NEW QUESTION # 29
A consultant has finished imaging all assigned clusters and is ready to close out the engagement Which action is part of the Closeout Checklist?
- A. Provide an overview of Nutanix Prism Central.
- B. Provide an overview of Nutanix NDB.
- C. Provide an overview of Nutanix Self-Service.
- D. Provide an overview of Nutanix NC2.
Answer: A
Explanation:
During the closeout of a cluster imaging engagement, a key action to include in the Closeout Checklist is:
* Provide an overview of Nutanix Prism Central: This is crucial as Prism Central is the management and operations platform for Nutanix environments, providing visibility and control over clusters and workloads. Giving an overview of this tool is essential for the customer to manage their newly imaged clusters effectively.

NEW QUESTION # 30
A customer needs a 20-node cluster built. The consultant only has a 16-port flat network switch, and the customer is using VLAN tagging for the hosts and CVMs.
How should the consultant create the cluster?
- A. Create the Nutanix cluster manually.
- B. Connect the cluster to the production network.
- C. Set VLAN tags on all hosts and CVMs.
- D. Create a separate four-node cluster.
Answer: A
Explanation:
Given the constraint of a 16-port switch for a 20-node cluster, the consultant cannot physically connect all nodes to the network simultaneously. VLAN tagging allows multiple virtual networks to be carried over the same physical network. However, the challenge here is not about VLANs but the physical limitation of ports.
The practical approach would be to manually create the cluster, potentially in stages, as the full network capacity required for all nodes is not available.References:

NEW QUESTION # 31
An administrator is currently using both 10g uplink with LACP and balance-tcp. A single VM should not be allowed to use more than a single 10G uplink, and both uplinks should be utilized.
Which two command should be used to configure the bond? (choose two)
- A. Ovs-vsctl set port br0-up bond_mode=active-backup
- B. Ovs-vsctl set port br0-up other_config: bond-rebalance-interval=30000
- C. Ovs-vsctl set port br0-up bond_mode=balance-slb
- D. Ovs-vsctl set port br0-up bond_mode=balance-tcp
Answer: B,C
Explanation:
For a configuration where a single VM should not exceed the bandwidth of a single 10G uplink and both uplinks need to be utilized, the correct bonding mode is balance-slb (Source Load Balancing). This mode allows both uplinks to be utilized while ensuring that a single VM will not exceed the capacity of one uplink, as traffic from each VM or "source" is assigned to one of the links in the bond. The other_config:
bond-rebalance-interval=30000 command is used to set the interval at which the bonding driver will rebalance the assignment of sources to links in the bond. This helps in maintaining optimal distribution of load across the links as network conditions change.

NEW QUESTION # 33
An administrator is planning to deploy a Nutanix cluster to support a few high-performance VMs. This deployment will have the followingconsiderations:
* Individual VMs will likely generate network throughputs in the range of 90-100Mbps
* Due to the configuration of the VMs, it is unlikely that a node will host more than one or two of them at a time
* Individual VMs will communicatewith only a few (one or two) remote hosts at a time
* Multicast will not be used in the environment
* The hosts are connected via two 1GbE network connections
How should the administrator configure the network bonds to meet this requirement while maintaining the simplest switch configuration?
- A. Configure bond0 as balance-tcp
- B. Configure bond0 as balance-sib
- C. Configure bond0 as active-backup
- D. Configure bond0 as balance-lacp

NEW QUESTION # 34
A consultant successfully installs the Foundation VM on a laptop and needs to ensure the VM can communicate externally.
Which two configuration changes should the consultant make next? (Choose two.)
- A. Run the set_foundation_ip_address application on the VM desktop.
- B. Open terminal and configure via ifconfig command.
- C. Ensure the vNIC is set to bridged adapter.
- D. Configure the static IP address through the desktop virtualization software.
Answer: A,C
Explanation:
To ensure that the Foundation VM can communicate externally, the virtual network interface card (vNIC) should be set to a bridged adapter. This setting allows the VM to appear as a unique entity on the network, receiving its own IP address accessible from outside the host machine. Additionally, running the
'set_foundation_ip_address' application on the VM desktop enables the consultant to configure a specific, reachable IP address for the Foundation VM, ensuring it can communicate effectively with external network resources and devices.

Which two configuration changes should the consultant make next? (Choose two.)
- A. Run the set_foundation_ip_address application on the VM desktop.
- B. Open terminal and configure via ifconfig command.

NEW QUESTION # 38
A consultant creates a new cluster using ESXi as the hypervisor. After creating the cluster, the consultant begins to run Life Cycle Manager (LCM) updates. During the LCM upgrade pre-checks, an error is returned.
Which configuration is causing this issue?
- A. ESXi cluster HA is enabled.
- B. ESXi cluster admission control is disabled.
- C. ESXi cluster admission control is enabled.
- D. ESXi cluster DRS is enabled.
Answer: C
Explanation:
The error during LCM pre-checks in an ESXi-based Nutanix cluster with HA enabled is most likely due to the ESXi cluster admission control being enabled. Admission control is a feature in VMware ESXi that reserves resources for HA purposes to ensure that sufficient resources are available in the event of host failures. When admission control is enabled, it can interfere with Nutanix LCM operations, which may require resource reallocation or reconfiguration that conflicts with the reserved capacities set by admission control. Disabling admission control during LCM updates would typically resolve this issue.References: VMware documentation on HA and Admission Control, Nutanix LCM documentation.
NEW QUESTION # 39
An administrator needs to maximize storage potential in a six-node cluster. The container is configured with the following:
* Post-process compression
* Capacity deduplication
What should the administrator configure to increase space savings?
- A. Cache dedupe
- B. Reserve capacity
- C. Erasure coding
- D. Inline compression
Answer: C
Explanation:
The administrator's goal is to maximize storage potential in a cluster already configured with post-process compression and capacity deduplication. Erasure Coding (EC-X) is an effective method to further increase space savings by reducing the amount of redundancy data required for fault tolerance. It splits data into multiple chunks, which are distributed across the cluster, and parity is calculated and stored. This method is more space-efficient compared to traditional RAID or mirroring techniques, especially in environments where large data volumes need efficient storage.

* Use of redundant ToR switches
* Fastest reconvergence during link failure
How should the load balancing be configured on the host?
