Question

You have built the core of your network using Spanning Tree Protocol. You must ensure that if one of the links between your core switches fails to receive BPDUs it does not mistakenly create a loop. Which feature would you use to ensure BPDUs are always received from neighboring switches to indicate that the remote switch is still alive?

Options

Astorm control
BBPDU control
Croot protection
Dloop protection

Explanation

Peer STP applications running on switch interfaces exchange a special type of frame called a bridge protocol data unit (BPDU). Switches communicate interface information using BPDUs to create a loop-free topology that ultimately determines the root bridge and which interfaces block or forward traffic in the spanning tree. However, a root port elected through this process has the possibility of being wrongly elected. A user bridge application running on a PC can generate BPDUs, too, and interfere with root port To prevent this from happening, enable root protection on interfaces that should not receive superior BPDUs from the root bridge and should not be elected as the root port. root-protection-ex-series.html Exam Code: CompTIA Exam Name: Service Provider, Specialist (JNCIS- , Juniper, Check Point, LPI, Nortel, EXIN and so on.
