QUESTION NO: 1
When the WLAN network supports inter-AC roaming, multiple ACs establish a full connection through the inter-AC tunnel. If the user of the Layer 3 roaming to other ACs can still receive broadcast packets from the original subnet and simply broadcast the broadcast packets to other ACs through the roaming tunnel, a broadcast loop may be formed.

A. Correct B. False

Correct Answer: A

QUESTION NO: 2
Which of the following statements about power adjustment is FALSE?

A. An AP's transmit power determines its radio coverage area. APs with higher power have larger coverage areas. B. During dynamic power adjustment, it is necessary to select an optimal power to balance the signal coverage with system capacity. C. A traditional method to control the radio power is to set the transmit power to the maximum value to maximize the radio coverage area. However, a high transmit power may cause interference to other wireless devices. D. The global radio calibration algorithm includes the Dynamic Channel Allocation (DCA) algorithm and Transmit Power Control (IPC) algorithm.

Correct Answer: D

QUESTION NO: 3
Which of the following statements about bad balancing are TRUE? (Multiple Choice)

A. A dual-band AP can join two load balancing groups. B. Each load balancing group supports a maximum of 32 members. C. An AP radio can join only one load balancing group. D. If dual-band APs are used, traffic is load balanced among APs working on the same frequency band.

Correct Answer: A,C,D

QUESTION NO: 4
When the engineer adjusted the directional antenna, it was found that when the antenna was placed away from the other antenna, the signal would drop and the signal would increase slightly. What caused the increase of this signal?

A. Sideband B. Frequency harmonics C. Signal reflection D. Side lobes

Correct Answer: D

QUESTION NO: 5
In the WLAN network, the following is true about the WIDS illegal device?

A. The illegal client refers to the client that is not online at the AC. B. Illegal bridge refers to a WDS device that is not managed by this AC. C. An illegal AP refers to an AP that does not belong to this AC. D. All Ad-hot devices are illegal devices

Correct Answer: B,D

QUESTION NO: 6
What is wrong about the return type VAP description below?

A. Establish routing topology between nodes by forwarding route management packets on the backhaul link B. Complete the MESH connection establishment and data return function C. Multiple RF backhaul VAPs can be created for each RF D. Complete MP neighbor discovery

Correct Answer: C

QUESTION NO: 7
Which of the following statements about N+1 backup is TRUE?

A. The models and software versions of the active and standby ACs must be the same. B. A standby AC can provide backup services for multiple active ACs. This mode reduces device purchase costs and has higher reliability than VRRP HSB. C. The active and standby ACs can be of different models but must use the same software version. D. N+1 backup is a cold backup mode, which backs up AP and STA information.

Correct Answer: C

QUESTION NO: 8
Which statements about the MPP on a Mesh network are TRUE? (Multiple Choice)

A. An MPP connects to a Mesh network or another type of network, and communicates with MP/MAP within the Mesh network. B. An MPP provides the Portal function and allows internal nodes to communicate with external networks. C. MPPs do not support redundancy. D. An MPP is also called Mesh gateway.

Correct Answer: A,B,D

QUESTION NO: 9
When the STA uses the WPA2-802.1x security policy and supports fast roaming, the STA only needs to perform key negotiation, but does not need to pass 802.lx authentication again during roaming.

A. FALSE B. TRUE

Correct Answer: B

QUESTION NO: 10
Which is NOT Mesh networking?

A. (a) B. (d) C. (b) D. (c)

Correct Answer: A

QUESTION NO: 11
