Palo Alto Networks Exam PSE-SoftwareFirewall Topic 4 Question 11 Discussion

Actual exam question for Palo Alto Networks's PSE-SoftwareFirewall exam

Question #: 11
Topic #: 4

A customer in a VMware ESXi environment wants to add a VM-Series firewall and partition an existing group of virtual machines (VMs) in the same subnet into two groups. One group requires no additional security, but the second group requires substantially more security.

How can this partition be accomplished without editing the IP addresses or the default gateways of any of the guest VMs?

AEdit the IP address of all of the affected VMs.

BCreate a new virtual switch and use the VM-Series firewall to separate virtual switches using virtual wire mode. Then move the guests that require more security into the new virtual switch.

CSend the VLAN out of the virtual environment into a hardware Palo Alto Networks firewall in Layer 3 mode. Use the same IP address as the old default gateway, then delete it.

DCreate a Layer 3 interface in the same subnet as the VMs and then configure proxy Address Resolution Protocol (ARP).

Show Suggested Answer

Suggested Answer: B

Creating a New Virtual Switch:

By creating a new virtual switch, you can segment the network within the ESXi environment. The VM-Series firewall can then be used to provide security controls between these virtual switches using virtual wire mode.

Moving Guests to New Virtual Switch:

Guests requiring additional security are moved to the new virtual switch, allowing the VM-Series firewall to inspect and control traffic between the switches. This setup does not necessitate changes to the existing IP addresses or default gateways of the VMs.

Haha, editing all the IP addresses? That's a hard pass for me, option A is way too much work.

I think option B is a more efficient way to achieve the partition without changing IP addresses.

Agreed, option A sounds like a lot of manual work.

I agree with Anastacia. Option B seems like the most efficient way to achieve the partitioning we need.

D is interesting, using proxy ARP to handle the partition without IP address changes. Definitely worth considering.

I think option B is the best choice. It allows us to separate the VMs without changing their IP addresses.
