both a and b
none of the given
Constant Byte Rate

Question # 2 of
The routing table in interior and exterior switches has which one of the following?
It should have next hop for each possible destination
The next hop in table must be on shortest path to destination
Both (a) and (b)
None of the above
Question # 3 of 10
Which one of the following is a method for computing routing table information?
Manual entry
Static routing
Boot time routing
None of the above
How to compute routing table information:
Static routing - at boot time
Dynamic routing - allow automatic updates by a program
Question # 4 of 10
Which one of the following is the responsibility of Djikstra’ algorithm?
To compute the shortest path between two nodes
To extract next hop information from path information
To insert next hop information into routing table
All of the above
While computing shortest path, first we assume graph representation of network
at each node then we use Djikstra’s algorithm to compute shortest path from each node to
every other node. Then extract next hop information from resulting path information and
insert next hop information into routing tables.
Question # 5 of 10
Routing table is used to keep the information about…………….
Destination
Medium of transmission
Routers used in network
All of the above
The routing table contains list of destination networks and next hop for each destination.
Question # 6 of 10 ( Start time: 04:48:43 PM ) Total M - 1
Frame relay is………………….
Connection oriented service
Connectionless service
It is typically ranges from 5Mbps to 1000Mbps.
None of the above
It is used for Telco service for delivering blocks of data. It is connection based
service and must contract with Telco for circuit between two endpoints. It is typically
56kbps or 1.5Mbps and can run to 100Mbps.
Question # 7 of 10 ( Start time: 04:49:43 PM ) Total M - 1
Which of the following is not a guided medium?
Twisted-pair cable
Fiber-optic cable
Atmosphere
Coaxial cable
Question # 8 of 10
Which of the following statement is wrong regarding PVC?
PVC last as long as the customer pay the periodic fee for its use.
Forwarding tables are automatically restored after pow er of equipment failure.
Forwarding table entries for PVC’s are dynamically configured.
All of the above are wrong
ATM can provide customers with virtual circuits that look like traditional leased
digital circuits. Such permanent virtual circuits (PVC) last as long as the customer pay
the periodic fee for its use. The forwarding tables are automatically restored after power
of equipment failure. The forwarding table entries for such permanent VC’s are statically
configured, the terms used by Telco’s for this is provisioning
Question # 9 of 10
Which of the following statement is true regarding ATM?
Select correct option:
ATM is a single technology that is designed to meet the goals of both LANs and WANs.
ATM uses the concept of connection-oriented networking.
Both (a) and (b)
None of the above
ATM is a single technology that is designed
to meet the goals of both LANs and WANs.
ATM uses the concept of connection-oriented networking
Question # 10 of 10
Djikstra’s algorithm is used to compute the……………….
shortest path between two nodes
number of nodes used in the network
distance between different nodes
none of the above
While computing shortest path, first we assume graph representation of network
at each node then we use Djikstra’s algorithm to compute shortest path from each node to
every other node. Then extract next hop information from resulting path information and
insert next hop information into routing tables.
