AHV IPAM assigns an IP address from the address pool when creating a managed VM NIC.
At which two instances does the address release back to the pool? (Choose two)

Administrators can use Acropolis with IPAM to deliver a complete virtualization deployment, including network management, from the unified Prism interface. This capability radically simplifies the traditionally complex network management associated with provisioning VMs and assigning network addresses. To avoid address overlap, be sure to work with your network team to reserve a range of addresses for VMs before enabling the IPAM feature.
The Acropolis master assigns an IP address from the address pool when creating a managed VM NIC; the address releases back to the pool when the VM NIC or VM is deleted.
An administrator manages an AHV cluster that is dedicated to a dev/test environment. The administrator receiving complaints from users that they are unable to create new VMs on the cluster.
After the reviewing the cluster, the administrator finds that the memory resources are almost fully utilized, with many VMs over-provisioned on memory.
What option is the most efficient resolution to enable additional VMs to be created?
After deploying a cluster, time is not synchronizing properly.
What task needs to be performed?
The task that needs to be performed when time is not synchronizing properly after deploying a cluster is NTP configuration. In the Nutanix Multicloud Infrastructure (NCP-MCI) 6.5, Network Time Protocol (NTP) is used to synchronize the system time across all the nodes in a cluster. If the time is not synchronizing properly, it indicates that there might be an issue with the NTP configuration. Therefore, checking and correcting the NTP configuration would be the appropriate action to resolve this issue. The other options like DNS configuration, HA configuration, and SMTP configuration are not directly related to time synchronization in a cluster.
Refer to the Exhibit:
An administrator is adding a new node to a cluster. The node has been imaged to the same versions of AHV and AOS that the cluster is
running, configured with appropriate IP addresses, and br0-up has been configured in the same manner as the existing uplink bonds.
When attempting to add the node to the cluster with the Expand Cluster function in Prism, the cluster is unable to find the new node.
Based on the above output from the new node, what is most likely the cause of this issue?
The output in the exhibit indicates that the node's network interfaces (eth0-eth3) are bonded together using LACP (Link Aggregation Control Protocol) with 'balance-tcp' as the bonding mode and LACP speed set to 'fast'. For LACP to function correctly, the switch ports to which the node is connected must also be configured to support LACP. If the ports on the upstream switch are not configured for LACP, the bond will not be able to establish properly, and the node will not communicate effectively on the network, making it undiscoverable when attempting to expand the cluster.
The absence of an operational LACP configuration could prevent the new node from joining the existing cluster as the node's network interfaces would not be able to pass traffic correctly. This can be verified by checking the switch configuration to ensure that the ports are set to participate in an LACP bond.
The other options, such as a firewall blocking discovery traffic (Option A) or the node being on different VLANs (Option C), are possible causes for a node not being discovered, but given the specific command output provided, the most likely cause is related to the switch port configuration for LACP. Option D, regarding completing LACP configuration after cluster expansion, is not correct because LACP needs to be operational for the node to communicate with the cluster during the expansion process.
Proper LACP configuration is critical for network communication in a Nutanix AHV cluster, and this is covered in detail in the Nutanix AHV and Networking documentation. It outlines the steps for configuring network bonds and LACP on both the AHV hosts and the connecting network infrastructure.
On a Nutanix cluster, what does Network Segmentation refer to?
network segmentation on Nutanix clusters refers to creating a separate network for service-specific communication and isolating different types of traffic over selected VLANs or physical interfaces.
