- A
Set load balancing to 'Route based on IP hash' and make both uplinks active.
Why wrong: IP hash load balancing with active/active provides redundancy if one link fails, but the question asks to ensure failover; active/active also works, but active/standby is more explicit. However, the distracter is plausible but less typical for basic failover.
- B
Enable 'Use explicit failover order' and configure 'Network failures' detection.
Why wrong: This describes failover detection, not the teaming policy itself.
- C
Set load balancing to 'Explicit failover order' and set one uplink as active.
Why wrong: Explicit failover order is not a load balancing policy; it is a part of the teaming configuration but not the primary setting.
- D
Set load balancing to 'Route based on originating virtual port' and make one uplink active and one standby.
This provides clear active/standby failover; if the active uplink fails, standby takes over.
VCP-DCV Configure and Manage vSphere Networking Practice Question
This VCP-DCV practice question tests your understanding of configure and manage vsphere networking. 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.
A vSphere administrator needs to provide redundancy for VM traffic on a vSphere Standard Switch by using multiple physical uplinks. Which teaming configuration should be used to ensure that if one uplink fails, traffic automatically fails over to another?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Set load balancing to 'Route based on originating virtual port' and make one uplink active and one standby.
Option A is correct because 'Route based on originating virtual port' with active/standby failover ensures one uplink is active and the other is standby, with automatic failover. Option B is incorrect because load balancing distributes traffic but doesn't inherently imply failover; however, active/active can also fail over, but the question asks for failover specifically. Option C is incorrect because 'Explicit failover order' is a method, not a load balancing policy. Option D is incorrect because uplink failure detection is a setting, not a policy.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set load balancing to 'Route based on IP hash' and make both uplinks active.
Why it's wrong here
IP hash load balancing with active/active provides redundancy if one link fails, but the question asks to ensure failover; active/active also works, but active/standby is more explicit. However, the distracter is plausible but less typical for basic failover.
- ✗
Enable 'Use explicit failover order' and configure 'Network failures' detection.
Why it's wrong here
This describes failover detection, not the teaming policy itself.
- ✗
Set load balancing to 'Explicit failover order' and set one uplink as active.
Why it's wrong here
Explicit failover order is not a load balancing policy; it is a part of the teaming configuration but not the primary setting.
- ✓
Set load balancing to 'Route based on originating virtual port' and make one uplink active and one standby.
Why this is correct
This provides clear active/standby failover; if the active uplink fails, standby takes over.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
How this comes up in practice
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
Got this wrong? Here's your next step.
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.
