You have deployed an HTTP(s) load balancer, but health checks to port 80 on the Compute Engine virtual machine instance are failing, and no traffic is sent to your instances. You want to resolve the problem. Which commands should you run?
A.
gcloud compute instances add-access-config instance-1
• C. gcloud compute firewall-rules create allow-lb --network load-balancer --allow tcp --source-ranges 130.211.0.0/22,35.191.0.0/16 --direction INGRESS *****
The following example creates an ingress firewall rule for the following load balancers:
• Internal TCP/UDP load balancer
• Internal HTTP(S) load balancer
• External TCP proxy load balancer
• Internal regional TCP proxy load balancer
• External SSL proxy load balancer
• Global external HTTP(S) load balancer
• Regional external HTTP(S) load balancer
For these load balancers, the source IP ranges for health checks (including legacy health checks if used for HTTP(S) Load Balancing) are:
Yes, C is right.
C. gcloud compute firewall-rules create allow-lb --network load-balancer --allow tcp --source-ranges 130.211.0.0/22,35.191.0.0/16 --direction INGRESS
