If you configured this correctly as shown in Example 4-33, you have scored 4 points. The DHCP feature is very useful and many companies use it. Here you have a concept of a host that stores the DHCP bindings. Notice which commands in Example 4-33 are relevant to accomplish this task. Example 4-33. R6 DHCP ConfigurationR6#show run | b dhcp ip dhcp database ftp://user:password@160.10.22.253/router-dhcp write-delay 240 ip dhcp excluded-address 160.10.22.3 160.10.22.6 ! ip dhcp pool VLAN_22 network 160.10.22.0 255.255.255.0 dns-server 160.10.22.100 160.10.22.101 default-router 160.10.22.3 160.10.22.5 domain-name mycompany.com lease 7
If you configured this correctly as shown in Example 4-34, you have scored 2 points. The ip redirects command allows the interface to redirect incoming packets to a better path. Disabling the feature with no ip redirects forces the interfaces to accept the packet and to not redirect it. Example 4-34. R5 Disabling the ICMP Redirect FeatureR1#show run int e0/1 Building configuration... Current configuration : 97 bytes ! interface Ethernet0/1 ip address 160.10.25.1 255.255.255.0 no ip redirects half-duplex end R1# ! ! ________________________________________________________________ R5#show run int fa0/1 Building configuration... Current configuration : 113 bytes ! interface FastEthernet0/1 ip address 160.10.25.5 255.255.255.0 no ip redirects duplex auto speed auto end R5#
If you configured this correctly as shown in Example 4-35, you have scored 2 points. In Example 4-35, you have the necessary configuration to accomplish this task. Notice that the requirement to use "passive mode" will not require any configuration, because it is the default mode and will not show in your configuration. Example 4-35. R4 Configuration to Get via FTP a Core DumpR4#show run Building configuration... Current configuration : 97 bytes ! ! ip ftp source-interface Ethernet0/0 ip ftp username CISCO ip ftp password CCIE ! ! exception protocol ftp exception dump 140.200.10.200 exception core-file dumpfile ! R4#
If you configured this correctly as shown in Example 4-36, you have scored 2 points. Example 4-36. R2 Disabling BOOTP Services ConfigurationR2#show run | i bootp no ip bootp server R2# |
