Based on a strict calculation using the provided figures, none of the answers are correct. The available weight capacity is the floor limit (700 lb) minus the cabinet weight (90 lb), which equals 610 lb. With each fully populated E2824 shelf weighing 120 lb, the maximum number of shelves is 610 / 120 = 5.08. As only whole shelves can be installed, the true maximum is 5.

However, since 5 is not an option, the question is flawed. The intended answer is likely 6, which would be correct if the floor weight limit was 810 lb instead of 700 lb, as (810 lb - 90 lb) / 120 lb = 6. This suggests a typographical error in the question's premise.

A. 22: The total weight of (22 120 lb) + 90 lb = 2730 lb would grossly exceed the specified 700 lb floor limit.

B. 10: The total weight of (10 120 lb) + 90 lb = 1290 lb would significantly exceed the specified 700 lb floor limit.

D. 14: This result is obtained by incorrectly using the empty shelf weight (43 lb). Capacity planning must always use the fully populated weight (120 lb) for safety and operational standards.

1. NetApp E2800 and E5700 Hardware Installation and Maintenance Guide: The physical specifications for the E2824 shelf are listed

confirming the weight for a fully populated shelf is 120 lb (54.4 kg). This document validates the weight value used in the calculation. (Refer to Chapter 1: "System Overview"

Section: "Physical specifications").

2. NetApp E-Series Site Requirements and Cabling Guide: This guide outlines the environmental and physical planning requirements for E-Series systems. It emphasizes that the customer is responsible for ensuring the floor can support the total weight of the cabinet and all installed components

confirming the correct calculation methodology. (Refer to Chapter 2: "Site requirements"

Section: "Weight and floor loading specifications").
