efficiently

ratio, noise
Question 5:
Which best describes link-state algorithms?

distance, direction and reliability to any link on the internetwork.

distance-vector routing protocol?
A. All
B. All in network
C. All in
subnetwork

Question 9:
Which best describes convergence?
A. When messages
simultaneously reach a router and a collision occurs
B. When several routers
simultaneously route packets along the same path
C. When all routers in an internetwork have the same knowledge of the
structure and topology of the internetwork
D. When several messages are being sent to the same destination
Question 10:
What is one disadvantage of dynamic routing?
A.
Requires lots of active network administrator management
B. Can reveal everything known about an internetwork
C. Must be reconfigured if the
network is changed or stations are added

failures so crashes can be a recurring problem
Question 11:
Which protocol is a link-state routing
protocol?
A. EIGRP
B. OSPF
C. RIP
D. IGRP
Question 12:
Which term describes the situation where packets
never reach their destination but instead cycle repeatedly through the same
group of network nodes?
A. Split horizon
B. End to end messaging
C.
Convergence
D. Routing loop
Question 13:
What does a router use to identify the destination
network (LAN) of a packet within an internetwork?
A. MAC address
B. Port
address
C. SPX address
D. Network address
Question 14:
Which metric measures the passage of a data packet
through a router?
A. Exchange
B. Hop
C. Transmittal
D. Signaling
Question 15:
What will happen if routers have different sets of
LSAs?
A. A check sum procedure is initiated and faulty routing tables
repaired.
B. Routes become unreachable because routers disagree about a link.
C. A comparison is forced and subsequent convergence on a single
routing table occurs.
D. A broadcast message is sent with the master copy of
the routing table to all routers.
Question 16:
What is one disadvantage of static routing?
A.
Requires a name server on each network
B. Routing of data stops while
routers exchange routing tables
C. The network administrator must manually update the routing table
whenever a topology change occurs
D. Tends to
reveal everything known about an internetwork
Question 17:
Which protocol is a hybrid routing protocol?
A. EIGRP
B. OSPF
C. RIP
D. IGRP
Question 18:
Why are hold-down timers useful?
A. They help prevent a router from immediately using an alternate route
that includes the failed route
B. They force all routers in a segment to synchronize switching
operations
C. They reduce the amount of network traffic during high traffic
periods
D. They provide a mechanism for bypassing failed sections of the
network
Question 19:
What best describes the difference between a routed
protocol versus a routing protocol?
A. Routed protocols are used between
routers to maintain tables while routing protocols are used to carry user data.
B. Routed protocols use distance vector algorithms while routing protocols
use link-state algorithms.
C. Routed protocols are used to carry user data while routing protocols
maintain tables.
D. Routed protocols use dynamic
addressing while routing protocols use static addressing.
Question 20:
Which kind of route is set when the next hop is not
explicitly listed in the routing table?
A. Dynamic
B. Default
C.
Passive
D. Incremental
Question 21:
Which routing protocol maintains a complex database
of topology information and uses link-state advertisements (LSAs)?
A. RIP
B. IGRP
C. OSPF
D. EIGRP
Question 22:
How can the count to infinity problem be
prevented?
