Statement True False DNS servers cache quite aggressively all responses going through them. Modern HTTP versions support persistent connections. Problem 2 (10p) 1 2 3 Router 1 Router 2 DNS Server Laptop Here Consider the network depicted above and a DNS request packet traveling from the laptop on the left to the DNS server on the right. Assume that the packet is captured on the Ethernet link 2 connecting Router 1 to Router 2. This problem is asking you about the layered structure of the packet at that point (on the Ethernet link between Router 1 and Router 2) in its trip from the laptop to the DNS Server. To answer this problem, fill in the table below: Layer Number Layer Name Protocol In That which network element (Laptop, Router 1, Router Layer 2. Server) filled in the information in that layer 5 Application Transport 3 Network 2 Link 1 Physical
