazon CloudFront also provides features such as AWS Shield for DDoS protection, AWS Certificate Manager for SSL/TLS encryption, AWS WAF for web application firewall, and AWS Lambda@Edge for customizing content delivery with serverless code. Amazon EC2, Amazon CloudWatch, and AWS CloudFormation are not services that offer a global CDN. Amazon EC2 is a service that provides scalable compute capacity in the cloud. Amazon CloudWatch is a service that provides monitoring and observability for AWS resources andapplications. AWS CloudFormation is a service that provides a common language to model and provision AWS resources and their dependencies.

AWS Storage Gateway Volume Gateway, specifically its cached-volume configuration, meets the stated hybrid-storage requirements. With cached volumes, the primary data is stored in Amazon S3 while frequently accessed data is retained locally in the gateway’s cache. On-premises application servers access the volumes through the iSCSI protocol, and the local cache provides low-latency access to the active working set. This design allows the company to move or extend storage into AWS without requiring every frequently used block to be retrieved across the network for each access. Therefore, option C is correct. AWS Database Migration Service migrates and replicates database data, but the question describes application storage data and persistent low-latency access rather than a database-engine migration. AWS Application Migration Service moves servers and applications to AWS and is not a hybrid block-storage caching service. AWS Direct Connect provides a dedicated network connection between an on-premises environment and AWS, but connectivity alone does not create local caching for frequently used data. The decisive phrases are “application data” and “low-latency access to frequently used data,” which align directly with Volume Gateway cached volumes.

AWS SDKs Overview:

AWS Software Development Kits (SDKs) provide libraries and tools for developers to interact with AWS services programmatically.

SDKs are available for multiple programming languages, including Python, Java, JavaScript, and .NET.

How AWS SDKs Meet the Requirement:

Enable developers to integrate AWS services into their applications easily.

Include API clients, authentication helpers, and other utilities specific to AWS services.

Why Other Options Are Incorrect:

A. AWS CodePipeline:Automates CI/CD pipelines but does not provide libraries for development.

C. Amazon CloudWatch:Focuses on monitoring and logging; not a development toolset.

D. AWS CodeDeploy:Automates application deployment but does not include development libraries.

Comprehensive and Detailed Explanation From AWS Cloud Documentation:

Only the AWS account root user can create or delete access keys that belong to that root user. AWS documentation for creating root-user access keys requires signing in with root-user credentials and explicitly states that the procedure cannot be performed as an IAM user or IAM role. Therefore, option A is correct when “AWS account owner” is understood as the person signing in as the AWS account root user. Administrator permissions attached to an IAM user, an IAM group, or an administrator group do not convert that IAM identity into the root user and do not authorize it to manage root-user access keys. Root-user access keys are long-term credentials with unrestricted account power, including access to AWS resources and billing information. AWS strongly recommends not creating them. For programmatic access, the safer practice is to use temporary credentials through IAM roles, IAM Identity Center, or another appropriately scoped identity. Root credentials should be protected with multi-factor authentication and used only for tasks that specifically require them. Thus, none of the IAM-user options is valid.
