Correct Answer: 2.4GHz
Explanation:
The IEEE 802.11b and IEEE 802.11g standards both run in the 2.4GHz RF range.
Correct Answer: A
Explanation:
Class A addressing provides 24 bits for host addressing.
Correct Answer: 12
Explanation:
The IEEE 802.11a standard provides up to 12 non-overlapping channels.
Correct Answer: 10.0.0.0
Explanation:
The network 10.0.0.0 cannot be placed in the next router's routing table because it already is at 15 hops. One more hop would make the route 16 hops, and that is not valid in RIP networking.
Correct Answer: (config-if)# ip access-group Blocksales in
Explanation:
Using a named access list just replaces the number used when applying the list to the router's interface.
ip access-group Blocksales in is correct.
Correct Answer: FF02::9
Explanation:
RIPng uses the multicast IPv6 address of
FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same.
Correct Answer: About 175 feet
Explanation:
The IEEE 802.11a standard's lowest data rate is 6Mbps, but it can run from a distance of about 175 feet.
Correct Answer: Outside local
Explanation:
The host on the global network before translation is considered to be an outside local host.
Correct Answer: show access-lists
Explanation:
To see the contents of all access lists, use the
show access-lists command.
Correct Answer: TCP
Explanation:
Although Telnet does use TCP and IP (TCP/IP), the question specifically asks about layer 4, and IP works at layer 3. Telnet uses TCP at layer 4.
