Question 2
What are differences between the Dell Unity XT 380F array and the Dell Unity XT 880F array?
Answer : A
The Dell Unity XT 380F array is equipped with converged network adapter (CNA) ports, while the Dell Unity XT 880F array features embedded mezzanine ports. These differences in port configurations reflect the varied performance and connectivity options available in different models of the Unity XT series.

Question 3
What initiates an automatic NAS server failover to the peer SP?
Answer : C
An automatic NAS server failover to the peer Storage Processor (SP) is initiated by an SP hardware fault. This failover mechanism ensures high availability and continuous access to data by moving the NAS server's operations to the functioning SP when a hardware fault is detected in the primary SP.

Question 4
Which Dell Unity XT DPE front-end port connectivity can support up to 30,000 IOPS/port and up to 1,700 MB/s?
Answer : B
16 Gb Fibre Channel (FC) front-end port connectivity on Dell Unity XT DPE can support up to 30,000 IOPS per port and up to 1,700 MB/s. This level of performance makes it suitable for high-demand enterprise applications that require robust and fast storage networking.

Question 5
Which backend port are required to expand the PowerStore x200 models to have NVMe Expansions?
A solution architect notices the PowerSizer is translating File Operations into IOPS for cluster and appliance summary details. IOPS are not impacting the summary MiB/s. What is the cause of this issue?
Answer : B
The issue arises because File Operations were entered into the PowerSizer tool, but MiB/s (Megabytes per second) was not entered. This causes the tool to translate File Operations into IOPS (Input/Output Operations Per Second) for the cluster and appliance summary details, but since MiB/s was not entered, it does not impact the summary throughput (MiB/s). Here's the detailed explanation:
File Operations Entry: When file operations are entered, the tool calculates the corresponding IOPS to summarize the workload's impact on the system.
MiB/s Entry Missing: If the MiB/s value is not provided, the tool cannot incorporate this metric into the overall summary, leading to a mismatch where IOPS are calculated but do not affect the MiB/s summary.
Which two statements are correct for a PowerStore 5200T with mixed SSD and SCM drive combination? (Select 2)
Answer : A, D
For a PowerStore 5200T system with a mixed SSD and SCM (Storage Class Memory) drive combination, the following statements are correct:
Expansion Enclosures are supported: PowerStore 5200T supports expansion enclosures, allowing for the addition of more drives to increase storage capacity and performance. This flexibility is crucial for scaling the storage system to meet growing data requirements.
SCM drives do not add to usable capacity: SCM drives in the PowerStore 5200T are primarily used for caching purposes rather than for adding to the system's usable capacity. These drives improve performance by accelerating data access times but do not contribute directly to the overall storage capacity.
