Google Professional Cloud Network Engineer PROFESSIONAL CLOUD NETWORK ENGINEER Exam Questions in PDF

You have deployed a new internal application that provides HTTP and TFTP services to on-premises hosts. You want to be able to distribute traffic across multiple Compute Engine instances, but need to ensure that clients are sticky to a particular instance across both services.

Which session affinity should you choose?

You created a new VPC network named Dev with a single subnet. You added a firewall rule for the network Dev to allow HTTP traffic only and enabled logging.
When you try to log in to an instance in the subnet via Remote Desktop Protocol, the login fails. You look for the Firewall rules logs in Stackdriver Logging, but you do not see any entries for blocked traffic. You want to see the logs for blocked traffic.

What should you do?

You are trying to update firewall rules in a shared VPC for which you have been assigned only Network Admin permissions. You cannot modify the firewall rules. Your organization requires using the least privilege necessary.

Which level of permissions should you request?

You want to create a service in GCP using IPv6.

What should you do?

You want to deploy a VPN Gateway to connect your on-premises network to GCP. You are using a non BGP- capable on-premises VPN device. You want to minimize downtime and operational overhead when your network grows. The device supports only IKEv2, and you want to follow Google-recommended practices.

What should you do?

Your company just completed the acquisition of Altostrat (a current GCP customer). Each company has a separate organization in GCP and has implemented a custom DNS solution. Each organization will retain its current domain and host names until after a full transition and architectural review is done in one year. These are the assumptions for both GCP environments.

· Each organization has enabled full connectivity between all of its projects by using Shared VPC. · Both organizations strictly use the 10.0.0.0/8 address space for their instances, except for bastion hosts (for accessing the instances) and load balancers for serving web traffic. · There are no prefix overlaps between the two organizations. · Both organizations already have firewall rules that allow all inbound and outbound traffic from the 10.0.0.0/8 address space.

· Neither organization has Interconnects to their on-premises environment.

You want to integrate networking and DNS infrastructure of both organizations as quickly as possible and with minimal downtime.

Which two steps should you take? (Choose two.)

Your on-premises data center has 2 routers connected to your Google Cloud environment through a VPN on each router. All applications are working correctly; however, all of the traffic is passing across a single VPN instead of being load-balanced across the 2 connections as desired.

During troubleshooting you find:

· Each on-premises router is configured with a unique ASN.
· Each on-premises router is configured with the same routes and priorities. · Both on-premises routers are configured with a VPN connected to a single Cloud Router. · BGP sessions are established between both on-premises routers and the Cloud Router. · Only 1 of the on-premises router's routes are being added to the routing table.

What is the most likely cause of this problem?

You have ordered Dedicated Interconnect in the GCP Console and need to give the Letter of Authorization/ Connecting Facility Assignment (LOA-CFA) to your cross-connect provider to complete the physical connection.

Which two actions can accomplish this? (Choose two.)
