101-500 Exam - Question 21


When is the content of the kernel ring buffer reset? (Choose two.)

Show Answer
Correct Answer: AE

The content of the kernel ring buffer is reset when the ring buffer is explicitly reset using the command dmesg --clear because this command is specifically designed to clear the ring buffer. Additionally, the ring buffer is reset when the system is shut down or rebooted because the buffer is stored in volatile memory, which is cleared when power is cycled.

Answers are correct! Kernel ring buffer is reset either via command or power off because it is a volatile memory!
