The correct answer is C. configure spanning-tree with bpdu-guard timeout values for CCTV switch ports. Since the CCTV switches don't run STP, Edge-1 should protect itself from potential loops by enabling STP on those ports and using BPDU-guard with an automatic timeout/recovery. If a looped switch starts sending BPDUs, the port is error-disabled, then automatically recovers after
Question
Refer to the exhibit. VSX cluster is already configured. Your task is to validate a correct configuration for the Edge-1 switch that is connected to a CCTV provider that will install its switching infrastructure. The CCTV switches do not support STP. What needs to be configured on the Edge-1 switch ports connecting to CCTV-SW1 and CCTV- SW2 to prevent loop problems with the existing setup with automatic recovery features?
Exhibit
Options
- Aconfigure lag with lacp fallback for CCTV switch ports
- Bconfigure spanning-tree and TN-guard timeout for CCTV switch ports
- Cconfigure spanning-tree with bpdu-guard timeout values for CCTV switch ports
- Dconfigure spanning-tree with udld for CCTV switch ports

Explanation
Since the CCTV switches don't run STP, Edge-1 should protect itself from potential loops by enabling STP on those ports and using BPDU-guard with an automatic timeout/recovery. If a looped switch starts sending BPDUs, the port is error-disabled, then automatically recovers after
