If a host’s CIDR IPv4 address is given as 13.2.0.64/22: How many bits make up the subnet part of the address?
~+ 22
~~
If a host’s CIDR IPv4 address is given as 13.2.0.64/22: How many bits make up the host part of the address?
~+ 10
~~
If a host’s CIDR IPv4 address is given as 13.2.0.64/22, is 13.2.3.137 a valid address on the same subnet?
~+ Yes~
No

How many usable host addresses are there on the subnet designated by 13.2.0.0/22?~
254~
256~
512

The telnet protocol may send every keystroke of a user at a terminal (i.e. one byte at a time) to the host in a separate TCP segment. What fraction of the data carried on the network is overhead?~
about 95%
~+ about 98%~
about 5%~
about 2%
~~
Why do we prefer TCP for telnet (instead of UDP) even though UDP would have significantly less overhead?
~+ Because we care that the bytes be delivered reliably and in order.
