• Question 12:

  DRAG DROP

  A leaf receives unicast traffic that is destined to an unknown source, and spine proxy is enabled in the corresponding bridge domain. Drag and drop the Cisco ACI forwarding operations from the left into the order the operation occurs on the right.

  Select and Place:

  

  

• Question 13:

  The servers are dual-homed to Cisco ACI Leaf1001 and Leaf1002 and must be connected in active-active mode. The server NICs do not support LACP. These settings have already been configured in Cisco ACI: Interface Policy Group type: Leaf Access Port, named active-active-noLACP Three port selectors: port-1, port-2, and port-3 An AEP called active-active-noLACP has three associated EPGs: EPG-A, EPG-B, and EPG-C Which action must be taken to migrate the server ports to a different leaf switch in the event of a catastrophic failure?

  A. Enable IP Data Plane Learning.
  B. Configure failover VLANs in the VLAN pool.
  C. Enable Port Tracking under System Settings.
  D. Configure the AEP on a physical domain.
  D. Configure the AEP on a physical domain.

• Question 14:

  Refer to the exhibit.

  

  The requirement is to prefer the local PBR node and redirect the traffic to the remote pod PBR node in the case of catastrophic node failure. Which configuration meets these requirements?

  A. location-based PBR host route advertisement resilient hashing
  B. symmetric PBR location-based PBR resilient hashing
  C. symmetric PBR unidirectional PBR resilient hashing
  D. location-based PBR host route advertisement node tracking
  D. location-based PBR host route advertisement node tracking

• Question 15:

  Refer to the exhibit.

  

  An engineer is configuring a vSwitch policy in the existing Cisco ACI fabric. The requirement is for the Cisco ACI leaf to learn individual MAC addresses from the same physical port. Which vSwitch policy configuration mode must be enabled to meet this requirement?

  A. MAC pinning
  B. MAC binding
  C. LACP passive
  D. LACP active
  A. MAC pinning

• Question 16:

  

  Refer to the exhibit. Which configuration mode must be selected for the VMM vSwitch Port Channel policy to avoid MAC flapping on the Cisco UCS Fls and Cisco ACI leaf switches?

  A. LACP Passive
  B. MAC Pinning
  C. LACP Active
  D. Static Channel ?Mode On
  B. MAC Pinning

• Question 17:

  An engineer is implementing the Cisco ACI fabric but is experiencing loops detected from endpoints. When the issue was investigated, it was discovered that the packets are received with the same source IP address but from different leaf switch ports. The engineer must prevent the issue from happening in the future and make sure that the port is brought back up if it was disabled due to the loop discovered. Which set of actions must be taken to meet these requirements?

  A. Enable the enforce endpoint check and set the Rouge EP detection interval
  B. Enable the rogue endpoint and set the Error Disabled Recovery Policy
  C. Enable the remote endpoint limit and set the Interface override
  D. Enable reverse path forwarding and set the Hold Interval
  B. Enable the rogue endpoint and set the Error Disabled Recovery Policy

• Question 18:

  How is broadcast forwarded in Cisco ACI Multi-Pod after ARP flooding is enabled?

  A. For the specific bridge domain, all spines forward the broadcast frames to IPN routers
  B. Broadcast frames are forwarded inside the pod and across the IPN using the multicast address that is associated to the bridge domain
  C. Within a pod, the ingress leaf switch floods the broadcast frame on all fabric ports
  D. Ingress replication is used on the spines to forward broadcast frames in the IPN infrastructure
  B. Broadcast frames are forwarded inside the pod and across the IPN using the multicast address that is associated to the bridge domain

• Question 19:

  An engineer configures a Cisco ACI Multi-Pod for disaster recovery. Which action should be taken for the new nodes to be discoverable by the existing Cisco APICs?

  A. Enable subinterfaces with dot1q tagging on all links between the IPN routers.
  B. Configure IGMPv3 on the interfaces of IPN routers that face the Cisco ACI spine.
  C. Enable DHCP relay on all links that are connected to Cisco ACI spines on IPN devices.
  D. Configure BGP as the underlay protocol in IPN.
  C. Enable DHCP relay on all links that are connected to Cisco ACI spines on IPN devices.

• Question 20:

  

  Refer to the exhibit. A customer implements Cisco ACI Multi-Site with default MTU settings between two sites. Which configuration should be applied on the interface Eth1/10 on the ISN-1 device?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B
