请参阅展览。在标准ACL中将使用哪个命令,以仅允许连接到R2 G0 / 0接口的网络上的设备访问连接到R1的网络?[img=496x273]17e0b960a8a0e54.png[/img]
A: access-list 1 permit 192.168.10.0 0.0.0.63
B: access-list 1 permit192.168.10.0 0.0.0.255
C: access-list 1 permit192.168.10.128 0.0.0.63
D: access-list 1 permit192.168.10.96 0.0.0.31
A: access-list 1 permit 192.168.10.0 0.0.0.63
B: access-list 1 permit192.168.10.0 0.0.0.255
C: access-list 1 permit192.168.10.128 0.0.0.63
D: access-list 1 permit192.168.10.96 0.0.0.31
举一反三
- 请参见图示。在标准ACL中,哪一命令将用于仅允许连接至R2G0/0接口的网络上设备访问连接至R1的网络?() A: access-list 1 permit 192.168.10.128 0.0.0.63 B: access-list 1 permit 192.168.10.96 0.0.0.31 C: access-list 1 permit 192.168.10.0 0.0.0.255 D: access-list 1 permit 192.168.10.0 0.0.0.63
- 网络管理员是Cisco路由器上配置访问控制列表,允许来自只的网络192.168.146.0,192.168.147.0,192.168.148.0和192.168.149.0主机。哪个结合是最好的完成任务,当两个ACL语句?() A: access-list 10 permit ip 192.168.147.0 0.0.0.255.255 B: access-list 10 permit ip 192.168.149.0 0.0.0.255.255 C: access-list 10 permit ip 192.168.146.0 0.0.0.0.255 D: access-list 10 permit ip 192.168.146.0 0.0.0.1.255 E: access-list 10 permit ip 192.168.148.0 0.0.0.1.255 F: access-list 10 permit ip 192.168.146.0 255.255.255.0
- 配置如下两条ACL:Access-list 1 permit 10.110.10.1 0.0.255.255, Access-list 2 permit 10.110.100.100 0.0.255.255,ACL1和2,所控制的地址范围关系是?
- 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
- 网络管理员需要配置标准 ACL,使得只有 IP 地址为 192.168.15.23 的管理员工作站能够访问主要路由器的虚拟终端。哪两个配置命令可以完成该任务?(选择两项) A: Router1(config) B: access-list 10 permit 192.168.15.23 0.0.0.0 C: Router1(config) D: access-list 10 permit 192.168.15.23 0.0.0.255 E: Router1(config) F: access-list 10 permit 192.168.15.23 255.255.255.0 G: Router1(config) H: access-list 10 permit 192.168.15.23 255.255.255.255 I: Router1(config) J: access-list 10 permit host 192.168.15.23
