Cisco 200-355 Online Questions & Answers

• Question 581:

  What technology consists of small, low-power digital radios?

  A. LTE
  B. WiFi
  C. ZigBee
  D. Bluetooth
  C. ZigBee

  ---

  ZigBee is based on the IEEE 802.15.4 protocol for WPAN, and aims at developing hardware and applications with a low data rate but also low power consumption and low complexity --for example, to control sensors. ZigBee-based products can access up to 16 separate 5 MHz channels in the 2.4 GHz band and are not compatible with 802.11 devices. The maximum power of ZigBee is 60 mW. Devices use low consumption most of the time but can spike when needed: The impact on wireless networks can then be significant.

• Question 582:

  When an AP, in its default configuration mode, connects to a Cisco WLC, which methods are available for remote management access to an AP?

  A. SSL and SSH are available only after configuration by a Cisco WLC version 7.0.
  B. SSH only
  C. HTTPS, and SSH
  D. SSH and Telnet
  E. SSH and Telnet are available only after configuration by a Cisco WLC version 7.0.
  D. SSH and Telnet

  ---

  In Wireless LAN Controller release 5.0 and later, the controller supports the use of Telnet or Secure Shell (SSH) protocols to troubleshoot lightweight access points. You can use these protocols in order to make debugging easier, especially when the access point is unable to connect to the controller. You can configure Telnet and SSH support only through the controller CLI. http://www.cisco.com/c/en/us/support/docs/wireless/aironet-1200-series/70278-lap-faq.html

• Question 583:

  A network engineer at a retail store needs a wireless deployment that can be easily maintained and verified for PCI compliance. What solution will meet this need with the least work?

  A. Cloud
  B. Autonomous
  C. FlexConnect
  D. Centralized
  A. Cloud

• Question 584:

  Which two items are needed to discover the IP address of a new Cisco Aironet 1260 autonomous AP that just finished booting? (Choose two.)

  A. username = "cisco" and password = "cisco"
  B. username = "Admin" and password = "Cisco"
  C. username = none and password = "Cisco"
  D. show int vlan1
  E. show int bvi1
  F. show int gigabitethernet0
  G. show int radio0-802.11n
  H. show int radio1-802.11n
  C. username = none and password = "Cisco"
  E. show int bvi1

  ---

  Enter your username in the User Name field. The default username is Cisco. Enter the wireless device password in the Password field and press Enter. The default password is Cisco. The Summary Status page appears.

  The access point is configured with the factory default values including the IP address (set to receive an IP address using DHCP). To obtain the new IP address for an access point/bridge, you can use the show interface bvi1 CLI command. http://www.cisco.com/c/en/us/td/docs/wireless/access_point/12-4-25d-JA/Configuration/guide/cg_12_4_25d_JA/scg12-4-25d-JA-chap4-first.html

• Question 585:

  The introduction of consumer phones and tablets into enterprise WLANs can have an impact on 802.11a/b/ g/n deployments. The Apple iPhone 4 and iPad 2 are very common examples. Which statement best describes the abilities of these devices?

  A. The Apple iPhone 4 and the iPad 2 use 2.4 GHz and 5 GHz. The Apple iPhone 4 uses only one spatial stream and the iPad 2 uses two spatial streams.
  B. The Apple iPhone 4 uses only 2.4 GHz and the iPad 2 only uses 5 GHz. The Apple iPhone 4 uses only one spatial stream and the iPad 2 uses two spatial streams.
  C. The Apple iPhone 4 uses 2.4 GHz and the iPad 2 uses 2.4 GHz or 5 GHz. The Apple iPhone 4 only uses one spatial stream and the iPad 2 uses two spatial streams.
  D. The Apple iPhone 4 uses 2.4 GHz and the iPad 2 uses 2.4 GHz or 5 GHz. The Apple iPhone 4 and the iPad 2 use only one spatial stream.
  D. The Apple iPhone 4 uses 2.4 GHz and the iPad 2 uses 2.4 GHz or 5 GHz. The Apple iPhone 4 and the iPad 2 use only one spatial stream.

  ---

  The apple iPhone 4 and iPAD2 supports only 2.4 Ghz (no 5 Ghz) wireless networks. Support for 5Ghz networks was introduced with the Apple iPhone5 and the iPAD 3.

  A. IP parameters
  B. SNMP Parameters
  C. Mobility Parameters
  D. Telnet/SSH Parameters
  E. TFTP Parameters
  F. RADIUS Parameters
  A. IP parameters
  B. SNMP Parameters
  D. Telnet/SSH Parameters

• Question 587:

  Refer to the exhibit. Given the WLC data rate configuration, a control frame is sent at which speed?

  

  A. 9 Mbps
  B. 12 Mbps
  C. 48 Mbps
  D. 54 Mbps
  C. 48 Mbps

• Question 588:

  What are the channels you need to avoid not to have interference with DFS channels? (Choose three.)

  A. 52
  B. 136
  C. 124
  D. 161
  B. 136
  C. 124
  D. 161

• Question 589:

  Refer to the exhibit.

  

  If Cisco WCS version 7.0 needs to have APs added, relocated, or removed on a respective map, which menu leads to the correct location to make that adjustment?

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

• Question 590:

  When the enterprise-based authentication method is used for WPA2, a bidirectional handshake exchange occurs between the client and the authenticator. Which five options are results of that exchange being used on a controller-based network? (Choose five.)

  A. a bidirectional exchange of a nonce used for key generation
  B. binding of a Pairwise Master Key at the client and the controller
  C. creation of the Pairwise Transient Key
  D. distribution of the Group Transient Key
  E. distribution of the Pairwise Master key for caching at the access point
  F. proof that each side is alive
  A. a bidirectional exchange of a nonce used for key generation
  B. binding of a Pairwise Master Key at the client and the controller
  C. creation of the Pairwise Transient Key
  D. distribution of the Group Transient Key
  F. proof that each side is alive

  Regardless of whether WPA or WPA2 is used during the initial connection between the station and the AP, the two agree on common security requirements.
