S2 — Describe Nutanix Platform Administration 23 cards
2.1
Most efficient way to apply one policy to dozens of VMs?
Tag the VMs with a category, then associate the category with the policy.
2.1
How do you keep a per-host appliance VM (e.g. a firewall) on its host?
Mark it as an Agent VM.
2.1
How do you keep two SQL VMs on different AHV hosts?
Create a VM-VM anti-affinity group with aCLI.
2.1
What does Flash Mode do?
It pins a VM's or vDisk's data to the SSD tier.
2.1
How can you add an image from a remote location to the Image Service?
By URL over HTTP (or by uploading a file from your workstation).
2.1
What maps images to target clusters?
Image Placement Policies use categories.
2.1
Restoring a critical VM in place from Prism Central uses which object?
A recovery point (revert / restore in place).
2.1
Can you hot-remove memory from a running AHV VM?
No. You can hot-add memory and vCPUs but not remove them.
2.2
Default AHV bond mode?
Active-Backup: one link is active and the rest stand by. No switch configuration is needed.
2.2
Which bond mode hashes on IP addresses and TCP/UDP ports?
Active-Active with LACP (balance-tcp).
2.2
What is AHV's virtual switching built on?
Open vSwitch (OVS): virtual switch vs0, bridge br0, and an uplink bond.
2.2
Which subnet type assigns IPs to VMs automatically?
A virtual network with IPAM enabled.
2.2
How do you separate management from storage-replication traffic?
Network segmentation.
2.2
What does the Network Visualizer show?
Hosts, uplinks, VMs and the physical switch ports they connect to (via LLDP/CDP/SNMP).
2.3
Where are RF and storage-efficiency policies applied?
On the storage container.
2.3
What does RF2 mean?
Two copies of every piece of data are written to different nodes.
2.3
Which efficiency feature suits nearly every workload?
Compression.
2.3
Which efficiency feature replaces RF copies with parity for cold data?
Erasure coding (EC-X).
2.3
Where does deduplication pay off most?
Where VMs share identical blocks, such as full clones and VDI.
2.3
What is stored as files on CVM-owned disks?
Extent groups.
2.3
What should you check before configuring RF1?
Its prerequisites (including the node count). RF1 is only for disposable or scratch data.
2.4
What must you do before destroying a licensed cluster?
Reclaim its licenses.
2.4
Seamless vs manual licensing?
Seamless means connected one-click actions in Prism Central. Manual means uploading a cluster summary file and applying a license file (dark sites).
