举一反三
- 你需要创建一个标准访问控制列表用来拒绝主机172.16.198.94/19所在的子网,表示错误的有()。 A: access-list10deny172.16.192.00.0.31.255 B: access-list10deny172.16.0.00.0.255.255 C: access-list10deny172.16.172.00.0.31.255 D: access-list10deny172.16.188.00.0.15.255 E: access-list10deny172.16.192.00.0.15.255
- 创建一个标准访问控制列表用来拒绝网络192.168.160.0到192.168.191.0内的主机,下面表达式正确的是()。 A: Aaccess-list 10 deny 192.168.160.0 255.255.240.0 B: Baccess-list 10 deny 192.168.160.0 0.0.191.255 C: Caccess-list 10 deny 192.168.160.0 0.0.31.255 D: Daccess-list 10 deny 192.168.0.0 0.0.31.255
- 你需要创建一个标准命名访问控制列表cisco用来拒绝主机172.16.198.94/19所在的子网,表示错误的有()。 A: Aip access-list standard cisco deny 172.16.192.0 0.0.31.255 B: Bip access-list standard cisco deny 172.16.0.0 0.0.255.255 C: Cip access-list standard cisco deny 172.16.172.0 0.0.31.255 D: Dip access-list standard cisco deny 172.16.188.0 0.0.15.255 E: Eip access-list standard cisco deny 172.16.192.0 0.0.15.255
- An inbound access list has been configured on a serial interface to deny packet entry for TCP and UDP ports 21, 23 and 25. What types of packets will be permitted by this ACL (Choose three.)()。
- 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)
