1. Question 601 · 1003 in bank

   A large campus network has deployed two wireless LAN controllers to manage the wireless network WLC1 and WLC2 have been configured as mobility peers. A client device roams from AP1 on WLC1 to AP2 on WLC2, but the controller's client interfaces are on different VLANs. How do the wireless LAN controllers handle the inter-subnet roaming?

   • AWLC1 marks the client with an anchor entry in its own database. The database entry is copied to the new controller and marked with a foreign entry on WLC2.
   • BWLC2 marks the client with an anchor entry in its own database. The database entry is copied to the new controller and marked with a foreign entry on WLC1.
   • CWLC1 marks the client with a foreign entry in its own database. The database entry is copied to the new controller and marked with an anchor entry on WLC2.
   • DWLC2 marks the client with a foreign entry in its own database. The database entry is copied to the new controller and marked with an anchor entry on WLC1.

   Show answer

   Answer: A

   Explanation

   Inter-subnet roaming is similar to inter-controller roaming in that the controllers exchange mobility messages on the client roam. However, instead of moving the client database entry to the new controller, the original controller marks the client with an “Anchor” entry in its own client database. The database entry is copied to the new controller client database and marked with a “Foreign” entry in the new controller. The roam remains transparent to the wireless client, and the client maintains its original IP address. reference: https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-3/configuration/guide/b_cg73/b_wlc-cg_chapter_01111.html

   In a Cisco Catalyst switch equipped with two supervisor modules an administrator must temporarily remove the active supervisor from the chassis to perform hardware maintenance on it. Which mechanism ensures that the active supervisor removal is not disruptive to the network operation?

   • AVRRP
   • BHSRP
   • CNSF/NSR
   • DSSO

   Show answer

   Answer: D

   Explanation

   Both C and D could be correct answers. But, gun to my head, I'm going with D. SSO is the fundamental technology that allows this. NSF requires SSO.

   Refer to the exhibit. What is the effect of introducing the sampler feature into the Flexible NetFlow configuration on the router?

   • ANetFlow updates to the collector are sent 50% less frequently.
   • BEvery second IPv4 packet is forwarded to the collector for inspection.
   • CCPU and memory utilization are reduced when compared with what is required for full NetFlow.
   • DThe resolution of sampling data increases, but it requires more performance from the router.

   Show answer

   Answer: C

   Explanation

   "Flow sampling reduces the CPU overhead of analyzing traffic with Flexible NetFlow by reducing the number of packets that are analyzed." Taken from: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fnetflow/configuration/xe-3se/3850/use-fnflow-redce-cpu.html

   Select 2

   What are two reasons why broadcast radiation is caused in the virtual machine environment? (Choose two.)

   • AvSwitch must interrupt the server CPU to process the broadcast packet.
   • BThe Layer 2 domain can be large in virtual machine environments.
   • CVirtual machines communicate primarily through broadcast mode.
   • DCommunication between vSwitch and network switch is broadcast based.
   • ECommunication between vSwitch and network switch is multicast based.

   Show answer

   Answer: AB

   Explanation

   Thinking it is A and B. Based off the reference link. Because the vswitch is software based, as broadcasts are received the vswitch must interrupt the server CPU to change contexts to enable the vswitch to process the packet. After the vswitch has determined that the packet is a broadcast, it copies the packet to all the VMNICs, which then pass the broadcast packet up the stack to process. This processing overhead can have a tangible effect on overall server performance if a single domain is hosting a large number of virtual machines

   Refer to the exhibit. An engineer has configured an IP SLA for UDP echos. Which command is needed to start the IP SLA to lest every 30 seconds and continue until stopped?

   • Aip sla schedule 100 life forever
   • Bip sla schedule 30 start-time now life forever
   • Cip sla schedule 100 start-time now life 30
   • Dip sla schedule 100 start-time now life forever

   Answer: D

   Explanation

   C is incorrect: https://www.cisco.com/c/en/us/td/docs/ios/ipsla/command/reference/sla_book/sla_02.html (Optional) Specifies the number of seconds the IP SLAs operations will actively collect information. The default is 3600 (one hour). it has to be D, because B references the wrong SLA, and A doesn't actually start it
