問題 #828
A company wants to ensure that two Amazon EC2 instances are in separate data centers with minimal communication latency between the data centers.
How can the company meet this requirement?

答案：D

解題說明：
Explanation
The correct answer is B because placing the EC2 instances in two separate Availability Zones within the same AWS Region is the best way to meet the requirement. Availability Zones are isolated locations within an AWS Region that have independent power, cooling, and networking. Users can launch their resources, such as Amazon EC2 instances, in multiple Availability Zones to increase the fault tolerance and resilience of their applications. Availability Zones within the same AWS Region are connected with low-latency, high-throughput, and highly redundant networking. The other options are incorrect because they are not the best ways to meet the requirement. Placing the EC2 instances in two separate AWS Regions connected with a VPC peering connection is not the best way to meet the requirement because AWS Regions are geographically dispersed and may have higher communication latency between them than Availability Zones within the same AWS Region. VPC peering connection is a networking connection between two VPCs that enables users to route traffic between them using private IP addresses. Placing one EC2 instance on premises and the other in an AWS Region, and then connecting them by using an AWS VPN connection is not the best way to meet the requirement because on-premises and AWS Region are geographically dispersed and may have higher communication latency between them than Availability Zones within the same AWS Region. AWS VPN connection is a secure and encrypted connection between a user's network and their VPC. Placing both EC2 instances in a placement group for dedicated bandwidth is not the best way to meet the requirement because a placement group is a logical grouping of instances within a single Availability Zone that enables users to launch instances with specific performance characteristics. A placement group does not ensure that the instances are in separate data centers, and it does not provide low-latency communication between instances in different Availability Zones.

問題 #829
Which AWS service requires the customer to patch the guest operating system?

答案：B

解題說明：
Explanation
The AWS service that requires the customer to patch the guest operating system is Amazon EC2. Amazon EC2 is a service that provides scalable compute capacity in the cloud, and allows customers to launch and run virtual servers, called instances, with a variety of operating systems, configurations, and specifications. The customer is responsible for patching and updating the guest operating system and any applications that run on the EC2 instances, as part of the security in the cloud. AWS Lambda, Amazon OpenSearch Service, and Amazon ElastiCache are not services that require the customer to patch the guest operating system. AWS Lambda is a serverless compute service that allows customers to run code without provisioning or managing servers. Amazon OpenSearch Service is a fully managed service that makes it easy to deploy, operate, and scale OpenSearch clusters in the AWS Cloud. Amazon ElastiCache is a fully managed service that provides in-memory data store and cache solutions, such as Redis and Memcached. These services are managed by AWS, and AWS is responsible for patching and updating the underlying infrastructure and software.


問題 #830
Which of the following are customer responsibilities under the AWS shared responsibility model? (Select TWO.)

答案：B,C

解題說明：
Explanation
The AWS shared responsibility model describes how AWS and the customer share responsibility for security and compliance of the AWS environment. AWS is responsible for the security of the cloud, which includes the physical security of AWS facilities, the infrastructure, hardware, software, and networking that run AWS services. The customer is responsible for security in the cloud, which includes the configuration of security groups, the encryption of customer data on AWS, the management of AWS Lambda infrastructure, and the management of network throughput of each AWS Region.


問題 #831
To reduce costs, a company is planning to migrate a NoSQL database to AWS.
Which AWS service is fully managed and can automatically scale throughput capacity to meet database workload demands?

答案：B

解題說明：
Amazon DynamoDB is a fully managed, serverless, key-value NoSQL database service that can deliver consistent, single-digit millisecond performance at any scale. DynamoDB can automatically scale throughput capacity to meet the demands of the database workload, without requiring any manual intervention.
DynamoDB is ideal for NoSQL applications that need high performance, availability, and scalability.
DynamoDB also offers features such as encryption at rest, point-in-time recovery, global tables, and in-memory caching. References: What is NoSQL?, Amazon DynamoDB, [AWS Cloud Practitioner Essentials:
Module 4 - Databases in the Cloud]


問題 #832
A company deploys its application to multiple AWS Regions and configures automatic failover between those Regions.
Which cloud concept does this architecture represent?

答案：C

解題說明：
Explanation
Reliability is the cloud concept that this architecture represents. Reliability is the ability of a system to recover from infrastructure or service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues. Deploying an application to multiple AWS Regions and configuring automatic failover between those Regions enhances the reliability of the application by reducing the impact of regional failures and increasing the availability of the application4
