, Question 1. (Multi Select)
A university lab switch shows two recurring problems on its access ports. One port occasionally floods the
segment with broadcast traffic from a faulty adapter, and students attach small hubs that push the switch's
forwarding table toward exhaustion.
Which two mechanisms address these problems respectively?
(Choose two.)
A: Port security, which caps how many distinct source MAC addresses one access port may learn
B: MAC flapping detection, which blocks a port when an address keeps moving
C: BPDU protection, a spanning tree safeguard configured on the access ports that face end users
D: Loop detection, which disables a port that receives a frame the switch itself sent
E: Storm control, which discards broadcast frames on a port once their rate passes the configured limit
Answer: A, E
Question 2. (Single Select)
A campus WLAN uses a central controller. The security team requires that all wireless user traffic pass a
single enforcement point before reaching the wired network, and the same SSID must be offered from
access points in several buildings that sit in different wired subnets.
Which forwarding design meets both requirements, and what does it cost?
A: Tunnel forwarding, which keeps management traffic on the controller while user traffic exits locally, at the
cost of duplicating policy.
B: Direct forwarding, which places user traffic onto the local wired segment at each access point, at the
cost of a longer path back to the controller.
C: Tunnel forwarding, which carries user traffic to the controller for enforcement, at the cost of
concentrating load and lengthening the path.
D: Direct forwarding, which extends a single broadcast domain across every building, at the cost of
controller processing.
Answer: C
