Refer to the exhibit. The signal transmitted from the AP is reflected off a wall resulting in multipath interference at the client end.
Which statement is true？ （）
A. The transmitted signal from the AP arrives at the client at slightly different times resulting in phase shifting.
B. If signal 2 is close to 360 degrees out of phase with signal 1， the result is essentially zerosignal or a dead spot in the WLAN.
C. Multipath interference is less of an issue when using a DSSS technology because multipath is frequency selective.
D. If signal 1 is in phase with signal 2， the result is essentially zerosignal or a dead spot in the WLAN.
E. Multipath interference is solved by using dual antennas.

B. A Layer 3 device is needed for the ping command to be successful.
C. The ping command will be successful without any further configuration changes.
D. A trunk port will need to be configured on the link between Sw_A and Sw_B for the ping command to be successful.
Based on the network diagram and routing table output in the exhibit，
which of these statements is true？ （）
A. InterVLAN routing will not occur since no routing protocol has been configured.
B. InterVLAN routing has been configured properly， and the workstations have connectivity to each other.
