[Cost and Performance Optimization]
A company has an ecommerce application. The application runs on Amazon EC2 instances that are in an Auto Scaling group. The company runs a backend PostgreSQL database on Amazon RDS. As the number of EC2 instances increases during times of high application usage, the database's CPU utilization increases. At the same time, the database's available memory significantly decreases. A SysOps administrator must reduce the overhead of the new database connections from the Auto Scaling group in a highly available manner.
Which solution will meet this requirement?
Amazon RDS Proxy is a fully managed, highly available database proxy for Amazon RDS that helps improve the scalability, availability, and security of database applications. It allows applications to pool and share database connections, reducing the overhead associated with opening and closing connections, which can be particularly beneficial in scenarios with fluctuating workloads, such as those managed by Auto Scaling groups.
By implementing RDS Proxy, you can:
Reduce CPU and Memory Overhead:
By managing a pool of connections, RDS Proxy reduces the number of active connections to the database, thereby decreasing the CPU and memory usage on the RDS instance.
Improve Application Scalability:
RDS Proxy can handle a large number of simultaneous connections, making it easier to scale applications without overloading the database.
Enhance Availability:
In the event of a database failover, RDS Proxy can automatically connect to a standby database instance, preserving application connections and reducing failover times.
Therefore, creating an RDS Proxy and configuring it to connect to the existing PostgreSQL database is the most effective solution to meet the company's requirements.
[Monitoring, Reporting, and Automation]
A company migrated an I/O intensive application to an Amazon EC2 general purpose instance. The EC2 instance has a single General Purpose SSD Amazon Elastic Block Store (Amazon EBS) volume attached.
Application users report that certain actions that require intensive reading and writing to the disk are taking much longer than normal or are failing completely. After reviewing the performance metrics of the EBS volume, a SysOps administrator notices that the VolumeQueueLength metric is consistently high during the same times in which the users are reporting issues. The SysOps administrator needs to resolve this problem to restore full performance to the application.
Which action will meet these requirements?
Step-by-Step
Understand the Problem:
An I/O intensive application on an Amazon EC2 general purpose instance is experiencing performance issues.
Users report delays or failures during intensive read/write operations.
The VolumeQueueLength metric is consistently high during these periods.
Analyze the Requirements:
Address the high VolumeQueueLength, which indicates that the EBS volume is unable to handle the I/O requests efficiently.
Improve the disk I/O performance to restore full application performance.
Evaluate the Options:
Option A: Modify the instance type to be storage optimized.
Storage optimized instances are designed for workloads that require high, sequential read and write access to large data sets on local storage.
This could help, but if the issue is primarily with EBS volume performance, increasing IOPS would be a more direct solution.
Option B: Modify the volume properties by deselecting Auto-Enable Volume I/O.
Auto-Enable Volume I/O is a setting that automatically enables I/O for the EBS volume after an event such as a snapshot restore.
Deselecting this option will not address the issue of high I/O demand.
Option C: Modify the volume properties to increase the IOPS.
Increasing the IOPS (Input/Output Operations Per Second) will directly address the high VolumeQueueLength by allowing the volume to handle more I/O operations concurrently.
This is the most effective and direct solution to improve the performance of I/O intensive tasks.
Option D: Modify the instance to enable enhanced networking.
Enhanced networking provides higher bandwidth, higher packet per second (PPS) performance, and consistently lower inter-instance latencies.
While beneficial for network performance, this does not directly impact the EBS volume's I/O performance.
Select the Best Solution:
Option C: Modifying the volume properties to increase the IOPS directly addresses the high VolumeQueueLength and improves the EBS volume's ability to handle intensive read/write operations.

Optimizing EBS Performance
Increasing the IOPS of the EBS volume ensures that the application can handle the required intensive read/write operations more efficiently, directly addressing the high VolumeQueueLength and restoring full performance.
[Monitoring, Reporting, and Automation]
A SysOps administrator must create a solution that immediately notifies software developers if an AWS Lambda function experiences an error.
Which solution will meet this requirement?
To immediately notify software developers if an AWS Lambda function experiences an error, follow these steps:
Create an SNS Topic:
Navigate to the Amazon SNS console and create a new topic.
Add email subscriptions for each developer to the SNS topic.
Create a CloudWatch Alarm:
Go to the Amazon CloudWatch console and create an alarm based on the Errors metric for the specific Lambda function.
Use the Lambda function name as a dimension.
Configure the alarm to trigger when the metric exceeds a threshold indicating an error.
Configure Notification:
Set the CloudWatch alarm action to send a notification to the SNS topic created in step 1 when the alarm state reaches ALARM.
This configuration ensures that developers are notified immediately via email if the Lambda function experiences an error.
[High Availability, Backup, and Recovery]
A SysOps administrator configuring AWS Client VPN to connect use's on a corporate network to AWS resources mat are running in a VPC According to compliance requirements, only traffic that is destined for the VPC can travel across the VPN tunnel.
How should the SysOps administrator configure Client VPN to meet these requirements?
Split-tunnel routing allows you to specify that only the traffic destined for your VPC is routed through the VPN tunnel. All other internet traffic is routed through the user's local network.
Steps:
Open the Client VPN Console:
Sign in to the AWS Management Console.
Open the Amazon VPC console.
Modify the Client VPN Endpoint:
Select the Client VPN endpoint.
Choose 'Modify Client VPN endpoint'.
Enable the 'Split-tunnel' option.
Update Route Table:
Ensure that the route table associated with the Client VPN endpoint routes traffic destined for the VPC IP range to the appropriate target (e.g., VPC subnet).
This configuration ensures that only traffic destined for resources in the VPC is sent over the VPN tunnel, while other traffic uses the user's local internet connection.

A company runs hundreds of Amazon EC2 instances in a single AWS Region. Each EC2 instance has two attached 1 GiB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volumes. A critical workload is using all the available IOPS capacity on the EBS volumes.
According to company policy, the company cannot change instance types or EBS volume types without completing lengthy acceptance tests to validate that the company's applications will function properly. A SysOps administrator needs to increase the I/O performance of the EBS volumes as quickly as possible.
Which action should the SysOps administrator take to meet these requirements?
Increasing the size of the 1 GiB EBS volumes will increase the IOPS capacity of the volumes, which will improve the I/O performance of the EBS volumes. This option does not require any changes to the instance types or EBS volume types, so it can be done quickly without the need for lengthy acceptance tests to validate that the company's applications will function properly.
