AC+License-free access

Fit AP management for small and medium-sized branches/stores

Q165. SD-WAN’s multiple transmission and selective reception function only supports wired link MPLS/internet mode, and does not support 4G/5G mode.

Correct

Error

Q166. In the Wi-Fi 6 protocol, both OFDMA and WU-MINO can improve the multi-user concurrent experience in high-density scenarios. OFDMA is more suitable for large packet transmission scenarios, while MU-WIMO is more suitable for small packet transmission scenarios.

Correct

Error

Q167. The relationship between WLAN signal transmission distance and attenuation value is: every time the transmission distance doubles, the signal attenuates by about 10dB.

Correct

Error

Q168. In Huawei’s SD-WAN solution, iMasterNCE establishes a management channel with CPE devices through the Restful protocol.

Correct

Error

Q169. In the current single ACCAPWAP disconnected wireless service retention solution, PSK new user access can be supported.

Correct

Error

Q170. In CloudCampus, tenants can only be managed by MSP administrators.

Correct

Error

Q171. In a WLAN outdoor wireless coverage scenario, using external antennas for coverage, the throughput of wireless terminals remains low. What are the possible reasons for this result? Multiple choice

The test terminal does not support 802.11n/ac

Traffic speed limit configuration

RSSI is too low, link establishment speed is slow

Interference causes throughput to decrease

Q172. DHCP is the most commonly used method for deployment in SD-WAN scenarios, followed by USB drive deployment.

Correct

Error

Q173. In the CloudCampus Huawei public cloud deployment scenario, what are the possible reasons for CloudBox registration failure?

The device is not joined to the site.

Device registration configuration error.

The device is not included in the license package.

The device failed to automatically obtain an IP address.

Q174. In the CloudCampus public cloud deployment scenario, tenants log in to the CloudCampus cloud management platform through the Internet and connect to the cloud management platform via HTTPS to ensure that tenants and MSPs access the management platform in a secure manner.

Correct

Error

Q175. Which RR deployment methods does Huawei SD-WAN solution support?

RR multi-region deployment

RR and site co-deployment

RR independent deployment

Q176. In a WLAN network environment, wireless client access can be controlled by selectively selecting blacklists and whitelists. Which of the following statements about blacklists and whitelists is incorrect?

Use the whitelist function. If the whitelist is not empty, only STAs matching the whitelist can go online, and other STAs cannot go online.

Use the blacklist function. If the blacklist is empty, any STA is allowed to go online.

Use the blacklist function. If the blacklist is not empty, STAs matching the blacklist cannot go online, while other STAs can go online.

Use the whitelist function. If the whitelist is empty, no STA will be allowed to go online.

Q177. Huawei’s WLAN focus on the IOT (Internet of Things) sector: Building a pipeline-based technology platform and ecosystem, leveraging partners’ expertise in the IOT field, achieving multi-network convergence, and maximizing customer benefits. Which of the following are its advantages?

AP provides site and communication channels

iMasterNCE unified management of IoT cards

Solved site design and power supply issues

Wi-Fi and IOT multi-network integration

Q178. The wireless frequency band used by WLAN is

5.8GHz and 8GHz

2.4Hz and 5GHZ

400MHz and 800MHZ

800MHz and 1800MHZ

Q179. Each AC must be assigned a unique IP address. The APs attached to the AC device learn this IP address or the IP address configured on this interface for communication between the AC and AP in the ACHIT AP network and for establishing CAPWAP tunnels.

Correct

Error

Q180. Which of the following statements about NAC technology is correct?

802.1X authentication does not require high-level client software on user terminals and offers flexible deployment.

802.1X authentication is suitable for scenarios where new networks are built, users are concentrated, and information security requirements are strict.

Generally, MAC address authentication requires manual registration of MAC addresses, which is complex to manage.

Portal authentication is suitable for scenarios with dispersed users and high user mobility, such as visitor authentication.

Q181. If an AC has only one interface connected to an aggregation switch, and user traffic flows directly through the aggregation switch to the public network without passing through the AC, which networking mode should be used?

Direct connection mode + tunnel forwarding

Side-by-side mode + direct forwarding

Side-by-side mode + tunnel forwarding

Direct connection mode + direct forwarding

Q182. Which of the following descriptions of the WLAN traffic forwarding model is correct?

In Layer 3 roaming with tunnel forwarding, after traffic returns to the HAC, it also needs to return to the HAP and then be forwarded to the upper-layer network.

By default, in direct forwarding Layer 3 roaming, when traffic returns to the HAC, it is forwarded directly to the upper-layer network.

For Layer 2 roaming with direct forwarding and tunnel forwarding, the traffic path remains the same after roaming and will be forwarded back to the home agent through the CAPWAP tunnel.

Direct forwarding Layer 2 roaming: After roaming, traffic will be forwarded directly on the FAP without going through the FAC.
