Google Professional Cloud Network Engineer Question 609
Select 2Google Cloud PlatformYou are tasked with implementing network packet inspection for your organization's Google Cloud environment to enhance security and ensure compliance. The team wants to inspect packets traversing the network and block malicious traffic while maintaining low latency for critical applications. Which steps should you take to configure network packet inspection effectively using Google Cloud tools?
- A
Deploy a third-party network security appliance through Google Cloud Marketplace that supports packet inspection.
- B
Enable VPC Flow Logs and use Cloud Logging to analyze packet-level details and block unwanted traffic.
- C
Use Google Cloud Armor to inspect and filter packets based on Layer 7 (application layer) policies.
- D
Configure Packet Mirroring to replicate traffic to an analysis tool for deep packet inspection.
- E
Use Firewall Rules in your VPC network to perform stateful packet inspection and block malicious traffic.
Show answer and explanation
Correct answers: A, D
Explanation
To perform network packet inspection in Google Cloud, you need tools or appliances capable of analyzing packets at a granular level. A third-party network security appliance from Google Cloud Marketplace is designed for this purpose and can block malicious traffic effectively. Additionally, Packet Mirroring allows you to replicate network traffic to an analysis tool for deep inspection, which is critical for detecting threats and maintaining security. While other options like VPC Flow Logs, Cloud Armor, and Firewall Rules serve specific security purposes, they do not offer the functionality needed for network packet inspection at the desired level.
- A. Correct.
Deploying a third-party network security appliance from Google Cloud Marketplace is a valid approach to perform deep packet inspection, as these appliances are specialized for this purpose.
- B. Incorrect.
While VPC Flow Logs allow you to monitor and analyze network traffic, they do not provide packet-level inspection capabilities or the ability to block malicious traffic directly.
- C. Incorrect.
Google Cloud Armor is designed for protecting web applications from Layer 7 attacks but does not perform network packet inspection at the packet level.
- D. Correct.
Packet Mirroring enables you to replicate traffic to a third-party tool or appliance for advanced packet inspection and analysis, making it a suitable option for this use case.
- E. Incorrect.
Google Cloud Firewall Rules provide stateful inspection but are not designed for deep packet inspection or complex traffic analysis, focusing instead on access control.
