Question 136

A company is migrating its workloads to AWS. The company has sensitive and critical data in on-premises relational databases that run on SQL Server instances. The company wants to use the AWS Cloud to increase security and reduce operational overhead for the databases. Which solution will meet these requirements?

Options:

Migrate the databases to Amazon EC2 instances. Use an AWS Key Management Service (AWS KMS) AWS managed key for encryption.

Migrate the databases to a Multi-AZ Amazon RDS for SQL Server DB instance Use an AWS Key Management Service (AWS KMS) AWS managed key for encryption.

Migrate the data to an Amazon S3 bucket Use Amazon Macie to ensure data security

Migrate the databases to an Amazon DynamoDB table. Use Amazon CloudWatch Logs to ensure data security

Question 137

Asocial media company has workloads that collect and process data The workloads store the data in on-premises NFS storage The data store cannot scale fast enough to meet the company's expanding business needs The company wants to migrate the current data store to AWS

Which solution will meet these requirements MOST cost-effectively?

Options:

Set up an AWS Storage Gateway Volume Gateway Use an Amazon S3 Lifecycle policy to transition the data to the appropnate storage class

Set up an AWS Storage Gateway Amazon S3 File Gateway Use an Amazon S3 Lifecycle policy to transition the data to the appropriate storage class

Use the Amazon Elastic File System (Amazon EFS) Standard-Infrequent Access (Standard-IA) storage class Activate the infrequent access lifecycle policy

Use the Amazon Elastic File System (Amazon EFS) One Zone-Infrequent Access (One Zone-IA) storage class Activate the infrequent access lifecycle policy

Answer:

Explanation:

This solution meets the requirements most cost-effectively because it enables the company to migrate its on-premises NFS data store to AWS without changing the existing applications or workflows. AWS Storage Gateway is a hybrid cloud storage service that provides seamless and secure integration between on-premises and AWS storage. Amazon S3 File Gateway is a type of AWS Storage Gateway that provides a file interface to Amazon S3, with local caching for low-latency access. By setting up an Amazon S3 File Gateway, the company can store and retrieve files as objects in Amazon S3 using standard file protocols such as NFS. The company can also use an Amazon S3 Lifecycle policy to automatically transition the data to the appropriate storage class based on the frequency of access and the cost of storage. For example, the company can use S3 Standard for frequently accessed data, S3 Standard-Infrequent Access (S3 Standard-IA) or S3 One Zone-Infrequent Access (S3 One Zone-IA) for less frequently accessed data, and S3 Glacier or S3 Glacier Deep Archive for long-term archival data.

Option A is not a valid solution because AWS Storage Gateway Volume Gateway is a type of AWS Storage Gateway that provides a block interface to Amazon S3, with local caching for low-latency access. Volume Gateway is not suitable for migrating an NFS data store, as it requires attaching the volumes to EC2 instances or on-premises servers using the iSCSI protocol. Option C is not a valid solution because Amazon Elastic File System (Amazon EFS) is a fully managed elastic NFS file system that is designed for workloads that require high availability, scalability, and performance. Amazon EFS Standard-Infrequent Access (Standard-IA) is a storage class within Amazon EFS that is optimized for infrequently accessed files, with a lower price per GB and a higher price per access. Using Amazon EFS Standard-IA for migrating an NFS data store would not be cost-effective, as it would incur higher access charges and require additional configuration to enable lifecycle management. Option D is not a valid solution because Amazon EFS One Zone-Infrequent Access (One Zone-IA) is a storage class within Amazon EFS that is optimized for infrequently accessed files that do not require the availability and durability of Amazon EFS Standard or Standard-IA. Amazon EFS One Zone-IA stores data in a single Availability Zone, which reduces the cost by 47% compared to Amazon EFS Standard-IA, but also increases the risk of data loss in the event of an Availability Zone failure. Using Amazon EFS One Zone-IA for migrating an NFS data store would not be cost-effective, as it would incur higher access charges and require additional configuration to enable lifecycle management. It would also compromise the availability and durability of the data.

Question 139

A company wants to build a logging solution for its multiple AWS accounts. The company currently stores the logs from all accounts in a centralized account. The company has created an Amazon S3 bucket in the centralized account to store the VPC flow logs and AWS CloudTrail logs. All logs must be highly available for 30 days for frequent analysis, retained tor an additional 60 days tor backup purposes, and deleted 90 days after creation.

Which solution will meet these requirements MOST cost-effectively?

Options:

Transition objects to the S3 Standard storage class 30 days after creation. Write an expiration action that directs Amazon S3 to delete objects after 90 days.

Transition objects lo the S3 Standard-Infrequent Access (S3 Standard-IA) storage class 30 days after creation Move all objects to the S3 Glacier Flexible

Retrieval storage class after 90 days. Write an expiration action that directs Amazon S3 to delete objects after 90 days.

Transition objects to the S3 Glacier Flexible Retrieval storage class 30 days after creation. Write an expiration action that directs Amazon S3 to delete objects alter 90 days.

Transition objects to the S3 One Zone-Infrequent Access (S3 One Zone-IA) storage class 30 days after creation. Move all objects to the S3 Glacier Flexible Retrieval storage class after 90 days. Write an expiration action that directs Amazon S3 to delete objects after 90 days.
