Problem Statement

Shared context — identical in all four questions in this set. The scenario and artifacts below are exactly the same across all four questions; only the Question section changes. If you have already read them in another question, skip straight to Question . A campus network has the following topology: Host A (10.1.1.10, VLAN 10) — Switch S1 — Router R1 — Switch S2 — Host B (10.2.2.20, VLAN 20) Switch S1 is a Layer-2 switch serving VLAN 10. Router R1 has two interfaces: eth0: 10.1.1.1 (gateway for VLAN 10), MAC = AA:AA:AA:00:01:01 eth1: 10.2.2.1 (gateway for VLAN 20), MAC = AA:AA:AA:00:02:01 Switch S2 is a Layer-2 switch serving VLAN 20. Host A: IP = 10.1.1.10, MAC = BB:BB:BB:00:01:10, default gateway = 10.1.1.1 Host B: IP = 10.2.2.20, MAC = CC:CC:CC:00:02:20, default gateway = 10.2.2.1 Host A sends an HTTP request to Host B. Assume all ARP caches are fully populated. Question As the frame leaves Host A toward Switch S1, what are the source MAC , destination MAC , source IP , and destina
