A wireless consultant is designing a high-density wireless network for a lecture hall for 1000 students Which antenna type is recommended for this environment?

• A.sector antenna
• B.dipole antenna
• C.parabolic dish
• D.omnidirectional antenna

Correct Answer: D

Explanation
Directional antennas Directional antennas come in many different styles and shapes. An antenna does not offer any added power to the signal; it simply redirects the energy it receives from the transmitter. By redirecting this energy, it has the effect of providing more energy in one direction and less energy in all other directions. As the gain of a directional antenna increases, the angle of radiation usually decreases, providing a greater coverage distance but with a reduced coverage angle. Directional antennas include patch antennas and parabolic dishes. Parabolic dishes have a very narrow RF energy path, and the installer must be accurate in aiming these types of antennas at each other.

This type of antenna is used when coverage in all directions from the antenna is required. The standard 2.14-dBi "rubber duck" is one style of omnidirectional antenna.
Omnidirectional antenna
-> Therefore Omnidirectional antenna is best suited for a high-density wireless network in a lecture hall.

In which two ways does the routing protocol OSPF differ from EIGRP? (Choose two.)

• A.OSPF supports an unlimited number of hops. EIGRP supports a maximum of 255 hops.
• B.OSPF is distance vector protocol. EIGRP is a link-state protocol.
• C.OSPF supports only equal-cost load balancing. EIGRP supports unequal-cost load balancing.
• D.OSPF supports unequal-cost load balancing. EIGRP supports only equal-cost load balancing.
• E.OSPF provides shorter convergence time than EIGRP.
