Google Professional Cloud Network Engineer Exam - Topic 2 Question 104 Discussion

Actual exam question for Google's Professional Cloud Network Engineer exam

Question #: 104
Topic #: 2

[All Professional Cloud Network Engineer Questions]

Your organization has a new security policy that requires you to monitor all egress traffic payloads from your virtual machines in the us-west2 region. You deployed an intrusion detection system (IDS) virtual appliance in the same region to meet the new policy. You now need to integrate the IDS into the environment to monitor all egress traffic payloads from us-west2. What should you do?

AEnable firewall logging and forward all filtered egress firewall logs to the IDS.

BCreate an internal HTTP(S) load balancer for Packet Mirroring, and add a packet mirroring policy filter for egress traffic.

CCreate an internal TCP/UDP load balancer for Packet Mirroring, and add a packet mirroring policy filter for egress traffic.

DEnable VPC Flow Logs. Create a sink in Cloud Logging to send filtered egress VPC Flow Logs to the IDS.

Show Suggested Answer

Suggested Answer: C

Packet Mirroring with an internal TCP/UDP load balancer allows for comprehensive monitoring of egress traffic, which includes payloads. This is required for integration with an IDS for detailed inspection of traffic payloads, meeting the security policy needs for monitoring and detection.

Really? I’m surprised they didn’t mention using a third-party IDS.

I feel like enabling firewall logging might be too basic for this requirement; the IDS integration seems more complex than just forwarding logs.

I practiced a similar question where we had to use packet mirroring, but I can't recall if it was for egress or ingress traffic.

I think enabling VPC Flow Logs could be a good option, but I’m not clear on how to set up the sink to send logs to the IDS.

I remember something about using load balancers for traffic monitoring, but I'm not sure if it should be HTTP(S) or TCP/UDP for this scenario.

Packet Mirroring is the way to go, but I can't decide if I should use HTTP(S) or TCP/UDP. Maybe I should just flip a coin, or ask the IDS for its opinion.
