DHCP

Issue the command ip helper-address 10.10.200.10 on the router interface that is the 10.10.100.0/24 gateway.

A host on the 10.10.100.0/24 LAN is not being assigned an IPv4 address by an enterprise DHCP server with the address 10.10.200.10/24. What is the best way for the network engineer to resolve this problem?

public IP addresses

A router implementing NAT will contain a pool of what type of addresses?

10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255

According to RFC 1918. Which of the following network addresses are considered part of the private address space?

Verify that the ip helper-address command is configured on the correct interface. Verify that the global configuration command no service dhcp has not been configured.

Administrators can eliminate an issue with the ip helper-address command by performing which of the following?

1. 192.168.1.2:24440 2. 10.1.1.5:23

Based on the output below. What address is the internal host attempting to access on the internet, and how does the internet host see the internal host? Using show ip nat translations

I don't know if this is it. source port: 23 outside port: 24440.

Based on the output below. What is the source and destination port used when the NAT_Router communicates with the internet host?

172.30.20.1:3333

Refer to diagram 1. R1 is performing PAT for the 10.1.1.0 /24 inside network. Host A has sent a packet to the web server. What is the destination IP address of the return packet from the web server when first received at R1?

The pool of addresses for the 192Network pool is incorrect.

Refer to the exhibit. A host connected to Fa0/0 is unable to acquire an IP address from this DHCP server. The output of the debug ip dhcp server command shows "DHCPD: there is no address pool for 192.168.1.1". What is the problem?

The pool of addresses for the 172Network pool is incorrect.

Refer to the exhibit. A host that is connected to Fa0/0 is unable to acquire an IP address dynamically from the DHCP server. The output of the debug ip dhcp server command shows "DHCPD: there is no address pool for 172.16.1.1". What is the problem?

stateless DHCPv6

Refer to the exhibit. Based on the output that is shown, what kind of IPv6 addressing is being configured?

ip nat inside source static 192.168.0.10 172.16.76.3

Refer to the exhibit. Which configuration command would result in the output in the exhibit?

Static NAT

What translation method will allow a server on the inside network to always keep the same public address?

Define the pool of public addresses to be used for overload translation. Identify the inside interface.

What are two of the required steps to configure port address translation? (choose two)

Show ip nat translations

What command shows all active translations on your router?

Show ip DHCP binding

What command shows that dhcp is operational?

The DHCP server will not issue the addresses ranging from 192.168.24.1 to 192.168.24.5.

What will be the result of adding the command ip dhcp excluded-address 192.168.24.1 192.168.24.5 to the configuration of a local router that has been configured as a DHCP server?

Inside Global

Which label describes the address of the source as seen from outside the network?

During the autoconfiguration process, a router advertises the IPv6 64-bit prefix of its interface, and the host prepends this prefix to its EUI-64 formatted MAC address.

Which of the following statements are true in regards to using SLAAC?

IP DHCP excluded-address 192.168.100.1 192.168.100.10 IP DHCP excluded-address 192.168.101.254 IP DHCP pool LAN-POOL-100 network 192.168.100.0 255.255.254.0 default-router 192.168.100.1

Which set of commands will configure a router as a DHCP server that will assign IPv4 addresses to the 192.168.100.0/23 LAN while reserving the first 10 and the last addresses for static assignment?

Static NAT features cannot be combined with the NAT Overload features.

You are troubleshooting a NAT configuration on your router. It seems that all of the syntax is in place, but users are not able to access the internet. You are able to ping internet websites from your router successfully. What is the most likely cause of the problem? interface fastethernet 0 ip address 192.168.1.1 255.255.255.0 interface fastethernet 1 ip address dhcp ip nat outside ip route 0.0.0.0 0.0.0.0 fastethernet 1 access-list 50 permit 192.168.1.0 0.0.0.255 ip nat inside source static tcp 192.168.1.50 80 interface fastethernet 1 80 ip nat inside source list 50 interface fastethernet 1 overload

A NAT pool named Ranken that defines the starting and ending public IP addresses.

You configure the border router with the command R1(config)# ip nat inside source list 7 pool Ranken. What is required to be configured in order for this particular command to work?
