Which topology should be recommended?
- A . Full mesh topology
- B . Bus topology
- C . Single-switch topology
- D . Partial mesh topology
What is the effect of implementing link aggregation in an FC SAN environment?
- A . Distributes network traffic over ISLs that ensures even ISL utilization
- B . Yields higher throughput by combing two parallel ISLs into a single physical ISL
- C . Saves bandwidth by restricting traffic to a specific potentially congested ISL
- D . Improves ISL utilization by increasing network traffic on a specific ISL
