Question 6 of 435
Trunk interfaces can send both tagged and untagged frames.
Answer

Suggested Answer

The suggested answer is A.

Trunk interfaces, commonly used in VLAN setups, are designed to handle both tagged and untagged frames. Tagged frames contain VLAN information as they pass through various network segments, while untagged frames are typically part of the native VLAN for the trunk port. This dual capability allows trunk interfaces to facilitate seamless communication across different VLANs.

Question 8 of 435
Which of the following protocols can be used to prevent loops on a Layer 2 network with redundant links?
Answer

Suggested Answer

The suggested answer is B.

The Spanning Tree Protocol (STP) is specifically designed to prevent network loops by creating a loop-free logical topology for Ethernet networks. It achieves this by blocking redundant paths that could potentially cause broadcast storms and network instability. STP constantly monitors the network to ensure that only the most optimum path is active, while redundant links are placed in a standby state to be activated if the active path fails.

Question 9 of 435
According to the VTY user interface configuration shown in the following figure, the user level is set to 3.
[Huawei]user-interface vty 0 14
[Huawei-ui-vty0-14]acl 2000 inbound
[Huawei-ui-vty0-14]user privilege level 3
[Huawei-ui-vty0-14]authentication-node password
Please configure the login password (maximum length 16):huawei
Answer

Suggested Answer

The suggested answer is A.

The user privilege level in the configuration is explicitly set to 3 by the command user privilege level 3. This means that login users on the VTY user interface will have a user level of 3. The user level can range from 0 to 15, with higher values indicating higher privilege levels. Therefore, it is true that the user level is set to 3 as per the given configuration.

Question 10 of 435
Which of the following packets are OSPF packets?
Answer

Suggested Answer

The suggested answer is A, B, C.

OSPF, which stands for Open Shortest Path First, is a routing protocol that uses several types of packets to establish and maintain router information. The primary OSPF packet types include HELLO, which is used to identify and maintain neighbor relationships; LSR (Link-State Request), which is used to request additional information about link-state advertisements (LSAs); and LSU (Link-State Update), which is used to provide updated link-state information. Although LSA (Link-State Advertisement) is an important concept in OSPF, it is not classified as an OSPF packet itself, but rather, it is the data conveyed within other OSPF packets like LSU.
