Cisco 640-722 Online Questions & Answers

• Question 101:

  An AP has been configured for personal wireless access to the Internet using appropriate security and cloaking. Which two items should be configured on the wireless client? (Choose two.)

  A. RF channel
  B. BSS
  C. PSK
  D. 802.1X/EAP
  E. broadcast SSID
  F. manual SSID
  G. IBSS
  C. PSK
  F. manual SSID

  Neighboring APs offering the same connection type and parameters use the same name, or service set identifier (SSID, which is a simple ASCII string providing a name to the connection). Neighboring APs offering the same connection use the same SSID, but each AP identifies itself by associating its radio MAC address to the SSID string. This associated MAC address is called the basic service set identifier (BSSID), and it enables stations to know which AP offers which SSID

• Question 102:

  What AnyConnect module can be used to provide a detailed scan list of the Wi-Fi environment?

  A. DART
  B. Telemetry
  C. Web Security
  D. NAM
  E. Posture
  A. DART

• Question 103:

  An engineer is troubleshooting why wireless clients have not been able to connect to the network. Where would an engineer verify the total number of excluded clients in the last day?

  A. Security > Miscellaneous
  B. Security > Rogues
  C. Alarms
  D. Events
  E. Clients > Troubleshoot
  F. Access Points
  A. Security > Miscellaneous

• Question 104:

  What are two modules of the CCX Lite program? (Choose two.)

  A. foundation
  B. voice
  C. RF power
  D. roaming
  A. foundation
  B. voice

  ---

  In summer 2011, Cisco separated the CCX features into four subfamilies to help vendors integrate only those features that are needed for their specific wireless clients (called application- specific devices, which are devices built for a specific function [for example, barcode scanners or VoWLAN phones] and therefore do not need all the CCX features that a data laptop would need). This is called the CCX Lite program, with four components:

  

  Foundation (for standard CCX features for connectivity and security)

  

  CCX Voice (for VoWLAN-specific features, such as QoS enhancements)

  

  Location

  

  Management (for connection reporting and troubleshooting)

• Question 105:

  Refer to the exhibit.

  

  Based on the diagram, what two design requirements must be met? (Choose two.)

  A. WGB is Autonomous
  B. WGB is Universal
  C. WGB can be Autonomous or Universal
  D. Upstream AP is Aironet
  E. Upstream AP is not Aironet
  F. Upstream AP can be any make/model
  A. WGB is Autonomous
  D. Upstream AP is Aironet

• Question 106:

  What is the purpose of the Log Analysis tab on the Client Troubleshooting page in Cisco WCS?

  A. After you click start, the tab shows debug information for the client that is trying to re- associate.
  B. The tab searches the logs for similar problems of other clients and generates a report.
  C. The tab generates a report from historical logs for the client that is having problems.
  D. The tab shows logs from the past hour for the client that is having problems.
  A. After you click start, the tab shows debug information for the client that is trying to re- associate.

  ---

  To view log messages logged against the client, click the Log Analysis tab. To begin capturing log messages about the client from the controller, click Start. To stop log message capture, click Stop. To clear all log messages, click Clear.

  Log messages are captured for ten minutes and then stopped automatically. A user must click Start to continue. To select log messages to display, click one of the links under Select Log Messages (the number between parentheses indicates

  the number of messages). The messages appear in the box. The message includes the following information:

  

  A status message

  

  The controller time

  

  A severity level of info or error (errors are displayed in red)

  

  The controller to which the client is connected

• Question 107:

  You need to set up an ad hoc connection to another client in a conference room to exchange files using Windows 7. Which two items do you need to create this connection? (Choose two.)

  A. SSID name
  B. RF channel
  C. 802.1X/EAP credentials
  D. pre-shared key
  E. Telnet
  F. IBSS name
  G. SSH
  D. pre-shared key
  F. IBSS name

  ---

  A wireless ad-hoc network is when two or more wireless nodes communicate directly on a peer- to-peer basis with no wireless network infrastructure. This is also referred to as an independent basic service set (IBSS). Wireless ad-hoc networks are typically formed on a temporary basis to rapidly enable communication between hosts, such as to exchange files during a spontaneous meeting or between hosts at home. The pre-shared key and the IBSS name need to be configured to allow for this.

• Question 108:

  Refer to the exhibit.

  

  Cisco WCS version 7.0 has a configuration mismatch with what is actually running in the controller. Which menu leads to the Audit Status Report?

  A. Security
  B. Monitor
  C. Configure
  D. Services
  E. Administration
  F. Tools
  C. Configure

  ---

  The Configure menu enables you to configure templates, controllers, access points, Ethernet switches, chokepoints, Wi-Fi TDOA receivers, config groups, auto provisioning, scheduled configuration tasks, profiles, ACS view servers, and TFTP servers on your network.

• Question 110:

  Which two types of encryption does Windows support for WPA2 security for wireless connections? (Choose two.)

  A. AES
  B. DES
  C. PGP
  D. TKIP
  E. WEP
  A. AES
  D. TKIP

  ---

  TKIP and AES are two different types of encryption that can be used by a Wi-Fi network. TKIP stands for "Temporal Key Integrity Protocol." It was a stopgap encryption protocol introduced with WPA to replace the very-insecure WEP encryption at the time. TKIP is actually quite similar to WEP encryption. TKIP is no longer considered secure, and is now deprecated. In other words, you shouldn't be using it. AES stands for "Advanced Encryption Standard." This was a more secure encryption protocol introduced with WPA2, which replaced the interim WPA standard. AES isn't some creaky standard developed specifically for Wi-Fi networks; it's a serious worldwide encryption standard that's even been adopted by the US government. For example, when you encrypt a hard drive with TrueCrypt, it can use AES encryption for that. AES is generally considered quite secure, and the main weaknesses would be brute-force attacks (prevented by using a strong passphrase) and security weaknesses in other aspects of WPA2.
