Cisco 200-355 Online Questions & Answers

• Question 21:

  A customer is using the access point GUI to upgrade the software on an autonomous access point to convert it to a lightweight access point. Which two transfer protocols are valid for conducting this transfer from the WLC? (Choose two.)

  A. FTP
  B. RCP
  C. SFTP
  D. HTTP
  E. SCP
  F. TFTP
  D. HTTP
  F. TFTP

• Question 22:

  If an antenna has a dBd of 8.6, what is the dBi value?

  A. 8.6
  B. 6.46
  C. 10.74
  D. 6.2
  E. 12.88
  C. 10.74

  ---

  Antenna performance is measured in dBi (the antennas gain/loss over a theoretical isotropic antenna) dBd

  (the antennas gain/loss over a dipole antenna) dBi = dBd + 2.15 dBd = dBi - 2.15

• Question 24:

  What is the European Standard equivalent of the FCC?

  A. IEEE
  B. ISM
  C. ETSI
  D. ITU
  C. ETSI

• Question 25:

  The network administrator receives complaints of slow wireless network performance and performs a sniffer trace of the wireless network in preparation for migration to 802.11n. The sample capture shows frames that contains AP beacons with NonERP_Present bit set to 1 and frames with RTS/CTS. Which two conclusions can be interpreted from these frames? (Choose two.)

  A. The network is performing slowly because 802.11n clients are already mixed with 802.11g clients.
  B. The network is performing slowly because 802.11b clients still exist in the network.
  C. The network is performing slowly because a wireless client is incorrectly configured, which results in RF interference.
  D. Possible 802.11b wireless clients are located only in the AP cell radius where the sniffer capture was performed.
  E. Possible 802.11b wireless clients could be located anywhere in the wireless network.
  B. The network is performing slowly because 802.11b clients still exist in the network.
  E. Possible 802.11b wireless clients could be located anywhere in the wireless network.

  If an ERP AP hears a beacon from an AP where the supported data rates contain only 802.11b or 802.11 DSSS rates, it will enable the NonERP_Present bit in its own beacons, enabling protection mechanisms in its BSS. In simpler terms, if

  an 802.11g AP hears a beacon frame from an 802.11 or 802.11b access point or ad hoc client, the protection mechanism will be triggered.

• Question 26:

  An engineer wants to setup a mobility anchor for the Guest WLAN (Choose three.)

  A. based on a single server licensing system
  B. used for wireless planning
  C. used for real-time tracking of multiple clients
  D. used for wireless management
  E. used for RF fingerprinting
  F. based on a per server licensing system
  A. based on a single server licensing system
  B. used for wireless planning
  D. used for wireless management

  A. config network ssh disable
  B. config network secureweb enable
  C. config network secureweb cipher-option high enable
  D. config network secureweb cipher-option sslv2 disable
  E. config network webmode enable
  B. config network secureweb enable
  C. config network secureweb cipher-option high enable

• Question 28:

  When adding a controller to manage through Cisco WCS, which address type is used and which SNMP function does the Cisco WCS perform?

  A. The controller is managed through its MAC address and the Cisco WCS acts as a SNMP TRAP authenticator.
  B. The IP address of the controller is used and the Cisco WCS acts as a SNMP TRAP receiver.
  C. The controller is managed through its MAC address and the Cisco WCS acts as a SNMP agent.
  D. The controller connects through its MAC address to the Cisco WCS and the Cisco WCS uses the SNMP to manage the controller for all configured SNMP parameters.
  B. The IP address of the controller is used and the Cisco WCS acts as a SNMP TRAP receiver.

• Question 29:

  What is the equivalent of 26 dBm in milliwatts?

  A. 4 mW
  B. 40 mW
  C. 100 mW
  D. 400 mW
  E. 1000 mW
  D. 400 mW

  ---

  dBm = log10 (mW)*10 mW =10^(dBm/10) Samples: 40 dBm=10.00 watts 36 dBm=4.00 watts 30 dBm=1.00 watts 27 dBm=500 milliwatts 26 dBm=400 milliwatts
