352-001 · Question #117
Refer to the exhibit. What limitations exist in this design, given that the access layer devices are expected to steadily increase by two devices per week for the next year?
The correct answer is A. scalability. A steady increase of two access layer devices per week for a year adds roughly 104 new devices, which exposes the design's inability to grow without architectural changes.

Why each option
A steady increase of two access layer devices per week for a year adds roughly 104 new devices, which exposes the design's inability to grow without architectural changes.
Scalability is the limitation because the design has a fixed capacity at the access layer - adding approximately 104 devices over a year will exhaust port density, uplink bandwidth, and potentially spanning-tree or routing table limits. A scalable design would require modular expansion, additional distribution switches, or a redesigned topology to absorb that growth without degradation.
Serviceability refers to ease of maintenance and troubleshooting, which is not affected by simply adding more access devices.
Redundancy concerns duplicate paths and failover mechanisms, not the capacity to accommodate device growth.
Resiliency refers to the ability to recover from failures, which is a separate concern from the inability to scale to new devices.
