HPE7-A07 Exam - Topic 1 Question 16 Discussion

A customer is running out of IP addresses in a network segment. What will happen If they add an additional IPsubnet to the same VLAN?
D) Users can reach each other and establish PTP traffic without passing an L3 point in the same VLAN
A) Broadcasts for me two subnets win arrive on all ports in the same VLAN
B) IGMP will not work in both of the subnets in the same VLAN
C) This would result in a single SVI using two subinterfaces.

[All HPE7-A07 Questions]

A customer is running out of IP addresses in a network segment. What will happen If they add an additional IPsubnet to the same VLAN?

Show Suggested Answer Hide Answer
Suggested Answer: D

Adding an additional IP subnet to the same VLAN means that devices configured with either subnet can communicate at Layer 2 without the need for routing. This is because they are on the same VLAN and thus in the same broadcast domain. However, to communicate between subnets, an L3 device or inter-VLAN routing would be required.

Users can still communicate without L3? That's interesting!

I feel like users should still be able to communicate without routing, but I’m not clear on how adding a subnet affects that.

If I remember correctly, having multiple subnets in the same VLAN could lead to broadcast storms, but I'm not entirely certain.

Ah, I see. If we add a new subnet to the same VLAN, we could end up with a single SVI using multiple subinterfaces. That's an important consideration.

Interesting. I wonder if users would be able to reach each other directly within the same VLAN without going through a Layer 3 point. I'll need to think that through.

This is a tricky one. I'm not super familiar with all the tools mentioned, so I'll need to do a quick review to make sure I understand the capabilities of each. But I'm confident I can figure out the best approach once I've looked into it a bit more.

Wait, does that mean they're running out of IP addresses because they're using the same VLAN for everything? That's like using a single room for a whole family reunion!

I'm not sure about B, as IGMP is used for multicast, and having multiple subnets in the same VLAN shouldn't affect that.

Option A seems logical, as adding a new subnet to the same VLAN would cause broadcasts to be forwarded to all ports in that VLAN.
