質問 # 45
What is the main function of Oplog?
- A. A persistent write buffer to coalesce bursts of random writes before destaging to the extend store
- B. A persistent write buffer to coalesce all writes before destaging to the extent store
- C. A memory cache to coalesce all writes before destaging to the extent store
- D. A memory cache to coalesce bursts of random writes before destaging to the extent store
正解：A
解説：
The main function of Oplog in Nutanix is to act as a persistent write buffer to coalesce bursts of random writes before they are destaged to the extent store. This mechanism improves write performance and reduces latency by temporarily storing write operations in a fast, dedicated buffer before committing them to the slower, persistent storage.

D: Use a single interface to manage and monitor the full stack:
* One of Nutanix's key advantages is the ability to manage and monitor the entire infrastructure stack from a single interface, Prism. This feature simplifies management and reduces operational overhead, which aligns with the customer's requirement for an "All in One" solution.
質問 # 50
In addition to the total number of physical CPU cores, which hardware component is used to calculate the cost of Capacity Based Licensing for a Nutanix Cluster?
- A. RAM (in TiB)
- B. RAW total storage (in TiB)
- C. RAW SSD storage (in TiB)
- D. RAW HDD storage (in TiB)
正解：B
解説：
In addition to the total number of physical CPU cores, the cost of Capacity Based Licensing for a Nutanix Cluster is calculated using the RAW total storage in TiB. This approach ensures that both computational and storage resources are accounted for when determining the licensing costs.
* Physical CPU Cores: The number of physical CPU cores is the primary factor in the licensing cost calculation.
* Raw Total Storage: This includes the total raw capacity of all storage devices (both SSDs and HDDs) present in the cluster, measured in tebibytes (TiB).
References:
* Nutanix Licensing Guide: Details the parameters considered for capacity-based licensing.
* Nutanix Community and Support Documentation: Provides insights into licensing models and their components.

質問 # 56
An administrator has been alerted to a VM that has high I/O latency and wants to determine if there are any other factors, such as insufficient network or memory resources that correlate, as part of a troubleshooting process.
Which type of chart should the administrator create to allow all relevant data to be easily exported to CSV for later analysis?
- A. A VM entity chart with each of the relevant metrics.
- B. A cluster entity chart with each of the relevant metrics
- C. A VM metric chart for each of the relevant metrics
- D. A cluster metric chart for each of the relevant metrics
正解：A
解説：
To troubleshoot high I/O latency and correlate it with other potential resource issues, such as network or memory constraints, the administrator should create a VM entity chart. This type of chart allows for:
* Inclusion of Multiple Metrics:
* The VM entity chart can incorporate various relevant metrics such as I/O latency, CPU usage, memory usage, and network throughput, providing a comprehensive view of the VM's performance.
* Ease of Data Export:
* The chart can be easily exported to CSV format, facilitating detailed offline analysis. This is essential for correlating different metrics over the same time period and identifying patterns or anomalies that could explain the high I/O latency.
By using a VM entity chart, the administrator ensures that all pertinent data is collected and can be analyzed together, providing a holistic view of the VM's performance and aiding in pinpointing the root cause of the latency issue.

質問 # 57
A customer performs a 1-click, non-disruptive upgrade on a 3-node Nutanix cluster. While the CVM on Node A is rebooting, a VM on Node A overwrites an existing block of data. How does Nutanix AOS ensure data integrity during the upgrade?
- A. AOS writes two copies across the remaining nodes to maintain resiliency
- B. AOS leverages Erasure Coding to maintain resiliency.
- C. AOS only overwrite the available copy and waits until the original copy is back online before restoring resiliency
- D. AOS marks the replica as read only and waits until the original replica is back online to prevent corruption.
正解：A
解説：
During a 1-click, non-disruptive upgrade on a 3-node Nutanix cluster, if a VM on Node A overwrites an existing block of data while the CVM on Node A is rebooting, Nutanix AOS ensures data integrity by writing two copies of the data across the remaining nodes. This approach maintains data resiliency by ensuring that multiple copies of the data are available even when one of the nodes is temporarily unavailable.
