Q.51: Which of the following
Q.51: Which of the following is not a palindromic subsequence of the string "ababcdabba"?
Options:
1. abcba
2. abba
3. abbbba
.4 adba
Official Answer: 4. adba
Explanation: A palindromic sequence is one that reads the same backward as forward. In the context of genetics, which deals with sequences of nucleotides, a palindrome is a sequence of nucleotides that is the same as its reverse complement. Applying this definition more broadly to any string of characters, options 1 (abcba), 2 (abba), and 3 (abbbba) are palindromes as their sequences remain unchanged when reversed. Option 4 (adba), however, is not the same when reversed (abda), making it the correct non-palindromic sequence.
Q.52: Which of the following is not a field in TCP header?
Options:
1. Sequence Number
2. Checksum
3. Fragmentation offset
4. Window size
Official Answer: 3. Fragmentation offset
Explanation: The TCP header contains various fields such as Sequence Number, Checksum, and Window size, which are used for establishing and managing a TCP connection. The Fragmentation offset is not included in the TCP header; it is a part of the IP header used for the fragmentation and reassembly of packets.
Q.53: Which of the following are examples of CSMA channel sensing methods?
Options:
1. 1-persistent
2. 2-persistent
3. p-persistent
4. o-persistent
Official Answer: 2. (A), (C) and (D) Only
Explanation: The three types of CSMA access modes are:
1-persistent CSMA
Non-persistent CSMA
P-persistent CSMA
O-persistent is a mode of Carrier Sense Multiple Access (CSMA) that determines the superiority of a station before data transmission. In this mode, if the channel is inactive, all stations will wait to transmit data in turn.
Carrier Sense Multiple Access (CSMA) is a network protocol that listens to a network channel before transmitting on it. The sensing methods include:
1-persistent CSMA: Transmits immediately upon finding the channel idle.
p-persistent CSMA: Uses a probabilistic approach to transmitting when the channel is found idle.
o-persistent CSMA: Not a standard term in CSMA methods, it seems to be a typographical error.
The term "2-persistent" is not a recognized standard method in CSMA, which makes options (A), (C), and (D) correct according to the official answer. However, there seems to be a mistake because "o-persistent" is not a recognized term. This might require further clarification.
