EMC Dell XtremIO Operate Achievement Sample Questions (Q41-Q46):

NEW QUESTION # 41
Which Linux/UNIX command is used for monitoring the performance of system input/output devices?

A. netstat
B. stat
C. iostat
D. nbtstat

Answer: C

Explanation:
The iostat command is used for monitoring system input/output device loading by observing the time the devices are active in relation to their average transfer rates.It generates reports that can be used to change system configuration to better balance the input/output load between physical disks1.The iostat command is particularly useful for monitoring disk throughput and can help identify high disk utilization, which is essential for diagnosing performance issues related to storage2.
The iostat command provides information about input/output (I/O) statistics for block devices (like hard drives and SSDs) and CPUs, making it a valuable tool for analyzing the performance and usage of these resources on a system1.It is distributed as part of the sysstat package and is available on most Linux distributions1.
The other commands listed have different purposes:
* stat (OA) is used to display file or file system status.
* netstat (OB) displays network connections, routing tables, interface statistics, masquerade connections, and multicast memberships.
* nbtstat (OC) is a Windows command-line utility that displays protocol statistics and current TCP/IP connections using NetBIOS over TCP/IP.
Therefore, for monitoring the performance of system input/output devices on Linux/UNIX systems, iostat (OD) is the correct command to use1.

NEW QUESTION # 42
How many major report categories are in the XtremIO X2 WebUI?

A. 0
B. 1
C. 2
D. 3

Answer: C

Explanation:
* The XtremIO X2 WebUI features 7 major report categories, providing comprehensive insights into various aspects of the storage environment.
* These report categories cover performance metrics, capacity usage, efficiency statistics, and more, aiding administrators in effective management and optimization of the storage array.

NEW QUESTION # 43
If a systems administrator needs to create a new XtremlO report, what is the minimum account role required?

A. Administrator
B. Read Only
C. Configuration
D. Technician

Answer: A

Explanation:
In the context of XtremIO storage systems, creating reports typically requires administrative privileges. The role of an Administrator is usually necessary to access and manage the full range of system functionalities, including the generation of new reports. Here's why:
* Configuration Role (OA): While this role may allow for some system configurations, it might not have the necessary permissions to create new reports, which often involve accessing and manipulating system-wide data.
* Read-Only Role (B): This role is typically limited to viewing configurations and reports that already exist within the system. It does not permit the creation of new reports or modification of existing ones.
* Administrator Role (OC): An Administrator role usually has the highest level of access within a system, including the ability to create, modify, and delete reports. This role can access all areas of the system and make changes as required.
* Technician Role (OD): The Technician role may have permissions for certain operational tasks and troubleshooting but is not typically empowered to create system reports.
Therefore, the minimum account role required to create a new XtremIO report would be the Administrator role (OC), as it provides the necessary access and permissions to perform such tasks within the storage system.

NEW QUESTION # 44
What is a specific configuration guideline that should be followed when configuring Linux hosts to support XtremIO storage?

A. Enable the I/O elevator
B. Set the execution throttle to 35025
C. Assign LUN 0 to the boot LUN
D. Set the LUN queue depth to 64

Answer: D

Explanation:
* Configuring Linux hosts to support XtremIO storage involves setting the LUN queue depth to 64.
* This configuration ensures optimal performance by allowing the host to handle multiple I/O operations concurrently, matching the capabilities of the XtremIO array.
* Proper tuning of the LUN queue depth is crucial for maximizing throughput and minimizing latency in high-performance storage environments.

NEW QUESTION # 45
You are creating a virtual disk for a VMware VM running on vSphere 6.5. The VM will reside on a datastore provisioned from an XtremlO volume. You want to ensure proper performance and capacity usage.
How should the disk be presented to the guest?

A. Thick Provisioned, Eager Zero
B. Thin Provisioned
C. Raw Device Mappings
D. Thick Provisioned, Lazy Zero

Answer: A

Explanation:
When creating a virtual disk for a VMware VM that will reside on a datastore provisioned from an XtremIO volume, it is generally recommended to use Thick Provisioned, Eager Zeroed disks for optimal performance and capacity usage. Here's why:
* Thick Provisioned, Eager Zeroed (OC): This type of disk allocation pre-allocates the entire size of the disk and zeroes out all the blocks at the time of creation.This can lead to better performance because all the space is allocated and ready for use, and there is no overhead associated with zeroing out blocks during write operations1.
* Thick Provisioned, Lazy Zero (OA): While this also pre-allocates the entire disk size, it does not zero out the blocks until they are first written to.This can lead to potential performance degradation compared to Eager Zeroed disks when the blocks are zeroed on demand1.
* Thin Provisioned (OB): Thin provisioning allocates disk space on demand rather than pre-allocating the entire disk size.While this can be more efficient in terms of capacity usage, it may not provide the same level of performance as Thick Provisioned, Eager Zeroed disks, especially in high I/O environments1.
* Raw Device Mappings (OD): RDM allows a VM to directly access a LUN on the SAN.This is typically used for specific use cases that require direct access to the physical storage device and is not generally necessary for standard VM deployments1.
In summary, for ensuring proper performance and capacity usage, Thick Provisioned, Eager Zeroed (OC) is the recommended way to present the disk to the guest for a VMware VM running on vSphere 6.5 with an XtremIO volume1.
