Which two functions are performed by the core layer in a three-tier architecture? (Choose two)
Choose 2 — select all that apply
AProvide uninterrupted forwarding service.
BPolice traffic that is sent to the edge of the network.
CProvide direct connectivity for end user devices.
DEnsure timely data transfer between layers.
EInspect packets for malicious activity.
Correct Answer:AD
Cisco is very clear about the purpose of this layer. Its only role is to forward traffic, the fastest it can. Here you don’t apply any policy, as you must try to reduce the load of the core so it can focus on routing. https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Campus/campover.html#wp708831

Refer to the exhibit. After the election process what is the root bridge in the HQ LAN? A. Switch 1
BSwitch 2
CSwitch 3
DSwitch 4
Correct Answer:C
The root bridge is determined by the lowest bridge ID, which consists of the priority value and the MAC address. Because the priority values of all of the switches are not avalable, the MAC address is used to determine the root bridge. Because S3 has the lowest MAC address, S3 becomes the root bridge.
