You need to define an address plan for a future new GKE cluster in your VPC. This will be a VPC native cluster, and the default Pod IP range allocation will be used. You must pre-provision all the needed VPC subnets and their respective IP address ranges before cluster creation. The cluster will initially have a single node, but it will be scaled to a maximum of three nodes if necessary. You want to allocate the minimum number of Pod IP addresses.
Which subnet mask should you use for the Pod IP address range?

• A./21
• B./22
• C./23
• D./25

You want to implement an IPSec tunnel between your on-premises network and a VPC via Cloud VPN. You need to restrict reachability over the tunnel to specific local subnets, and you do not have a device capable of speaking Border Gateway Protocol (BGP).
Which routing option should you choose?

• B.Policy-based routing using the default local traffic selector
• C.Dynamic routing using Cloud Router
• D.Route-based routing using default traffic selectors

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?

• A.sudo sysctl -w net.ipv4.ip_forward=1
• B.gcloud compute instances add-tags [existing-instance] --tags no-ip
• C.gcloud builds submit --config=cloudbuild.waml --substitutions=TAG_NAME=no-ip
• D.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

What should you first?

• B.Ask your Interconnect partner to provision a physical connection to Google.
• C.Create a Partner Interconnect type VLAN attachment in the GCP Console and retrieve the pairing key.
• D.Run gcloud compute interconnect attachments partner update <attachment> / -- region <region> --admin-enabled.
