質問 # 25
A consultant needs to upgrade the ESXi hosts on a Nutanix cluster from version 6.7 to 7.0. vSphere DRS and wMoton are working properly. The consultant needs to use One-Click Upgrade.
Which setting should be verified by the consultant?

A. vSphere HA is enabled.
B. vSphere DRS Automation level is set to Conservative.
C. Nutanix Prism HA is enabled.
D. DRS automation level on all CVMs is disabled.

正解：A

解説：
When upgrading ESXi hosts on a Nutanix cluster using One-Click Upgrade, it is crucial to verify that vSphere HA (High Availability) is enabled. This setting ensures that in the event of host failure during the upgrade process, VMs will be automatically restarted on other hosts in the cluster, maintaining availability and minimizing disruption. Verifying this setting is essential to ensure the resilience of the environment during the upgrade.

質問 # 27
A consultant creates three storage containers (container-1, container-2, container-3). The customer requires that only container-1, which will be utilized as an NFS datastore, be presented to external hosts.
However, users are able to mount all three containers.
What is causing this problem?

A. A Global whitelist entry was configured.
B. A Container-level whitelist entry was configured.
C. Compression was turned on for all containers.
D. Deduplication was turned on for all containers.

正解：A

解説：
The issue where users can mount all three storage containers despite the intention to restrict access to just container-1 typically stems from a Global whitelist entry. A global whitelist allows all entities to access all containers unless more specific restrictions are applied at the container level. To correct this, specific whitelist entries need to be configured for each container to define and restrict access appropriately.References: Nutanix NCS-Core 6.8 training resources, the Nutanix Bible, and Nutanix technical documentation on storage container management.

質問 # 32
An administrator receives an alert in Prism indicating that interface eth2, on an AHV host is receiving many CRC errors. Aftertogging into the problematic host, the following command is run to show the indicated output:

What is causing this issue?

A. A misconfigured bond
B. A physical layer network problem
C. Incorrect link speeds on the switch
D. The interface is incorrectly configured with Jumbo Frames

正解：D

解説：
Explanation
Ref:
rx_crc_errors are caused either by faults in layer 1 (in the past, we have seen failed twinax cables and incorrect types of fibre being used), or issues with jumbo frames on the network. In an environment with
10Gig switches that use cut-through forwarding (Cisco Nexus, Arista, Cisco devices using IOS default to Store and Forward switching), any packets that come into the switch will get forwarded out the destination interface once the switch has read the destination MAC address. If that packet has an MTU over what is configured on the interface, it will cut off the packet at the designated MTU, causing the server to receive a malformed packet, which will throw a CRC error.
If you have a layer 1 issue, you will see not on all but one or two nodes.

質問 # 33
A customer racks all nodes in the new cluster. The customer does not allow IPv6 for node discovery.
The consultant is not allowed to use the consultant's own flat switch in the customer's environment.
Which step should the consultant take to resolve this issue?

A. Bare metal image all nodes with Foundation VM.
B. Connect to the top of rack switch and discover the nodes with IPv4.
C. Image each node individually with Foundation VM.
D. Open a console to all nodes and statically assign IP addresses.

正解：B

解説：
In environments where IPv6 is not allowed for node discovery and the use of an external flat switch by the consultant is also restricted, the viable approach is to connect to the top of rack switch and discover the nodes using IPv4. This method aligns with the customer's networking policies and leverages the existing network infrastructure to facilitate the discovery and configuration of the nodes within the Nutanix cluster.References:
Nutanix Bible, Nutanix University NCS-Core 6.8 resources, and Nutanix official guidelines on node discovery using IPv4.

* resources are critical for enabling the customer to independently deploy and manage Nutanix clusters under the unique constraints of a dark site.References: Nutanix Deployment Guide, Nutanix Support Portal Documentation.

質問 # 36
A consultant successfully completes a Foundation using a flat switch. The consultant then works with the customer to move the cluster over to their production network. After the move, the CVMs and hypervisors can no longer communicate, which prevents the cluster from starting.
Which option should be used to resolve this issue?

A. If the IPMI is in use, check that the IPMI can ping the default gateway over IPv6.
B. Verify that IPv6 Link Local and DHCP is enabled on all switch ports.
C. If using VLANs, confirm the hypervisor/CVM VLAN is set as Native on the switch ports.
D. Make sure that the IPMI and CVM VLAN is manually tagged on the Host and CVM.

正解：C

解説：
The inability of CVMs and hypervisors to communicate after moving a cluster to the production network typically points to a VLAN configuration issue. The correct action is to confirm that the VLAN designated for hypervisor/CVM communication is set as the Native VLAN on the switch ports to which the nodes are connected. This setting ensures that traffic from these VLANs is properly prioritized and handled by the network, thereby restoring communication between CVMs and hypervisors and allowing the cluster to start.References: Nutanix Bible, NCS-Core 6.8 official documentation on networking configurations, and troubleshooting VLAN issues.
