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
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
举一反三
- 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?(请选择两项。) A: Router1(config) B: access-list 10 permit 192.168.15.23 255.255.255.255 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 0.0.0.0 G: Router1(config) H: access-list 10 permit host 192.168.15.23
- 对于以下ACL语句描述正确的是( ) router(config)#ip access-list standard TELNET router(config-std-nacl)#permit 192.168.4.2 0.0.0.0 router(config)#line vty 0 4 router(config-line)#access-class TELNET in
- 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
- 路由器命令“Router(config)#access-list 1 permit192.168.1.1”的含义是()。
- 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
