Cisco 350-401 Online Questions & Answers

• Question 981:

  Which QoS component alters a packet to change the way that traffic is treated in the network?

  A. Marking
  B. Classification
  C. Shaping
  D. Policing
  A. Marking

  ---

  Explanation

  QoS Packet Marking refers to changing a field within a packet either at Layer 2 (802.1Q/p CoS, MPLS EXP) or Layer 3 (IP Precedence, DSCP and/or IP ECN). Reference: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_mqc/ configuration/xe- 16/qosmqc- xe-16-book/qos-mrkg.html

• Question 982:

  How is Layer 3 roaming accomplished in a unified wireless deployment?

  A. An EoIP tunnel is created between the client and the anchor controller to provide seamless connectivity as the client is associated with the new AP.
  B. The client entry on the original controller is passed to the database on the new controller.
  C. The new controller assigns an IP address from the new subnet to the client
  D. The client database on the original controller is updated the anchor entry, and the new controller database is updated with the foreign entry.
  D. The client database on the original controller is updated the anchor entry, and the new controller database is updated with the foreign entry.

• Question 984:

  Refer to the exhibit.

  

  Assuming the WLC's interfaces are not in the same subnet as the RADIUS server, which interface would the WLC use as the source for all RADIUS-related traffic?

  A. the interface specified on the WLAN configuration
  B. any interface configured on the WLC
  C. the controller management interface
  D. the controller virtual interface
  A. the interface specified on the WLAN configuration

  ---

  Explanation

  From the guide, the the tick box wasn't checked it would be A. - Check the RADIUS Server Overwrite interface check box to enable the per-WLAN RADIUS source support. When enabled, the controller uses the interface specified on the WLAN configuration as identity and source for all RADIUS related traffic on that WLAN

• Question 985:

  Refer to the exhibit.

  

  An engineer is configuring WebAuth on a Cisco Catalyst 9800 Series WLC. The engineer has purchased a third-party certificate using the FQDN of the WLC as the CN and intends to use it on the WebAuth splash page. What must be configured so that the clients do not receive a certificate error?

  A. Virtual IPv4 Hostname must match the CN of the certificate
  B. Virtual IPv4 Address must be set to a routable address
  C. Web Auth Intercept HTTPs must be enabled
  D. Trustpoint must be set to the management certificate of the WLC
  A. Virtual IPv4 Hostname must match the CN of the certificate

• Question 986:

  A customer has a wireless network deployed within a multi-tenant building. The network provides client access, location-based services, and is monitored using Cisco DNA Center. The security department wants to locate and track malicious devices based on threat signatures.

  Which feature is required for this solution?

  A. Cisco aWIPS policies on the WLC
  B. Cisco aWIPS policies on Cisco DNA Center
  C. malicious rogue rules on the WLC
  D. malicious rogue rules on Cisco DNA Center
  B. Cisco aWIPS policies on Cisco DNA Center

• Question 988:

  An engineer is configuring Local WebAuth on a Cisco Wireless LAN Controller. According to RFC 5737

  Which VIRTUAL IP address must be used in this configuration?

  A. 192.0.2.1
  B. 172.20.10.1
  C. 1.1.1.1
  D. 192.168.0.1
  A. 192.0.2.1

  ---

  Explanation

  The virtual interface IP address (IPv4 or IPv6) is used only in communications between the controller and wireless clients. It serves as the redirect address for the web authentication login page. It is recommended that you configure a nonroutable IP address for the virtual interface, ideally not overlapping with the network infrastructure addresses. Use one of the options proposed in RFC 5737, for example, 192.0.2.0/24, 198.51.100.0/24, and 203.0.113.0/24 networks.

• Question 989:

  Refer to the exhibit.

  

  Which antenna emits this radiation pattern?

  A. omnidirectional
  B. RP-TNC
  C. dish
  D. Yagi
  A. omnidirectional

• Question 990:

  Which IP SLA operation requires the IP SLA responder to be configured on the remote end?

  A. ICMP echo
  B. UDP jitter
  C. CMP jitter
  D. TCP connect
  B. UDP jitter

  ---

  Explanation

  Cisco IOS IP SLA Responder is a Cisco IOS Software component whose functionality is to respond to Cisco IOS IP SLA request packets. The IP SLA source sends control packets before the operation starts to establish a connection to the responder. Once the control packet is acknowledged, test packets are sent to the responder. The responder inserts a time-stamp when it receives a packet and factors out the destination processing time and adds time-stamps to the sent packets. This feature allows the calculation of unidirectional packet loss, latency, and jitter measurements with the kind of accuracy that is not possible with ping or other dedicated probe testing.

  The IP SLAs responder is a component embedded in the destination Cisco device that allows the system to anticipate and respond to IP SLAs request packets. The responder provides accurate measurements without the need for dedicated probes.

  UDP Jitter measures the delay, delay variation(jitter), corruption, misorderingand packet lossby generating periodic UDP traffic. This operation always requires IP SLA responder.
