Practice Test 4 | Google Cloud Certified Professional Cloud Architect | Dumps | Mock Test
You have been asked to migrate to the Cloud, a legacy system, listening to specific TCP ports, in a “lift and shift way”, that needs different types of instances but is accessed by a single IP address.
Which configuration among the following would you evaluate as the best one?
A. Layer 7 Load Balancer with an Unmanaged Instance Group
B. Layer 4 Load Balancer with a Managed Instance Group
C. Layer 4 Load Balancer with an Unmanaged Instance Group
D. Layer 7 Load Balancer with a Managed Instance Group
Correct Answer: C
A is wrong. The application does not use HTTP(s), so an HTTP(S) Load Balancer is out of scope
B is wrong. Managed Instance Groups are for scalable and identical Instances
C is correct. It is the only feasible way
D is wrong. The application does not use Http, and Managed Instance Groups is for scalable and identical Instances
