Designing Cisco Data Center Infrastructure (DCID, legacy) — Question 46
Which two options are benefits of credit-based flow control in a Fibre Channel network? (Choose two.)
Answer options
- A. sends credit to all of the switches in a SAN zone
- B. increases the credit limit when the buffer overruns
- C. maximizes performance under high loads
- D. prevents the loss of frames due to buffer overruns
- E. provides automatic buffer scaling under high loads
Correct answer: D, E
Explanation
Option D is correct because credit-based flow control effectively prevents frame loss by managing buffer usage. Option E is also correct as it allows for automatic adjustments to the buffer size to accommodate higher loads. The other options do not accurately describe the benefits of credit-based flow control in a Fibre Channel network.
