17
Q

pinging the loopback address 127.0.0.1 verifies the NIC is functioning, true or false?

A

False. It only verifies the TCP/IP software stack is working.

18
Q

connection state
active connections
routing table interface statics

are all the main categories of information that netstat can display, true or false?

A

False - connection state (only according the the test questions! The justification was that “the connection state of the computer”, which isn’t what the question asked. Netstat DOES display a column called STATE.

19
Q

Which tester can detect split pairs?

A

Cable certifier

20
Q

If there is a mixture of T568A and T568B wiring between the switch and the wall-plate, and you connect a patch cable from the patch panel to the switch, it won’t matter if you don’t reconcile the mixture of wiring leading back to the wall-plate because the switch will automatically flip the pins electronically the right way around. - true or false?

A

True

21

A

True. e.g. a windows system will send an arp request out when it joins a network to first check another computer isn’t using the same ip.

27
Q

If after running the command to view the routing table you do not see an address of 0.0.0.0 what does that mean?

A

There is no default gateway configured.

28
Q

Do routing tables specify the address of the DNS server?

A

No

29
