Refer to the exhibits.
Exhibit 1. Existing wiring plan:
Exhibit 2. Current proposal:
A customer has a building that needs a switch upgrade. The customer would like at least 20Gbps for the uplink bandwidth out of each closet. The building writing plan is shown in Exhibit 1. The customer will not consider any cable upgrades at this point. The current proposal is shown in Exhibit 2.
Which correction must architect make to the proposal to meet the customer requirements?
The existing wiring plan shows that the connections within each floor use CAT5e cables, which are copper cables. The customer wants at least 20Gbps for the uplink bandwidth, but the current proposal does not seem to account for these copper cables. Option B suggests adding an aggregation layer and connecting the closet switches to this layer using Smart Rate ports, which is a suitable method as Smart Rate ports can support higher speeds over existing copper cabling. Therefore, adding an aggregation layer with Smart Rate ports addresses the requirement without needing cable upgrades.
Should be B right? You do not even have fiber on the floors so how would a mode conditioning patch cable help?
Since you have only copper to the other floors, smart-rate iss the only option.
