Google Prof Cloud Network - pt 2

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.)

• Open a Cloud Support ticket under the Cloud Interconnect category.

• Download the LOA-CFA from the Hybrid Connectivity section of the GCP Console.

• Run gcloud compute interconnects describe .

• Check the email for the account of the NOC contact that you specified during the ordering process.

• Contact your cross-connect provider and inform them that Google automatically sent the LOA/CFA to them via email, and to complete the connection.

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?

• Create a Cloud Armor Policy rule that denies traffic and review necessary logs.

• Create a Cloud Armor Policy rule that denies traffic, enable preview mode, and review necessary logs.

• Create a VPC Firewall rule that denies traffic, enable logging and set enforcement to disabled, and review necessary logs.

• Create a VPC Firewall rule that denies traffic, enable logging and set enforcement to enabled, and review necessary logs.

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 liftand-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?

• Create a managed instance group from one of the images of the on-premises servers, and link this instance group to a target pool behind your load balancer.

• Create a target pool, add all backend instances to this target pool, and deploy the target pool behind your load balancer.

• Deploy a third-party virtual appliance as frontend to these servers that will accommodate the significant differences between these backend servers.

• Use GCP's ECMP capability to load-balance traffic to the backend servers by installing multiple equalpriority static routes to the backend servers.

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?

• The instance has been configured with multiple interfaces.

• An external IP address has been configured on the instance.

• An external IP address has been configured on the instance.

• The instance is accessible by a load balancer external IP address.

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?

• AS-Path

• Community

• Local Preference

• Multi-exit Discriminator

You are increasing your usage of Cloud VPN between on-premises and GCP, and you want to support more traffic than a single tunnel can handle. You want to increase the available bandwidth using Cloud VPN. What should you do?

• Double the MTU on your on-premises VPN gateway from 1460 bytes to 2920 bytes.

• Create two VPN tunnels on the same Cloud VPN gateway that point to the same destination VPN gateway IP address.

• Add a second on-premises VPN gateway with a different public IP address. Create a second tunnel on the existing Cloud VPN gateway that forwards the same IP range, but points at the new on-premises gateway IP.

• Add a second Cloud VPN gateway in a different region than the existing VPN gateway. Create a new tunnel on the second Cloud VPN gateway that forwards the same IP range, but points to the existing on-premises VPN gateway IP address.

You are disabling DNSSEC for one of your Cloud DNS-managed zones. You removed the DS records from your zone file, waited for them to expire from the cache, and disabled DNSSEC for the zone. You receive reports that DNSSEC validating resolves are unable to resolve names in your zone. What should you do?

• Update the TTL for the zone.

• Set the zone to the TRANSFER state.

• Disable DNSSEC at your domain registrar.

• Disable DNSSEC at your domain registrar.

What is the most likely cause of the missing log lines?

• The traffic is matching the expected ingress rule.

• The traffic is matching the expected egress rule.

• The traffic is not matching the expected ingress rule.

• The traffic is not matching the expected egress rule.

You have configured Cloud CDN using HTTP(S) load balancing as the origin for cacheable content. Compression is configured on the web servers, but responses served by Cloud CDN are not compressed. What is the most likely cause of the problem?

• You have not configured compression in Cloud CDN.

• You have configured the web servers and Cloud CDN with different compression types.

• The web servers behind the load balancer are configured with different compression types

• You have to configure the web servers to compress responses even if the request has a Via header.

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?

• Configure a policy-based route rule to prioritize the traffic.

• Configure an HTTP load balancer, and direct the traffic to it.

• Configure Dynamic Routing for the subnet hosting the application.

• Configure the TTL for the DNS zone to decrease the time between updates.
