Question 2

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

Accepted Answer

When a device is reset, an interface card is hot swapped, or an interface card is reset, the saved MAC address entries are typically lost because they are stored in volatile memory.

Question 5

On a broadcast network with four routers, all the routers run OSPFv3, and the DR priorities of all the routers are not 0. How many adjacencies are there on the network?

Accepted Answer

The answer of On a broadcast network with four routers,...

Question 6

What is the neighbor state when an OSPFv3 adjacency is established?

Accepted Answer

Question 7

Users in the network discovered that the efficiency of a file transfer is low. The administrator used wireshark to observe the network and discovered many duplicate frames. Which statement correctly explains the reason for this?

Accepted Answer

The presence of many duplicate frames suggests that there are loops in the network at the link layer, causing frames to be broadcast repeatedly.

Question 8

Which of the following OSPF states can be used to indicate that an adjacency relationship has been established?

Accepted Answer

The "Full" state in OSPF indicates that an adjacency relationship has been fully established between routers, meaning they have exchanged all necessary information.

Question 9

Question 11

Which of the following values of the Length/Type field in an Ethernet data frame indicates the PPPoE discovery stage?

Accepted Answer

The value 0×8863 in the Length/Type field of an Ethernet frame indicates the PPPoE (Point-to-Point Protocol over Ethernet) discovery stage.

Question 12

Which of the following fields is not included in the OSPF Hello packet?

Accepted Answer

Accepted Answer

In the VRP system, files can be deleted using the delete or unreserved vrpcfg.zip command without needing to clear a recycle bin.

Question 14

In RSTP mode, both alternate and backup ports cannot forward user traffic but can receive, process, and send BPDU.

Accepted Answer

In RSTP (Rapid Spanning Tree Protocol), alternate and backup ports are in a discarding state, meaning they do not forward user traffic but can handle BPDUs (Bridge Protocol Data Units) for network topology changes.

Question 15

Before forwarding IPv6 packets, routers do not need to re-encapsulate the data link layer.

Accepted Answer

The answer of Before forwarding IPv6 packets, routers do not...

Question 17

For DHCP, the priority of an interface address pool is higher than that of a global address pool.

Accepted Answer

In DHCP, an interface address pool is specific to a particular interface and takes precedence over a global address pool, which is used as a fallback option when no specific interface pool is available.

Question 18

Which of the following commands can be used to change the device name to huawei?

Accepted Answer

The command "sysname huawei" is used in some network devices to change the system name to "huawei".

Question 19

Which of the following OSPF packets can be used to send LSAs to the peer router?

Accepted Answer

LSU (Link State Update) packets are used in OSPF to send LSAs (Link State Advertisements) to peer routers.

Question 20

According to the VLAN frame format defined in IEEE 802.1Q, how many bits does a VLAN ID contain?

Accepted Answer

The VLAN ID in the IEEE 802.1Q frame format is 12 bits long, allowing for 4096 possible VLANs.
