A network administrator needs to isolate traffic between VMs in the same VLAN on a distributed switch. Which feature should be used?
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
✓
Private VLAN
Private VLANs enable isolation between VMs within the same VLAN by dividing the VLAN into primary, isolated, and community sub-VLANs. Option A (Network I/O Control) is used for bandwidth allocation and does not provide traffic isolation. Option C (VLAN trunking) allows multiple VLANs over a single link, not isolation within a VLAN. Option D (Traffic shaping) controls rate limiting, not isolation. Option E (Port binding) determines port membership on a distributed switch, but does not isolate traffic within a VLAN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Network I/O Control
Why it's wrong here
Network I/O Control is used for allocating bandwidth and prioritizing traffic types, not for isolating traffic between VMs.
- ✓
Private VLAN
Why this is correct
Private VLANs allow isolation within a VLAN by defining primary, community, and isolated VLANs, restricting traffic as needed.
- ✗
VLAN trunking
Why it's wrong here
VLAN trunking is used to carry traffic from multiple VLANs across a single link, not to isolate traffic within a VLAN.
- ✗
Traffic shaping
Why it's wrong here
Traffic shaping is for rate limiting and controlling traffic bursts, not for isolation.
- ✗
Port binding
Why it's wrong here
Port binding determines the association of a virtual port to a physical host's pNIC, not traffic isolation.
