The same ACL can be called under multiple interfaces

ACL can match the TCP/UDP port number of the packet, and can specify the range of port numbers

The same ACL can be called under multiple interfaces

When ACL defines rules, it can only proceed in the order of 10, 20, 30

ACL cannot be used to filter OSPF traffic, because OSPF traffic does not use UDP protocol encapsulation

When calling ACL under the interface, it can only be applied to the outbound direction

Refer to the graphic, which of the following statements is true about OSPF topology and configuration?

After the default network type of the interface on R1 is restored to broadcast and the hello packet sending interval is changed to 10s, a stable OSPF neighbor relationship can be set up between R1 and R2.

Compared with R1, R2 is more likely to become the DR because the DR priority of the interface on R2 is lower than that of R1.

After the default network type of the interface on R1 is restored to broadcast, a stable OSPF neighbor relationship can be set up between R1 and R2.

After the default network type of the interface on R1 is restored to broadcast and the hello packet sending interval is changed to 10s, a stable OSPF neighbor relationship can be set up between R1 and R2.

A stable OSPF neighbor relationship can be set up between R1 and R2.

Pre: indicates the preference value of a routing protocol.

NextHop: indicates the address of the local interface corresponding to a route.

Proto: indicates the source of a route.

Destination/Mask: indicates the address and mask length of the destination network or host.

Which of the following statements about the output on the router R1 shown in the figure is false?

The physical link of Ethernet 0/0/0 is working normally.

The broadcast address of Ethernet 0/0/0 is 10.0.12.255.

Which of the following statements about static routes on Huawei devices is false?

The cost of a static route cannot be changed.

The default preference value of a static route is 60.

When the preference value of a static route is 0, this static route is selected as the optimal route.

The cost of a static route cannot be changed.

The preference value of a static route is in the range 1 to 255.

Which of the following statements are true about the dynamic MAC address table?

Dynamic MAC address entries are obtained by learning the source MAC addresses of packets received by an interface and can be aged out.

After a device is reset, an interface card is hot-swapped, or an interface card is reset, dynamic MAC address entries on the device or interface card are lost.

You can obtain the number of users communicating on an interface by checking the number of specified dynamic MAC address entries.

Dynamic MAC address entries are obtained by learning the source MAC addresses of packets received by an interface and can be aged out.

After a device is reset, an interface card is hot-swapped, or an interface card is reset, dynamic MAC address entries on the device or interface card are lost.

You can obtain the number of users communicating on an interface by checking the number of specified dynamic MAC address entries.

After a device is reset, an interface card is hot-swapped, or an interface card is reset, the saved entries on the device or interface card are not lost.

On the network shown in the figure, router A adopts link aggregation in manual load balancing mode, and G0/0/1 and G0/0/2 are added to link aggregation group (LAG) 1. Which of the following statements is false about Eth-Trunk 1 on router A?
