An existing wireless network was designed to support data traffic only. You must now install context Aware services for location tracking changes must be applied to the existing wireless network to increase the location accuracy? (Chose two)

1. A. Add access points along the perimeter of the coverage area.
2. B. Increase the access point density to create an average inter-access point distance of less than 40 feet or 12.2 meters
3. C. Use directional antennas to provide more cell overlapping
4. D. Install additional access points in monitor mode where the co-channel interference would otherwise be affected

When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two )

1. A. Serialization delays are invariable because they depend only on the line rate of the interface
2. B. Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.
3. C. Serialization delay is the time required to transmit the packet on the physical media.
4. D. Serialization delays are variable because they depend only on the size of the packet being serialized
5. E. Serialization delay depends not only on the line rate of the interface but also on the size of the packet
