A firewall administrator proposes opening public inbound SSH solely to make Arc communicate with Azure. What is the better design?

Choose the single best answer.

  1. A.Allow only inbound HTTPS and block the agent outbound endpoints
  2. B.Require an inbound public SSH connection from Azure service endpoints
  3. C.Provide required outbound agent connectivity and keep unnecessary inbound management closed
  4. D.Allow outbound access only during installation, then close it
Show the answer and explanation

✓ Correct answer

  • Provide required outbound agent connectivity and keep unnecessary inbound management closed

Provide the required ongoing outbound connectivity. Arc agent communication does not depend on opening public inbound SSH or HTTPS to the host. Allowing endpoints only during installation breaks subsequent agent operation and management.
