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

Question #: 19
Topic #: 1

[All PSE-SoftwareFirewall Questions]

How does a CN-Series firewall prevent exfiltration?

AIt distributes incoming virtual private cloud (VPC) traffic across the pool of VM-Series firewalls.

BIt inspects outbound traffic content and blocks suspicious activity.

CIt provides a license deactivation API key.

DIt employs custom-built signatures based on hash.

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.

C seems irrelevant here, not sure why it's even an option.

A is just about traffic distribution, not exfiltration prevention.

Wait, does a firewall really inspect all outbound traffic? Sounds intense!

I vaguely remember something about distributing traffic, but that seems more related to load balancing than stopping data from leaving the network.

I feel like the answer could also involve custom signatures, but I can't recall if that was more about detecting threats than preventing exfiltration.

I think option B sounds right because it aligns with what we practiced about preventing data leaks by monitoring outgoing traffic.

I remember we discussed how firewalls inspect traffic, but I'm not sure if it's specifically about blocking suspicious outbound traffic.

Hmm, the question mentions "exfiltration," so I'm thinking the firewall must have some kind of advanced threat detection or data loss prevention features to identify and stop that kind of activity.

I'm a bit confused on the difference between the CN-Series and the VM-Series firewalls. I'll need to make sure I understand their specific capabilities before answering this.

Alright, I've got a hunch that the key is in inspecting outbound traffic. That's where you'd typically see exfiltration attempts, so the firewall must have some way to detect and block that.

Okay, let's see. I know the CN-Series firewall is designed for cloud environments, so it's probably got some cloud-specific security features. I'll need to focus on those.

Hmm, this seems like a tricky one. I'll need to think carefully about the different firewall features and how they relate to preventing data exfiltration.

Hmm, B) inspecting outbound traffic, huh? I bet the firewall could also order a pizza and do my laundry while it's at it. Multitasking firewall, nice!
