A newly-hired Nutanix administrator was tasked by the CIO to create a single VM on a test network. The network administrator stated that a native VLAN was used on the Cisco TOR switches with the following parameters:IP address:172,16.1.2Network Mask: 255.255.255.0Default gateway: 172.16.1.1VLAN:1The same parameters were used to create a network profile on Nutanix, but the when the VM was on ...What should the Nutanix administrator do to fix this issue?
Answer(s): B
A native VLAN is a VLAN that is assigned to untagged traffic on a trunk port of a switch. A trunk port can carry traffic from multiple VLANs, but it needs to have a native VLAN to handle traffic that does not have a VLAN tag. The native VLAN is usually VLAN 1 by default on most switches, but it can be changed to any other VLAN number2. When creating a network profile on Nutanix, the administrator needs to specify the VLAN ID that matches the VLAN configuration on the physical switch. However, if the network profile uses the same VLAN ID as the native VLAN on the switch, it will cause network connectivity issues for the VMs connected to that network profile. This is because Nutanix AHV uses 802.1Q tagging for all network traffic, including traffic in the native VLAN. The switch will expect untagged traffic in the native VLAN and will drop any tagged traffic in that VLAN3. To fix this issue, the administrator needs to change the VLAN field from vlan. 1 to vlan. 0 in the network profile on Nutanix. This will tell Nutanix AHV to send untagged traffic for that network profile and match the native VLAN configuration on the switch4.
An administrator needs to provide access for a user to view real-time performance metric for all VMs on all clusters across the datacenter.Which method accomplishes this with the least effort and ongoing maintenance?
Answer(s): C
The best method to provide access for a user to view real-time performance metrics for all VMs on all clusters across the datacenter is to configure AD authentication create a custom role, assign the user to the role, and apply the role to all clusters and VMs. This method accomplishes this with the least effort and ongoing maintenance because:AD authentication allows Nutanix Prism Central to integrate with an existing Active Directory (AD) domain and use AD users and groups for authentication and authorization5. This simplifies user management and avoids creating local users on Prism Central.Creating a custom role allows Nutanix Prism Central to define granular permissions for different actions and entities based on specific needs6. This ensures that users only have access to what they need and nothing more.Assigning the user to the custom role allows Nutanix Prism Central to grant access rights for that user based on the role definition7. This avoids assigning permissions individually for each user.Applying the role to all clusters and VMs allows Nutanix Prism Central to propagate the access rights for that role across all entities in scope8. This ensures that users can view real-time performance metrics for all VMs on all clusters without having to configure each entity separately.

When a configuring a syslog server in Prism Central, what two pieces information are required? (Choose two.)
Answer(s): C,D
According to the Nutanix Prism Central Guide, to configure a syslog server in Prism Central, you need to specify the transport protocol (TCP or UDP) and the IP address/port of the syslog server.
Upon logging into Prism Central, an administrator notices high cluster latency.How can the administrator analyze data with the least number of steps or actions?
According to the Nutanix Prism Central Guide, you can click on any chart in a widget to expand it and view more details about the data elements.
An administrator is tasked with configuring network on an AHV cluster and wants to maximize throughput for the host with many small VMs while minimizing network switch configuration.Which bond mode should the administrator select?
Answer(s): A
According to the Nutanix AHV Networking Guide, active-active bond mode provides load balancing and fault tolerance for network traffic by distributing packets across multiple interfaces using a hashing algorithm based on source and destination MAC addresses, IP addresses, and TCP/UDP ports. This mode does not require any special configuration on the network switch and can improve throughput for hosts with many small VMs.
