Actual exam question for Nutanix's NCM-MCI exam

Question #: 1
Topic #: 1

Task 16

Running NCC on a cluster prior to an upgrade results in the following output

FAIL: CVM System Partition /home usage at 93% (greater than threshold, 90%)

Identify the CVM with the issue, remove the fil causing the storage bloat, and check the health again by running the individual disk usage health check only on the problematic CVM do not run NCC health check

Note: Make sure only the individual health check is executed from the affected node

Suggested Answer: A

To identify the CVM with the issue, remove the file causing the storage bloat, and check the health again, you can follow these steps:

Select Virtual Machines from the drop-down menu and find the NCC health check output file from the list. You can use the date and time information to locate the file. The file name should be something like ncc-output-YYYY-MM-DD-HH-MM-SS.log.

Open the file and look for the line that says FAIL: CVM System Partition /home usage at 93% (greater than threshold, 90%). Note down the IP address of the CVM that has this issue. It should be something like X.X.X.X.

Run the commanddu -sh /home/*to see the disk usage of each file and directory under /home. Identify the file that is taking up most of the space. It could be a log file, a backup file, or a temporary file. Make sure it is not a system file or a configuration file that is needed by the CVM.

Run the commandrm -f /home/<filename>to remove the file causing the storage bloat. Replace <filename> with the actual name of the file.

Run the commandncc health_checks hardware_checks disk_checks disk_usage_check --cvm_list=X.X.X.Xto check the health again by running the individual disk usage health check only on the problematic CVM. Replace X.X.X.X with the IP address of the CVM that you noted down earlier.

Verify that the output shows PASS: CVM System Partition /home usage at XX% (less than threshold, 90%). This means that the issue has been resolved.

Not sure if just removing files will solve the issue long-term.

I think I recall that we should look for large files in the /home directory, but I’m not clear on the exact commands to use for checking disk usage.

I’m a bit confused about running only the individual health check. Do we need to specify the CVM name when we execute that command?

This seems similar to a practice question we did on disk usage thresholds. I think we need to check the logs to find the specific file.

I remember we practiced identifying the CVM with high usage, but I’m not entirely sure how to remove the file causing the bloat.

This seems straightforward enough. I just need to follow the steps - find the CVM, remove the file, and run the individual check. As long as I don't mess up the last part, I should be able to handle this.

Alright, let's see. First I'll need to identify the CVM with the issue, then remove the file causing the storage bloat, and finally run the individual disk usage check. Gotta be careful not to run the full NCC health check.

Whoa, 93% usage on the /home partition? That's definitely a problem. I'll need to dig in and figure out what's taking up all that space.

Okay, the key things I need to focus on are finding the CVM with the high storage usage, removing the file causing the bloat, and then running the individual disk usage check. I'll need to be thorough but efficient.

Okay, let me think this through step-by-step. The question is asking about the default state for VMs that are not encrypted, so I need to remember what the options are and which one is the default.

Okay, I remember learning that zero-based budgeting is more time-consuming than other approaches, so option C is definitely not correct. I'll eliminate that one.

Okay, I've got a strategy here. The question is asking about the requirement to enable the feature of having an admin node available at all times. So I need to focus on the admin node aspect, not the other node types. I'm leaning towards A as the best option.

Okay, so the key steps are: 1) identify the CVM, 2) remove the file causing the bloat, and 3) check the health of just that CVM. Sounds straightforward enough.

I wonder what kind of file could be causing such a huge storage issue? Maybe someone downloaded a bunch of cat videos or something. *chuckles*

Hmm, this seems like a tricky one. Running NCC and finding the CVM system partition at 93% usage is definitely a problem that needs to be addressed before an upgrade.
