Which two features or capabilities are valid options for both an Autonomous WLAN solution
and a Lightweight WLAN solution? (Select two)
A.
PoE capability
Users need only remember their normal ID and password for access to their laptop, the
wired network, and the wireless network, and they only have to enter their credentials once
each session regardless of the transport medium they are using.
B.
Use of Cisco Secure Access Control Server (ACS) for security
C.
Cisco IOS software for configuration
D.
Cisco Wireless Control System (WCS) for management
E.
Use of a Cisco Wireless Location Appliance location for tracking
A.
PoE capability
Users need only remember their normal ID and password for access to their laptop, the
wired network, and the wireless network, and they only have to enter their credentials once
each session regardless of the transport medium they are using.
Explanation:
Cisco Aironet access points provide secure, manageable, high-performance, and reliable
connectivity with exceptional range and performance. Lightweight access points operate in
conjunction with Cisco wireless LAN controllers and the Wireless Control System (WCS).
Standalone (autonomous) access points are managed by CiscoWorks Wireless LAN
Solution Engine (WLSE) or CiscoWorks WLSE Express
Cisco Aironet Access Points
When originally deployed, the Cisco Aironet 350 Series Access Point was selected as the
standard access point for both autonomous and lightweight solutions. The Cisco Aironet 350
Series was the most advanced, fully featured wireless access point available. It supported
the 802.11b protocol standard (the most advanced at that time), which provides data rates of
up to 11 Mbps. The Cisco Aironet 350 Series also supported inline Power over Ethernet
(PoE), which greatly simplifies installation and reduces costs by eliminating the need for
separate, dedicated power cabling to the main supply.
Cisco Secure Access Control Server (ACS)
The Cisco Secure ACS is used as the standard AAA server for the global WLAN and for
other recently introduced services such as 802.1x-based port authentication for wired
Ethernet ports in public areas and Network Access Control (NAC), part of the Cisco SelfDefending Network security strategy. Pairs of Cisco Secure ACSs were deployed at strategic
locations worldwide.
The value of using a globally distributed AAA architecture instead of a single AAA server
was highlighted by the WLAN deployment. Because of the greater load that a WLAN creates
for AAA, due to authentications and reauthentications (as the client device roams from AP to
AP), it was important to ensure that all users did not have to rely upon a single, centralized
server. This would have introduced unacceptable delays for users in geographically remote
areas. As such, at 13 different locations around the world, Cisco placed two ACS servers, in
a load-balanced configuration, that served as AAA servers for that local geographical region.
The ACS servers are fully integrated with the Cisco Active Directory domain structure,
enabling a single sign-on (SSO) capability. Effectively, AD user credentials are used not only
for access to their laptops and wired network but also to provide transparent authentication
to the wireless network. SSO has greatly reduced the client impact for users and has helped
ensure a common, user-friendly experience across platforms and transport medi
