At ValidExamDumps, we consistently monitor updates to the Dell EMC D-PST-DY-23 exam questions by Dell EMC. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Dell EMC Dell PowerStore Deploy 2023 exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Dell EMC in their Dell EMC D-PST-DY-23 exam. These outdated questions lead to customers failing their Dell EMC Dell PowerStore Deploy 2023 exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Dell EMC D-PST-DY-23 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Which configuration item is optional during the PowerStore ICW?
Core service components that are required to be initialized are Telemetry Notice, Cluster Details, Default Users, Fault Tolerance, Management Network, Infrastructure Services, and Create Cluster. As a result of successful core initialization steps, a cluster is created, but not fully configured. (P59 of POWERSTORE 3.0 POWERSTORE T IMPLEMENTATION)
Which two operations does the PowerStore NAS VAAI plug-in support? (Choose two.)
A storage administrator provisions a VMware file system from a NAS server configured with NFSv4.
What is the access requirement for the ESXi host?
NFSv4 and ESXi Host Access
When provisioning a VMware file system (like a datastore) from a NAS server using NFSv4, the ESXi host needs specific permissions to function correctly:
Read/Write Access: This is fundamental. The ESXi host must be able to both read data from and write data to the datastore. This is essential for storing virtual machine files, writing logs, and managing the overall file system.
Allow Root Access: ESXi hosts require root-level access to the NFS datastore. This is critical for:
Creating and Managing VMDKs: Root access is necessary to create, delete, and modify virtual machine disk files (VMDKs) on the datastore.
Managing VM Files: The host needs root permissions to manage various virtual machine configuration files and logs stored on the datastore.
Maintaining File System Integrity: Root access allows the ESXi host to perform essential file system operations to ensure consistency and prevent data corruption.
Why Other Options Are Incorrect
A . Read/Write: While read/write access is necessary, it's not sufficient on its own. Root access is also required.
B . Kerberos with Integrity: Kerberos is a security protocol that can be used with NFSv4 for authentication, but it's not a basic access requirement for ESXi hosts. While Kerberos enhances security, it's not strictly mandatory for basic functionality.
C . Kerberos with Encryption: Similar to Kerberos with integrity, encryption adds another layer of security but isn't a fundamental requirement for ESXi host access to an NFSv4 datastore.
Important Considerations
NFS Owner: When configuring NFSv4 on PowerStore, you typically set the 'NFS Owner' to 'root' for ESXi hosts. This ensures that the host has the necessary permissions.
no_root_squash: On some NAS systems, you might need to configure the no_root_squash option in the NFS export settings. This option prevents the NAS server from mapping the root user on the ESXi host to a less privileged user, ensuring that the host retains root access to the NFS share.
