VCP-DCV vSphere Architecture, Products and Solutions Practice Question
A company's vSphere environment consists of four ESXi hosts, each with two 10 GbE physical NICs. The administrator configures a VDS with two dvUplinks and uses load-balancing policy 'Route based on IP hash'. To use IP hash, what additional configuration is required on the physical switches?
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
✓
Configure link aggregation (LACP or static EtherChannel) on the switch ports
IP hash requires link aggregation (either LACP or static EtherChannel) to be configured on the physical switch ports to ensure proper hashing and load balancing. Option A is incorrect because VLAN trunking is a separate configuration and not directly required for IP hash. Option B is incorrect because configuring LACP on the VDS uplink port groups is optional and not mandatory for IP hash; the necessary link aggregation must be done on the physical switches. Option D is incorrect because IGMP snooping is used for managing multicast traffic and is not related to IP hash load balancing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable VLAN trunking on the switch ports
Why it's wrong here
VLAN trunking is needed for VLANs but not specific to IP hash.
- ✗
Configure LACP on the VDS uplink port groups
Why it's wrong here
LACP can be used on VDS, but the physical switch must also be configured; the question asks for additional configuration on physical switches.
- ✓
Configure link aggregation (LACP or static EtherChannel) on the switch ports
Why this is correct
IP hash load balancing requires an aggregated link on the physical switch side.
- ✗
Enable IGMP snooping on the switch
Why it's wrong here
IGMP snooping is for multicast traffic, not load balancing.
