Question 8 of 20

9. A company needs to build a large Layer 3 WLAN to cover its office building. There are a large number of employees in the office building and they usually connect to the company WLAN at the entrance and then move to their own work locations.
The company has deployed a wired network and developed a mature wired network management mechanism. The company requires that the newly deployed WLAN be managed and maintained uniformly with the wired network. The IP address of the AC is 172.168.11.1.
Which of the following operations performed by network engineers are CORRECT during WLAN planning? (Multiple Choice)

To facilitate unified wired and wireless network management, adopt the "Chassis switch+ACU2" architecture and configure wired and wireless convergence.

Because the company has a large number of employees and they all connect to the WLAN at the office building entrance, configure VLAN Pool to address the challenge of too many IP address requests in certain areas.

On a large WLAN, an AC manages many APs. To facilitate unified management and maintenance, add APs connected to the AC to the same AP group.

On a Layer 3 WLAN, set the Option 43 field to 030B3137322E3136382E31312E31 on the Windows 2003 DHCP server.

Question 9 of 20

10. Which statements about reliability measurement are TRUE? (Multiple Choice)

Generally, system reliability is determined by mean time between failure (MTBF) and mean time to repair (MTTR).

MTBF refers to the average time (usually expressed in hours) from the fault occurrence time to the fault recovery time. A larger MTBF indicates a higher reliability.

MTTR refers to the average time from the fault occurrence time to the fault recovery time.

The formula for calculating the MTTR is as follows: MTTR= Fault detection time + Hardware replacement time + System initialization time + Link recovery time + Route convergence time + Forwarding recovery time A smaller MTTR indicates a higher reliability.

Question 10 of 20

11. A company has deployed a W1.AN, and all APs are transmitting WLAN services. The company needs to upgrade AP versions.
Which of the following upgrade methods is recommended to minimize the impact on user services?

Automatic AP upgrade

In-service AP upgrade

AP upgrade through the web system

AP upgrade in Boot mode

To limit the total duration for the user connection.

To specify the point of time at which user access is allowed.

To specify the point of time before which the user must disconnect from the network.

To specify the time period in which user access is allowed.

802.1x is a technological system, in which RADIUS is included.

802.1x and RADIUS are different technologies, but they are often used together for user access control.

802.1x and RADIUS are different and are not used together.

Question 15 of 20

TRUE

FALSE

Question 16 of 20

17. The following is the URL template configuration for the connection between the AC6005 and Portal server.
Which statement is FALSE about the URL template configuration?
url-template name huawei
url http://10.254.1.100:8080/portal
url-parameter ssid ssid

The port number 8080 can be changed to 8443.

The word "portaI" can be changed to "webauth".

The url-para meter ssid ssid command sets the SSID to ssid.

The url-para meter ssid ssid command indicates that the SSID can be any SSID.

Question 17 of 20

18. On a WLAN that uses the AC6005 as the RADIUS client, which of the following statements is TRUE about the authentication-free rule profile?

The authentication-free rule profile is used to permit the IP addresses of anti-virus devices such as the anti-virus gateway and firewall.

The authentication-free rule profile is used to permit the IP addresses of the DNS, DHCP, and authentication servers.

The authentication-free rule profile can use advanced ACLs.

The authentication-free rule profile can permit specified IP addresses only by using ACLs.

Question 18 of 20

19. Which statement about linear networking of a Mesh network is FALSE?

The neighbor can be manually specified.

The neighbor cannot be manually specified.

802.11s packets converted from 802.3 packets can be transmitted over the links between MPs and then transmitted over wireless links.

Single-point failures may occur.

Question 19 of 20

20. To shorten the STA roaming time, the APs perform 4-way handshake using WPA and WPA2 to negotiate keys.
In this way, negotiation packets are not forwarded to the AC, reducing the time required.

TRUE

FALSE
