SOA-C02 Sample Question 2


A company has developed a service that is deployed on a fleet of Linux-based Amazon
EC2 instances that are in an Auto Scaling group. The service occasionally fails
unexpectedly because of an error in the application code. The company's engineering team

Amazon EC2 Auto Scaling group that uses a launch template The amount of application
traffic changes throughout the day. Scaling events happen frequently.
A SysOps administrator needs to help developers troubleshoot the application. When a
scaling event removes an instance. EC2 Auto Scaling terminates the instance before the
developers can log in to the instance to diagnose issues.
Which solution will prevent termination of the instance so that the developers can log in to
the instance?

SOA-C02 Sample Question 31


A SysOps administrator is investigating a company's web application for performance
problems The application runs on Amazon EC2 instances that are in an Auto Scaling
group. The application receives large traffic increases at random times throughout the day.
During periods of rapid traffic increases, the Auto Scaling group is not adding capacity fast
enough. As a result, users are experiencing poor performance.
The company wants to minimize costs without adversely affecting the user experience
when web traffic surges quickly. The company needs a solution that adds more capacity to
me Auto Scaling group for larger traffic increases than for smaller traffic increases.
How should the SysOps administrator configure the Auto Scaling group to meet these
requirements?

A. Create a simple scaling policy with settings to make larger adjustments in capacity whenthe system is under heavy load
B. Create a step scaling policy with settings to make larger adjustments in capacity whenthe system is under heavy load.
C. Create a target tracking scaling policy with settings to make larger adjustments incapacity when the system is under heavy load
D. Use Amazon EC2 Auto Scaling lifecycle hooks Adjust the Auto Scaling group'smaximum number of instances after every scaling event

SOA-C02 Sample Question 32


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?

A. Create a Simple AD domain, and establish a forest trust relationship with the onpremisesActive Directory domain. Set the Simple AD domain as the identity source for1AM Identity Center. Create the required role-based permission sets. Assign each group ofusers to the AWS accounts that the group will manage.
B. Create an Active Directory domain controller on an Amazon EC2 instance that is joinedto the on-premises Active Directory domain. Set the Active Directory domain controller asthe 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.
C. Create an AD Connector that is associated with the on-premises Active Directorydomain. Set the AD Connector as the identity source for 1AM Identity Center. Create therequired role-based permission sets. Assign each group of users to the AWS accounts thatthe group will manage.
D. Use the built-in SSO directory as the identity source for 1AM Identity Center. Copy theusers and groups from the on-premises Active Directory domain. Create the required rolebasedpermission sets. Assign each group of users to the AWS accounts that the group willmanage.


ANSWER : C



SOA-C02 Sample Question 33


A SysOps administrator needs to configure an Amazon S3 bucket to host a web
application. The SysOps administrator has created the S3 bucket and has copied the static
files for the web application to the S3 bucket.
The company has a policy that all S3 buckets must not be public. What should the SysOps administrator do to meet these requirements?

A. Create an Amazon CloudFront distribution. Configure the S3 bucket as an origin with anorigin access identity (OAI). Give the OAI the s3:GetObject permission in the S3 bucketpolicy.
B. Configure static website hosting in the S3 bucket. Use Amazon Route 53 to create aDNS CNAME to point to the S3 website endpomt.
C. Create an Application Load Balancer (ALB). Change the protocol to HTTPS in the ALBlistener configuration. Forward the traffic to the S3 bucket.
D. Create an accelerator in AWS Global Accelerator. Set up a listener configuration for port443. Set the endpoint type to forward the traffic to the S3 bucket.
