What is the standard ethernet cabling specification? (not
IEEE 802.3)
A. STP
B. Coax (thin)
C. Coax (thick)
D. UTP
Answer / guest
Answer: C
Ethernet was created by Xerox in the 1970?s and IEEE 802.3
was developed in 1980. Standard ethernet cabling is 50 ohm
coax (thick) and IEEE 802.3 specifications include coax
(thick or thin), UTP, and Fiber Optic.

Match the following devices with the correct description. A. Switch 1. Operates at the physical layer and extends the cable as if it is a single cable. B. Router 2. Operates at the physical layer and connects all connections into one device or concentrator. C. Repeater 3. Operates at the network layer and can filter both hardware and network addresses. D. Hub 4. Works at the Data-Link layer and transmits a digital signal only to the specific port where the destination MAC address is located.
How is data transmitted in a Token Ring network? A. The node calls for a token, appends the data, modifies a bit in the frame, then sends the token B. The node waits for the token, gains possession of it, appends the data, modifies a bit in the frame, then sends the token C. The node transmits the data whenever it wants to D. The active monitor must first grant permission for the node to transmit data. After it receives permission, it sends the data
Which of the following three protocols replace SDLC? A. 802.2 B. HDLC C. QLLC D. X.25
What protocol advertises Netware services to network clients? (Type acronym).
What is an advantage of CHAP over PAP? A. Passwords are stored on separate servers in encrypted form B. CHAP sends passwords unencrypted to save connection time C. CHAP does not attempt to verify whether the user is authorized to access the requested resource D. ID?s and passwords are automatically stored in cache
What is the first step in diagramming packet flow for the terminals within a network? A. Identify the end user nodes of all the terminals B. Figure out the speed of all the servers C. Find out where all the routers are located D. Find out where all the switched are located
When is the route to a node determined in an SRB (Source Route Bridging) Token Ring network? A. Before any data is transmitted B. After the data is transmitted C. During the transmission of data D. After the first frame is transmitted
What are two services that DUAL (Diffusing Update Algorithm) performs for EIGRP? A. Provides loop-free operation throughout an entire route?s computation B. Simultaneous synchronization of routers involved in a topology change C. Updates the autonomous system number D. Allows advertised distances to use feasible distances
EIGRP was developed to improve what two protocols? A. OSPF B. RIP C. BGP D. IGRP
Distance Vector and Link-State protocols converge more quickly if: A. there is router redundancy B. there is router redistribution C. the update interval is set to its maximum D. the whole routing table is sent to announce changes
Regarding a full-mesh network and a partial-mesh network, what is the most accurate statement? A. Split Horizon will not work on a full-mesh network B. A full-mesh network is more expensive because more routers are used C. A partial-mesh network is less expensive because less virtual circuits are used D. Broadcasts are more plentiful on a partial-mesh network
Which of the following are true regarding switched virtual circuits (SVCs) and permanent virtual circuits (PVCs)? Choose two. A. SVCs and PVCs can use the same circuit. B. PVCs are permanently established virtual circuits. C. SVCs and PVCs terminate the circuit when data transmission is complete. D. SVCs are virtual circuits that are dynamically established on demand and terminated when data transmission is complete.
