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)

1.2 List six access technologies. Classify each one as home access, enterprise access, or wide-area wireless access.

代码如下 #函数定义 def chanageList(list): list.append(" end") print("list",list) #调用 strs =['1','2'] chanageList() print("strs",strs) 下面对 strs 和 list 的值输出正确的是 A: strs ['1','2'] list ['1','2'] B: strs ['1','2','end'] list ['1','2','end'] C: list ['1','2','end'] strs ['1','2','end'] D: list ['1','2','end'] strs ['1','2']

1802cdfa0c72530.png图中第一个列表的创建语句是（ ）。 A: L = list(range(2, 100, 2)) B: L = list(range(2, 101, 2)) C: L = list(range(1, 100, 2)) D: L = list(range(1, 101, 2))

函数如下 defchanageList(list): list.append("end") print("list",list) #调用 strs=['1','2'] chanageList(strs) print("strs",strs) 下面对strs和list的值输出正确的是()。 A: strs list B: strs['1','2'] list['1','2'] C: list['1','2',’end’] strs['1','2',’end’] D: 运行运行有错误

18 A: Deny them access to any food. B: Keep doors and windows shut. C: Destroy their colonies close by. D: Refrain from eating sugary food.

下面对 strs 和 list 的值输出正确的是 A: strs ['1','2'] B: list ['1','2'] C: list ['1','2',’end’] D: strs ['1','2',’end’]

华为交换机配置中，设置端口模式为access并将端口加入vlan 2中的配置命令是（ ）。 A: switchport access vlan 2 switchport mode access B: port link-type access port default vlan 2 C: port link-type access port default pvid vlan 2 D: port link-type access port trunk allow-pass vlan 2

下列选项中,不能创建列表的语句是。 A: list=(1,2,3) B: list=[2] C: list=[1,2,3] D: list=[1,"mathmatics",98]
