Question 56

You want to use Cloud Interconnect to connect your on-premises network to a GCP VPC. You cannot meet Google at one of its point-of-presence (POP) locations, and your on-premises router cannot run a Border Gateway Protocol (BGP) configuration. Which connectivity model should you use?

  1. Direct Peering
  2. Dedicated Interconnect
  3. Partner Interconnect with a layer 2 partner
  4. Partner Interconnect with a layer 3 partner

Question 57

You have configured a Compute Engine virtual machine instance as a NAT gateway. You execute the following command: gcloud compute routes create no-ip-internet-route \ --network custom-network1 \ --destination-range 0.0.0.0/0 \ --next-hop instance nat-gateway \ --next-hop instance-zone us-central1-a \ --tags no-ip --priority 800 You want existing instances to use the new NAT gateway. Which command should you execute?

  1. sudo sysctl -w net.ipv4.ip_forward=1
  2. gcloud compute instances add-tags [existing-instance] --tags no-ip
  3. gcloud builds submit --config=cloudbuild.waml --substitutions=TAG_NAME=no-ip
  4. gcloud compute instances create example-instance --network custom-network1 \ --subnet subnet-us-central \ --no-address \ --zone us-central1-a \ --image-family debian-9 \ --image-project debian-cloud \ --tags no-ip

Question 58

You need to configure a static route to an on-premises resource behind a Cloud VPN gateway that is configured for policy-based routing using the gcloud command. Which next hop should you choose?

  1. The default internet gateway
  2. The IP address of the Cloud VPN gateway
  3. The name and region of the Cloud VPN tunnel
  4. The IP address of the instance on the remote side of the VPN tunnel

Question 59

You need to enable Cloud CDN for all the objects inside a storage bucket. You want to ensure that all the object in the storage bucket can be served by the CDN. What should you do in the GCP Console?

  1. Create a new cloud storage bucket, and then enable Cloud CDN on it.
  2. Create a new TCP load balancer, select the storage bucket as a backend, and then enable Cloud CDN on the backend.
  3. Create a new SSL proxy load balancer, select the storage bucket as a backend, and then enable Cloud CDN on the backend.
  4. Create a new HTTP load balancer, select the storage bucket as a backend, enable Cloud CDN on the backend, and make sure each object inside the storage bucket is shared publicly.

Question 60

Your company's Google Cloud-deployed, streaming application supports multiple languages. The application development team has asked you how they should support splitting audio and video traffic to different backend Google Cloud storage buckets. They want to use URL maps and minimize operational overhead. They are currently using the following directory structure: /fr/video /en/video /es/video /../video /fr/audio /en/audio /es/audio /../audio Which solution should you recommend?

  1. Rearrange the directory structure, create a URL map and leverage a path rule such as /video/* and /audio/*.
  2. Rearrange the directory structure, create DNS hostname entries for video and audio and leverage a path rule such as /video/* and /audio/*.
  3. Leave the directory structure as-is, create a URL map and leverage a path rule such as \/[a-z]{2}\/video and \/[a-z]{2}\/audio.
  4. Leave the directory structure as-is, create a URL map and leverage a path rule such as /*/video and /*/audio.
