Amazon AWS Certified SysOps Administrator - Associate (SOA-C02) Sample Questions (Q97-Q102):

NEW QUESTION # 97
A company must ensure that any objects uploaded to an S3 bucket are encrypted.
Which of the following actions will meet this requirement? (Choose two.)

  • A. Implement Amazon Inspector to inspect objects uploaded to the S3 bucket to make sure that they are encrypted.
  • B. Implement S3 bucket policies to deny unencrypted objects from being uploaded to the buckets.
  • C. Implement Amazon S3 default encryption to make sure that any object being uploaded is encrypted before it is stored.
  • D. Implement AWS Shield to protect against unencrypted objects stored in S3 buckets.
  • E. Implement Object access control list (ACL) to deny unencrypted objects from being uploaded to the S3 bucket.

Answer: B,C
NEW QUESTION # 98
A company is using Amazon Elastic Container Sen/ice (Amazon ECS) to run a containerized application on Amazon EC2 instances. A SysOps administrator needs to monitor only traffic flows between the ECS tasks.
Which combination of steps should the SysOps administrator take to meet this requirement? (Select TWO.)

  • A. Specify the awsvpc network mode in the task definition.
  • B. Specify the bridge network mode in the task definition.
  • C. Configure VPC Flow Logs on the elastic network interface of each task.
  • D. Configure Amazon CloudWatch Logs on the elastic network interface of each task.
  • E. Specify the host network mode in the task definition.

Answer: D,E
NEW QUESTION # 99
A company is using an Amazon Aurora MySQL DB cluster that has point-in-time recovery, backtracking, and automatic backup enabled. A SysOps administrator needs to be able to roll back the DB cluster to a specific recovery point within the previous 72 hours. Restores must be completed in the same production DB cluster.
Which solution will meet these requirements?

  • A. Use backtracking to rewind the existing DB cluster to the desired recovery point.
  • B. Create an Aurora Replica. Promote the replica to replace the primary DB instance.
  • C. Use point-in-time recovery to restore the existing DB cluster to the desired recovery point.
  • D. Create an AWS Lambda function to restore an automatic backup to the existing DB cluster.

Answer: A Explanation:
Reference:
"The limit for a backtrack window is 72 hours.....Backtracking is only available for DB clusters that were created with the Backtrack feature enabled....Backtracking "rewinds" the DB cluster to the time you specify. Backtracking is not a replacement for backing up your DB cluster so that you can restore it to a point in time....You can backtrack a DB cluster quickly. Restoring a DB cluster to a point in time launches a new DB cluster and restores it from backup data or a DB cluster snapshot, which can take hours."

NEW QUESTION # 101
You need to update an existing AWS CloudFormation stack. If needed, a copy to the CloudFormation template is available in an Amazon SB bucket named cloudformation-bucket
1. Use the us-east-2 Region for all resources.
2. Unless specified below, use the default configuration settings.
3. update the Amazon EQ instance named Devinstance by making the following changes to the stack named 1700182:
a) Change the EC2 instance type to us-east-t2.nano.
b) Allow SSH to connect to the EC2 instance from the IP address range
192.168.100.0/30.
c) Replace the instance profile IAM role with IamRoleB.
4. Deploy the changes by updating the stack using the CFServiceR01e role.
5. Edit the stack options to prevent accidental deletion.
6. Using the output from the stack, enter the value of the Prodlnstanceld in the text box below:
Answer: ** Explanation:
Here are the steps to update an existing AWS CloudFormation stack:
Log in to the AWS Management Console and navigate to the CloudFormation service in the us-east-2 Region.
Find the existing stack named 1700182 and click on it.
Click on the "Update" button.
Choose "Replace current template" and upload the updated CloudFormation template from the Amazon S3 bucket named "cloudformation-bucket" In the "Parameter" section, update the EC2 instance type to us-east-t2.nano and add the IP address range 192.168.100.0/30 for SSH access.
Replace the instance profile IAM role with IamRoleB.
In the "Capabilities" section, check the checkbox for "IAM Resources"
Choose the role CFServiceR01e and click on "Update Stack"
Wait for the stack to be updated.
Once the update is complete, navigate to the stack and click on the "Stack options" button, and select "Prevent updates to prevent accidental deletion" To get the value of the Prodlnstanceld , navigate to the "Outputs" tab in the CloudFormation stack and find the key "Prodlnstanceld". The value corresponding to it is the value that you need to enter in the text box below.
Note:
You can use AWS CloudFormation to update an existing stack.
You can use the AWS CloudFormation service role to deploy updates.
You can refer to the AWS CloudFormation documentation for more information on how to update and manage stacks: https://aws.amazon.com/cloudformation/
