What is the purpose of DHCP Option 43, and how is it used with WLANs?

  • A. It provides clients with a temporary IP address on a restricted VLAN until 802.1X authentication is completed. Then the client receives its long-term IP address.
  • B. It provides IP address bindings for specific network nodes that require long-term IP address assignments. WLAN controllers are configured to use Option 43 to receive long- term IP address leases that are centrally managed with DHCP.
  • C. It supports vendor-specific IP address attributes for node discovery purposes. APs use Option 43 with vendor class identifiers to obtain the IP address of a centralized WLAN controller.
  • D. It integrates a DHCP server with AAA servers and user databases to dynamically assign IP addresses to client devices. During 802.1X, the AAA server uses Option 43 to notify the DHCP server what IP pool the clientsaddress should be drawn from.


Answer : C

Which definition correctly describes the local MAC variation of the centralized WLAN architecture?

  • A. All MAC functions are performed by the AP. A minimal subset of network control is offloaded to the WLAN controller along with management and monitoring functions.
  • B. PHY functions are performed directly by the AP. MAC functions are divided almost equally between the WLAN controller and the AP, according to the time sensitivity of the feature or service.
  • C. The AP provides the RF termination point for the WLAN, but performs very few of the WLAN functions or services. The WLAN controller performs all MAC functions and the AP is very simple and lightweight.
  • D. All RF-, data-, and control-related WLAN functions are performed by the AP. APs coordinate network services with one another and are managed by a WNMS, so no WLAN controller is used in this architecture.


Answer : A

You are testing a VoWLAN deployment, and your communication measurements show a certain amount of lost packets. What would be an acceptable packet error rate value to still provide acceptable call quality?

  • A. There should be 0% error in a VoWLAN type of deployment
  • B. No more than 1% PER max should be acceptable
  • C. No more than 4% PER max should be acceptable
  • D. No more than 8% PER max should be acceptable


Answer : B

When deploying long-distance 802.11 bridge links (10 miles / 16 km), what parameter may be critical for improving data flow by reducing retries caused by the long distances?

  • A. The sequence control field value
  • B. The acknowledgement timeout threshold
  • C. The minimum transmit data rate value
  • D. The CTS-to-self threshold


Answer : B

What are some advantages of designing guest access with all guest users tunneled directly into the DMZ?

  • A. Allows a single SSID with different authentication/encryption models to be used for all WLAN services for corporate users and guests
  • B. Minimizes configuration requirements for segmentation and filtering of guest traffic across internal LAN
  • C. The border firewall configuration will not require any additional rules to pass guest traffic to the DMZ controller
  • D. Enhances performance of web proxy servers in the DMZ for guest Internet traffic
