Question No. 1

A SysOps administrator is configuring an application on Amazon EC2 instances for a company Teams in other countries will use the application over the internet. The company requires the application endpoint to have a static pubic IP address.

How should the SysOps administrator deploy the application to meet this requirement?

ABehind an Amazon API Gateway API

BBehind an Application Load Balancer

CBehind an internet-facing Network Load Balancer

DIn an Amazon CloudFront distribution

Show Answer

Correct Answer: C

To ensure that the application endpoint has a static public IP address, the SysOps administrator should deploy the application behind an internet-facing Network Load Balancer (NLB):

Network Load Balancer:

An NLB automatically provides a static IP address that can be associated with the load balancer. It supports static IP addresses for each Availability Zone and can handle a high number of requests per second.

Configuration Steps:

Create an internet-facing NLB and configure the target groups to point to the EC2 instances running the application.

Assign Elastic IP addresses to the NLB for a static public IP.

Question No. 2

A SysOps administrator creates two VPCs, VPC1 and VPC2, in a company's AWS account The SysOps administrator deploys a Linux Amazon EC2 instance in VPC1 and deploys an Amazon RDS for MySQL DB instance in VPC2. The DB instance is deployed in a private subnet. An application that runs on the EC2 instance needs to connect to the database.

What should the SysOps administrator do to give the EC2 instance the ability to connect to the database?

AEnter the DB instance connection string into the VPC1 route table.

BConfigure VPC peering between the two VPCs.

CAdd the same IPv4 CIDR range for both VPCs.

DConnect to the DB instance by using the DB instance's public IP address.

Show Answer

Correct Answer: B

VPC peering allows two VPCs to communicate with each other securely. By configuring VPC peering between the two VPCs, the SysOps administrator will be able to give the EC2 instance in VPC1 the ability to connect to the database in VPC2. Once the VPC peering is configured, the EC2 instance will be able to communicate with the database using the private IP address of the DB instance in the private subnet.

Question No. 3

A SysOps administrator creates an AWS CloudFormation template to define an application stack that can be deployed in multiple AWS Regions.

The SysOps administrator also creates an Amazon CloudWatch dashboard by using the AWS Management Console. Each deployment of the application requires its own CloudWatch dashboard.

How can the SysOps administrator automate the creation of the CloudWatch dashboard each time the application is deployed?

ACreate a script by using the AWS CLI to run the aws cloudformation put-dashboard command with the name of the dashboard. Run the command each time a new CloudFormation stack is created.

BExport the existing CloudWatch dashboard as JSON. Update the CloudFormation template to define an AWS::CloudWatch::Dashboard resource. Include the exported JSON in the resource's DashboardBody property.

CUpdate the CloudFormation template to define an resource. Use the intrinsic Ref function to reference the ID of the existing CloudWatch dashboard.
D. Update the CloudFormation template to define an AWS::CloudWatch::Dashboard resource. Specify the name of the existing
dashboard in the DashboardName property.

Show Answer

Correct Answer: B

You can only use the Intrinsic Ref function to reference a resource that is being created at the same time as the current CloudFormation template. The question states that the CloudWatch dashboard was previously created using the AWS Management Console, so there is no ID to reference the existing CloudWatch dashboard in the CloudFormation template. You would need to export the existing CloudWatch dashboard as JSON, then use the DashboardBody property in the CloudFormation template to replicate it upon each deployment (https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/CloudWatch-Dashboard-Body-Structure.html)

Question No. 4

A company uses AWS Organizations to host several applications across multiple AWS accounts. Several teams are responsible for building and maintaining the infrastructure of the applications across the AWS accounts.

A SysOps administrator must implement a solution to ensure that user accounts and permissions are centrally managed. The solution must be integrated with the company's existing on-premises Active Directory environment. The SysOps administrator already has enabled AWS 1AM Identity Center (AWS Single Sign-On) and has set up an AWS Direct Connect connection.

What is the MOST operationally efficient solution that meets these requirements?

ACreate a Simple AD domain, and establish a forest trust relationship with the on-premises Active Directory domain. Set the Simple AD domain as the identity source for 1AM Identity Center. Create the required role-based permission sets. Assign each group of users to the AWS accounts that the group will manage.

BCreate an Active Directory domain controller on an Amazon EC2 instance that is joined to the on-premises Active Directory domain. Set the Active Directory domain controller as the identity source for 1AM Identity Center. Create the required role-based permission sets. Assign each group of users to the AWS accounts that the group will manage.

CCreate an AD Connector that is associated with the on-premises Active Directory domain. Set the AD Connector as the identity source for 1AM Identity Center. Create the required role-based permission sets. Assign each group of users to the AWS accounts that the group will manage.

DUse the built-in SSO directory as the identity source for 1AM Identity Center. Copy the users and groups from the on-premises Active Directory domain. Create the required role-based permission sets. Assign each group of users to the AWS accounts that the group will manage.

Show Answer

Correct Answer: C

To manage user accounts and permissions across multiple AWS accounts and integrate with an on-premises Active Directory, using AD Connector is the most operationally efficient solution. AD Connector serves as a directory gateway with which you can redirect directory requests to your on-premises Microsoft Active Directory without storing any directory data in the cloud. This setup allows IAM Identity Center to use the existing corporate credentials, ensuring centralized management and seamless user access control. Option C perfectly meets these requirements by leveraging existing infrastructure with minimal changes. AWS documentation on AD Connector offers guidance AWS Directory Service AD Connector.

Question No. 5

A company has created a NAT gateway in a public subnet in a VPC. The VPC also contains a private subnet that includes Amazon EC2 instances. The EC2 instances use the NAT gateway to access the internet to download patches and updates. The company has configured a VPC flow log for the elastic network interface of the NAT gateway. The company is publishing the output to Amazon CloudWatch Logs.

A SysOps administrator must identify the top five internet destinations that the EC2 instances in the private subnet communicate with for downloads.

What should the SysOps administrator do to meet this requirement in the MOST operationally efficient way?

AUse AWS CloudTrail Insights events to identify the top five internet destinations.

BUse Amazon CloudFront standard logs (access logs) to identify the top five internet destinations.

CUse CloudWatch Logs Insights to identify the top five internet destinations.

DChange the flow log to publish logs to Amazon S3. Use Amazon Athena to query the log files in Amazon S3.

Show Answer

Correct Answer: C

Amazon CloudWatch Logs Insights allows you to interactively search and analyze your log data. This can be used to quickly identify the top internet destinations accessed by the EC2 instances.

Steps:

Open CloudWatch Logs Insights:

Open the Amazon CloudWatch console.

In the navigation pane, choose 'Logs Insights'.

Select the Log Group:

Select the log group that contains the VPC flow logs for the NAT gateway.

Run a Query:

Use the following query to identify the top five internet destinations:

sql

Copy code

fields @timestamp, dstAddr

| stats count(*) as requestCount by dstAddr

| sort requestCount desc

| limit 5

This query will count the number of requests to each destination address, sort them in descending order, and limit the results to the top five.

Analyze Results:

Review the output to identify the top five internet destinations that the EC2 instances communicate with for downloads.
