Quick Answer
The answer is the Round Robin path selection policy (VMW_PSP_RR). This is correct because the Round Robin policy actively distributes I/O requests across all available active paths in a cyclic order, which maximizes aggregate throughput by fully utilizing the bandwidth of every path to the Fibre Channel storage array. On the VMware Certified Professional Data Center Virtualization VCP-DCV exam, this question tests your understanding of multipathing policies for performance optimization, often appearing as a scenario where an administrator needs to balance load rather than maintain path redundancy. A common trap is confusing Fixed (VMW_PSP_FIXED), which pins traffic to a single preferred path, or Most Recently Used (MRU), which only uses one path until failure—both of which limit throughput. Remember the memory tip: "Round Robin rotates, so throughput never stagnates."
This VCP-DCV practice question tests your understanding of configure and manage vsphere storage. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
An administrator is configuring multipathing for a Fibre Channel storage array. The administrator wants to maximize throughput by using all available paths. Which path selection policy should be chosen?
Fixed (VMW_PSP_FIXED)
Why wrong: Incorrect: Fixed uses a single path, not all paths.
Most Recently Used (VMW_PSP_MRU)
Why wrong: Incorrect: MRU uses one path at a time.
Vendor-specific (VMW_PSP_FIXED_AP)
Why wrong: Incorrect: FIXED_AP also uses a single preferred path.
Round Robin (VMW_PSP_RR)
Correct: Round Robin spreads I/O across all active paths, maximizing throughput.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Round Robin (VMW_PSP_RR)
Round Robin policy distributes I/O across all active paths, maximizing throughput. Option B is incorrect because Fixed uses a single preferred path. Option C is incorrect because Most Recently Used (MRU) uses one path until failure. Option D is incorrect because VMW_PSP_FIXED is essentially Fixed.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Fixed (VMW_PSP_FIXED)
Why it's wrong here
Incorrect: Fixed uses a single path, not all paths.
Most Recently Used (VMW_PSP_MRU)
Why it's wrong here
Incorrect: MRU uses one path at a time.
Vendor-specific (VMW_PSP_FIXED_AP)
Why it's wrong here
Incorrect: FIXED_AP also uses a single preferred path.
Round Robin (VMW_PSP_RR)
Why this is correct
Correct: Round Robin spreads I/O across all active paths, maximizing throughput.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related VCP-DCV NAT questions on configuration and troubleshooting.
