Question 104

A company's security engineer has been tasked with restricting a contractor's IAM account access to the company's Amazon EC2 console without providing access to any other IAM services The contractors IAM account must not be able to gain access to any other IAM service, even it the IAM account rs assigned additional permissions based on IAM group membership

What should the security engineer do to meet these requirements''

Options:

Create an mime IAM user policy that allows for Amazon EC2 access for the contractor's IAM user

Create an IAM permissions boundary policy that allows Amazon EC2 access Associate the contractor's IAM account with the IAM permissions boundary policy

Create an IAM group with an attached policy that allows for Amazon EC2 access Associate the contractor's IAM account with the IAM group

Create a IAM role that allows for EC2 and explicitly denies all other services Instruct the contractor to always assume this role

Question 105

A company is attempting to conduct forensic analysis on an Amazon EC2 instance, but the company is unable to connect to the instance by using AWS Systems Manager Session Manager. The company has installed AWS Systems Manager Agent (SSM Agent) on the EC2 instance.

The EC2 instance is in a subnet in a VPC that does not have an internet gateway attached. The company has associated a security group with the EC2 instance. The security group does not have inbound or outbound rules. The subnet's network ACL allows all inbound and outbound traffic.

Which combination of actions will allow the company to conduct forensic analysis on the EC2 instance without compromising forensic data? (Select THREE.)

Options:

Update the EC2 instance security group to add a rule that allows outbound traffic on port 443 for 0.0.0.0/0.

Update the EC2 instance security group to add a rule that allows inbound traffic on port 443 to the VPC's CIDR range.

Create an EC2 key pair. Associate the key pair with the EC2 instance.

Create a VPC interface endpoint for Systems Manager in the VPC where the EC2 instance is located.

Attach a security group to the VPC interface endpoint. Allow inbound traffic on port 443 to the VPC's CIDR range.

Create a VPC interface endpoint for the EC2 instance in the VPC where the EC2 instance is located.

Question 106

A company wants to remove all SSH keys permanently from a specific subset of its Amazon Linux 2 Amazon EC2 instances that are using the same 1AM instance profile However three individuals who have IAM user accounts will need to access these instances by using an SSH session to perform critical duties

How can a security engineer provide the access to meet these requirements'?

Options:

Assign an 1AM policy to the instance profile to allow the EC2 instances to be managed by AWS Systems Manager Provide the 1AM user accounts with permission to use Systems Manager Remove the SSH keys from the EC2 instances Use Systems Manager Inventory to select the EC2 instance and connect

Assign an 1AM policy to the 1AM user accounts to provide permission to use AWS Systems Manager Run Command Remove the SSH keys from the EC2 instances Use Run Command to open an SSH connection to the EC2 instance

Assign an 1AM policy to the 1AM user accounts to provide permission to use the EC2 service in the AWS Management Console Remove the SSH keys from the EC2 instances Connect to the EC2 instance as the ec2-user through the AWS Management Console's EC2 SSH client method

Question 107

Example.com is hosted on Amazon EC2 instances behind an Application Load Balancer (ALB). Third-party host intrusion detection system (HIDS) agents that capture the traffic of the EC2 instance are running on each host. The company must ensure they are using privacy enhancing technologies for users, without losing the assurance the third-party solution offers.

What is the MOST secure way to meet these requirements?

Options:

Enable TLS pass through on the ALB, and handle decryption at the server using Elliptic Curve Diffie-Hellman (ECDHE) cipher suites.

Create a listener on the ALB that uses encrypted connections with Elliptic Curve Diffie-Hellman (ECDHE) cipher suites, and pass the traffic in the clear to the server.

Create a listener on the ALB that uses encrypted connections with Elliptic Curve Diffie-Hellman (ECDHE) cipher suites, and use encrypted connections to the servers that do not enable Perfect Forward Secrecy (PFS).

Create a listener on the ALB that does not enable Perfect Forward Secrecy (PFS) cipher suites, and use encrypted connections to the servers using Elliptic Curve Diffie-Hellman (ECDHE) cipher suites.
