• Question 761:

  A company wants to migrate its on-premises relational databases to the AWS Cloud. The company wants to use infrastructure as close to its current geographical location as possible.

  Which AWS service or resource should the company use to select its Amazon RDS deployment area?

  A. Amazon Connect
  B. AWS Wavelength
  C. AWS Regions
  D. AWS Direct Connect
  C. AWS Regions

  ---

  Explanation

  AWS Regions are the AWS service or resource that the company should use to select its Amazon RDS deployment area. AWS Regions are separate geographic areas where AWS clusters its data centers. Each AWS Region consists of multiple, isolated, and physically separate Availability Zones within a geographic area. Each AWS Region is designed to be isolated from the other AWS Regions to achieve the highest possible fault tolerance and stability. AWS provides a more extensive global footprint than any other cloud provider, and to support its global footprint and ensure customers are served across the world, AWS opens new Regions rapidly. AWS maintains multiple geographic Regions, including Regions in North America, South America, Europe, China, Asia Pacific, South Africa, and the Middle East. Amazon RDS is available in several AWS Regions worldwide. To create or work with an Amazon RDS DB instance in a specific AWS Region, you must use the corresponding regional service endpoint. You can choose the AWS Region that meets your latency or legal requirements. You can also use multiple AWS Regions to design a disaster recovery solution or to distribute your read workload.

• Question 764:

  Which of the following is an advantage that users experience when they move on-premises workloads to the AWS Cloud?

  A. Elimination of expenses for running and maintaining data centers
  B. Price discounts that are identical to discounts from hardware providers
  C. Distribution of all operational controls to AWS
  D. Elimination of operational expenses
  A. Elimination of expenses for running and maintaining data centers

  ---

  Explanation

  The advantage that users experience when they move on-premises workloads to the AWS Cloud is: elimination of expenses for running and maintaining data centers. By moving on-premises workloads to the AWS Cloud, users can reduce or eliminate the costs associated with owning and operating physical servers, storage, network equipment, and facilities. These costs include hardware purchase, maintenance, repair, power, cooling, security, and staff. Users can also benefit from the pay-as-you-go pricing model of AWS, which allows them to pay only for the resources they use, and scale up or down as needed.

• Question 765:

  Which of the following is the customer's responsibility, according to the AWS shared responsibility model?

  A. Identity and access management
  B. Hard drive initialization
  C. Protection of data center hardware
  D. Security of Availability Zones
  A. Identity and access management

  ---

  Explanation

  Identity and access management is the customer's responsibility, according to the AWS shared responsibility model. This means that the customer is responsible for managing user access to the AWS resources, using tools such as AWS Identity and Access Management (IAM), AWS Single Sign-On (SSO), and AWS Organizations. The customer is also responsible for securing their data in transit and at rest, using encryption, key management, and other methods. Hard drive initialization, protection of data center hardware, and security of Availability Zones are AWS's responsibility, as they are part of the infrastructure, physical security, and network security that AWS provides to the customer12

• Question 766:

  A company must store call recordings for 6 years. The storage system should be highly durable and cost-effective.

  Which AWS service meets these requirements?

  A. AWS Snowball
  B. Amazon S3
  C. AWS Storage Gateway
  D. Amazon Kinesis
  B. Amazon S3

  ---

  Explanation

  Amazon S3 is a service that provides highly durable and cost-effective object storage for a variety of use cases, including backup and archive, big data analytics, disaster recovery, and cloud applications. Amazon S3 offers 99.999999999% (11 nines) of durability, meaning that data is designed to withstand the loss of two facilities concurrently. Amazon S3 also offers several storage classes with different price and performance characteristics, such as S3 Glacier and S3 Glacier Deep Archive, which are ideal for long- term archival of data that is rarely accessed. AWS Snowball, AWS Storage Gateway, and Amazon Kinesis are not designed to provide the same level of durability and cost- effectiveness as Amazon S3 for storing call recordings for 6 years.

  Explanation

  AWS performs some tasks automatically to help you manage and secure your AWS resources. One of these tasks is patching Amazon EC2 instances. AWS provides two options for patching your EC2 instances: managed instances and patch baselines. Managed instances are a group of EC2 instances or on-premises servers that you can manage using AWS Systems Manager. Patch baselines define the patches that AWS Systems Manager applies to your instances. You can use AWS Systems Manager to automate the process of patching your instances based on a schedule or a maintenance window.
