Which two device types does DHCP snooping treat as untrusted in an ISP environment? (Choose two.)

Answer options

• A. provider devices
• B. customer edge devices
• C. user-facing provider edge devices
• D. end host devices
• E. provider edge devices

Correct answer: B, D

DHCP snooping identifies customer edge devices and end host devices as untrusted because they can potentially send rogue DHCP messages, which can disrupt the network. In contrast, provider devices and provider edge devices are typically trusted as they control and manage the network infrastructure.
