Pregunta 22 de 28
22. Pregunta
22. Match the steps with the actions that are involved when an internal host with IP address 192.168.10.10 attempts to send a packet to an external server at the IP address 209.165.200.254 across a router R1 that is running dynamic NAT. (Not all options are used.)
Ordenar elementos
- R1 replaces the address 192.168.10.10 with a translated inside global address.
- R1 checks the NAT configuration to determine if this packet should be translated.
- R1 selects an available global address from the dynamic address pool.
- The cost sends packets that request a connection to the server at the address 209.165.200.254
- If there is no translation entry for this IP address, R1 determines that the source address 192.168.10.10 must be translated.
