The answer is increasing the buffer-to-buffer credit count on the link, as this is the least likely corrective action for CRC errors on Fibre Channel links. CRC errors typically stem from physical-layer signal integrity issues such as attenuation, dirty connectors, or cable type mismatches, not from flow control or buffer management. On a 16 Gbps link spanning 10 km of dark fiber, high CRC counts point to degraded optical signal quality, which buffer credits cannot address since they only manage frame-level pacing between ports. This question tests your ability to isolate physical-layer faults from upper-layer tuning in a SAN performance analysis, a common trap on the Cisco DCCOR 350-601 exam where candidates mistakenly apply credit adjustments to fix noise-related errors. Remember the mnemonic “CRC = Clean, Right Cable” to recall that cleaning connectors and verifying cable type are the first steps, while credits are for distance, not distortion.
350-601 Storage Network Practice Question
This 350-601 practice question tests your understanding of storage network. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During a SAN performance analysis, a Fibre Channel link shows a high number of CRC errors. The link operates at 16 Gbps over a 10 km dark fiber. Which corrective action is least likely to resolve the issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the buffer-to-buffer credit count on the link.
CRC errors are often due to signal integrity. Option D is least likely because increasing credits does not fix physical layer issues. Option A corrects possible mismatch. Option B can reduce attenuation. Option C proper cleaning.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Increase the buffer-to-buffer credit count on the link.
Why this is correct
Buffer credits affect flow control, not physical errors.
Clue confirmation
The clue word "least" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Replace the fiber cable with a single-mode fiber cable if multimode is used.
Why it's wrong here
Multimode over long distances causes errors.
✗
Clean all fiber connectors and inspect for damage.
Why it's wrong here
Dirty connectors are a common cause of CRC errors.
✗
Verify that the SFP+ optics match the fiber type and distance.
Why it's wrong here
Mismatched optics can cause errors.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-601 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
