NCP-MCI-6.10 Exam Dumps - Nutanix NCM-MCI Questions and Answers

Active-Active bonding allows multiple network interfaces to be used simultaneously, improving bandwidth and redundancy.

Option B (Active-Active) is correct:

This mode enablesload balancing across all available adapters, providinghigher throughput and fault tolerance.

Option A (No Uplink Bond) is incorrect:

Without a bond, VMscannot benefit from multiple adapters.

Option C (Active-Active with MAC pinning) is incorrect:

MAC pinningbinds traffic to a single NIC, limiting bandwidth distribution.

Option D (Active-Backup) is incorrect:

This modeonly provides failover, not increased bandwidth.

Nutanix storage architecture uses distributed data paths, where each vDisk represents a distributed logical object. The performance best practices for databases state:

“Multiple vDisks provide parallelism across the Nutanix storage stack, increasing I/O queue depth and distributing operations across multiple CVMs.”

Also, the guidance for Linux-based database workloads specifies:

“Using LVM striping across multiple vDisks increases throughput by merging multiple I/O channels and enhancing parallel read/write operations.”

Thin vs thick provisioning is irrelevant for performance in a Nutanix environment, as both types deliver identical I/O performance due to the metadata-driven storage engine.

Thus, database performance benefits from additional vDisks and striping across them.

Nutanix Protection Policies replicate VM data between clusters using Nutanix’s built-in data protection engine. For inter-site or cloud-based replication, Nutanix documentation specifies that replication traffic can be encrypted using the Data-in-Transit Encryption feature. The internal description states:

“Data-in-Transit Encryption secures replication traffic moving between clusters by encrypting data packets before transmission across external or untrusted networks.”

This is distinct from Data-at-Rest Encryption, which protects stored data on disks but does not secure network traffic. Self-encrypting drives and secure boot only protect the VM locally, not the replication path. Because replication to NC2 travels over the Internet, encryption of the transport channel is mandatory to meet security compliance.

Therefore, the required capability is Data-in-Transit Encryption.

Nutanix AHV networking documentation describes IGMP Snooping as a feature that enables the AHV virtual switch to learn which VMs have joined specific multicast groups through IGMP membership reports. The documentation states that with IGMP Snooping enabled, multicast traffic is forwarded only to VMs that are registered members of a multicast group, preventing unnecessary flooding of multicast packets across all ports. LACP is for NIC bonding, network segmentation is for isolating networks, and LLDP is for link layer device discovery. None of these selectively deliver multicast traffic. Only IGMP Snooping provides the optimized multicast forwarding described.

In a 12-node FT2 cluster, onlyonenode can be placed into maintenance mode at a time. This ensures that the cluster maintains data redundancy and protection (FT2 indicates 2-failure tolerance).

From theNutanix Enterprise Cloud Administration (ECA)course materials:

“For FT2 clusters, a maximum of one node can be placed in maintenance mode at a time to ensure the cluster’s ability to tolerate failures and maintain quorum.”
