  • D. It is not possible to give permission to multiple IAM users
Answer: C

AWS Elastic Load Balancer supports SSL termination.
  • A. True. For specific availability zones only.
  • B. False

  • D. True. For all regions
Answer: D
Explanation:
You can configure your load balancer in ELB (Elastic Load Balancing) to use a SSL certificate in order to
improve your system security.The load balancer uses the certificate to terminate and then decrypt
requests before sending them to the back-end instances. Elastic Load Balancing uses AWS Identity and
Access Management (IAM) to upload your certificate to your load balancer.

NEW QUESTION # 209
A developer is creating a new batch application that will run on an Amazon EC2 instance. The application requires read access to an Amazon S3 bucket. The developer needs to follow security best practices to grant S3 read access to the application.
Which solution meets these requirements?
  • A. Add the permissions to an 1AM policy. Use 1AM web identity federation to access the S3 bucket with the policy.
  • B. Add the permissions to an 1AM policy. Attach the policy to a role. Attach the role to the EC2 instance profile.
  • C. Add the permissions inline to an 1AM group. Attach the group to the EC2 instance profile.
  • D. Add the permissions to an 1AM policy. Attach the policy to a user. Attach the user to the EC2 instance profile.
Answer: B
Explanation:
Step 1: Understanding the Requirements
* Best Practices for Security:
* Minimize the use of hardcoded credentials or long-lived access keys.
* Use IAM roles for EC2 instances to securely grant permissions to applications running on the instance.
* Access Scope: The application needs read-only access to an S3 bucket.
Step 2: Solution Analysis
* Option A:
* Define an IAM policy with the required s3:GetObject permissions.
* Attach this policy to an IAM role.
* Assign the role to the EC2 instance profile.
* This approach follows security best practices by eliminating the need for static credentials and using temporary, scoped credentials provided by the instance profile.
* Correct option.
* Option B:
* IAM groups are used for organizing users, not for EC2 instances or instance profiles.
* Not suitable.
* Option C:
* IAM users are associated with specific individuals or applications and require static credentials.
* This violates security best practices for temporary credentials and roles.
* Not suitable.
* Option D:
* IAM web identity federation is used for applications that authenticate users via third-party identity providers.
* This is unnecessary for EC2 instances and does not align with the requirements.
* Not suitable.
Step 3: Implementation Steps
* Create an IAM Policy:
* Grant read-only access to the S3 bucket:
json
Copy code
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::your-bucket-name/*"
}
]
}
* Attach the Policy to an IAM Role:
* Create an IAM role and attach the policy to the role.
* Associate the Role with the EC2 Instance:
* Attach the role to the instance profile used by the EC2 instance.
AWS Developer References:
* IAM Roles for Amazon EC2
* Amazon S3 Permissions Reference

NEW QUESTION # 210
The Developer for a retail company must integrate a fraud detection solution into the order processing solution. The fraud detection solution takes between ten and thirty minutes to verify an order. At peak, the web site can receive one hundred orders per minute.
What is the most scalable method to add the fraud detection solution to the order processing pipeline?
  • A. Add all new orders to an Amazon SQS queue. Configure a fleet of 10 EC2 instances spanning multiple AZs with the fraud detection solution installed on them to pull orders from this queue. Update the order with a pass or fails status.
  • B. Add all new orders to an SQS queue. Configure an Auto Scaling group that uses the queue depth metric as its unit of scale to launch a dynamically-sized fleet of EC2 instances spanning multiple AZs with the fraud detection solution installed on them to pull orders from this queue. Update the order with a pass or fails status.
  • C. Add all new orders to an Amazon Kinesis Stream. Subscribe a Lambda function to automatically read batches of records from the Kinesis Stream. The Lambda function includes the fraud detection software and will update the order with a pass or fail status.
  • D. Write all new orders to Amazon DynamoDB. Configure DynamoDB Streams to include all new orders.Subscribe a Lambda function to automatically read batches of records from the Kinesis Stream. The Lambda function includes the fraud detection software and will update the order with a pass or fail status.
