How does proper disk management help prevent system outages?

Proper disk management prevents outages by avoiding disk full errors, reducing fragmentation, and ensuring backups and monitoring are in place to catch issues early.

Why is monitoring disk space important for preventing outages?

Monitoring disk space helps detect when storage is running low, allowing action before the system crashes or services stop working.

What role do backups play in disk management to avoid outages?

Backups ensure data can be restored quickly after disk failures, minimizing downtime and preventing data loss.

Which Linux command shows disk usage and helps prevent outages by monitoring space?

A ping

B ls

C cat

D df

The 'df' command displays disk space usage, helping admins monitor free space to avoid outages.

What happens if a disk becomes completely full on a Linux system?

A System may crash or services stop working

B Nothing, system runs normally

C Disk automatically expands

D Files get deleted automatically

A full disk can cause system crashes or service failures because no space is left for operations.

Which tool is used to create or modify disk partitions in Linux?

A fdisk

B top

C grep

D chmod

'fdisk' is a command-line tool to create and manage disk partitions.

Why is regular backup important in disk management?

A To speed up the disk

B To restore data after disk failure

C To increase disk size

D To delete old files automatically

Backups allow recovery of data if the disk fails, preventing data loss and outages.

What is fragmentation and why should it be managed?

A Disk overheating

B Virus infection

C Files scattered on disk slowing access

D Disk encryption

Fragmentation means files are split across the disk, slowing read/write speeds and potentially causing issues.
