Free Juniper JN0-105 Actual Exam Questions - Question 10 Discussion

Option B and D, as Ethernet frames only use MAC addresses for source and destination.

Probably B and D since Ethernet frames only carry MAC addresses in the header.

B/D? Since the question asks specifically about the Ethernet frame header, it’s definitely about MAC addresses. The IP addresses are part of the layer 3 packet inside the frame, so they don’t belong in the Ethernet header. So options B and D fit perfectly while A and C are out.

Probably D and B here. The frame header is all about the MAC addresses for source and destination since IP addresses are part of the packet inside, not the Ethernet frame itself. So A and C can be ruled out because they refer to IPs, which come later in the protocol stack.

B/D, since Ethernet frames deal with physical addressing, not IPs.

B/D for sure. Ethernet frames use MAC addresses to identify devices on the local network, so IP addresses wouldn’t be in the frame header itself.

It’s kinda tricky since IP addresses aren’t part of the Ethernet frame header. The answer should definitely include MAC addresses, so B and D seem right here.
