A Cloud Practitioner has been asked to increase the availability of the database so there is automatic recovery in the case of a failure.Which tasks can the Cloud Practitioner take to meet this requirement?

• Migrate the database to Amazon RDS and enable the Multi-AZ feature
• Configure an Elastic Load Balancer in front of the EC2 instance
• Configure EC2 Auto Recovery to move the instance to another Region
• Set the DeleteOnTermination value to false for the EBS root volume

Answer:

• Moving the database to Amazon RDS means that the database can take advantage of the built-in

Multi-AZ feature. This feature creates a standby instance in another Availability Zone and synchronously replicates to it. In the event of a failure that affects the primary database an automatic failover can occur and the database will become functional on the standby instance."Configure an Elastic Load Balancer in front of the EC2 instance" is incorrect. You cannot use an ELB to distribute traffic to a database and with a single instance there's no benefit here at all."Configure EC2 Auto Recovery to move the instance to another Region" is incorrect. The auto recovery feature of EC2 automatically moves the instance to another host, not to another Region."Set the DeleteOnTermination value to false for the EBS root volume" is incorrect. This will simply preserve the root volume; it will not perform automatic recovery

Question 2: Which AWS AI services allows to build, train, and deploy your own ML models without worrying about infrastructure?

• Amazon Bedrock
• Amazon Q Business
• Amazon SageMaker AI
• Amazon Q Developer

Answer:

• Amazon SageMaker AI

"Amazon Bedrock" is used to fine-tune and seamlessly integrate large Foundation Models from Amazon and leading AI startups into your AWS applications with a single API (Gen AI) "Amazon Q Business" is used to answer questions and solve problems using the data and expertise found in your company's information repositories."Amazon Q Developer" accelerates developments with code recommendations.Question 3: Which of the following is defined as a scalable block storage service that provides persistent, high-performance volumes you can attach to your EC2 instances for data storage and applications ?

• EC2 Instance Store
• Amazon Elastic Block Store
• EBS Snapshots
• Amazon S3

Answer:

• Amazon Elastic Block Store

"An EC2 Instance store" is a temporary storage option that is directly attached to the host computer of an EC2 instance "EBS Snapshots" are point-in-time backups of your cloud storage volumes, making it possible to protect data and restore it when needed."S3" is a scalable cloud object storage service that can store and retrieve any amount of data from anywhere on the web.

Question 4: A company needs to publish messages to a thousands of subscribers

simultaneously using a push mechanism.Which AWS service should the company use?

• Amazon Simple Queue Service (Amazon SQS)
• Amazon Simple Notification Service (Amazon SNS)
• Amazon Simple Workflow Service (SWF)
• AWS Step Functions

Answer:

• Amazon SNS is a publisher/subscriber notification service that uses a push mechanism to publish

messages to multiple subscribers. Amazon SNS enables you to send messages or notifications directly to users with SMS text messages to over 200 countries, mobile push on Apple, Android, and other platforms or email (SMTP).

Question 5: For what purpose would a Cloud Practitioner access AWS Artifact?

• Create AWS AMI Images
• Gain access to AWS security and compliance documents
• Organise all backup solutions across the AWS landscape
• Deploy ML models without having to manage the infrastructure

Answer:

• Gain access to AWS security and compliance documents

Question 6: A user is planning to launch three EC2 instances behind a single Elastic Load Balancer. The deployment should be highly available.How should the user achieve this?

• Launch the instances as EC2 Spot Instances in the same AWS Region and the same

Availability Zone

• Launch the instances in multiple AWS Regions, and use Elastic IP addresses
• Launch the instances as EC2 Reserved Instances in the same AWS Region, but in different

Availability Zones

• Launch the instances across multiple Availability Zones in a single AWS Region

Answer:

• Launch the instances across multiple AZ in a single AWS Region

To make the deployment highly available the user should launch the instances across multiple Availability Zones in a single AWS Region. Elastic Load Balancers can only serve targets in a single Region so it is not possible to deploy across Regions.The other answers are incorrect

• The pricing model is not relevant to high availability and deploying in a single AZ does not result in a

highly available deployment.

• You cannot use an ELB with instances in multiple Regions and using an EIP does not help.
• Using reserved instances may not be appropriate as we do not know whether this is going to be a

long-term workload or not.Question 7: Which part of an Amazon VPC can be defined as a section of a VPC that can contain resources and is used to organize your resources?

• An Internet Gateway
• A Virtual Private Gateway
• A Subnet
• AWS Client VPN

Answer:

• A Subnet is a section of a VPC that can contain resources and is used to organize your resources.

They can contain be either public or private."An internet Gateway" is a connection between a VPC and the internet. It allows public traffic from the internet to access your VPC."A virtual private gateway" is the component that allows protected internet traffic to enter into the VPC. It allows a connection between your VPC and a private network only if it is coming from an approved network."Amazon Client VPC" is a networking service you can use to connect your remote workers and on-premises networks to the cloud. It is a fully managed, elastic VPN service that automatically scales up or down based on user demand Question 8: A company has multiple AWS accounts and is using AWS Organizations with consolidated billing. Which advantages will they benefit from? (Select TWO.)

• They will be automatically enrolled in a business support plan
• They may benefit from lower unit pricing for aggregated usage
• The default service limits in all accounts will be increased
