Amazon AWS Certified SysOps Administrator - Associate (SOA-C02) Sample Questions (Q110-Q115):
NEW QUESTION # 110
The company needs a solution to provide failover for a Single-AZ RDS for MySQL DB instance to minimize application downtime.
Options:
- A. Add a read replica in the same Availability Zone where the DB instance is deployed.
- B. Modify the DB instance to be a Multi-AZ DB instance deployment.
- C. Use RDS Proxy to configure a proxy in front of the DB instance.
- D. Add the DB instance to an Auto Scaling group that has a minimum capacity of 2 and a desired capacity of 2.
Answer: B
Explanation:
Modifying the DB instance to a Multi-AZ deployment is the recommended solution for failover and high availability in RDS. Multi-AZ RDS automatically provisions and maintains a synchronous standby replica in a different Availability Zone, allowing automatic failover in case of an instance or Availability Zone failure.
Multi-AZ Deployment: Provides resilience with automatic failover and minimizes application downtime.
No Application Changes Needed: Multi-AZ is managed by AWS, so the failover is transparent to the application.
Read replicas and Auto Scaling groups do not provide automatic failover for write operations, and RDS Proxy only improves connection management rather than high availability.
NEW QUESTION # 111
A company has several business units that want to use Amazon EC2. The company wants to require all business units to provision their EC2 instances by using only approved EC2 instance configurations.
What should a SysOps administrator do to implement this requirement?
- A. Share an AWS CloudFormation template with the business units. Instruct the business units to pass a role to AWS CloudFormation to allow the service to manage EC2 instances.
- B. Create an EC2 instance launch configuration. Allow the business units to launch EC2 instances by specifying this launch configuration in the AWS Management Console.
- C. Develop an IAM policy that limits the business units to provision EC2 instances only. Instruct the business units to launch instances by using an AWS CloudFormation template.
- D. Publish a product and launch constraint role for EC2 instances by using AWS Service Catalog. Allow the business units to perform actions in AWS Service Catalog only.
Answer: D
Explanation:
To enforce the use of approved EC2 instance configurations across different business units efficiently:
AWS Service Catalog: Utilize AWS Service Catalog to manage and govern commonly deployed IT services. Create a catalog of pre-approved products (in this case, EC2 instance configurations).
Publish Products: Define and publish EC2 instance configurations as products within the Service Catalog. These products will incorporate all the necessary and approved configurations, options, and software.
Launch Constraints: Assign launch constraints to these products, ensuring that users can only launch EC2 instances as defined by the pre-approved configurations.
Control Access: Grant business units access only to the Service Catalog for provisioning EC2 instances. This ensures they use only those configurations that comply with company policies and standards.
This approach not only standardizes resource deployment but also simplifies management and enhances compliance across the organization.
NEW QUESTION # 112
A company is undergoing an external audit of its systems, which run wholly on AWS. A SysOps administrator must supply documentation of Payment Card Industry Data Security Standard (PCI DSS) compliance for the infrastructure managed by AWS.
Which set of action should the SysOps administrator take to meet this requirement?
- A. Download complete copies of the AWS CloudTrail log files and supply these to the auditors.
- B. Provide the auditors with administrative access to the production AWS account so that the auditors can determine compliance.
- C. Download complete copies of the AWS CloudWatch logs and supply these to the auditors.
- D. Download the applicable reports from the AWS Artifact portal and supply these to the auditors.
Answer: D
NEW QUESTION # 113
A company has multiple AWS accounts. The company uses AWS Organizations with an organizational unit (OU) for the production account and another OU for the development account. Corporate policies state that developers may use only approved AWS services in the production account.
What is the MOST operationally efficient solution to control the production account?
- A. Create a customer managed policy in AWS Identity and Access Management (IAM). Apply the policy to all users within the production account.
- B. Create an IAM policy. Apply the policy in Amazon API Gateway to restrict the production account.
- C. Create a job function policy in AWS Identity and Access Management (IAM). Apply the policy to all users within the production OU.
- D. Create a service control policy (SCP). Apply the SCP to the production OU.
Answer: D
Explanation:
To control the production account efficiently, the most operationally efficient solution is to create a service control policy (SCP) and apply it to the production OU. SCPs allow you to manage permissions for AWS Organizations at the organizational unit (OU) or account level.
Service Control Policies (SCPs):
SCPs are a type of policy that can restrict what services and actions can be used in the accounts within an OU.
They are applied at the organizational unit level and provide a way to enforce corporate policies across multiple AWS accounts.
Steps to Implement:
Navigate to the AWS Organizations console.
Create a new SCP that specifies the allowed or denied services and actions.
Apply the SCP to the production OU.
Reference:
AWS Organizations SCPs
NEW QUESTION # 114
A SysOps administrator is responsible for a legacy. CPU-heavy application The application can only be scaled vertically Currently, the application is deployed on a single t2 large Amazon EC2 instance The system is showing 90% CPU usage and significant performance latency after a few minutes What change should be made to alleviate the performance problem?
- A. Upgrade to a compute-optimized instance
- B. Purchase Reserved Instances
- C. Add additional t3. large instances to the application
- D. Change the Amazon EBS volume to Provisioned lOPs
Answer: A
Explanation:
To address the performance issues of a CPU-heavy application running on a t2.large EC2 instance, the best course of action is to upgrade to a compute-optimized instance. Compute-optimized instances provide a higher ratio of CPU resources compared to memory, making them ideal for applications that require high CPU performance.
Upgrade to a Compute-Optimized Instance:
Identify a suitable compute-optimized instance type, such as the c5.large, which offers better CPU performance compared to the t2.large.
Stop the current EC2 instance and change the instance type to the chosen compute-optimized instance.
Reference:
Considerations:
Ensure that the new instance type is compatible with the existing AMI and EBS volume configuration.
Monitor the application performance after the upgrade to ensure that the new instance type meets the application's requirements.
This approach directly addresses the high CPU utilization and performance latency issues.
