Users of a company's internal web application recently experienced application performance issues for a brief period The application includes frontend web servers that run in an Amazon Elastic Kubernetes Service (Amazon EKS) cluster The application also includes a bacKend Amazon Aurora PostgreSQL DB cluster that includes one DB instance.
A SysOps administrator determines that the source of the performance issues was high utilization of the DB cluster. The single writer instance experienced more than 90% utilization for 11 minutes The cause of the high utilization was an automated report that is scheduled to run one time each week
What should the SysOps administrator do to ensure that users do not experience performance Issues each week when the report runs?
Increasing DB Instance Size:
Increasing the instance size provides more CPU and memory resources, which can help handle higher loads.
Steps:
Go to the AWS Management Console.
Navigate to RDS and select the DB instance.
Modify the instance to increase its size.
Apply the changes during the next maintenance window or immediately if it is a critical issue.
Monitoring Performance:
After resizing, monitor the instance during the next report run to ensure that it handles the load effectively.
A company uses AWS Cloud Formation to deploy its infrastructure. The company recently retired an application. A cloud operations engineer initiates CloudFormation stack deletion, and the stack gets stuck in DELETE FAILED status.
A SysOps administrator discovers that the stack had deployed a security group. The security group is referenced by other security groups in the environment. The SysOps administrator needs to delete the stack without affecting other applications.
Which solution will meet these requirements m the MOST operationally efficient manner?
Retain the Security Group:
When deleting a CloudFormation stack, you can specify resources to be retained instead of deleted.
Steps:
Go to the AWS Management Console.
Navigate to CloudFormation and select the stack.
Choose to delete the stack.
In the deletion options, specify that the security group should be retained.
This will delete the stack but keep the security group, ensuring no impact on other applications.
Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basis. Configure the function to restore the DB cluster to a point in time and then delete the previous DB cluster. This is the most operationally efficient solution that meets the requirements, as it will allow the company to reset the database on a daily basis without having to manually take and restore snapshots. The other solutions (creating a manual snapshot of the DB cluster, enabling the Backtrack feature, or exporting a manual snapshot of the DB cluster to Amazon S3) will require additional steps and resources to reset the database on a daily basis.
A company hosts an application on an Amazon EC2 instance in a single AWS Region. The application requires support for non-HTTP TCP traffic and HTTP traffic.
The company wants to deliver content with low latency by leveraging the AWS network. The company also wants to implement an Auto Scaling group with an
Elastic Load Balancer.
How should a SysOps administrator meet these requirements?
AWS Global Accelerator and Amazon CloudFront are separate services that use the AWS global network and its edge locations around the world. CloudFront improves performance for both cacheable content (such as images and videos) and dynamic content (such as API acceleration and dynamic site delivery). Global Accelerator improves performance for a wide range of applications over TCP or UDP by proxying packets at the edge to applications running in one or more AWS Regions. Global Accelerator is a good fit for non-HTTP use cases, such as gaming (UDP), IoT (MQTT), or Voice over IP, as well as for HTTP use cases that specifically require static IP addresses or deterministic, fast regional failover. Both services integrate with AWS Shield for DDoS protection.
A SysOps administrator needs to ensure that an Amazon RDS for PostgreSQL DB instance has available backups The DB instance has automated backups turned on with a backup retention period of 7 days. However, no automated backups for the DB instance have been created in the past month.
What could be the cause of the lack of automated backups?
STORAGE_FULL State:
When an RDS instance is in the STORAGE_FULL state, automated backups cannot be performed because there is insufficient storage available.
Steps to Resolve:
Go to the AWS Management Console.
Navigate to RDS and select the DB instance.
Check the storage metrics to confirm the STORAGE_FULL state.
Increase the allocated storage for the DB instance to provide sufficient space for automated backups.
Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basis. Configure the function to restore the DB cluster to a point in time and then delete the previous DB cluster. This is the most operationally efficient solution that meets the requirements, as it will allow the company to reset the database on a daily basis without having to manually take and restore snapshots.
