Question 1

You are migrating a three-tier application architecture from on-premises to Google Cloud. As a first step in the migration, you want to create a new Virtual Private Cloud (VPC) with an external HTTP(S) load balancer. This load balancer will forward traffic back to the on-premises compute resources that run the presentation tier. You need to stop malicious traffic from entering your VPC and consuming resources at the edge, so you must configure this policy to filter IP addresses and stop cross-site scripting (XSS) attacks. What should you do?

A : Create a Google Cloud Armor policy, and apply it to a backend service that uses an unmanaged instance group backend.

B : Create a hierarchical firewall ruleset, and apply it to the VPC's parent organization resource node.

C : Create a Google Cloud Armor policy, and apply it to a backend service that uses an internet network endpoint group (NEG) backend.

D : Create a VPC firewall ruleset, and apply it to all instances in unmanaged instance groups.

Answer: C

Question 2

You want to create a service in GCP using IPv6.

What should you do?

A : eate the instance with the designated IPv6 address.

B : nfigure a TCP Proxy with the designated IPv6 address.

C : nfigure a global load balancer with the designated IPv6 address.

D : nfigure an internal load balancer with the designated IPv6 address.

Answer: C

Question 3

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 costefficient interconnect solution for connecting the campus to Google Cloud. What should you do?

A : Use Shared VPC, and deploy the VLAN attachments and Interconnect in the host project.

B : Use Shared VPC, and deploy the VLAN attachments in the service projects. Connect the VLAN attachment to the Shared VPC's host project.

C : Use standalone projects, and deploy the VLAN attachments in the individual projects. Connect the VLAN attachment to the standalone projects' Interconnects.

D : Use standalone projects and deploy the VLAN attachments and Interconnects in each of the individual projects.

Answer: A

Question 4

Your company has 10 separate Virtual Private Cloud (VPC) networks, with one VPC per project in a single region in Google Cloud. Your security team requires each VPC network to have private connectivity to the main on-premises location via a Partner Interconnect connection in the same region. To optimize cost and operations, the same connectivity must be shared with all projects. You must ensure that all traffic between different projects, on-premises locations, and the internet can be inspected using the same third-party appliances. What should you do?

A : Configure the third-party appliances with multiple interfaces and specific Partner Interconnect VLAN attachments per project. Create the relevant routes on the third-party appliances and VPC networks.

B : Configure the third-party appliances with multiple interfaces, with each interface connected to a separate VPC network. Create separate VPC networks for on- premises and internet connectivity. Create the relevant routes on the third-party appliances and VPC networks.

C : Consolidate all existing projects’ subnetworks into a single VPC. Create separate VPC networks for onpremises and internet connectivity. Configure the third-party appliances with multiple interfaces, with each interface connected to a separate VPC network. Create the relevant routes on the third-party appliances and VPC networks.

D : Configure the third-party appliances with multiple interfaces. Create a hub VPC network for all projects, and create separate VPC networks for on-premises and internet connectivity. Create the relevant routes on the third-party appliances and VPC networks. Use VPC Network Peering to connect all projects’ VPC networks to the hub VPC. Export custom routes from the hub VPC and import on all projects’ VPC networks.

Answer: D

Question 5

Your organization wants to set up hybrid connectivity with VLAN attachments that terminate in a single Cloud Router with 99.9% uptime. You need to create a network design for your on-premises router that meets those requirements and has an active/passive configuration that uses only one VLAN attachment at a time. What should you do?

A : Create a design that uses a BGP multi-exit discriminator (MED) attribute to influence the egress path from Google Cloud to the on-premises environment.

B : Create a design that uses the as_path BGP attribute to influence the egress path from Google Cloud to the on-premises environment.

C : Create a design that uses an equal-cost multipath (ECMP) with flow-based hashing on your on-premises devices.

D : Create a design that uses the local_pref BGP attribute to influence the egress path from Google Cloud to the on-premises environment.

Answer: A
