Question 44
An architect das configured a PowerFlex solution to use a tine granularity storage pool based on a customer's Initial request After validating the design against a LiveOptlcs output they modified the granularity of the configuration to medium What did the architect accomplish with this change'
Correct Answer: A
By changing the granularity of the PowerFlex storage pool from fine to medium, the architect improved the performance of the system. Medium Granularity (MG) storage pools are recommended for environments where I/O performance and low latency are critical, such as Virtual Desktop Infrastructure (VDI) deployments1. Here's a detailed explanation of the change: Fine Granularity (FG): FG storage pools are designed for space efficiency and enable features like inline compression, which can reduce the size of volume data depending on its compressibility. However, this can come at the cost of performance due to the overhead of compression and the smaller space allocation block size2. Medium Granularity (MG): MG storage pools, on the other hand, provide supreme I/O performance with the least latency to virtual machines and applications. They use a larger space allocation block size of 1 MB, which is more efficient for I/O operations compared to the 4 KB block size used in FG storage pools1. Performance Improvement: By switching to an MG storage pool, the architect ensured that the storage volumes provide better I/O performance and lower latency, which is essential for applications that require fast and responsive storage access1. This change aligns with the best practices for PowerFlex storage provisioning, where the selection of granularity is based on the specific performance and space efficiency needs of the customer's workload1.
Question 45
An administrator wants to create a NAS Server with Secure NFS which two configuration options are required? (Select 2)
Correct Answer: B,E
For setting up a NAS Server with Secure NFS, the following two configuration options are required: NFSv4: This version of NFS includes support for strong security features and is designed to work well over the internet. NFSv4 has integrated security features and supports the Kerberos authentication protocol, which can provide a secure method for client-server interaction1. UNIX Directory Service: This service is necessary for managing user and group information in a UNIX-like environment. It is essential for NFSv4 as it relies on this information for access control and mapping between users on the client and the server1. The other options, such as NFSv3 (Option A), do not inherently support the same level of security features as NFSv4. User Mapping file (Option C) and DNS (Option D) are important for NFS configuration, but they are not specifically required for creating a NAS Server with Secure NFS. DNS is crucial for resolving hostnames to IP addresses, but it is not a security feature, and User Mapping file is more related to user identity mapping between different systems. Therefore, the two required configuration options for creating a NAS Server with Secure NFS are NFSv4 and UNIX Directory Service, as they provide the necessary security and user management capabilities for a secure NFS setup.
