질문 # 320
A user has created a VPC with two subnets: one public and one private. The user is planning to run the patch update for the instances in the private subnet. How can the instances in the private subnet connect to the internet?

A. Allow outbound traffic in the security group for port 80 to allow internet updates
B. The private subnet can never connect to the internet
C. Use NAT with an elastic IP
D. Use the internet gateway with a private IP

정답：C

설명：
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. A user can create a subnet with VPC and launch instances inside that subnet. If the user has created two subnets (one private and one public), they would need a Network Address Translation (NAT) instance with the elastic IP address. This enables the instances in the private subnet to send requests to the internet (for example, to perform software updates).

질문 # 321
Can a Direct Connect link be connected directly to the Internet?

A. Yes, this can be done only for certain regions.
B. Yes, this can be done if you pay for it.
C. Yes
D. No

정답：D

설명：
AWS Direct Connect is a network service that provides an alternative to using the Internet to utilize AWS cloud service. Hence, a Direct Connect link cannot be connected to the Internet directly.

질문 # 322
A company is running an application in the AWS Cloud. The core business logic is running on a set of Amazon EC2 instances in an Auto Scaling group. An Application Load Balancer (ALB) distributes traffic to the EC2 instances. Amazon Route 53 record api.example.com is pointing to the ALB.
The company's development team makes major updates to the business logic. The company has a rule that when changes are deployed, only 10% of customers can receive the new logic during a testing window. A customer must use the same version of the business logic during the testing window.
How should the company deploy the updates to meet these requirements?

A. Create a second target group that is referenced by the ALB. Deploy the new logic to EC2 instances in this new target group. Update the ALB listener rule to use weighted target groups. Configure ALB target group stickiness.
B. Create a second Auto Scaling group that is referenced by the ALB. Deploy the new logic on a set of EC2 instances in this new Auto Scaling group. Change the ALB routing algorithm to least outstanding requests (LOR). Configure ALB session stickiness.
C. Create a second ALB, and deploy the new logic to a set of EC2 instances in a new Auto Scaling group.
Configure the ALB to distribute traffic to the EC2 instances. Update the Route 53 record to use weighted routing, and point the record to both of the ALBs.
D. Create a new launch configuration for the Auto Scaling group. Specify the launch configuration to use the AutoScaIingRoIIingUpdate policy, and set the MaxBatchSize option to 10. Replace the launch configuration on the Auto Scaling group. Deploy the changes.

정답：A

설명：
The company should create a second target group that is referenced by the ALB. The company should deploy the new logic to EC2 instances in this new target group. The company should update the ALB listener rule to use weighted target groups. The company should configure ALB target group stickiness. This solution will meet the requirements because weighted target groups are a feature that enables you to distribute traffic across multiple target groups using a single listener rule. You can specify a weight for each target group, which determines the percentage of requests that are routed to that target group. For example, if you specify two target groups, each with a weight of 10, each target group receives half the requests1. By creating a second target group and deploying the new logic to EC2 instances in this new target group, the company can have two versions of its business logic running in parallel. By updating the ALB listener rule to use weighted target groups, the company can control how much traffic is sent to each version. By configuring ALB target group stickiness, the company can ensure that a customer uses the same version of the business logic during the testing window. Target group stickiness is a feature that enables you to bind a user's session to a specific target within a target group for the duration of the session2.
The other options are not correct because:
Creating a second ALB and deploying the new logic to a set of EC2 instances in a new Auto Scaling group would not be as cost-effective or simple as using weighted target groups. A second ALB would incur additional charges and require more configuration and management. Updating the Route 53 record to use weighted routing would not ensure that a customer uses the same version of the business logic during the testing window, as DNS caching could affect how requests are routed.
Creating a new launch configuration for the Auto Scaling group and replacing it on the Auto Scaling group would not allow for gradual traffic shifting between versions. A launch configuration is a template that an Auto Scaling group uses to launch EC2 instances. You can specify information such as the AMI ID, instance type, key pair, security groups, and block device mapping for your instances3.
However, replacing the launch configuration on an Auto Scaling group would affect all instances in that group, not just 10% of customers.
Creating a second Auto Scaling group and changing the ALB routing algorithm to least outstanding requests (LOR) would not allow for controlled traffic shifting between versions. A second Auto Scaling group would require more configuration and management. The LOR routing algorithm is a feature that enables you to route traffic based on how quickly targets respond to requests. The load balancer selects a target from the target group with the fewest outstanding requests4. However, this algorithm does not take into account customer sessions or weights.

질문 # 323
A financial company needs to create a separate AWS account for a new digital wallet application. The company uses AWS Organizations to manage its accounts. A solutions architect uses the 1AM user Supportl from the management account to create a new member account with finance1@example.com as the email address.
What should the solutions architect do to create IAM users in the new member account?

A. Go to the AWS Management Console sign-in page. Choose "Sign in using root account credentials." Sign in in by using the email address finance1@example.com and the management account's root password. Set up the IAM users as required.
B. Sign in to the AWS Management Console with AWS account root user credentials by using the
64-character password from the initial AWS Organizations email senttofinance1@example.com. Set up the IAM users as required.
C. Go to the AWS Management Console sign-in page. Sign in by using the account ID of the new member account and the Supportl IAM credentials. Set up the IAM users as required.
D. From the management account, switch roles to assume the OrganizationAccountAccessRole role with the account ID of the new member account. Set up the IAM users as required.

정답：C

설명：
The best solution is to turn on the Concurrency Scaling feature for the Amazon Redshift cluster. This feature allows the cluster to automatically add additional capacity to handle bursts of read queries without affecting the performance of write queries. The additional capacity is transparent to the users and is billed separately based on the usage. This solution meets the business requirements of servicing read and write queries at all times and is also cost-effective compared to the other options, which involve provisioning additional resources or resizing the cluster.

질문 # 324
You deployed your company website using Elastic Beanstalk and you enabled log file rotation to S3. An
Elastic Map Reduce job is periodically analyzing the logs on S3 to build a usage dashboard that you share
with your CIO.
You recently improved overall performance of the website using Cloud Front for dynamic content delivery
and your website as the origin.
After this architectural change, the usage dashboard shows that the traffic on your website dropped by an
order of magnitude. How do you fix your usage dashboard'?

A. Use Elastic Beanstalk "Rebuild Environment" option to update log delivery to the Elastic Map Reduce
job.
B. Turn on Cloud Trail and use trail log tiles on S3 as input of the Elastic Map Reduce job
C. Use Elastic Beanstalk 'Restart App server(s)" option to update log delivery to the Elastic Map Reduce
job.
D. Change your log collection process to use Cloud Watch ELB metrics as input of the Elastic
MapReduce job
E. Enable Cloud Front to deliver access logs to S3 and use them as input of the Elastic Map Reduce job.

정답：A
