C: access-list 121 permit host 172.16.1.3
D: access-list 131 permit tcp any 172.16.1.3 0.0.0.0 eq 69
举一反三
- 下列命令中，正确的是 A: access-list 101 permit ip 172.16.1.3 0.0.0.0 any eq 23 B: access-list 111 deny ftp 172.16.1.3 0.0.0.0 any eq 21 C: access-list 121 permit host 172.16.1.3 any D: access-list 131 deny udp 172.16.1.3 0.0.0.0 any eq 53
- 下列命令中，正确的是： A: access-list 1 deny ip 172.16.1.3 0.0.0.0 B: access-list 101 deny ip 172.16.1.3 0.0.0.0 C: access-list 1 deny host 172.16.1.3 D: access-list 101 deny 172.16.1.3 0.0.0.0
- 仅仅允许到主机1.1.1.1的SMTP邮件服务的命令是（）。 A: access-list 10 permit smtp host 1.1.1.1 B: access-list 110 permit ip smtp host 1.1.1.1 C: access-list 10 permit tcp any host 1.1.1.1 eq smtp D: access-list 110 permit tcp any host 1.1.1.1 eq smt
- 以下ACL语句中，含义为“允许172.168.0.0/24网络所有PC访问10.1.0.10中的FTP服务”的是______。 A: access-list 101 deny tcp 172.168.0.0 0.0.0.255 host 10．1．0．10 eq ftp B: access-list 101 permit tcp 172.168.0.0 0.0.0.255 host 10．1．0．10 eq ftp C: access-list 101 deny tcp host 10.1.0.10 172.168.0.0 0.0.0.255 eq ftp D: access-list 101 permit tcp host 10.1.0.10 172.168.0.0 0.0.0.255 eq ftp
- 对于以下ACL语句描述正确的是（ ） (config)#access-list 101 deny icmp any 192.168.10.0 0.0.0.255 echo (config)#access-list 101 permit ip any any (config)#int f0/1 (config-if)#ip access-group 101 in
