Which NAS protocols does Dell PowerStore support?
- A . FTP, SMB, NFSv2, NFSv3, and FTPS
- B . FTPS, SMB, NFSv3, NFSv4, and FTP
- C . SMB, NFSv3, NFSv4p, FTP, and SFTP
- D . NFSv4, SMB, S3, FTP, and SFTP
C
Explanation:
Dell PowerStore supports a variety of NAS protocols to provide file access to clients.
These protocols include:
✑ SMB (Server Message Block): This protocol is used to provide file and printer sharing on Windows-based systems.
✑ NFSv3 (Network File System version 3): This is a standard protocol used to provide file access on UNIX-based systems.
✑ NFSv4 (Network File System version 4): This is the latest version of the NFS protocol and it provides enhanced security and improved performance over previous versions.
✑ FTP (File Transfer Protocol): This is a standard protocol used to transfer files between computers over a network.
✑ SFTP (Secure File Transfer Protocol): This is an extension of the FTP protocol that provides secure file transfer using SSH (Secure Shell) encryption.
A customer wants to expand their Dell Unity XT All Flash system, which includes a pool of 64 drives in a RAID 5 (4+1) configuration.
What is the minimum number of drives needed to expand the pool?
- A . 1
- B . 7
- C . 5
- D . 6
What are the two biggest factors that determine IOPS when using SSDs in a Dell EMC SC Series array?
- A . Current latency and queue depth
- B . Application block size and overall throughput
- C . Multi-tenant arrays and tier configuration
- D . Read/write percentage and peak workload
B
Explanation:
The reason there is such a large range in the number of IOPS delivered by SSDs is the IOPS are truly dependent on the type of traffic the SC Series was designed to handle. The two biggest factors that will determine IOPS in an SSD environment are block size of the application and overall throughput.
