Question # 21

Which of the following statements are true about network optimization measures?

Loops may occur if Ethernet cables are incorrectly connected to wall plate APs. In this case, loop detection can be enabled on the wired interfaces of APs to automatically block the interfaces once a loop is detected.

It is recommended that the Beacon interval be adjusted based on the number of VAPs. A long interval increases the sleep time of STAs, and a short interval increases the air interface overhead.

It is recommended that multicast packet suppression be enabled when multicast services are planned on the network.

The rate limit for STAs can be set based on customer requirements. In most cases, 10 Mbps bandwidth for uplink and downlink traffic can support common Internet access applications.

Question # 22

When planning a WLAN using the WLAN Planner, which of the following properties can be set for interference sources?

Installation mode

Frequency band and bandwidth

Antenna properties

Mounting height

Channel and power

Question # 23

Which of the following statements are true about wireless configuration synchronization in Huawei ' s WAC backup solutions?

During batch backup of wireless configuration synchronization, public configurations can be performed on the master AC.

Wireless configuration synchronization requires that the models and software versions of all WACs be the same.

In wireless configuration synchronization, the source-ip and nas-ip are not allowed to be configured based on profiles.

Wireless configuration synchronization can be used only with VRRP HSB or dual-link HSB; it cannot be used with dual-link cold backup or N+1 backup.

Question # 24

An engineer configures the following radio calibration commands on a Huawei WAC. Which of the following statements are true about these commands?

The engineer manually configures die dynamic bandwidth selection (DBS) function.

The engineer manually configures the transmit power control (TPC) function.

The engineer manually configures the receive power control (RPC) function.

The engineer manually configures the Dynamic Channel Assignment (DCA) function.

In the default AP group, the DBS function is enabled by default.

In the default AP group, the DCA function is enabled by default.

Question # 25

When Huawei WLAN Planner is used for network planning, which of the following are included in the network planning report?

Equipment quotation

Planned AP positions

Floor simulation diagram

Bill of materials

Question # 26

On a WLAN, if PoE+ + power supply is used, the distance between a PoE switch and an AP can exceed 100 m.

TRUE

FALSE

Question # 27

In an 802.1X authentication system, the client, access device, and authentication server exchange information using the Extensible Authentication Protocol (EAP).

TRUE

FALSE

Question # 28

After built-in Portal authentication is configured on a Huawei WAC. the Portal authentication page can be displayed but Portal authentication cannot be performed. What are the possible causes?

The AP version is outdated.

The data forwarding mode is direct forwarding, and the WAC does not allow packets from service VLANs to pass through.

The route configuration is incorrect. As a result, the STA cannot communicate with the built-in Portal server.

The password entered on the STA is incorrect

Question # 29

Which of the following methods are used in IPsec to ensure secure transmission of service data on the network through encryption and authentication?

The receiver verifies the identity of the sender.

The receiver rejects old or duplicate packets in order to prevent attacks initiated by malicious users who resend sniffed packets,

The sender verifies the identity of the receiver.

Data integrity is verified.

Question # 30

Deploying user authentication points at the access layer achieves fine-grained permission management and high network security. However, as the network scale is rapidly expanding, problems arise, such as heavy configuration workloads and high O & M difficulties. To mitigate these problems, user authentication points can be moved upward from the access layer to the aggregation or core layer. In this way, authentication information across the entire network is centralized and the number of user authentication points is decreased, thereby reducing the configuration and maintenance workload.

TRUE

FALSE
