A. Brute force

B. Weak IV attack

C. Flooding attack

D. Spoofing attack

Correct Answer: C,D

Question 2

Which statements about the MPC's default routing entries in the figure are TRUE? (Multiple Choice)

A. The next hop is D, and the number of hops is 2.

B. The next hop is B, and the number of hops is 2.

C. The next hop is B, and the number of hops is 3.

D. The next hop is D, and the number of hops is 3.

Correct Answer: B,D

Question 3

If an online AP on the active AC is added offline to the standby AC, the AP status is displayed as fault on the standby AC. In this case, you can run the undo hsb enable command to disable the HSB function in the HSB group view on the standby AC, and then run the hsb enable command to enable the HSB function. In this way, information on the active and standby ACs is the same and the AP status is displayed as standby on the standby AC.

A. FALSE

B. TRUE

Correct Answer: B

Question 4

A. IP address

B. Time

C. SSID

D. Device name

Correct Answer: A,B,C

Question 5

A. The APs an STA can roam to must be in the same extended service set (ESS).

B. The APs an STA can roam to do not need to have overlapping signal coverage.

C. The APs an STA can roam to must be in the same basic service set (BSS).

D. The APs an STA can roam to must have overlapping signal coverage.

Correct Answer: A,D

Question 6

Which is the correct sequence for a VLAN pool to assign VLANs to terminals?
1. A terminal accesses the network from the assigned VLAN.
2. Check for the VLAN pool and VLAN assignment algorithm bound to the VAP.
3. The terminal connects to the VAP.
4. Allocate a VLAN to the terminal based on the VLAN assignment algorithm.

A. 3- >2->4->1

B. 3->4->2->1

C. 4->3->2->1

Question 8

Which of the following statements about the first Fresnel zone is FALSE?

A. The first Fresnel zone makes RF signals diffract or bend even through it is blocked.

B. Under any circumstances, the proportion of the area blocked by obstacles in the first Fresnel zone cannot exceed 60%.

C. The first Fresnel zone affects RF communication integrity even though it is partially blocked.

D. Signal diffraction reduces RF energy received by antennas or even interrupts the communication link.

Correct Answer: B
