Practice Test 2 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test
An organisation wants to migrate its external-facing applications running on VMs in their data centre to GCP. Its users are all in Northern Virginia (us-east4), and the following requirements have been provided to you as the Network Engineer:
a. Applications will be deployed to private GCE instances with load balancing for high availability and scalability
b. Preservation of source IP addresses must be supported.
c. SSL will be decrypted by the backend service
Which of the following solutions is most suitable for this?
A. Internal HTTP(S) load balancer with a backend service of managed instance groups in different regions.
B. SSL Proxy load balancer with managed instance groups in the specified region
C. External HTTP(S) load balancer with a managed instance groups in different regions.
D. Network load balancer with a backend service of managed instance groups in the specified region
Answer: D
Option A is incorrect because the Internal HTTP(S) load balancer is not external facing and it is regional.
Option B is incorrect because it does not preserve source IP and it has SSL offload even though it is a global load balancer.
Option C is incorrect because it does not preserve source IP and it has SSL offload even though it is a global load balancer
Option D is correct because it meets all the specified requirements and it is a regional load balancer.
