You are creating an instance group and need to create a new health check for HTTP(s) load balancing. Which two methods can you use to accomplish this? (Choose two.)
A.
Create a new health check using the gcloud command line tool.
B.
Create a new health check using the VPC Network section in the GCP Console.
C.
Create a new health check, or select an existing one, when you complete the load balancer's backend configuration in the GCP Console.
D.
Create a new legacy health check using the gcloud command line tool.
E.
Create a new legacy health check using the Health checks section in the GCP Console.
A and C.
Unless you use target pool-based Network LB, then it's required to use legacy health check, otherwise, legacy health check is not recommended to be used for HTTP(S) LB.

A and C for sure!

-Important lines from the link that lead me to say the answer is A and C:
''Google Cloud allows you to create or select a health check when you complete the load balancer's backend configuration in the Cloud Console." - A
"You can create a health check using the Cloud Console, the gcloud command-line tool, or the REST APIs." - C
Peace :)
Answer is AC. Most load balancers do not use legacy health checks, with exception of target pool-based Network load balancer requires legacy health checks. Definitely, you won’t find health check option in VPC network section

This one is tricky!
Answers are A&C...
Though you can create a legacy health check for HTTP(S) load balancing via gcloud tools -however it's ONLY for Target Pools, not instance groups. look here:
https://cloud.google.com/load-balancing/docs/health-check-concepts
And also - the question is not referring to an HTTP(S) Load BalancER...it's referring to HTTP(S) load BalancING.
Also when they are referring to 'new' health check - they imply to the NEW instance group. so selecting an existing HC is feasible since it's 'new' to the instance group... ;)
Thoughts?
Answer is A&C
Legacy health check is only applicable and required when you use target pool based NLB.
For almost all other load balancer types, you MUST use regular, non-legacy health checks where the protocol matches the load balancer's backend service protocol.

Answer is A,C as "Traffic Director and most load balancers use non-legacy health checks, but target pool-based Network Load Balancing requires that you use legacy health check". This question asks about https load balancer so definitely C makes a better choice than E.
Although the Cloud Console's health checks page lists and allows you to edit both health checks and legacy health checks, you cannot create a new legacy health check from the Cloud Console's health checks page.
AD
To create a legacy health check, use the Cloud Console's network load balancer page or use this section's gcloud or API instructions.
