The administrator can use the ACL rule 'time-range am9topm5 08:00 to 17:00 off-day' to block Internet access to all hosts between 8:00-17:00 every day.
False
In the network shown in the figure below, which interface does the MAC address of host B correspond to in the MAC address table of switch A?
Eth-Trunk 1

The user authority level is set to level 3 in the given vty configuration.
True
Match the following ACL rules with their corresponding effects:
rule 5 deny source 200.0.12.0.0.0.7 = Deny access to the host with source IP address 200.0.12.7 rule 10 permit source 200.0.12.0.0.0.15 = Permit access to the host with source IP address 200.0.12.15 interface GigabitEthernet0/0/1 traffic-filter outbound acl 2000 = Apply ACL 2000 to the outbound traffic on interface GigabitEthernet0/0/1
What is the maximum length of the login password in the given vty configuration?

Study Notes
Trunk Port Data Frame Handling
- When the VLAN ID is the same as the PVID of the port and is a VLAN ID allowed by the port, remove the tag and send the message.
- If the VLAN ID is different from the PVID of the port, the data frame is dropped.
VLAN ID in IEEE802.1Q
- The VLAN ID in the VLAN format defined by IEEE802.1Q has 12 bits.
MAC Address Table in Switch A
- In the MAC address table of switch A, the MAC address of host B corresponds to the Eth-Trunk 1 interface.
Root-Bridge Switch
- All ports on the root-bridge switch are designated ports.
Bridge ID in Configuration BPDU
- The bridge ID that is unlikely to appear in the configuration BPDU sent by the switch is 2048 00-01-02-03-04-CC.
VLAN Creation
- The command "vlan batch 10 20" creates 2 VLANs.
- The command "vlan batch 10 to 20" creates 11 VLANs.
Root Path Cost in STP
- By default, the root path cost of the root bridge in the STP protocol must be 0.
ACL Rule for Internet Access
- To restrict hosts from accessing the Internet between 8:00-17:00 every day, the ACL rule needs to be bound to the traffic-filter outbound in the GO/0/1 interface allocation.
Time-Range ACL Rule
- The correct time-range ACL rule is: time-range am9topm5 08:00 to 17:00 daily acl number 2001 rule 5 deny time-range am9topm5
Wrong Statement in ACL Rule
- The wrong statement is that the host whose source IP address is 200.0.12.8 cannot access the Internet.
AAA Authentication
- On Huawei equipment, if you use AAA authentication for authorization, when the remote server does not respond, you can authorize from the network equipment side.
DHCP Client Lease Renewal
- The DHCP client expects to send the lease renewal message for the first time at 50% of the lease time.
Reasons for Interface IP Address Allocation Failure
- Possible reasons for interface IP address allocation failure after logging in to the router through Telnet include incorrect configuration of the Telnet user level.
VTY Configuration
- The user authority level is set to level 3 in the VTY configuration, and the login password is set to "huawei".
