Exam Professional Cloud Architect topic 2 question 2 discussion

Assumption:- VM in production environment, cannot be taken down. based on above, A/B are out. E causes downtime to remove the VM from the old network and connect it to a new network for testing. Only leaves CDF C - Snapshotting is fine, it will reduce the performance for a short duration, but the database will still be up D - Obvious place to check for firewall rules (if ssh ports are open or not) F - Easy to see server messages on console (without downtime)

CDF best answers

D and F are ok and easy to conclude on. Between E and C - C may cause disruptions to a running production VM. E allows us to snapshot to a different VM and you can check the sshd configuration there. Also connect the snapshotted VM to the same networks to troubleshoot in real time

CDF is correct. Dcoumentation with regards to option C : https://cloud.google.com/compute/docs/troubleshooting/troubleshooting-ssh#inspect_vm

go with DEF. C doesn't make sense, taking a snapshot for OS and connect to new machine, it won't tell you what's going on with ssh session.

vote CDF

Answer is CDF

C. Take a snapshot of the disk and connect to a new machine to investigate D. Check inbound firewall rules for the network the machine is connected to F. Print the Serial Console output for the instance for troubleshooting, activate the interactive console, and investigate

Answer are C,D, F

I will vote for CEF

You need to select 1 from A/B/C before you can have something to troubleshoot. You cannot troubleshoot on a running PORD server. C is best. D/E/F get 2, rule out E.

C. SSH is related to the VM, not to the database. Why would you create a snapshot of the disk and attach it to a NEW VMs? by creating a new VM you could fix the SSH problem without even attaching the disk. D. Doesnt make sense to print the output, but it does make sense to log into the console and troubleshoot SSH. I'll go with DEF.

CDF is ok

I think DEF.. need to Snapshot? why?

Agree with CDF

I like DEF - the problem with C is you are snapshotting an instance which is currently being queried by the application, you are definitely going to cause an IOPS spike..
