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 8:
What is one advantage of dynamic
routing?
A. Takes
little network overhead and reduces network overhead traffic
B. Reduces
unauthorized break-ins as security is tight
C. Adjusts automatically to topology or
traffic changes
D. Requires
very little bandwidth to operate efficiently
Question 9:
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 10:
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 11:
Which routers exchange information
when using a distance-vector routing protocol?
A. All
B. All in
network
C. All in
subnetwork
D. Only
neighbors
Question 12:
What is a network with only one path
to a router called?
A. Static
network
B. Dynamic
network
C. Entity network
D. Stub
network
Question 13:
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 14:
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 15:
Which protocol is a hybrid routing
protocol?
A. EIGRP
B. OSPF
C. RIP
D. IGRP
Question 16:
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
D. Cannot
compensate for network failures so crashes can be a recurring problem
Question 17:
Which protocol is a link-state
routing protocol?
A. EIGRP
B. OSPF
C. RIP
D. IGRP
Question 18:
Which metrics are commonly used by
routers to evaluate a path?
A. EMI
load, SDLC connections, deterioration rate
B.
Bandwidth, load, reliability
C. Distance,
hub count, SN ratio
D. Signal
count, loss ratio, noise
Question 19:
Which part(s) of an IP address is
used by the router for path determination?
A. Network
B. Network
and client
C. Network,
subnetwork, and host
D. Network,
subnetwork, host, and subnet mask
Question 20:
How are link-state routing updates
triggered?
A. By
timers
B. By
topology changes
C. By
protocol changes
D. By
changing the NIC
Question 21:

the destination network (LAN) of a packet within an internetwork?
A. MAC
address
B. Port
address
C. SPX
address
D. Network
address
Question 22:
Which metric measures the passage of
a data packet through a router?

B. Hop
C.
Transmittal
D.
Signaling
Question 23:
Which best describes link-state algorithms?
A. Enables each router to know the exact
topology of the entire participating internetwork.
B. Requires
minimal router CPU utilization.
C.
Determines distance, direction and reliability to any link on the internetwork.
D. Uses
little network overhead and reduces overall traffic.
Question 24:

update the routing table whenever a topology change occurs
D. Tends to
reveal everything known about an internetwork
