Dell EMC Exam D-PSC-MN-01 Topic 3 Question 15 Discussion

The two backend switches that support 100 GbE are:

B . S5232-ON

C . Z9264-ON

Dell EMC Networking S5232-ON:

Features:

A 1U high-density switch with 32 ports of 100 GbE QSFP28.

Supports 10/25/40/50/100 GbE speeds through breakout cables.

Use Cases:

Ideal for high-performance backend networks in PowerScale clusters.

Dell EMC Networking Z9264-ON:

Features:

A 2U switch offering 64 ports of 100 GbE QSFP28.

Provides extensive scalability for large network deployments.

Use Cases:

Suitable for large-scale PowerScale clusters requiring extensive bandwidth.

Why Options A and D Are Incorrect:

A . DCS-7308:

The DCS-7300 series is modular and may support 40/100 GbE, but it's not commonly associated with PowerScale backend networks.

Not a standard recommendation for PowerScale deployments.

D . D4040:

The Dell Networking D4040 is a 40 GbE switch, not supporting 100 GbE natively.

Does not meet the requirement for 100 GbE support.
