A company wants to use thin clients running virtual desktops to replace 500 desktop computers used by its call center employees. The company is evaluating Amazon WorkSpaces as a solution.

A network engineer who is testing with a thin client is unable to connect to Amazon WorkSpaces. After entering credentials, the network engineer receives the following error:

“An error occurred while launching your WorkSpace. Please try again.”

What should the network engineer do to resolve this issue?

• Update the inbound rules on the network ACL on the subnets used for Amazon WorkSpaces to allow UDP on port 4172 and TCP on port 4172.
• Update the company’s corporate firewall to allow outbound access to UDP on port 4172 and TCP on port 4172. Open inbound ephemeral ports explicitly to allow return communication.
• Update the inbound rules on the security group assigned to Amazon WorkSpaces to allow UDP on port 4172 and TCP on port 4172.
• Update the company’s corporate firewall to allow inbound access to UDP on port 4172 and TCP on port 4172. Open outbound ephemeral ports explicitly to allow return communication.
