A network automation engineer is reviewing a unified diff that shows changes to a router configuration file. The diff header reads: `--- router-config.cfg 2024-05-01 10:00:00` and `+++ router-config.cfg 2024-05-01 11:30:00`. The engineer needs to determine which file version is the 'before' state. What does the `---` line represent?

The original file before changes

A network engineer is reviewing a unified diff for a configuration file. The diff header shows `--- config.cfg 2024-05-01 10:00:00` and `+++ config.cfg 2024-05-01 11:30:00`. What can the engineer conclude from the timestamps?

The timestamps indicate when the diff was generated, not when the files were modified.

The new file was last modified at 10:00, and the original at 11:30.

The original file was last modified at 10:00, and the new file at 11:30.

The timestamps are irrelevant and can be ignored.

A network engineer is reviewing a unified diff for a configuration file. The diff header shows: --- config_old.txt 2024-07-01 10:00:00 +++ config_new.txt 2024-07-02 14:30:00 The engineer wants to know if the file was renamed. What should they look for?

A change in the file extension.

A hunk header with a different start line in the new file.

A large number of added and removed lines.

A line in the header indicating a rename, such as 'rename from' and 'rename to'.

A network automation engineer is applying a unified diff to a configuration file. The diff contains the hunk `@@ -8,3 +8,2 @@` with the following lines: `-hostname R1`, `-interface GigabitEthernet0/0`, `+hostname R2`, ` description WAN`. What will the new file contain in the affected region?

interface GigabitEthernet0/0, hostname R2, description WAN

hostname R1, hostname R2, description WAN

hostname R2, interface GigabitEthernet0/0, description WAN
