3EF4:0A8A:04B3::74A9:0000::6EF3

Question 2. Eight stations are competing for the use of a shared channel using the 'Adaptive tree Walk Protocol'. If the stations 7 and 8 are suddenly become ready at once, how many bit slots are needed to resolve the contention?

7 slots

5 slots

10 slots

14 slots

Question 3. 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 4. Data link layer retransmits the damaged frames in most networks. If the probability of a frame's being damaged is p, what is the mean number of transmissions required to send a frame if acknowledgements are never lost.

P I (K + 1)

KIK (1 + F)

1/ (1 - F)

K I (K - P)

Question 5. The signal to noise ratio for a voice grade line is 30.1 dB (decibels) or a power ratio of 1023:1. The maximum achievable data rate on this line whose spectrum ranges from 300 Hz to 4300 Hz is

6200 bps

9600 bps

34000 bps

31000 bps

Question 6. What technological progress has allowed the full usage of fiber optics within parallel computer architechture?
I. There are compilers and programming that recognise and exploit parallelism.
II. Widely tunable semiconductor lasers allow maultiple wavelength system.
III. Newly designed operating system for parallel processing.
IV. Migration of architectural features previously found on mainframes onto single-chip microprocessors.

I and III only.

II, III and IV only.

I, II and IV only.

I, II, III and IV.

Question 7. Which Protocol uses port 123?

RPC

NTP

POP3

NNTP

Question 8. Which of the following technique is used for Time-To-Line (TTL)?

a technique used in best-effort delivery system to avoid endlessly looping packets.

a technique used by protocols in which a lower level protocol accepts a message from a higher level protocol and places it in the data portion of the low level frame

One of the pieces that results when an IP gateway divides an IP datagram into smaller pieces for transmission across a network that cannot handle the original datagram size.

all of the above

Question 9. Which of the following technique is used for encapsulation?

a technique used in best-effort delivery systems to avoid endlessly looping packets.

a technique used by protocols in which a lower level protocol accepts a message from a higher level protocol and places it in the data portion of the low level frame.

One of the pieces that results when an IP gateway divides an IP datagram into smaller pieces for transmission across a network that cannot handle the original datagram size

all of the above

Question 10. 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
