You're replacing a wired business network with an 802.11g wireless network. You currently use Active Directory on the company network as your directory service. The new wireless network has multiple wireless access points, and you want to use WPA2 on the network. What should you do to configure the wireless network? (Select two.)
Answer
A) Configure devices to run in infrastructure mode.
B) Install a RADIUS server and use 802.1x authentication.
C) Use shared secret authentication.
D) Use open authentication with MAC address filtering.
E) Configure devices to run in ad hoc mode.
What is A and B:
Configure devices to run on infrastructure mode and Install a RADIUS server and use 802.1x
500
Your wireless network consists of multiple 802.11n access points that are configured as follows:
- SSID (hidden): CorpNet
- Security: WPA2-PSK using AES
- Frequency: 5.75 GHz
- Bandwidth per channel: 40 MHz
Because of your facility's unique construction, there are many locations that do not have a clear line of sight between network clients and access points. As a result, radio signals are reflected along multiple paths before finally being received. The result is distorted signals that interfere with each other.
What should you do?
Answer
A) Reduce the power of the access point radio signals.
B) Implement antenna diversity.
C) Switch to RADIUS authentication for wireless clients.
D) Install directional access points.
What is B) Implement antenna diversity
