NO.21 iMaster NCE-Campuslnsight comprehensively analyzes WLAN client access, displays success rates and time consumption of association, ——–, and DHCP. It also provides issue analysis and optimization suggestions.
(Enter lowercase letters.)

NO.22 In a dual-link backup scenario, the active/standby link switchover mode is set to priority. When the active link recovers, the AP detects that the original active link has a higher priority and triggers a switchback. How many Echo intervals does the AP wait for before switching back to the original primary WAC?

NO.23 Which of the following parameters can be allocated to clients In DHCPv6 stateful autoconflguratlon? (Select All that Apply)

IPv6 address

PD prefix

SNTP server address

DNS server address

NO.24 Which of the following statements about WLAN roaming and signal strength Is false?

Smart roaming can be enabled on the WAC to help ST As roam and associate with APs with better signals.

Generally, a STA roams when it detects that the signal strength is less than -75 dBm.

STAs can roam between WACs in dual-link HSB mode.

In most cases, the signal strength of a STA should range from -45 dBm to -65 dBm.

NO.25 iMaster NCE-Campuslnsight provides Intelligent radio calibration for high-load APs to increase the frequency bandwidth. This function applies to both 5 GHz and 2.4 GHz frequency bands.

True

False

NO.26 Which of the following statements about VXLAN is false?

A Layer 2 VXLAN gateway forwards traffic to a VXLAN network and can also be used for Intra-subnet communication on the same VXLAN network.

Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces. Otherwise, users cannot communicate with each other through these interfaces.

A VBDIF interface is a logical interface created based on a BD. It is similar to a VLANIF interface on a traditional network.

A Layer 3 VXLAN gateway is used for inter-subnet communication on a VXLAN network and communication with external non-VXLAN networks.

NO.27 Which of the following statements are true about the WLAN site survey In different typical scenarios? (Select All that Apply)

In 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.

In 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.

In 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.

In 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.

NO.28 After multicast-to-unicast conversion is enabled on an AP’s air interface, which of the followings is the destination MAC address of multicast packets sent over the air interface?

Multicast MAC address

MAC address of the multicast source

Broadcast MAC address

MAC address of a STA

NO.29 Which of the followings is not a roaming optimization solution?

Proactive roaming

Smart roaming

Fast roaming using PMK caching

802.11r roaming

NO.30 On a campus network, which of the following problems may occur when you manually create a static VXLAN tunnel? (Select All that Apply)

Although the static VXLAN tunnel mode supports the distributed gateway scenario, the configuration involves a heavy workload and is complex to adjust.

A static VXLAN tunnel uses related protocols on the control plane, consuming device resources.

If N devices need to establish VXLAN tunnels, you need to manually configure the ingress replication list up to N x (N-l)/2 times.

Remote MAC addresses can be learned only through data flooding.

NO.31 Satellite positioning can achieve high positioning accuracy in both indoor and outdoor scenarios.

True

False

NO.32 Which of the following user access authentication modes are supported In Huawel’s CloudCampus Solution?
(Select All that Apply)

802. IX authentication

MAC address authentication

Portal authentication

NO.33 When a STA roams from API to AP2 at Layer 2, AP2 notifies its neighbors of from this STA is encapsulated in a tunnel and sent to API for forwarding.

True

False

NO.34 Master NCE-Campuslnsight can comprehensively record and analyze Interference. Which of the following parameters are recorded? (Select All that Apply)

Recommended channels

Interference fulfillment rate

Interference strength

Number of interference SSIDs

Air interface congestion fulfillment rate

NO.35 802. 11r fast roaming (over-the-air) is enabled on the WLAN shown in the figure. A STA roams from AP1 to AP2. Sort the steps in chronological order during the 802.11r fast roaming process between WACs.

NO.36 To which of the following scenarios is radio calibration applicable?

Enterprise office scenario

Rail transportation scenario

High-density scenario

WDS or mesh backhaul scenario

NO.37 Which of the fallowings is not an IPv6 address type?

Multicast address

Unicast address

Broadcast address

Anycast address

NO.38 Which of the following advantages does BSS coloring provide in Wi-Fi 6? (Select All that Apply)

Higher packet rate on the air interface

Enhanced encryption on the air interface

More efficient channel use

Higher concurrency in high-density scenarios
