NCA-6.10 Exam Dumps - Nutanix Certified Associate (NCA) Questions and Answers

When configuring dual encryption in Nutanix, anExternal Key Manager(EKM) is required. This allows the cluster to use an external hardware-based or software-based key management system to securely store and manage encryption keys. The combination of external and native encryption ensures compliance with high security standards.

A. Trusted Platform Module:Incorrect, as TPM is not used for managing dual encryption keys.

B. External Key Manager:Correct, as dual encryption relies on an external system to manage keys.

C. Native Key Manager:Incorrect, as native key management alone does not support dual encryption.

D. Lockdown Mode Enabled:Incorrect, as Lockdown Mode relates to cluster security, not encryption key management.

In Prism Central, theImagessection within the Compute and Storage tab is used to upload ISO files, including Windows installation ISOs. Once uploaded, these images can be used to create or install VMs across clusters managed by Prism Central.

A. Catalog Items:Incorrect, as this is used to manage preconfigured application templates.

B. Templates:Incorrect, as this is used for VM templates, not ISO uploads.

C. Images:Correct, as it allows uploading and managing ISO and disk images.

D. OVAs:Incorrect, as this pertains to importing virtual appliances, not ISO files.

When a Nutanix cluster alert occurs, indicating maintenance mode issues, the most likely cause is that another node in the cluster is already in maintenance mode. Nutanix clusters enforce restrictions to prevent more than one node from entering maintenance mode simultaneously. This ensures the cluster can maintain resiliency and availability, adhering to the redundancy factor (RF) policy.

If another node is already in maintenance mode, the cluster cannot afford to have additional nodes enter maintenance without compromising data and service availability.

In aRedundancy Factor 3 (RF3)cluster,5 copies of the metadataare maintained to ensure data durability and cluster resiliency. RF3 provides fault tolerance against up to two simultaneous failures (e.g., node or disk failures) and requires more metadata copies to achieve this level of protection.

Other redundancy factors:

RF2maintains 3 copies of metadata.

RF3 requires at least 5 metadata copies to protect against additional failures.

The feature that ensures VMs automatically power on in a specific order at the DR site during a disaster is aRecovery Plan. Recovery Plans are part of Nutanix’s DR functionality and allow administrators to define startup sequences, dependencies, and priorities for VMs during failover scenarios.

Steps:

Create a Recovery Plan in Prism Central under the DR section.

Configure the VM power-on sequence and dependency rules.

Test the Recovery Plan to ensure it operates as intended.

Shared storage for Windows Server Failover Clustering (WSFC) is a use case for NutanixVolumes. Nutanix Volumes provides block storage (via iSCSI) to external systems, such asWSFC nodes, allowing them to share storage for failover clustering. This configuration is essential for high availability in Windows environments.

Other options:

Files: Provides file-based storage (NFS/SMB), not suited for WSFC shared block storage.

FT1 and RF2: Refer to Fault Tolerance and Redundancy Factor, not storage solutions.

When configuring a physical network switch in Prism Element,SNMP Configurationis required to enable monitoring and communication between the Nutanix cluster and the network switch. SNMP (Simple Network Management Protocol) is used to gather metrics and detect issues such as link failures or performance bottlenecks, ensuring the cluster operates efficiently with the physical network infrastructure.

To prevent password access to the CVM for both thenutanixandadminuser accounts,Cluster Lockdownshould be enabled. Cluster Lockdown restricts SSH access to the Controller VM (CVM), effectively disabling password-based logins for enhanced security. Access is then managed through more secure means, such as console access or specific tools like Nutanix Support.

A. Cluster Lockdown:Correct, as this prevents SSH-based access to the CVM.

B. STIG:Incorrect, as STIG (Security Technical Implementation Guide) focuses on broader compliance measures.

C. RBAC Policy on PC:Incorrect, as RBAC (Role-Based Access Control) controls Prism Central permissions, not CVM access.

D. Data-at-Rest Encryption:Incorrect, as this secures stored data, not access credentials.

TheReserved Capacityoption in a storage container explicitly reserves a portion of cluster storage for that container. This reservation reduces the amount of storage available for other containers. Reserved Capacity ensures that specific workloads have guaranteed storage resources, preventing resource contention or overcommitment.

Other options:

Advertised Capacity: Defines the storage limit displayed to users but does not reserve storage.

Erasure Coding: Optimizes storage efficiency but does not reduce available capacity.

Capacity Deduplication: Reduces space consumption by eliminating duplicate data but does not affect other containers' storage.

The Controller VM (CVM) uses thevs0bridge by default to communicate with the AHV host it runs on. Thevs0bridge is a virtual switch configured on the AHV host, providing connectivity between the CVM, virtual machines, and external networks. This setup ensures efficient network communication within the Nutanix cluster.

Other options:

virbro: Typically used in standalone KVM configurations, not in Nutanix AHV.

broandbridge0: Incorrect references to Nutanix networking structures.
