Prueba CAP 5 Nat

The correct answer is NAT dinamica. This type of NAT allows the router to dynamically assign unique public IP addresses to the computers on the internal network while they send packets to the Internet through the router. This means that each computer on the internal network will have a different public IP address when communicating with external networks.

A router habilitado para PAT utiliza el número de puerto TCP o UDP de destino en el paquete entrante para enviar los paquetes a los hosts internos correctos. Esto se debe a que el PAT (Port Address Translation) es una técnica de traducción de direcciones de red que permite a múltiples dispositivos en una red privada compartir una única dirección IP pública. Al utilizar el número de puerto de destino en el paquete entrante, el router puede determinar qué host interno debe recibir el paquete y realizar la traducción de direcciones correspondiente.

The given configuration uses a pool of IP addresses ranging from 209.165.201.23 to 209.165.201.30 with a netmask of 255.255.255.224. This netmask allows for 30 IP addresses in total, but the first and last addresses are reserved for network and broadcast addresses respectively. Therefore, there are 30 - 2 = 28 usable addresses. However, the configuration only specifies a pool with 8 addresses (209.165.201.23 to 209.165.201.30), so the number of available addresses for dynamic NAT translation is 8.

One possible reason for the lack of connectivity between the web server and the users on the internet is that the NAT configuration on the router has an incorrect internal local address. This means that the router is not properly translating the internal IP addresses of the web server to the external IP addresses required for communication with the internet users. As a result, the packets sent from the web server are not reaching their intended destinations, leading to the lack of connectivity.

The correct answer is una lista de acceso con el número 4 que defina las direcciones privadas que son afectadas por NAT. This is because the command "ip nat inside source list 4 pool corp" is used to configure NAT (Network Address Translation) on the router. The "list 4" refers to an access control list (ACL) that is used to define the private addresses that will be affected by NAT. By specifying this ACL, the router will know which private addresses to translate to public addresses when performing NAT.

The possible reason why the addresses in the network are not translated despite the router R1 being configured for PAT is that the access list 1 is configured incorrectly.

The correct answer is "Router# show ip nat translations". This command will display the translations of the Network Address Translation (NAT) active on the border router. By using this command, the network administrator can view the NAT translations and gather information about the IP addresses and ports being translated.

The correct answer is that the interface S0/0/0 should be identified as the NAT exterior interface. This means that this interface is connected to the external network, such as the internet, and is responsible for translating the internal IP addresses to the external IP addresses. The NAT exterior interface is the interface through which the traffic leaves the network and enters the external network.

The correct answer is "La dirección IP de un host interno según aparece a la red interna". This means that when setting up the Net on a Cisco router, the local internal IP address is the IP address of an internal host as it appears to the internal network. This implies that the router assigns an IP address to the internal host for communication within the internal network.

The given question asks for the internal global address after PC10 sends a request to the web server. The correct answer is 209.165.200.225.

The correct answer is that the source device is PC10, and the destination port is 80. This can be determined by analyzing the illustration provided, which likely shows network traffic data. The source device is identified as PC10, and the destination port is indicated as port 80.

The reason the request fails is that the IP address of PC20 is not included for NAT translation in Router B.

The correct answer is "Es un mecanismo temporal para asistir en la migración de IPv4 a IPv6." This means that NAT for IPv6 is a temporary mechanism used to assist in the migration from IPv4 to IPv6. NAT allows for the translation of IPv4 addresses to IPv6 addresses, enabling communication between devices using different IP versions. However, it is important to note that NAT is not a long-term solution and is intended to be used during the transition period from IPv4 to IPv6.

El propósito de introducir el comando "ip nat inside source static tcp 192.168.10.2 80 209.165.200.223 8080" en la petición de configuración global es vincular la dirección local interna (192.168.10.2) y el puerto local (80) a la dirección global interna especificada (209.165.200.223) y al puerto global (8080). Esto permite que las solicitudes entrantes dirigidas a la dirección global y al puerto global sean redirigidas a la dirección local y al puerto local correspondientes.

The correct answer is PAT. PAT stands for Port Address Translation, which is a type of address translation used in routers. It allows multiple devices on a local network to share a single public IP address. In PAT, the router assigns a unique port number to each device on the local network, which allows incoming data packets to be correctly routed to the appropriate device. This helps conserve the limited number of public IP addresses available and is commonly used in home and small office networks.

NAT (Network Address Translation) tiene dos beneficios principales: guarda direcciones IP públicas y agrega un grado de privacidad y seguridad a una red. Al utilizar NAT, las direcciones IP públicas se pueden conservar y reutilizar en lugar de tener que asignar una dirección IP pública única a cada dispositivo en la red. Además, NAT oculta las direcciones IP privadas de los dispositivos internos, lo que proporciona una capa adicional de seguridad y privacidad al ocultar la estructura de la red interna.

La NAT dinámica permite a los host recibir la misma dirección global cada vez que se requiere un acceso externo. Esto significa que cuando un host en una red privada necesita comunicarse con un servidor externo, la NAT dinámica asignará una dirección IP global temporal al host. Esta dirección IP global se utilizará para la comunicación externa y se mantendrá constante mientras dure la sesión. Sin embargo, una vez que se termine la sesión, la dirección IP global se liberará y estará disponible para otros hosts en la red.
