Huawei H12-351_V1.0 Exam Questions Instant Access

Question 1

In a dual-link HSB scenario, after an AP sets up CAPWAP links with the active and standby WACs, which of the following types of packets does the AP periodically send to the WACs to detect link status?

ADTLS

BJoin

CEcho

DKeepalive

Answer : C

In a dual-link HSB scenario, after an AP sets up CAPWAP links with the active and standby WACs, the AP periodically sends Echo packets to the WACs to detect link status. The Echo packets are sent every 30 seconds by default.

Question 2

Which of the following statements are true about the WLAN site survey In different typical scenarios? (Select All that Apply)

AIn a classroom scenario. If the walls are made of reinforced concrete, the signal attenuation Is high. In this case, you are advised to test the attenuation during the site survey. Additionally, pay attention to the locations of ELV rooms in the teaching building.

BIn an office scenario, the load-bearing columns and partitions affect the signal coverage. If an integrated ceiling is used, deploy APs near maintenance entrances. If a metal ceiling is used, mount APs on the ceiling or wall.

CIn a ward-round scenario, high requirements are posed on the coverage field strength, roaming effect, and bandwidth. Determine the interference of medical equipment and the areas where Wi-Fi signals are not allowed.

DIn a stadium scenario, the onsite environment is complex and cabling is difficult. Therefore, confirm with the property management company about ELV rooms and cabling. If the transmission distance is too long, consider deploying more switches. During the survey, focus on the interference between APs and AP mounting modes.

Answer : A, B, C, D

Only: All statements are true about the WLAN site survey in different typical scenarios.

Question 3

Which of the following user access authentication modes are supported In Huawel's CloudCampus Solution? (Select All that Apply)

A802. IX authentication

BMAC address authentication

CPortal authentication

Answer : A, B, C

Huawei's CloudCampus Solution supports three user access authentication modes: 802.1X authentication, MAC address authentication, and Portal authentication.

Question 4

Which of the following statements about the home agent are true? (Select All that Apply)

AThe home agent communicates with the gateway on the STAs1 home network at Layer 2.

BThe home agent communicates with the gateway on the STAs' home network at Layer 3.

CA home AP can function as a home agent of STAs.

DA home WAC can function as a home agent of STAs.

Answer : B, D

The home agent is a device that communicates with the gateway on the STAs' home network at Layer 3 and maintains the binding entries of STAs' home addresses and care-of addresses. A home WAC can function as a home agent of STAs, while a home AP cannot.

Question 5

The display sync-configuration compare command is executed on the backup WAC in HSB to check wireless configuration synchronization. Based on the command output, which of the following statements are true? (Select All that apply)

AThis command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization.

BThe configuration of ssid-profile 2 exists on both the master and backup WACs.

CThe configuration of vap-profile name 3 exists on the master WAC but not on the backup WAC.

DThe configuration of vap-profile name 2 exists on the backup WAC but not on the master WAC.

Answer : A, C

The display sync-configuration compare command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization. The command output shows the differences between the configurations on the master and backup WACs. In this case, the configuration of vap-profile name 3 exists on the master WAC but not on the backup WAC.

Question 6

In Huawei's smart roaming solution, which of the following methods can be used by a WAC to discover and maintain neighboring AP entries of STAs? (Select All that Apply)

AThe WAC obtains such entries using 802. 11v.

BThe AP listens to the Probe frames sent by STAs.

CThe AP periodically and proactively scans neighboring APs of STAs.

DSTAs proactively report neighboring AP information.

Answer : B, C

In Huawei's smart roaming solution, the WAC can discover and maintain neighboring AP entries of STAs by using two methods: passive listening and active scanning. Passive listening means that the AP listens to the Probe frames sent by STAs and reports them to the WAC. Active scanning means that the AP periodically and proactively scans neighboring APs of STAs and reports them to the WAC.

Question 7

To which of the following scenarios is radio calibration applicable?

AEnterprise office scenario

BRail transportation scenario

CHigh-density scenario

DWDS or mesh backhaul scenario

Answer : C

Radio calibration is applicable to high-density scenarios where a large number of users access the network simultaneously and require high bandwidth, such as stadiums, exhibition halls, and conference centers. Radio calibration can improve user experience by increasing the frequency bandwidth for high-load APs.
