A company hosts an internal application on Amazon EC2 On-Demand Instances behind an Application Load Balancer (ALB). The instances are in an Amazon EC2 Auto Scaling group. Employees use the application to provide product prices to potential customers. The Auto Scaling group is configured with a dynamic scaling policy and tracks average CPU utilization of the instances.
Employees have noticed that sometimes the application becomes slow or unresponsive. A SysOps administrator finds that some instances are experiencing a high CPU load. The Auto Scaling group cannot scale out because the company is reaching the EC2 instance service quota.
The SysOps administrator needs to implement a solution that provides a notification when the company reaches 70% or more of thte EC2 instance service quota.
Which solution will meet these requirements in the MOST operationally efficient manner?
To monitor and receive alerts when the EC2 instance service quota usage reaches 70% or more:
Service Quotas Console: Navigate to the Service Quotas console within AWS and identify the specific quota for EC2 instances.
Create a CloudWatch Alarm: Directly from the Service Quotas console, set up a CloudWatch alarm for the EC2 instance quota metric. Configure the alarm to trigger when the quota utilization reaches or exceeds 70%.
Notification Setup: Link this alarm to an Amazon SNS topic that will send a notification to relevant stakeholders or systems when the quota usage threshold is breached.
This method provides an automated, straightforward way to monitor resource limits and ensures that stakeholders are promptly notified, enabling them to take proactive measures to manage the quota and prevent service disruption.
A company needs to archive all audit logs for 10 years. The company must protect the logs from any future edits.
Which solution will meet these requirements?
To meet the requirements of the workload, a company should store the data in an Amazon S3 Glacier vault and configure a vault lock policy for write-once, read-many (WORM) access. This will ensure that the data is stored securely and cannot be edited in the future. The other solutions (storing the data in an Amazon Elastic Block Store (Amazon EBS) volume and configuring AWS Key Management Service (AWS KMS) encryption, storing the data in Amazon S3 Standard-Infrequent Access (S3 Standard-IA) and configuring server-side encryption, or storing the data in Amazon S3 Standard-Infrequent Access (S3 Standard-IA) and configuring multi-factor authentication (MFA)) will not meet the requirements, as they do not provide a way to protect the audit logs from future edits.

A company's SysOps administrator deploys a public Network Load Balancer (NLB) in front of the company's web application. The web application does not use any Elastic IP addresses. Users must access the web application by using the company's domain name. The SysOps administrator needs to configure Amazon Route 53 to route traffic to the NLB.
Which solution will meet these requirements MOST cost-effectively?
To route traffic to the Network Load Balancer (NLB) using Amazon Route 53 cost-effectively, creating an alias record is the best solution.
Alias Record:
Alias records are a Route 53-specific extension to DNS functionality.
They provide a way to map a domain name to an AWS resource, such as an NLB, without incurring additional charges.
Steps to Implement:
Open the Route 53 console.
Select the hosted zone and choose 'Create Record Set.'
Choose 'Alias' and select the NLB from the drop-down list.
A company has an application that uses a scheduled AWS Lambda function to retrieve datasets from external sources over the internet. The function is not associated with a VPC. The company is modifying the application to store the information that the Lambda function retrieves on an Amazon RDS DB instance in a private subnet. The VPC has two public subnets and two private subnets.
A SysOps administrator must deploy a solution that allows the Lambda function to access the new database and continue to access the internet.
Which solution meets these requirements?
To allow the Lambda function to access both the new RDS database in a private subnet and the internet, the Lambda function needs to be reconfigured for VPC access with a NAT gateway setup.
Reconfigure Lambda for VPC Access:
Attach the Lambda function to the private subnets where the RDS instance is located.
Add NAT gateways to the public subnets to allow outbound internet access from the private subnets.
NAT Gateway:
NAT gateways allow instances in private subnets to connect to the internet or other AWS services, but they prevent the internet from initiating connections with those instances.
Steps to Implement:
Create NAT gateways in the public subnets.
Update the route tables of the private subnets to route internet-bound traffic through the NAT gateways.
Ensure the Lambda function has the necessary IAM role permissions to access the VPC and RDS.
A SysOps administrator is responsible for more than 50 Amazon EC2 instances mat are deployed in a single production AWS account The EC2 instances are running several different operating systems The company's standards require patching to be completed at least once a month.
The SysOps administrator wants to use AWS Systems Manager to reduce the number of hours the company spends on operating system patching each month.
Which combination of steps should the SysOps administrator take to meet these requirements? (Select THREE.)
Group EC2 Instances Using Resource Groups:
Resource groups help organize and manage AWS resources based on tags and other criteria.
Steps:
Go to the AWS Management Console.
Navigate to AWS Resource Groups.
Create resource groups for similar EC2 instances based on tags or other criteria.
Create a Schedule in Patch Manager:
AWS Systems Manager Patch Manager automates the process of patching managed instances.
Steps:
Go to the AWS Management Console.
Navigate to Systems Manager and select Patch Manager.
Create a patch baseline if not already created.
Create a schedule for patching and specify the resource group as the target.
Create Maintenance Windows for Resource Groups:
Maintenance windows define a period of time for performing administrative tasks on instances.
Steps:
Go to the AWS Management Console.
Navigate to Systems Manager and select Maintenance Windows.
Create a maintenance window for each resource group.
Specify tasks and targets (resource groups) for each maintenance window.
