Question 141

Your organization is implementing a new security policy to control how firewall rules are applied to control flows between virtual machines (VMs). Using Google-recommended practices, you need to set up a firewall rule to enforce strict control of traffic between VM A and VM B. You must ensure that communications flow only from VM A to VM B within the VPC, and no other communication paths are allowed. No other firewall rules exist in the VPC. Which firewall rule should you configure to allow only this communication path?

Firewall rule direction: ingressAction: allowTarget: VM B service accountSource ranges: VM A service accountPriority: 1000

Firewall rule direction: ingressAction: allowTarget: specific VM B tagSource ranges: VM A tag and VM A source IP addressPriority: 1000

Firewall rule direction: ingressAction: allowTarget: VM A service accountSource ranges: VM B service account and VM B source IP addressPriority: 100

Question 143

You are configuring a new HTTP application that will be exposed externally behind both IPv4 and IPv6virtual IP addresses, using ports 80, 8080, and 443. You will have backends in two regions: us-west1and us-east1. You want to serve the content with the lowest-possible latency while ensuring highavailability and autoscaling, and create native content-based rules using the HTTP hostname andrequest path. The IP addresses of the clients that connect to the load balancer need to be visible tothe backends. Which configuration should you use?

Use Network Load Balancing

Use TCP Proxy Load Balancing with PROXY protocol enabled

Use External HTTP(S) Load Balancing with URL Maps and custom headers

Use External HTTP(S) Load Balancing with URL Maps and an X-Forwarded-For header

Question 144

You need to define an address plan for a future new Google Kubernetes Engine (GKE) cluster in your Virtual Private Cloud (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?
