H12-321-ENU問題集、Huawei実際の試験問題

質問 1

Which of the following processing methods are TRUE, to solve the packet congestion on the tunnel? (Multiple Choice)

A. After broadcast/multicast packets are transparently transmitted to the FAC, the FAC converts the packets to unicast packets and forwards the packets over a specific tunnel based on the home AP connected to it.

B. The HAC at the tunnel ingress discards unknown unicast packets.

C. The HAC discards broadcast or multicast ARP, ND, DHCP, and mDNS packets to prevent loops.

D. The FAP discards unknown unicast packets and forwards other packets to roaming STAs.

正解: A,B

質問 2

STAs do not need to support channel switching without service interruption for implementing this function.

A. FALSE

B. TRUE

正解: A

質問 3

Which of the following statements about power adjustment is FALSE?

A. 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.

B. An AP's transmit power determines its radio coverage area. APs with higher power have larger coverage areas.

C. The global radio calibration algorithm includes the Dynamic Channel Allocation (DCA) algorithm and Transmit Power Control (TPC) algorithm.

D. During dynamic power adjustment, it is necessary to select an optimal power to balance the signal coverage with system capacity.

正解: C

質問 4

Which of the following servers is the directory server?

A. RADIUS server

B. DNS server

C. Portal server

D. AD server

正解: D

質問 5

What does OU in the directory server refer to?

A. Domain

B. User group

C. Organization unit

D. User

正解: C

質問 6

Which of the following statements are TRUE about the application scenarios and features of the ACs? (Multiple Choice)

A. The native AC such as the X1E card applies to scenarios where the wired and wireless users are managed separately.

B. The native AC such as the X1E card provides higher forwarding performance than the independent AC, such as the AC6605. In addition, the native AC can implement link and device redundancy, making the WLAN more reliable.

C. The independent AC such as the AC6605 applies to scenarios which require unified construction of wired and wireless networks and unified management on wired and wireless users.

D. The AC card such as ACU2 applies to large-scale networks and scenarios which have insufficient rack space but require capacity expansion.

正解: B,D

質問 7

In which of the following figures are Fresnel zones correctly marked? (Multiple Choice)

A. (b)

B. (d)

C. (a)

D. (c)

正解: C,D

質問 8

A company needs to construct a large WLAN. Since the company has a large number of employees, the service traffic is large. The company may need to expand the WLAN capacity in the future.
Which of the following statements are TRUE? (Multiple Choice)

A. Configure a security policy of high security.

B. Deploy the ACU2 on the network.

C. Configure the VLAN pool.

D. Deploy the AC6005 on the network.

正解: A,B,C

質問 9

In smart roaming, an AP specifies the target AP for 802.11v-capable STAs. In this way, STAs actively roam to the target AP, and the original AP does not need to kick the STAs offline.

A. FALSE

B. TRUE

正解: B

質問 10

Which of the following statements about backup CAPWAP tunnel setup are TRUE? (Multiple Choice)

A. After receiving the Join Request message, the AC sets up a CAPWAP tunnel with the AP but does not deliver configurations to the AP.

B. The AP sends a Discovery Request message to the standby AC in broadcast mode.

C. The AP sends a Join Request message, notifying the standby AC that the configurations have been delivered.

D. The AP and ACs set up the primary and backup tunnels at the same time and complete configuration delivery.

正解: A,C
