between a pair of vertices is ½. What is the expected number of unordered cycles of length
three?
(A) 1/8 (B) 1 (C) 7 (D) 8
Answer:-(C)

Q: Sum of degrees of all vertices is even.
(A) P only (B) Q only
(C) Both P and Q (D) Neither P nor Q
Answer:- (C)


8. Which of the following statements are TRUE?
(1) The problem of determining whether there exists a cycle in an undirected graph is in P.
(2) The problem of determining whether there exists a cycle in an undirected graph is in NP.
(3) If a problem A is NP-Complete, there exists a non-deterministic polynomial time
algorithm to solve A.
(A) 1,2 and 3 (B) 1 and 2 only (C) 2 and 3 only (D) 1 and 3 only
Answer: -(A)

(4) Turing recognizable languages are closed under union and intersection.
(A) 1 and 4 only (B) 1 and 3 only (C) 2 only (D) 3 only
Answer: -(C)

11. An index is clustered, if
(A) it is on a set of fields that form a candidate key
(B) it is on a set of fields that include the primary key
(C) the data records of the file are organized in the same order as the data entries of the index
(D) the data records of the file are organized not in the same order as the data entries of the
index

Answer:- (C)

16. A scheduling algorithm assigns priority proportional to the waiting time of a process. Every
process starts with priority zero(the lowest priority). The scheduler re-evaluates the process
priorities every T time units and decides the next process to schedule. Which one of the
following is TRUE if the processes have no I/O operations and all arrive at time zero?
(A) This algorithm is equivalent to the first-come-first-serve algorithm
(B) This algorithm is equivalent to the round-robin algorithm
(C) This algorithm is equivalent to the shortest-job-first algorithm
(D) This algorithm is equivalent to the shortest-remaining-time-first algorithm
Answer:-(B)
