Google Cloud Certified - Professional Cloud Network Engineer Sample Questions (Q73-Q78):

NEW QUESTION # 73
You are troubleshooting an issue where your organization's Cloud HA VPN is disconnected from your on- premises router for approximately 10 seconds before reestablishing the tunnel. The issue regularly occurs every few hours. You notice that the HA VPN logs show an entry of Received SA_DELETE when this issue occurs. You need to resolve this issue and prevent future VPN downtime from impacting your production applications. What should you do?

Answer: C

Explanation:
The SA_DELETE message in VPN logs, especially when followed by a re-establishment, is a strong indicator that the Security Association (SA) lifetimes for Phase 1 (IKE SA) or Phase 2 (IPsec SA) are mismatched between the Google Cloud HA VPN and the on-premises router. When one side's SA expires, it sends an SA_DELETE message to the peer, which then triggers a rekeying process. If the lifetimes don't match, one side might prematurely terminate the SA, leading to brief disconnections. Ensuring that the IKE parameters (specifically Phase 1 and Phase 2 lifetimes) match the recommended values in the Cloud HA VPN documentation is crucial for stable tunnel operation.
Exact Extract:
"If your VPN tunnel frequently disconnects and reconnects, and you see SA_DELETE messages in your logs, it often indicates a mismatch in the Phase 1 (IKE SA) and Phase 2 (IPsec SA) lifetimes configured on your on- premises VPN gateway and the Cloud VPN gateway."
"For optimal stability, ensure that the IKE lifetime and ESP/IPsec lifetime parameters on your on-premises VPN device exactly match the recommended values provided in the Cloud VPN documentation. Mismatched lifetimes can cause tunnels to rekey prematurely or fall out of sync, leading to temporary disconnections." Reference: Google Cloud VPN Documentation - Troubleshooting VPN issues, Recommended IKE and IPsec settings


NEW QUESTION # 74
You configured a single IPSec Cloud VPN tunnel for your organization to a third-party customer.
You confirmed that the VPN tunnel is established. However, the BGP session status states that the BGP is not configured. The customer has provided you with their BGP settings:
Local BGP address: 169.254.11.1/30
Local ASN: 64515
Peer BGP address: 169.254.11.2
Peer ASN: 64517
Base MED: 1000
MD5 Authentication: Disabled
You need to configure the local BGP session for this tunnel based on the settings provided by the customer. You already associated the Cloud Router with the Cloud VPN Tunnel. What settings should you use for the BGP session?

Answer: D

Explanation:
To configure the BGP session correctly, you must match the settings provided by the customer and ensure the configuration is reversed when setting up the session on your side:
Local BGP IP and Peer BGP IP:
- The customer's local BGP IP (169.254.11.1) becomes your peer BGP IP.
- The customer's peer BGP IP (169.254.11.2) becomes your local BGP IP.
Local ASN and Peer ASN:
- The customer's local ASN (64515) becomes your peer ASN.
- The customer's peer ASN (64517) becomes your local ASN.
Advertised Route Priority (MED):
- MED provided by the customer is 1000, but this setting is not directly required for the configuration since Google Cloud BGP MED defaults to 100, and it's not explicitly specified to override this.
MD5 Authentication:
- MD5 Authentication is disabled according to the customer's settings, so it should not be enabled.
This configuration ensures that the BGP session settings match the customer's expectations and establishes the session successfully.


NEW QUESTION # 75
You need to establish network connectivity between three Virtual Private Cloud networks, Sales, Marketing, and Finance, so that users can access resources in all three VPCs. You configure VPC peering between the Sales VPC and the Finance VPC. You also configure VPC peering between the Marketing VPC and the Finance VPC. After you complete the configuration, some users cannot connect to resources in the Sales VPC and the Marketing VPC. You want to resolve the problem.
What should you do?

Answer: C

Explanation:
Only directly peered networks can communicate. Transitive peering is not supported. In other words, if VPC network N1 is peered with N2 and N3, but N2 and N3 are not directly connected, VPC network N2 cannot communicate with VPC network N3 over VPC Network Peering.

NEW QUESTION # 76
Question:
Your organization recently exposed a set of services through a global external Application Load Balancer.
After conducting some testing, you observed that responses would intermittently yield a non-HTTP 200 response. You need to identify the error. What should you do? (Choose 2 answers)

Answer: A,C

Explanation:
To identify errors with intermittent non-HTTP 200 responses:
* Enable and review health check logs for your backend to identify potential issues with backend availability or connectivity (Option B).
* Enable logging on the load balancer and review Cloud Logging, particularly the statusDetails field, to gather insights on error types and sources (Option C).
These steps allow for precise error identification by leveraging both health checks and detailed logging features available through Google Cloud's external load balancer diagnostics.

NEW QUESTION # 77
Your company is working with a partner to provide a solution for a customer. Both your company and the partner organization are using GCP. There are applications in the partner's network that need access to some resources in your company's VPC. There is no CIDR overlap between the VPCs.
Which two solutions can you implement to achieve the desired results without compromising the security? (Choose two.)

Answer: B,E

Explanation:
Google Cloud VPC Network Peering allows internal IP address connectivity across two Virtual Private Cloud (VPC) networks regardless of whether they belong to the same project or the same organization.
