C. Adding a router to the network decreases latency.
D. Filtering can occur based on Layer 3 information.
E. Routers are more efficient than switches.

CCNA Questions

Which PPP authentication methods will you use when configuring PPP on an interface of a Cisco router?
(Select two options.)

A. SSL
B. SLIP
C. PAP
D. LAPBc
E. CHAP
F. VNP


Answer :
Answer: C E
Explanation:
Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP)
authenticate the endpoints on either end of a point-to-point serial link. Chap is the preferred method today
because the identifying codes flowing over the link are created using a MD5 one-way hash, which is more
secure that the clear-text passwords sent by PAP.

Which of the following routes will be used to forward data in a situation where a routing table contains
static, RIP, and IGRP routes destined to the same network with each set to its default administrative
distance?

A. The RIP route
B. The static route
C. The IGRP route
D. All three will load balance.


Answer :
Answer: B
Explanation:
To decide which route to use, IOS uses a concept called Administrative Distance. Administrative distance is a
number that denotes how believable an entire routing protocol is on a single router. The lower the number, the
better, or more believable the routing protocol.
Route Type Administrative Distance
• Static 1
• IGRP 100
• RIP 120

Which of the following factors determines the OSPF router ID when configuring a router with both
physical and logical interfaces?

A. The lowest network number of any interface.
B. The highest network number of any interface.
C. The highest IP address of any logical interface.
D. The middle IP address of any logical interface.
E. The lowest IP address of any physical interface.
F. The highest IP address of any physical interface.
G. The lowest IP address of any logical interface.

Answer :
Answer: F
Explanation:
The OSPF topology database includes information about routers and the subnets, or links, to which they are
attached. To identify the routers in the neighbor table’s topology database, OSPF uses a router ID (RID) for
each router. A router’s OSPF RID is that router’s highest IP address on a physical interface when OSPF starts
running.

Note: The OSPF router ID is a 32-bit IP address selected at the beginning of the OSPF process. The highest IP
address configured on the router is the router ID. If a loopback address is configured, then it is the router ID. In
case of multiple loopback addresses, the highest loopback address is the router ID. Once the router ID is elected
it doesn't change unless the IP address is removed or OSPF restarts.

A. Coaxial cable

B. Straight-through cable


C. Cross-over cable


D. Thin coax

Answer :
B. When connecting a switch to a PC, you must use a straight-through UTP cable. Answer A is incorrect because coaxial cable is typically used for cable television. Answer C is incorrect because cross-over cables are used to connect like devices such as switches to other switches or PCs to other PCs. Answer D is incorrect because thin coax (also known as thinnet) is used in older network topologies.
