Several users with older devices are reporting intermittent connectivity while in an outdoor patio area. After
some research, the network administrator determines that an outdoor WAP might help with the issue. However,
the company does not want the signal to bleed into the building and cause interference. Which of the following
should the network administrator perform to BEST resolve the issue?


A. Disable the SSID broadcast on the WAP in the patio area.
B. Install a WAP and enable 5GHz only within the patio area.
C. Install a directional WAP in the direction of the patio.
D. Install a repeater on the back wall of the patio area.

An office area contains two PoE-enabled WAPs. After the area was remodeled, new cable uplinks were
installed in the ceiling above the fluorescent lights. However, after the WAPs were reconnected, users reported
slowness and application errors. An intern reviewed the network and discovered a lot of CRC errors. A network
engineer reviewed the intern's work and realized UTP cabling was used. Which of the following is the MOST
likely cause of the CRC errors?


A. Insufficient power at the antennas
B. PoE and UTP incompatibility
C. Electromagnetic interference
D. Wrong cable pinout

A network administrator is designing a wireless network. The administrator must ensure a rented office space

B. RSSI roaming threshold
C. RF attenuation ratio
D. EIRP power setting
