Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Install SSH server, then configure SSH server, then generate SSH key pair, then copy public key to server, then restart SSH service and test.
Install SSH server, configure it, generate keys, copy public key, restart and test.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Install SSH server, then configure SSH server, then generate SSH key pair, then copy public key to server, then restart SSH service and test.
Why this is correct
This is the correct order because you first install the SSH server software, then configure it to allow key-based authentication, generate the key pair on the client, copy the public key to the server, and finally restart the service and test the connection.
- ✗
Generate SSH key pair, then install SSH server, then configure SSH server, then copy public key, then restart and test.
Why it's wrong here
This is incorrect because you must have the SSH server installed before you can copy keys to it or test the connection. Generating keys before installing the server is possible but inefficient; the server itself needs to be installed first.
- ✗
Install SSH server, then generate SSH key pair, then copy public key, then configure SSH server, then restart and test.
Why it's wrong here
This is incorrect because configuring the SSH server (to enable key-based authentication) should be done before copying the public key and restarting. If you copy the key before configuring, the server might not accept key-based authentication, leading to failure.
- ✗
Install SSH server, then configure SSH server, then copy public key, then generate SSH key pair, then restart and test.
Why it's wrong here
This is incorrect because you must generate the SSH key pair before you can copy the public key. Copying a non-existent key is impossible. The key generation step must precede the copy step.
