• Question 173:

  A. antenna bandwidth
  B. antenna gain
  C. cable loss
  D. receiver sensitivity
  E. SSID
  F. transmission power
  B. antenna gain
  C. cable loss
  F. transmission power

• Question 174:

  What is fading?

  A. Another signal source is producing energy on the channel in which you are trying to operate.
  B. The desired signal reaches the receiving antenna via multiple paths, each of which has a different propagation delay and path loss.
  C. A time-varying change in the path loss of a link with the time variance governed by the movement of objects in the environment, including the transmitter and receiver themselves.
  D. A function of the frequency and should be provided in the cable specification by the vendor.
  E. The minimum signal level for the receiver to be able to acceptably decode the information.
  F. The time delay from the reception of the first instance of the signal until the last instance.
  C. A time-varying change in the path loss of a link with the time variance governed by the movement of objects in the environment, including the transmitter and receiver themselves.

• Question 175:

  A network engineer is troubleshooting a LAP that is unable to join the controller and receives this message:

  LWAPP_CLIENT_ERROR_DEBUG: No more AP manager IP addresses remain

  What does the log indicate?

  A. An AP manager has the same IP address as another AP manager.
  B. A LAP has the same IP address as the AP manager.
  C. Two or more LAPs have the same IP address.
  D. Two or more controllers have the same IP address.
  B. A LAP has the same IP address as the AP manager.

  ---

  This is another common issue that is seen when the AP tries to join the WLC. You might see this error message when the AP tries to join the controller. No more AP manager IP addresses remain One of the reasons for this error message is

  when there is a duplicate IP address on the network that matches the AP manager IP address. In such a case, the LAP keeps power cycling and cannot join the controller.

  The debugs will show that the WLC receives LWAPP discovery requests from the APs and transmits a LWAPP discovery response to the APs. However, WLCs do not receive LWAPP join requests from the APs.

  In order to troubleshoot this issue, ping the AP manager from a wired host on the same IP subnet as the AP manager. Then, check the ARP cache. If a duplicate IP address is found, remove the device with the duplicate IP address or change

  the IP address on the device so that it has a unique IP address on the network.

  The AP can then join the WLC.

• Question 176:

  You are configuring SNMPv1/v2c on a WLC. What should you do for improved security?

  A. Remove the default SNMPv1 community.
  B. Remove the default SNMPv1 and SNMPv2 communities.
  C. Remove the default SNMPv2 community.
  D. Remove the default SNMPv3 users.
  B. Remove the default SNMPv1 and SNMPv2 communities.

  ---

  The controller has commonly known default values of "public" and "private" for the read-only and read-write SNMP community strings. Using these standard values presents a security risk. If you use the default community names, and since

  these are known, the community names could be used to communicate to the controller using SNMP. Therefore, we strongly advise that you change these values.

  Step 1

  Choose Management and then Communities under SNMP. The SNMP v1 / v2c Community page appears.

  Step 2

  If "public" or "private" appears in the Community Name column, hover your cursor over the blue drop-down arrow for the desired community and choose Remove to delete this community.

  Step 3

  Click New to create a new community. The SNMP v1 / v2c Community > New page appears.

  Step 4

  In the Community Name text box, enter a unique name containing up to 16 alphanumeric characters. Do not enter "public" or "private." Step 5

  In the next two text boxes, enter the IPv4/IPv6 address and IP Mask/Prefix Length from which this device accepts SNMP packets with the associated community and the IP mask.

  Step 6

  Choose Read Only or Read/Write from the Access Mode drop-down list to specify the access level for this community.

  Step 7

  Choose Enable or Disable from the Status drop-down list to specify the status of this community.

  Step 8

  Click Apply to commit your changes.

  Step 9

  Click Save Configuration to save your settings.

  Step 10

  Repeat this procedure if a "public" or "private" community still appears on the SNMP v1 / v2c Community page.

• Question 177:

  Which EAP protocol requires a certificate only on the server side?

  A. EAP-PEAP
  B. EAP-FAST
  C. EAP-TLS
  D. EAP-SSL
  A. EAP-PEAP

  ---

  PEAP is not an encryption protocol; as with other EAP types it only authenticates a client into a network.

  PEAP uses only server-side public key certificates to authenticate clients by creating an encrypted SSL/TLS tunnel between the client and the authentication server, which protects the ensuing exchange of authentication information from casual inspection. http://wiki.freeradius.org/protocol/EAP-PEAP

• Question 178:

  Refer to the exhibit.

  

  An engineer is implementing a new network design that includes a port channel to connect an MDS core switch and an VPN switch. Which two Fibre Channel port types must be used to create the Fibre Channel port channel? (Choose two.)

  A. NL Port
  B. F Port
  C. NP Port
  D. E Port
  E. N Port
  F. TL Port
  B. F Port
  C. NP Port

• Question 179:

  You plan to deploy a Cisco 5760 WLC. Which three components are part of the mobility architecture? (Choose three.)

  A. a mobility oracle
  B. Cisco ISE
  C. a switch peer group
  D. Cisco Prime Infrastructure
  E. a mobility controller F. an AP group
  A. a mobility oracle
  C. a switch peer group
  E. a mobility controller F. an AP group

• Question 180:

  An AP using version 8.0 MR1 broadcasts a Layer 3 CAPWAP discovery message on the local IP subnet. Which step does the AP take next?

  A. Determine if the controller responses include the primary controller.
  B. Determine if the controller responses include the master controller.
  C. Send a discovery request using DHCP option 43.
  D. Send a discovery request using DNS.
  E. Send a discovery request using locally stored information on the AP.
  F. Send a discovery request using OTAP.
  E. Send a discovery request using locally stored information on the AP.

  If the LAP was registered to a WLC in a previous deployment, the LAP maintains the list of WLC IP addresses locally in NVRAM. The stored WLC IP addresses include all of the WLCs that are in previously joined WLC "mobility groups". This is the discovery process: http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/70333-lap-registration.html#topic2
