Why use scripts to automate network connectivity tasks?

Which of the following is the main reason network scripts are used to automate connectivity tasks?

A To prevent any changes to network settings

B To make the network slower and less reliable

C To increase the number of manual steps needed

D To reduce manual errors and save time by repeating tasks automatically

💡 Hint

Think about what happens when you do the same task many times by hand.

Network scripts help by doing repetitive tasks quickly and without mistakes, saving time and effort.

💻 Command Output

What does this script automate in network management?

Given this bash script snippet, what network task is it automating? for ip in 192.168.1.{1..5}; do ping -c 1 $ip > /dev/null && echo "$ip is reachable" || echo "$ip is unreachable" done

A Checking which IP addresses in a range respond to ping

B Blocking unreachable IP addresses automatically

C Restarting network services on each IP

D Changing IP addresses on the network

Why is automation critical for large network connectivity tasks?

Why is automating network connectivity tasks especially important in large networks?

A Because manual tasks become too slow and error-prone at scale

B Because automation makes networks less secure

C Because large networks do not need monitoring

D Because automation removes all human control permanently

💡 Hint

Think about the challenges of managing many devices manually.
