Practice Test 2 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test
You need to create a load balancer with a Cloud Storage bucket as the backend to serve an application within a VPC network. Which of the following options is the preferred approach?
A. Create an internal HTTPS load balancer and a serverless NEG as the backend
B. Create an internal TCP/UDP load balancer and a serverless NEG as the backend
C. Create an regional external TCP/UDP load balancer and a private Google access NEG as the backend
D. Create an internal HTTPS load balancer and a Private Service Connect NEG as the backend
E. Create an internal TCP/UDP load balancer and a Private Service Connect NEG as the backend
Correct Answer: D
Google Cloud load balancer support the following backends (see reference[1]):
- Instance group
- Zonal NEG
- Serverless NEG
- Internet NEG
- Hybrid connectivity NEG
- Private Service Connect NEG
There is no private Google access NEG. See reference[3].
A serverless NEG can represent one of the following, but not Cloud storage bucket (see reference[2]):
- A Cloud Run service or a group of services.
- A Cloud Functions function or a group of functions.
- An App Engine app (Standard or Flex), a specific service within an app, a specific version of an app, or a group of services.
- Option A is incorrect as serverless NEG doesn’t support Cloud storage bucket. See reference[2].
- Option B is incorrect as serverless NEG doesn’t support Cloud storage bucket. Also a HTTPS load balancer should be used here.
- Option C is incorrect as there is no private Google access NEG. See reference[3].
- Option D is CORRECT as Google Cloud load balancer supports Private Service Connect NEG, you can create private endpoints using global internal IP addresses within your VPC network. This option gives you access to all Google APIs and services that are included in the API bundles. You can also restrict access to only certain APIs and services. See reference[4].
- Option E is incorrect as a HTTPS load balancer should be used here.
