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
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
举一反三
- 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
- 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?
- 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
- 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
- 智慧职教: 考虑通过 access-class in 命令应用至路由器的 ACL 的如下输出。网络管理员从所显示的输出能够得出什么结论? R1# Standard IP access list 2 10 permit 192.168.10.0, wildcard bits 0.0.0.255 (2 matches) 20 deny any (1 match)
