An administrator wants todisable password-based SSH accessfor thenutanix useron a CVMto improve security.
What action should the administrator take?
Correct Answer:
C
Enabling "Cluster Lockdown" in Nutanix is the best security measure to prevent password-based SSH logins.
✑ Option C (Enable Cluster Lockdown) is correct:
✑ Option A (Rename the nutanix user) is incorrect:
✑ Option B (Block port 22) is incorrect:
✑ Option D (Delete the nutanix user) is incorrect:

Refer to the Exhibit:
An administrator needs to create two virtual machines: VM4 and VM5 that leverage the memory over-commit feature.
Once VM4 is created and running, the administrator notices that it uses only 28GB of RAM. What will be the maximum RAM that can be allocated to VM5 so that it can be powered on?
Correct Answer:
B
Understanding the Exhibit & Memory Allocation
✑ Thehost has 128GB of physical RAM.
✑ Thecurrent memory allocationacrossthree VMs (VM1, VM2, VM3) is 128GB, but only92GB is actually utilized.
✑ This means there is36GB of unutilized memory available for allocation.
Step-by-Step Breakdown
✑ Existing Memory Usage Before Adding VM4
✑ After Creating and Running VM4
✑ Maximum Memory Allocation for VM5
Evaluating the Answer Choices
✑ (A) 4GB(Incorrect)
✑ (B) 8GB(Correct)
✑ (C) 16GB(Incorrect)
✑ (D) 32GB(Incorrect)
Key Concept: Nutanix Memory Overcommit
✑ Nutanix AHV supportsmemory overcommit, meaning VMs can be allocated more memory than physically available usingmemory ballooning and swapping.
✑ However,to power on VM5 without impacting performance, it must fit within the available unutilized memory, which is8GB.
An administrator needs tocreate a storage containerforVM disks. The container must meet the following conditions:
✑ 10 GiB of the total allocated space must not be used by other containers.
✑ The container must have a maximum storage capacity of 500 GiB.
What settings should the administrator configure while creating the storage container?
Correct Answer:
D
Nutanix storage containers allow administrators to configure capacity reservations and advertised limits for better resource management.
✑ Option D (Set Reserved Capacity to 10 GiB and Advertised Capacity to 500 GiB) is correct:
✑ Option A is incorrect:
✑ Option B is incorrect:
✑ Option C is incorrect:

Which update in LCM can an administrator apply on a per-node basis?
Correct Answer:
B
BMC (Baseboard Management Controller) updates can be applied per-node in Nutanix LCM, unlike AOS or AHV, which require cluster-wide upgrades.
✑ Option B (BMC) is correct:
✑ Option A (AOS) is incorrect:
✑ Option C (NCC) is incorrect:
✑ Option D (AHV) is incorrect:

An administrator has been tasked with performingfirmware upgradesfor all Nutanix sites.
When attempting to performfirmware upgrades via Life Cycle Manager (LCM)at a remote site with a single-node cluster, no firmware updates are listed as available. The administrator confirmed that the currently installed firmware isseveral revisions behind.
Why are no firmware upgrades listed in LCM for this cluster?
Correct Answer:
B
LCM (Life Cycle Manager) does not support automatic firmware upgrades for single- node clustersbecausefirmware updates require cluster-wide operations, which are not possible with only one node.
✑ Option B (LCM is not supported on single-node clusters) is correct:
✑ Option A (Single-node clusters only support one-disk firmware upgrades) is incorrect:
✑ Option C (LCM cannot perform firmware upgrades) is incorrect:
✑ Option D (LCM lacks internet connectivity) is incorrect:
