CompTIA Linux+ (XK0-005) — Question 7

A systems administrator needs to clone the partition /dev/sdc1 to /dev/sdd1. Which of the following commands will accomplish this task?

Answer options

• A. tar -cvzf /dev/sdd1 /dev/sdc1
• B. rsync /dev/sdc1 /dev/sdd1
• C. dd if=/dev/sdc1 of=/dev/sdd1
• D. scp /dev/sdc1 /dev/sdd1

Correct answer: C

Explanation

The correct command is 'dd if=/dev/sdc1 of=/dev/sdd1', as 'dd' is specifically designed for low-level copying of raw data from one device to another. The other options do not perform a direct block-level copy: 'tar' and 'rsync' are used for file-level operations, while 'scp' is meant for secure file transfers over a network.
