• Question 813:

  Which protocol is responsible for data plane forwarding in a Cisco SD-Access deployment?

  A. VXLAN

  B. IS-IS

  C. OSPF

  D. LISP

  Correct Answer: A

  In SD-Access the control plane is based on LISP (Locator/ID Separation Protocol), the data plane is based on VXLAN (Virtual Extensible LAN), the policy plane is based on Cisco TrustSec, and the management plane is enabled and powered

  by Cisco DNA Center.

  C. in an HTML format

  D. as modules within a tree

  Correct Answer: B

• Question 815:

  Refer io me exhibit.

  

  An engineer configures the trunk and proceeds to configure an ESPAN session to monitor VLANs10. 20. and 30. Which command must be added to complete this configuration?

  A. Device(config.mon.erspan.stc)# no filter vlan 30

  B. Devic(config.mon.erspan.src-dst)# no vrf 1

  C. Devic(config.mon.erspan.src-dst)# erspan id 6

  D. Device(config.mon-erspan.Src-dst)# mtu 1460

  Correct Answer: A

  You cannot include source VLANs and filter VLANs in the same session https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/16-5/configuration_guide/nmgmt/b_165_nmgmt_3850_cg/b_165_nmgmt_3850_cg_chapter_0111.pdf

• Question 816:

  Refer to the exhibit.

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

• Question 817:

  Refer to the exhibit.

  

  A network engineer must be notified when a user switches to configuration mode. Which script should be applied to receive an SNMP trap and a critical-level log message?

  A. action 1.0 snmp-trap strdata "Configuration change alarm" action 1.0 syslog priority critical msg "Configuration change alarm"

  B. action 1.0 snmp-trap strdata "Configuration change alarm" action 2.0 syslog msg "Configuration change alarm"

  C. action 1.0 snmp-trap strdata "Configuration change alarm" action 1.1 syslog priority critical msg "Configuration change alarm"

• Question 818:

  Refer to the exhibit. The administrator troubleshoots an EtherChannel that keeps moving to err-disabled. Which two actions must be taken to resolve the issue? (Choose two.)

  

  A. Reload the switch to force EtherChannel renegotiation

  B. Ensure that interfaces Gi1/0/2 and Gi1/0/3 connect to the same neighboring switch.

  C. Ensure that the switchport parameters of Port channel1 match the parameters of the port channel on the neighbor switch

  D. Ensure that the corresponding port channel interface on the neighbor switch is named Portchannel1.

  E. Ensure that the neighbor interfaces of Gi1/0/2 and Gi/0/3 are configured as members of the same EtherChannel

  Correct Answer: BE

  This feature was first implemented in order to handle special collision situations in which the switch detected excessive or late collisions on a port. Excessive collisions occur when a frame is dropped because the switch encounters 16 collisions in a row. Late collisions occur after every device on the wire should have recognized that the wire was in use. Possible causes of these types of errors include: A cable that is out of specification (either too long, the wrong type, or defective) A bad network interface card (NIC) card (with physical problems or driver problems) A port duplex misconfiguration is a common cause of the errors because of failures to negotiate the speed and duplex properly between two directly connected devices (for example, a NIC that connects to a switch). Only half-duplex connections should ever have collisions in a LAN. Because of the carrier sense multiple access (CSMA) nature of Ethernet, collisions are normal for half duplex, as long as the collisions do not exceed a small percentage of traffic.

• Question 819:

  Refer to the exhibit.

  

  Object tracking has been configured for VRRP-enabled routers Edge-01 and Edge-02 Which commands cause Edge-02 to preempt Edge-01 in the event that interface G0/0 goes down on Edge-01?

  A. Edge-01(config)#interface G0/1 Edge-01(config-if)#vrrp 10 track 10 decrement 30

  B. Edge-02(config)#interface G0/1 Edge-02(config-if)#vrrp 10 track 10 decrement 30

  C. Edge-02(config)#interface G0/1 Edge-02(config-if)#vrrp 10 track 10 decrement 10

  D. Edge-01(config)#interface G0/1 Edge-01(config-if)#vrrp 10 track 10 decrement 10

  Correct Answer: A

• Question 820:

  What happens when a FlexConnect AP changes to standalone mode?

  A. All controller-dependent activities stop working except the DFS.

  B. All client roaming continues to work

  C. Only clients on central switching WLANs stay connected.

  D. All clients on an WLANs are disconnected

  Correct Answer: A

  When a FlexConnect access point enters standalone mode, it disassociates all clients that are on centrally switched WLANs. [ not all clients, locally switched WLAN clients stay connected]

  Controller-dependent activities, such as network access control (NAC) and web authentication (guest access), are disabled, and the access point does not send any intrusion detection system (IDS) reports to the controller.

  Most radio resource management (RRM) features (such as neighbor discovery; noise, interference, load, and coverage measurements; use of the neighbor list; and rogue containment and detection) are disabled. However, a FlexConnect access point supports dynamic frequency selection in standalone mode. https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-2/configuration/guide/cg/cg_flexconnect.html
