NEW QUESTION 167
Routers rely on hardware BFD and FR technology to achieve high reliability. FRR includes LDPFRR and VPNFR. LDPFRR is tunnel-level protection, while VPN FRR is service-level protection.

Correct

Error

NEW QUESTION 168
Among the following authentication methods, which one must the terminal obtain an IP address before authentication?

MAC address bypass authentication

MAC address authentication

802.1X authentication

Portal Authentication

NEW QUESTION 169
Since the receiving sensitivity of the terminal is lower than that of the AP, considering the uplink and downlink balance, setting the AP’s transmit power slightly higher than the terminal can optimize the communication effect.

Correct

Error

NEW QUESTION 170
In Huawei’s SD-WAN solution, the main function of RR (route reflector) is to be responsible for VPN routing and tunnel information publishing between CPEs based on VPN topology strategy.

Correct

Error

NEW QUESTION 171

Tenant Administrator

0perator

Monitor

Auditor

NEW QUESTION 172
What types of application identification technologies are included in Huawei’s SDWAN solution?

Complex Application SA Signature Library Identification

Custom application identification

SAAS first packet identification

NEW QUESTION 173
In the Wi-Fi 6 protocol, both OFDMA and MU-MIMO can improve the multi-user concurrent experience in high-density scenarios. Among them, MU-MIMO is more sensitive to the motion state of the terminal, and the movement of the terminal will cause the gain effect to drop rapidly.

Correct

Error

NEW QUESTION 174
Directional antennas have strong signal gain within their horizontal and vertical lobes, but no signal is detected outside of these lobes. Therefore, it is recommended to use high-gain directional antennas to increase the coverage distance of outdoor APs.

Correct

Error

Correct

Error

NEW QUESTION 177
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.
