• Question 273:

  What is wrong about the description of the omnidirectional antenna below?

  A. Omnidirectional antenna distributes the signal evenly over a 360-degree omnidirectional area around the center point
  B. The omnidirectional antenna has a lobe width of 360 degrees horizontally
  C. The omnidirectional antenna has strong energy gathering ability and the direction of the signal is good.

• Question 274:

  The following description of the Mesh profile is wrong?

  A. In a Mesh BSS, all Mesh STAs have the same Mesh profile. If all the parameters of the Mesh profile are matched, the Mesh profile is considered to be consistent.
  B. Mesh profile contains the following contents, Mesh ID, A path selection protocol identifier (fixed), A path metric identifier (fixed)
  C. After creating a Mesh BSS or becoming a BSS member, a Mesh STA will generate a Mesh profile.
  D. Unless the Mesh profile leaves the Mesh BSS (the Mesh STA is already a member of the Mesh BSS), the Mesh STA does not change its Mesh profile.
  C. After creating a Mesh BSS or becoming a BSS member, a Mesh STA will generate a Mesh profile.

• Question 275:

  The following description of the directional antenna is wrong?

  A. Directional antennas are radiated in a range of angles on a horizontal pattern, which is commonly referred to as a directional antenna.
  B. The directional antenna has the strongest energy gathering ability, and the direction of the signal is very good.
  C. When the number of remote link points is small, or the angular orientation is quite concentrated, the use of directional antennas is the most effective solution.
  D. Directional antennas have only the main flap for practical use, so the side lobes can be ignored.
  D. Directional antennas have only the main flap for practical use, so the side lobes can be ignored.
