NEW QUESTION # 63
ABC Corp currently has 50 VMs currently running in production and is interested in sizing a DR cluster. The RTO is 4 hours and the RPO is 2 hours .
Each VM has 100GB of data, with a 5% daily change rate .for retention the customer wants to keep 2 weeks of snaps on the DR cluster.
What is the minimum amount of storage capacity for the remote cluster to meet the customer's data retention
- A. 10TB to 11TB
- B. 14TB to 15T
- C. 8TB to 9TB
- D. 6TB to 7TB
Answer: B
Explanation:
* Calculate Daily Change Rate Data:
* Each VM has 100GB of data.
* Daily change rate is 5%.
* For 50 VMs: 50×100×0.05=25050 \times 100 \times 0.05 = 25050×100×0.05=250 GB of daily changed data.
* Calculate Snapshot Data:
* Daily snapshots for retention of 2 weeks (14 days).
* Total snapshot data for 14 days: 250×14=3500250 \times 14 = 3500250×14=3500 GB or 3.5 TB.
* Calculate Full Data Storage:
* Each VM has 100GB.
* For 50 VMs: 50×100=500050 \times 100 = 500050×100=5000 GB or 5 TB.
* Total Storage Required:
* Sum of snapshot data and full data storage: 3.5 TB+5 TB=8.5 TB3.5 \text{ TB} + 5 \text{ TB} =
8.5 \text{ TB}3.5 TB+5 TB=8.5 TB.
* Additional Factors and Overhead:
* Typically, an overhead of approximately 60-70% of the used space is recommended to accommodate additional requirements such as metadata, system usage, and unexpected data growth.
* Adding overhead: 8.5 TB×1.6=13.6 TB8.5 \text{ TB} \times 1.6 = 13.6 \text{ TB}8.5 TB×1.6=13.6 TB.
Thus, the minimum amount of storage capacity for the remote cluster to meet the customer's data retention is approximately 14TB to 15TB.

* Considerations for overhead and additional storage needs as per standard data management best practices.
NEW QUESTION # 64

- C. AOS only overwrites the available copy and waits until the origninal copy is back online before restoring resiliency.
- D. AOS leverages Erasure Coding to maintain resiliency.
Answer: A
NEW QUESTION # 65
An administrator is managing a highly active SQL workload that is writing I/Os in 2 MB chunks to a vDisk. The administrator wants to optimize capacity setting for the computer.
Which storage optimization technology should the administration select to meet these requirement?
- A. Erasure Coding

Answer: B
NEW QUESTION # 66
In which scenario should shadow clones be explicitly disabled?
- A. when deploying an Oracle RAC database
- B. when deploying Splunk
- C. when deploying Citrix virtual desktops
- D. when deploying Horizon View virtual desktops
Answer: A
Explanation:
C: When deploying an Oracle RAC database:
* Shadow clones should be explicitly disabled when deploying an Oracle RAC database. Oracle RAC requires highly consistent and low-latency storage access, and enabling shadow clones can introduce additional latency and potential inconsistencies that are unsuitable for such databases.
* Shadow clones are designed to enhance performance for read-heavy workloads by caching frequently accessed data locally. However, Oracle RAC's stringent requirements for data consistency and latency make this feature inappropriate for its deployment.
NEW QUESTION # 67
A prospective customer is evaluating solutions to support a project. The systems engineer proposes a hybrid model as recommended by Sizer. The prospect is concerned about the performance of a hybrid configuration and is evaluating an all flash array.
Which two Nutanix features should be discussed to address the concerns of the prospective customer' (Choose two.)
- A. Automatic Data Tiering
- B. AHV Turbo Mode
- C. Data Locality

NEW QUESTION # 68
A prospect is evaluating Nutanix for a large number of Oracle RAC deployments. Time to deployment is a top priority, and the prospect has developed a self-service tool in-house to expedite these deployments.
Which Nutanix feature should be discussed?
- A. ABS
- B. Calm
- C. REST API
- D. Xtract for Databases
Answer: C
Explanation:
A prospect evaluating Nutanix for a large number of Oracle RAC deployments, prioritizing time to deployment and utilizing an in-house self-service tool, would benefit most from Nutanix's REST API capabilities. Here is a detailed explanation:
* Requirement Analysis:The prospect needs a solution that allows rapid deployment of Oracle RAC environments and integrates with their existing self-service deployment tool. This means the feature should support automation and programmatic control.
* Feature Analysis:
* Calm: While Nutanix Calm can orchestrate and automate application deployments, including complex multi-tier applications, the existing self-service tool of the prospect may make Calm redundant for this specific need.
* Xtract for Databases: This tool assists in migrating databases to Nutanix but is not directly involved in deploying new Oracle RAC instances.
* ABS (Acropolis Block Services): ABS provides block storage services to external physical and virtual machines but is not focused on deployment automation.
* REST API: Nutanix's REST API offers extensive programmatic control over various functions, including provisioning, managing, and configuring Nutanix environments. It allows the integration of custom tools to automate and expedite deployments effectively.
* Conclusion:Given the requirement for rapid deployment through an existing self-service tool, Nutanix REST API is the most appropriate feature to discuss. It provides the necessary flexibility and integration capabilities for automated deployments.
