Welcome to Networking Quiz, Randomly Selected !!

Question 1. The communication mode that supports two-way traffic but only one direction at a time is

simplex

duplex

multiplex

half-duplex

Question 2. How can you see the address of the DHCP server from which a client received its IP address?

By using Advanced Properties of TCP/IP

By using IPCONFIG/ALL

By using DHCPINFO

By pinging DHCP

Question 3. A network consists of eight NT servers. You are planning to move servers to different segments of your network, what utility should be used at each server to determine which server generates the most traffic?

NBTSTAT.EXE

Performance Monitor

Network Monitor

ARP.EXE

Question 4. On a class B network, how many hosts are available at each site with a subnet mask of 248?

16,382

8,190

4,094

2,046

Question 5. In CRC there is no error if the remainder at the receiver is ----.

equal to the remainder at the sender

zero

non-zero

the quotient at the sender

Question 6. Which of the following refers to the terms "residual error rate"?

the number of bit errors per twenty four hours of continuous operation on an asynchronous line

The probability that one or more errors will be undetected when an error detection scheme is used

the probability that one or more errors will be detected when an error detection mechanism is used

signal to noise ratio divided by the ratio of energy per bit to noise per hertz

Question 7. Which of the following statement is incorrect?

The Addresses Resolution Protocol, ARP, allows a host to find the physical address of a target host on the same physical network, given only the target IP address.

The sender's IP - to- physical address binding is included in every ARP broadcast; receivers update the IP-to-Physical address binding information in their cache before processing an ARP packet.

ARP is a low-level protocol that hides the underlying network physical addressing, permitting us to assign IP-addresses of our choice to every machine.

all of the above

Question 8. What device separates a single network into two segments but lets the two segments appear as one to higher protocols?

switch

bridge

Gateway

Router

Question 9. The packets switching concept was first proposed

in the late 1980s for the Defense Ministry of US.

in the early 1960s for military communication systems, mainly to handle speech

in the late 1950s for Defense Ministry of US

none of the above

Question 10. What is the default subnet mask for a class C network?

127.0.0.1

255.0.0.0

255.255.255.0

255.255.0.0
