Networking in Computer Science

The section contains multiple choice questions and answers on networking in computer science, which refers to interconnected computing devices that can exchange data and share resources with each other. These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies

Consider a situation in which you are a system administrator on a NetWare network, you are running NetWare 4.11 and you cannot communicate with your router. What is the likely problem?

NetWare 4.11 defaults to 802.2 encapsulation NetWare 4.11 defaults to 802.3 encapsulation Cisco routers only work with NetWare 3.11 NetWare 3.11 defaults to 802.2 encapsulation

NetWare IPX addressing uses a network number and a node number. Which statement is not true?

The network address is administratively assigned and can be up to 16 hexadecimal digits long The node address is always administratively assigned The node address is usually the MAC address If the MAC address is used as the node address, then IPX eliminates the use of ARP

What does the following series of commands “Router IGRP 71 network” accomplish? 10.0.0.0 router IGRP 109 network 172.68.7.0

It isolates networks 10.0.0.0 and 172.68.7.0 It loads IGRP for networks 109 and 71 It disables RIP It disables all routing protocols

The “IPX delay number” command will allow an administrator to change the default settings. What are the default settings?

For LAN interfaces, one tick; for WAN interfaces, six ticks For LAN interfaces, six ticks; for WAN interfaces, one tick For LAN interfaces, zero ticks; for WAN interfaces, five ticks For LAN interfaces, five ticks; for WAN interfaces, zero Ticks

By default, Cisco routers forward GNS SAPs to remote networks.

False True
