Refer to the exhibit． Why is flash memory erased prior to upgrading the IOS image from the TFTP server? [*] The router cannot verify that the Cisco IOS image currently in flash is valid Flash memory on Cisco routers can contain only a single IOS image． Erasing current flash content is requested during the copy dialog． In order for the router to use the new image as the default, it must be the only IOS image in flash．

Which two tasks does the Dynamic Host Configuration Protocol perform? Set the IP gateway to be used by the network． Perform host discovery used DHCPDISCOVER message． Configure IP address parameters from DHCP server to a host． Provide an easy management of layer 3 devices． Assign and renew IP address from the default pool．

Refer to the exhibit． For what two reasons has the router loaded its IOS image from the location that is shown?

Refer to the exhibit． What statement is true of the configuration for this network? [*] The configuration that is shown provides inadequate outside address space for translation of the number of inside addresses that are supported． Because of the addressing on interface FastEthernet0/1, the Serial0/0 interface address will not support the NAT configuration as shown． The number 1 referred to in the ip nat inside souce command recerences access-list number 1． ExternalRouter must be configured with static routers to network 172．16．2．0/24

Which statement describes the process of dynamically assigning IP addresses by the DHCP server?
