Matching Network Protocols and Problems
This section explains the correct matching between the items listed in List I and List II, focusing on networking concepts and standards.
Understanding the Matches
We need to connect each item from List I (A, B, C, D) to its corresponding item in List II (I, II, III, IV).
A. Count to infinity problem and Distance vector routing
The Count to infinity problem is a well-known issue associated with Distance vector routing protocols. This problem arises when routing loops occur, causing routing update messages to circulate indefinitely, making the path cost appear infinite. Therefore, A matches with II.
B. IEEE 802.16 and WIMAX
IEEE 802.16 is a set of standards for Wireless Metropolitan Area Networks (WMANs). The most prominent implementation and commercial name associated with this standard is WIMAX (Worldwide Interoperability for Microwave Access), which provides broadband wireless access. Thus, B matches with III.
C. IEEE 802.15 and Bluetooth
The IEEE 802.15 standard specifies protocols for Wireless Personal Area Networks (WPANs). Bluetooth technology, designed for short-range communication between devices like phones, headphones, and computers, operates under this standard. Therefore, C matches with IV.
D. AODV protocol and Mobile Adhoc Networks
The AODV (Ad hoc On-Demand Distance Vector) protocol is a routing protocol specifically designed for use in Mobile Adhoc Networks (MANETs). It allows nodes to discover routes only when needed, making it efficient for dynamic network environments. Hence, D matches with I.
Summary of Matches
Here is a summary table showing the correct pairings:
| List I Item | Description | List II Item | Matching Description |
|---|---|---|---|
| A. Count to infinity problem | A routing loop issue | II. Distance vector routing | A type of routing protocol |
| B. IEEE 802.16 | Wireless MAN standard | III. WIMAX | Broadband wireless standard |
| C. IEEE 802.15 | Wireless PAN standard | IV. Bluetooth | Short-range wireless technology |
| D. AODV protocol | Routing protocol | I. Mobile Adhoc Networks | Network type |
Correct Option Determination
Based on the individual matches derived above:
- A matches with II
- B matches with III
- C matches with IV
- D matches with I
This combination corresponds to the correct answer.
