Refer to the exhibit. A cybersecurity analyst is viewing captured packets forwarded on switch S1. Which device has the MAC address d8:cb:8a:5c:d5:8a?router
- DG
- PC-A
- router ISP
- web server
- DNS server
Answers Explanation & Hints:
The Wireshark capture is a DNS response from the DNS server to PC-A. Because the packet was captured on the LAN that the PC is on, router DG would have encapsulated the response packet from the ISP router into an Ethernet frame addressed to PC-A and forwarded the frame with the MAC address of PC-A as the destination. |
