Answer 1

Question 4:

Correct Answer is   a. fping -g 172.217.4.36 172.217.4.40

Explanation:

fping -g command utility checks whether the provide list or range of ip addresses is reponding to the request or not.

we can use fping in two ways

fping -g <IP netmask>                       eg: fping -g 192.168.1.0/24

or

fping -g <Starting Ip> <Ending IP>      eg: fping -g 192.168.1.0 192.168.1.255

Now coming to the options,

option a is correct because there are 5 ip addresses between 172.217.4.36 and 172.217.4.40

option b in incorrect because this the syntax is not correct. i.e (not from the two ways given above)

option c is incorret because the syntax is not correct. i.e (not from the two ways given above).

option d is obviously incorrect given that b and c are incorrect.

Question 5.

correct Answer is   c. fping -g 139.67.8.128-130

Explanation:

we can use fping in two ways

fping -g <IP netmask>                       eg: fping -g 192.168.1.0/24

or

fping -g <Starting Ip> <Ending IP>      eg: fping -g 192.168.1.0 192.168.1.255

Now coming to options,

option a is correct way to use fping as we have starting and ending ip addresses, hence a valid fping command . hence incorrect option for this question.

option b is also a correct way to use fping as we have Ip netmask, hence a valid fping command. hence incorrect option for this question.

option c is not the correct way to use fping command, hence is not valid fping command, hence correct choice for this question.
