The client router’s interface GigabitEthernet0 / 0 is connected to the LAN host HostA , and its IP address is 192.168.0.2/24 ;

The client router’s interface GigabitEthernet0 / 0 is connected to the LAN host HostA , and its IP address is 192.168.0.2/24 ;

Interface Serial6 / 0 interface is connected to the far end and is currently operating normally. The ACL configuration is now added as follows:

firewall enable

firewall default permit

acl number 3003

rule 0 permit tcp

rule 5 permit icmp

acl number 2003

rule 0 deny source 192.168.0.0 0.0.0.255

interface GigabitEthernet0/0

firewall packet-filter 3003 inbound

firewall packet-filter 2003 outbound

ip address 192.168.0.1 255.255.255.0

interface Serial6/0

link-protocol ppp

ip address 6.6.6.2 255.255.255.0

Assuming that other related configurations are correct, then ______ . (Multiple choices)
A . HostA cannot ping the two interface addresses on the router
B . HostA can not ping through 6.6.6.2 , but can ping through 192.168.0.1
C . HostA can not ping through 192.168.0.1 , but can ping through 6.6.6.2
D . HostA can Telnet to the router

Answer:   CD

Explanation:

In fact, ACL is only limited by 2003 3003 , tcp icmp is allowed, meaningless by default

Note: the source address is rejected out 192.168.0.0/24 all packets, including icmp the echo , echo-Reply , etc. used in the G0 / 0 interface outbound direction, when Aping the gateway, the gateway returns icmp echo reply packets are deny If the G0 / 0 inbound direction, a of ping gateway, transmitted icmp echo packets are deny Ping 6.6.6.2 Similarly
