- Question
Which of the following are true regarding OSPF areas?
- You must have separate loopback interfaces configured in each area.
- The numbers you can assign an area go up to 65,535.
- The backbone area is also called area 0.
- If your design is hierarchical, then you don't need multiple areas.
- All areas must connect to area 0.
Options- A. 1 only
- B. 1 and 2 only
- C. 3 and 4 only
- D. 3, 4 and 5
- Correct Answer
- 3, 4 and 5
ExplanationLoopback interfaces are created on a router, and the highest IP address on a loopback (logical) interface becomes the RID of the router but has nothing to do with areas and is optional, so (1) is wrong. The numbers you can create an area with are from 0 to 4,294,967,295 option (2) is wrong. The backbone area is called area 0, so option (3) is correct. All areas must connect to area 0, so option (5) is correct. If you have only one area, it must be called area 0. This leaves option (4), which must be correct; it doesn't make much sense, but it is the best answer. - 1. You have created a named access list called Blocksales.

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.
Correct Answer: NCP
Explanation:
Network Control Protocol is used to help identify the Network layer protocol used in the packet.
Correct Answer: access-list 110 permit tcp any host 1.1.1.1 eq smtp
Explanation:
When trying to find the best answer to an access-list question, always check the access-list number and then the protocol. When filtering to an upper-layer protocol, you must use an extended list, numbers 100-199 and 2000-2699. Also, when you filter to an upper-layer protocol, you must use either
tcp or
udp in the protocol field. If it says
ip in the protocol field, you cannot filter to an upper-layer protocol. SMTP uses TCP.
Correct Answer: The packet will be discarded.
Explanation:
Since the routing table shows no route to the 192.168.22.0 network, the router will discard the packet and send an ICMP destination unreachable message out interface FastEthernet 0/0, which is the source LAN where the packet originated from.
Correct Answer: 3 and 4
Explanation:
IPv4 addresses are 32 bits long and are represented in decimal format. IPv6 addresses are 128 bits long and represented in hexadecimal format.
