A.If Ethernet 0/2 goesdown， the standby router will take over
B.The local IP address of Router A is 10.1.0.6
C.When Ethernet 0/3 of RouterA comes back up， the priority will become 105
D.Router A will assume the active state if its priority is the highest
E.The local IP address of Router A is 10.1.0.20

A.Router 172.16.11.111 will be the active router because its HSRP priority is preferred over router172.16.11.112
B.The IP address 172.16.11.112 is the virtual HSRP router IP address
C.The nonpreempt feature is enabled on the 172.16.11.112 router
D.The IP address 172.16.11.111 is the virtual HSRP router IP address
E.Router 172.16.11.112 will be the active router because its HSRP priority is preferred over router172.16.11.111
F.The preempt feature is not enabled on the 172.16.11.111 router

A.The router with IP address 172.16.11.112 is using default HSRP priority
B.The IP address 172.16.11.115 is the virtual HSRP IP address
C.The priority of the router with IP address 172.16.11.112 is preferred over the router with IPaddress 172.16.11.111
D.The router with IP address 172.16.11.111 haspreempt configured
E.The final active router is the router with IP address 172.16.11.111
F.The router with IP address 172.16.11.112 has nonpreempt configured

A.The command standby 1 preempt was added to Catalyst_A
B.Catalyst_A is load sharing traffic in VLAN 50
C.Hosts using the default gateway address of 192.168.1.1 will have their traffic sent to192.168.1.11 even after Catalyst_A becomes available again
D.Hosts using the default gateway address of 192.168.1.2 will have their traffic sent toCatalyst_A

A.Hosts connected to the FastEthernet0/1 interface will not receive DHCP replies from the router
B.The first DHCP client to connect to the FastEthernet 0/1 interface will receive the IP address10.10.0.1
C.The first DHCP client to connect to the FastEthernet 0/0 interface will receive the IP address10.0.0.1
D.DHCP requests received on the FastEthernet 0/1 interface will be forwarded to 10.0.0.2
E.The first DHCP client to connect to the FastEthernet 0/0 interface will receive the IP address10.0.0.6

A.The network shown in the output under the ip dhcp pool Central command should be changedto network 10.10.0.0 with a mask of 255.255.255.0
B.A second DHCP pool for network 10.10.0.0/24 should be configured
C.An ip dhcp excluded-address global configuration command for network 10.10.0.0/24 should beissued
D.The ip helper-address 10.0.0.1 command should be issued so that the address can be added tothe FastEthernet0/0 configuration
E.The ip helper-address 10.0.0.1 command should be issued so that the address can be added tothe FastEthernet0/1 configuration

A.The router will distribute IP addresses from pool 1 until its addresses are exhausted. Then therouter will begin distributing addresses from pool 2
B.The configuration is invalid because the DHCP options are global configuration commands
C.The configuration is incomplete until the DHCP pools are bound to the appropriate interface orinterfaces
D.The router will choose which pool to use based upon the interface the DHCP request wasreceived on

A.Hosts belonging to DHCP pool 1 and pool 2 will retain their IP settings for 30 hours before theymust renew
B.Hosts will receive IP settings from pool 1 until the addresses run out， and then hosts will receivethe settings from pool 2
C.Hosts in the 10.10.20.0/24 subnet will use 10.10.20.50 as its DNS server
D.DHCP pool 0 needs to have the ip dhcp excluded-address command to exclude the defaultrouter and DNS servers
