Practice Test 1 | Google Cloud Certified Associate Cloud Engineer | Dumps | Mock Test
You have recently joined a startup that is migrating its infrastructure from AWS to Google Cloud. A junior has been assigned the task of migrating one of their web servers with Amazon Linux OS from AWS to GCP in a public subnet of custom VPC. He is able to migrate the instance successfully, but not able to get SSH access of migrated instance. What are the possible steps to look for? (Multiple Answer)
A. Check if he has attached correct firewall rule with port udp:22 open to the instance.
B. Check if he has added SSH key to the instance while launching phase.
C. Google Cloud does not support Amazon Linux images because of market competition.
D. Make sure the firewall is attached to the instance with tcp port 22 open.
Explanation:
Correct Answer – B and D
B and D are correct: SSH works on TCP port 22 and hence that has to be allowed at firewall level along with public SSH key configured on VM. Hence, correct answers are B and D.
