Drag and Drop Question Drag and drop the characteristics from the left onto the routing protocols they describe on the right. Answer:
The correct answer is Dual Diffusing Update algorithm; metrics are bandwidth, delay, reliability, load, and MTU; cost-based metric; Dijkstra algorithm. EIGRP (Enhanced Interior Gateway Routing Protocol) uses the Dual Diffusing Update Algorithm (DUAL) for loop-free path selection and calculates routes using composite metrics including bandwidth, delay, reliability, load, and MTU. OSPF (Open Shortest Path First) uses Dijkstra's…

Answer Area
Drag items
Correct arrangement
- Dual Diffusing Update algorithm
- metrics are bandwidth, delay, reliability, load, and MTU
- cost-based metric
- Dijkstra algorithm
Explanation
EIGRP (Enhanced Interior Gateway Routing Protocol) uses the Dual Diffusing Update Algorithm (DUAL) for loop-free path selection and calculates routes using composite metrics including bandwidth, delay, reliability, load, and MTU. OSPF (Open Shortest Path First) uses Dijkstra's Shortest Path First (SPF) algorithm and employs a cost-based metric derived from interface bandwidth. These pairings reflect the fundamental algorithmic and metric distinctions between these two major routing protocols.
