3.A-II, B-IV, C-III, D-I
4.A-IV, B-III, C-I, D-II
Solution
The Correct Answer is: Option 2
Explanation of Each Option:
A. Count to infinity problem - Distance vector routing:
The "Count to infinity problem" is a well-known issue in distance vector routing protocols.
In distance vector routing, routers exchange information about the distance to different networks. If a link fails, routers may continuously increase their distance metric, leading to a slow convergence problem known as "count to infinity."
Thus, the correct match is A-II.
B. IEEE 802.16 - WIMAX:
IEEE 802.16 is a set of standards for wireless broadband access systems, commonly referred to as WiMAX (Worldwide Interoperability for Microwave Access).
WiMAX provides high-speed internet access over long distances and is commonly used in metropolitan areas and rural regions.
Thus, the correct match is B-III.
C. IEEE 802.15 - Bluetooth:
IEEE 802.15 is the standard for Wireless Personal Area Networks (WPAN), which includes Bluetooth technology.
Bluetooth is a short-range communication technology used for exchanging data between devices such as smartphones, laptops, and headphones.
Thus, the correct match is C-IV.
D. AODV protocol - Mobile Adhoc Networks:
AODV (Ad-hoc On-Demand Distance Vector) routing protocol is specifically designed for Mobile Ad Hoc Networks (MANETs).
It is a reactive routing protocol, meaning that it establishes routes only when required, reducing unnecessary overhead in dynamic and decentralized MANET environments.
