Beth would like to run an nmap scan against all of the systems on her organization's private network. these include systems in the 10.0.0.0 private address space. she would like to scan this entire private address space because she is not certain what subnets are used. what network address should beth specify as the target of her scan?
a. 10.0.0.0/0.
b. 10.0.0.0/8.
c. 10.0.0.0/16.
d. 10.0.0.0/24.

B. 10.0.0.0/8.

Explanation:

Using an 8-bit subnet mask ensures the network address is represented by the first octet of the IP address and is very efficient.

The suffix /8 implies that Beth checks all devices in the 10.0.0.0 network (hosts between 10.0.0.0 and 10.255.255.255).

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.

this seems to be in the wrong category. but i'll take some free points my dude

posting this in wrong category will result in people seeing it who won't know the answer.
