You need to restrict access to your Google Cloud load-balanced application so that only specific IP addresses can connect. What should you do?

Your end users are located in close proximity to us-east1 and europe-west1. Their workloads need to communicate with each other. You want to minimize cost and increase network efficiency. How should you design this topology?

Your organization is deploying a single project for 3 separate departments. Two of these departments require network connectivity between each other, but the third department should remain in isolation. Your design should create separate network administrative domains between these departments. You want to minimize operational overhead. How should you design the topology?

You are migrating to Cloud DNS and want to import your BIND zone file. Which command should you use?

You created a VPC network named Retail in auto mode. You want to create a VPC network named Distribution and peer it with the Retail VPC. How should you configure the Distribution VPC?

You are using a third-party next-generation firewall to inspect traffic. You created a custom route of 0.0.0.0/0 to route egress traffic to the firewall. You want to allow your VPC instances without public IP addresses to access the BigQuery and Cloud Pub/Sub APIs, without sending the traffic through the firewall. Which two actions should you take? (Choose two.)

All the instances in your project are configured with the custom metadata enable-oslogin value set to FALSE and to block project-wide SSH keys. None of the instances are set with any SSH key, and no project-wide SSH keys have been configured. Firewall rules are set up to allow SSH sessions from any IP address range. You want to SSH into one instance. What should you do?

You work for a university that is migrating to GCP. These are the cloud requirements: "¢ On-premises connectivity with 10 Gbps "¢ Lowest latency access to the cloud "¢ Centralized Networking Administration Team New departments are asking for on-premises connectivity to their projects. You want to deploy the most cost-efficient interconnect solution for connecting the campus to Google Cloud. What should you do?

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.)

Your company offers a popular gaming service. Your instances are deployed with private IP addresses, and external access is granted through a global load balancer. You believe you have identified a potential malicious actor, but aren't certain you have the correct client IP address. You want to identify this actor while minimizing disruption to your legitimate users. What should you do?

Your company's web server administrator is migrating on-premises backend servers for an application to GCP. Libraries and configurations differ significantly across these backend servers. The migration to GCP will be lift-and-shift, and all requests to the servers will be served by a single network load balancer frontend. You want to use a GCP-native solution when possible. How should you deploy this service in GCP?

You decide to set up Cloud NAT. After completing the configuration, you find that one of your instances is not using the Cloud NAT for outbound NAT. What is the most likely cause of this problem?

You want to set up two Cloud Routers so that one has an active Border Gateway Protocol (BGP) session, and the other one acts as a standby. Which BGP attribute should you use on your on-premises router?
