A company's application on EC2 instances relies on a Single-AZ RDS for MySQL DB instance. The SysOps administrator needs to ensure failover to minimize downtime.
A SysOps administrator creates two VPCs, VPC1 and VPC2, in a company's AWS account The SysOps administrator deploys a Linux Amazon EC2 instance in VPC1 and deploys an Amazon RDS for MySQL DB instance in VPC2. The DB instance is deployed in a private subnet. An application that runs on the EC2 instance needs to connect to the database. What should the SysOps administrator do to give the EC2 instance the ability to connect to the database?
A company needs to monitor the disk utilization of Amazon Elastic Block Store (Amazon EBS) volumes The EBS volumes are attached to Amazon EC2 Linux Instances A SysOps administrator must set up an Amazon CloudWatch alarm that provides an alert when disk utilization increases to more than 80%. Which combination of steps must the SysOps administrator lake lo meet these requirements? (Select THREE.)
A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances on AWS. A SysOps administrator needs to keep the instances and all of the instances' data, even if someone deletes the stack. Which solution will meet these requirements?
A SysOps administrator is optimizing the cost of a workload. The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the compute. The overall usage is predictable. The amount of compute that is consumed in each Region varies, depending on the users' locations. Which approach should the SysOps administrator use to optimize this workload?

A company has an application that collects notifications from thousands of alarm systems. The notifications include alarm notifications and information notifications. The information notifications include the system arming processes, disarming processes, and sensor status. All notifications are kept as messages in an Amazon Simple Queue Service (Amazon SQS) queue. Amazon EC2 instances that are in an Auto Scaling group process the messages. A SysOps administrator needs to implement a solution that prioritizes alarm notifications over information notifications. Which solution will meet these requirements?
A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files. A SysOps administrator sets up a new S3 bucket. DOC-EXAMPLE-BUCKET, to support a new workload. The new S3 bucket also receives regular uploads of large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing S3 buckets provide. What should the SysOps administrator do to remediate this issue?
The SysOps administrator must modify the AWS Config rule that deletes noncompliant SSH inbound rules to update the rule to allow SSH from specific trusted IP addresses instead.

A SysOps administrator must implement a limited rollout of a new version of the website to 20% of customers using Amazon Route 53.

A.

Create a target group in Route 53. Set the routing algorithm to Weighted. Configure a weight of 80 for the original resource. Configure a weight of 20 for the new resource.

Answers
A.

Create a target group in Route 53. Set the routing algorithm to Weighted. Configure a weight of 80 for the original resource. Configure a weight of 20 for the new resource.

B.

Create a weighted routing policy. Configure a weight of 80 for the record that points to the original resource. Configure a weight of 20 for the record that points to the new resource.

Answers
B.

Create a weighted routing policy. Configure a weight of 80 for the record that points to the original resource. Configure a weight of 20 for the record that points to the new resource.

C.

Create a multivalue answer routing policy. Configure a weight of 80 for the record that points to the original resource. Configure a weight of 20 for the record that points to the new resource. Enable session affinity (sticky sessions).

Answers
C.

Create a multivalue answer routing policy. Configure a weight of 80 for the record that points to the original resource. Configure a weight of 20 for the record that points to the new resource. Enable session affinity (sticky sessions).

D.

Create a failover routing policy. Configure 80% of the website traffic to go to the original resource. Configure the remaining 20% of traffic as the failover record that points to the new resource.

Answers
D.

Create a failover routing policy. Configure 80% of the website traffic to go to the original resource. Configure the remaining 20% of traffic as the failover record that points to the new resource.

Suggested answer: B

Explanation:

Weighted routing in Route 53 allows you to direct a percentage of traffic to different resources by configuring specific weights. For this requirement, you can:

Weighted Routing Policy: This is the most suitable approach for gradually rolling out a new version by controlling traffic distribution.

Weight Configuration: Setting a weight of 80 for the original resource and 20 for the new resource ensures that 80% of the traffic continues to go to the existing version, while 20% is directed to the new version.

Other routing policies, such as failover and multivalue answer, are not intended for traffic distribution based on percentage; they serve different use cases.
