NCP-MCI-6.5 Practice Test

Explanation: When a VM is connected to a Nutanix managed network, the IP address is assigned when the VM is powered on. A Nutanix managed network is a network that is created and managed by Prism Central using IP address management (IPAM). IPAM allows Prism Central to automatically assign IP addresses to VMs from a pool of available addresses in a subnet. IPAM also tracks the IP address usage and availability across clusters and networks4.
When a VM is connected to a Nutanix managed network, the administrator can choose one of the following assignment types for the IP address:
Assign Static IP: This option allows the administrator to manually specify a static IP address for the VM from the subnet range. The IP address will not change unless the administrator changes it.
Assign with DHCP: This option allows Prism Central to dynamically assign an IP address for the VM from the subnet range using DHCP. The IP address may change depending on the DHCP lease time and availability.
No Private IP: This option allows the administrator to skip assigning an IP address for the VM. This option is useful for scenarios where the administrator wants to use an external IPAM solution or assign an IP address later5.
Regardless of the assignment type, the IP address is assigned when the VM is powered on. This is because Prism Central needs to communicate with the hypervisor (AHV or ESXi) to configure the virtual NIC (vNIC) of the VM with the IP address information. This communication can only happen when the VM is in a powered on state6.

Explanation:
The correct answer is D. VM Storage Controller Bandwidth.

VM Storage Controller Bandwidth is a metric that measures the amount of data that a VM is reading and writing to the storage fabric. The storage fabric is the network of storage controllers (CVMs) that provide distributed and fault-tolerant storage services to the VMs on the Nutanix cluster. The VM Storage Controller Bandwidth metric shows the read and write bandwidth in megabytes per second (MBps) for each VM. The higher the bandwidth, the more data the VM is transferring to and from the storage fabric1.

The administrator can use Prism Central to view the VM Storage Controller Bandwidth metric for each VM in a chart or a widget. The administrator can also use Prism Central to view other metrics related to the VM’s storage performance, such as VM Storage Controller IOPS, VM Storage Controller Latency, and VM Disk Usage2.

Explanation: The issue described pertains to the inability to ping the IPMI IPs after moving the IPMI network links to the actual switches with specific VLAN configurations. The two changes that the administrator needs to make are:

A. SSH to AHV and set the VLAN ID using IPMI Tool: Since all VLANs are tagged in the new network configuration, the IPMI network interface needs to be aware of the VLAN it’s supposed to communicate on. This can be achieved by setting the VLAN ID using the IPMI Tool on the AHV.

C. SSH to AHV and change the IP address using IPMI tool: If the IPMI IP addresses were initially set in a different subnet that is not routable in the new network configuration, the administrator would need to change the IPMI IP addresses to match the new network configuration. This can be done by SSHing to the AHV and using the IPMI Tool to change the IP address.

Explanation: The change password at next logon attribute is a setting that forces a user to change their password when they log on to a domain for the first time or after their password has expired. This attribute is enabled by default for new Active Directory user accounts or when an administrator resets a user’s password4.
However, Prism Central does not support this attribute for Active Directory authentication. Users with this attribute enabled will not be able to log on to Prism Central using their Active Directory credentials. They will receive an error message saying “Invalid credentials” or “Authentication failed” when they try to log on5.
Therefore, if an administrator is not able to log on to Prism Central using a new Active Directory user account, the most likely cause of this issue is that the change password at next logon attribute is set for that user account. To resolve this issue, the administrator should disable this attribute for the user account or log on to a domain workstation first and change their password before accessing Prism Central6.
