正解：C
解説：
Deduplication is most effective withfull clone VMsbecause it reduces redundant data blocks stored on the cluster. Full clone VMs often contain identical OS and application files, making them ideal candidates for deduplication, which optimizes storage usage and improves efficiency.
Other options:
* Server workloads: May benefit from deduplication but not as significantly as full clone VMs.
* Linked Clone VMs: Already share base disk images, so deduplication offers limited benefits.
* Cold data: Deduplication is less effective for data that isn't accessed frequently.

What priority case can be opened to guarantee a 8-hour response for a customer with Production Support?
A. P4
B. P3
C. P1
D. P2
正解：C
解説：
APriority 1 (P1)case guarantees an8-hour response timefor customers with Production Support. P1 cases are designated for critical issues that severely impact business operations or cause a complete system outage, requiring immediate attention from Nutanix Support.
Other priorities:
* P2: High-impact issues but not critical, response time varies.
* P3: Medium impact, typically non-urgent issues.
* P4: Low priority, general inquiries or minor issues.

Which feature allows the ability to enable auto-update for NCC?
A. Pulse
B. LCM Auto Inventory
C. Daily Digest
D. LCM HTTPS
正解：A
解説：
The correct answer isC. Pulse.
Pulseis Nutanix's integrated telemetry and support communication service. WhenPulse is enabled, it provides automatic delivery and updates of Nutanix software tools, including theNutanix Cluster Check (NCC)utility.
This allows the system toautomatically download and apply newer versions of NCCwithout requiring manual intervention.
Clarifications:
* A (LCM HTTPS):Refers to LCM transport protocol, unrelated to NCC updates.
* B (Daily Digest):A reporting feature, not an update mechanism.
* D (LCM Auto Inventory):Related to firmware/software inventory, not to NCC or system utilities.
Prism UI Navigation Path:
Settings > Pulse > Enable Pulse
Official Reference:

* Nutanix Support FAQ
* Excerpt: "NCC auto-update is available when Pulse is enabled, allowing Nutanix to deliver updated NCC versions directly to the cluster."

An administrator needs to verify whether the cluster is protected currently from potential data loss due to a component failure.
From the Prism Element Home dashboard, how should the administrator accomplish this task?
A. Click on Home and then Alerts.
B. Look at the Data Resiliency Status widget.
C. Navigate to the Health dashboard.
D. Select the gear icon and then select Pulse.
正解：B
解説：
To verify if the cluster is currently protected from potential data loss due to a component failure, the administrator should check theData Resiliency Status widgeton the Prism Element Home dashboard. This widget provides real-time information about the cluster's resiliency status, including warnings or errors about data redundancy or protection.
Other options:
* A. Select the gear icon and then select Pulseulse is used for telemetry data, not data resiliency status.
* B. Click on Home and then Alerts:Alerts show specific issues but do not directly indicate the overall resiliency status.
* D. Navigate to the Health dashboard:The Health dashboard provides detailed health checks but does not display the current resiliency status.
