Google Cloud Certified - Professional Cloud Network Engineer Sample Questions (Q175-Q180):

NEW QUESTION # 175
You are troubleshooting connectivity issues between Google Cloud and a public SaaS provider.
The connectivity between the two environments is through the public internet. Your users are reporting intermittent connection errors when using TCP to connect; however, ICMP tests show no failures. According to users, errors occur around the same time every day. You want to troubleshoot and gather information by using Google Cloud tools that are most likely to provide insights to what is occurring within Google Cloud. What should you do?

A. Enable and review Cloud Logging for Cloud Armor. Look for logs with errors that match the destination IP address of the public SaaS provider.
B. Enable the Firewall Insights API. Set the Deny rule insights observation period to one day.Review Insight results to assure there are no firewall rules denying traffic.
C. Enable and review Cloud Logging on your Cloud NAT Gateway. Look for logs with errors that match the destination IP address of the public SaaS provider.
D. Create a Connectivity Test. Review the results for configuration issues in the VPC routing table.

Answer: C

Explanation:
Enabling Cloud NAT logging surfaces NAT gateway events, like ephemeral port exhaustion or allocation failures, that can disrupt TCP sessions without affecting ICMP. Reviewing those logs for your SaaS provider's destination IP around the error window will reveal whether Cloud NAT is dropping or throttling connections, giving you direct insight into intermittent outbound TCP failures.

NEW QUESTION # 176
You are responsible for enabling Private Google Access for the virtual machine (VM) instances in your Virtual Private Cloud (VPC) to access Google APIs. All VM instances have only a private IP address and need to access Cloud Storage. You need to ensure that all VM traffic is routed back to your on-premises data center for traffic scrubbing via your existing Cloud Interconnect connection. However, VM traffic to Google APIs should remain in the VPC. What should you do?

A. Configure your on-premises router to advertise 0.0.0.0/0 via Border Gateway Protocol (BGP) with a lower priority (MED) than the default VPC route.
Create a private Cloud DNS zone for googleapis.com, create a CNAME for * googieapis.com to private googleapis com, and create an A record for private.googleapis.com that resolves to the addresses in 199 .36.153.8/30.
Create a static route in your VPC for the range 199.36. 153.8/30 with the default internet gateway as the next hop.
B. Delete the default route in your VPC.
Create a private Cloud DNS zone for googleapis.com, create a CNAME for *.googleapis.com to restricted googleapis.com, and create an A record for restricted googleapis com that resolves to the addresses in 199.36.153.4/30.
Create a static route in your VPC for the range 199.36.153.4/30 with the default internet gateway as the next hop.
C. Delete the default route in your VPC and configure your on-premises router to advertise 0.0.0.0/0 via Border Gateway Protocol (BGP).
Create a private Cloud DNS zone for googleapis.com, create a CNAME for * googieapis.com to Private googleapis.com, and create an A record for private.googleapis.com that resolves to the addresses in 199.36.153.8/30.
Create a static route in your VPC for the range 199.36.153.8/30 with the default internet gateway as the next hop.
D. Delete the default route in your VPC and configure your on-premises router to advertise 0.0.0.0/0 via Border Gateway Protocol (BGP).
Create a public Cloud DNS zone with a CNAME for *.google.com to private googleapis com, create a CNAME for * googleapis.com to private googleapis com, and create an A record for Private googleapis.com that resolves to the addresses in 199.36.153 8/30.
Create a static route in your VPC for the range 199 .36.153.8/30 with the default internet gateway as the next hop.

Answer: A

NEW QUESTION # 177
Question:
Your organization is deploying a mission-critical application with components in different regions due to strict compliance requirements. There are latency issues between different applications that reside in us- central1 and us-east4. The application team suspects the Google Cloud network as the source of the excessive latency despite using the Premium Network Service Tier. You need to use Google-recommended practices with the least amount of effort to verify the inter-region latency by investigating network performance. What should you do?

A. Set up the Performance Dashboard in Network Intelligence Center. Select the traffic type (cross-zonal), the metric (latency - RTT), the time period, the desired regions (us-central1 and us-east4), and the network tier.
B. Configure a VM with a probe in Network Intelligence Center in each zone for each region. Choose the traffic type (cross-zonal), metric (latency - RTT), desired regions (us-central1 and us-east4), and the network tier.
C. Enable VPC Flow Logs for the VPC. Identify major bottlenecks from the application level using Flow Analyzer.
D. Configure two Linux VMs in each zone for each region. Install the application, and run a load test using each zone from different regions.

Answer: A

Explanation:
The Performance Dashboard in the Network Intelligence Center provides a detailed view of network latency and performance metrics. For inter-region latency issues, you can quickly identify round-trip times (RTT) and latency using this tool by selecting the specific regions and network tiers, which allows you to diagnose any anomalies or patterns impacting performance.

NEW QUESTION # 178
You have a web application that is currently hosted in the us-central1 region. Users experience high latency when traveling in Asia. You've configured a network load balancer, but users have not experienced a performance improvement. You want to decrease the latency.
What should you do?

A. Configure a policy-based route rule to prioritize the traffic.
B. Configure Dynamic Routing for the subnet hosting the application.
C. Configure the TTL for the DNS zone to decrease the time between updates.
D. Configure an HTTP load balancer, and direct the traffic to it.

Answer: D

NEW QUESTION # 179
You suspect that one of the virtual machines (VMs) in your default Virtual Private Cloud (VPC) is under a denial-of-service attack. You need to analyze the incoming traffic for the VM to understand where the traffic is coming from. What should you do?

A. Enable VPC Flow Logs for the VPC. Analyze the logs and get the source IP addresses from the src_location field.
B. Enable Data Access audit logs of the VPC. Analyze the logs and get the source IP addresses from the subnetworks.get field.
C. Enable Data Access audit logs of the subnet. Analyze the logs and get the source IP addresses from the networks.get field.
D. Enable VPC Flow Logs for the subnet. Analyze the logs and get the source IP addresses from the connection field.

Answer: D

Explanation:
Record network flows sent from and received by VM instances, the best approach would be to use VPC Flow Logs feature. If enabled for a subnet, VPC flow logs collect data from all VM instances in that subnet.
