 Field Length in bits P. UDP Header’s Port Number I. 48 Q. Ethernet MAC Address II. 8 R. IPv6 Next Header III. 32 S. TCP Header’s Sequence Number IV. 16

• A

P-III, Q-IV, R-II, S-I  • B

P-II, Q-I, R-IV, S-III  • C

P-IV, Q-I, R-II, S-III  • D

P-IV, Q-I, R-III, S-II  • Option : C
• Explanation :
UDP Header’s Port Number ⟹ 16 bit
Ethernet MAC Address ⟹ 48 bit
IPv6 Next Header ⟹ 8 bit
TCP Header’s Sequence Number ⟹ 32 bit

• A

(D - M)/(X - M)  • B

(X - M)/(D - M)  • C

(D - X)/(D - M)  • D

(X - M)/(D - X)  • Option : B
• Explanation :
EMAT = P * S + (1 - P) * M
X = P * D + (1 - P) * M
X = P * D + M - P * M
X - M = P (D - M)
P = (X - M)/(D - M)

• A

Query 1  • B

Query 2  • C

Query 3  • D

Query 4  • Option : D
• Explanation :
In the given Query 4 is full outer join so that full order join record set superset of records compare to inner join, left outer join & right outer join.

• A

Only ii and iii are true  • B

Only i and iii are true  • C

Only iv is true  • D

Only i and iv are true  • Option : C
• Explanation :
cwnd is approximately doubles every round-trip time. So option C is the correct answer.

• A

QPTRS  • B

PTRSQ  • C

TRPQS  • D

QTPRS  • Option : A
• Explanation :
The Sequence is Processor required to handle the interrupt is :
Q. Processor finishes the execution of the current instruction.
P. Processor pushes the process status of L onto the control stack.
T. Processor loads the new PC value based on the interrupt.
R. Processor executes the interrupt service routine.
S. Processor pops the process status of “L” from the control stack.
