the figures represent different ways of configuring a network of physically linked computers labeled p, q, r, and s. a line between two computers indicates that the computers can communicate directly with each other. in which configuration is it not possible to have redundant routing between computers p and s?
Answer
Answer:
B
Explanation:
Step1: Define redundant routing
Redundant routing means multiple paths between two nodes.
Step2: Analyze Option A
There are two paths from P to S (P - Q - S and P - R - S).
Step3: Analyze Option B
There is only one direct path from P to S (P - S), no redundant routing.
Step4: Analyze Option C
There are multiple paths like P - Q - S and P - R - Q - S.
Step5: Analyze Option D
There are multiple paths such as P - Q - S and P - R - S.
