Sample question 1 — Security
A coworking site rents small offices and gives each tenant one wall port. Tenants move laptops, phones, and a desk phone between desks, and the operations team cannot predict which device will appear on which port. The team wants each port capped at four learned addresses, with the current devices remembered after the switch is reloaded. Which configuration meets both goals?
- A. Set maximum 4 with restrict mode and no persistent learning at all
- B. Set maximum 4 with sticky learning so learned addresses persist
- C. Set maximum 1 with shutdown mode on every tenant-facing access port
- D. Set maximum 4 with every port trusted as an uplink to the core
Answer: B. Sticky learning with a maximum of four addresses caps each port, and the learned addresses persist in the running configuration once it is saved. Restrict mode limits the port but keeps no persistent entries, and a maximum of one blocks the phone and laptop that share a desk. Trusting every port as an uplink removes the limit entirely.
