Question #11

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?
  1. A
    MAC pinning
  2. B
    MAC binding
  3. C
    LACP passive
  4. D
    LACP active

Correct Answer:
A

Question #12
A host that is connected to a Cisco ACI fabric leaf switch sends an ARP request. Which transmission method does the ingress switch use to send the ARP requests?
  1. A
    anycast
  2. B
    broadcast
  3. C
    multicast
  4. D
    unicast

Question #13
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?
  1. A
    Enable the enforce endpoint check and set the Rouge EP detection interval
  2. B
    Enable the rogue endpoint and set the Error Disabled Recovery Policy
  3. C
    Enable the remote endpoint limit and set the Interface override
  4. D
    Enable reverse path forwarding and set the Hold Interval

Correct Answer:
B

Question #14
An engineer implements the Cisco ACI solution and needs to confirm that the leaf switch correctly learns the remote endpoint MAC. Which information must be included in the VXLAN packet that is received from the Cisco ACI spine for the Cisco ACI leaf to learn MAC as a remote endpoint?
  1. A
    VRF
  2. B
    application profile
  3. C
    bridge domain
  4. D
    EPG

Correct Answer:
C

Question #15
Which action reduces the impact on workload when migrating from the existing Cisco NX-OS VXLAN network infrastructure to the Cisco ACI fabric?
  1. A
    Disable bridge domain unicast routing while a default gateway is in VXLAN infrastructure
  2. B
    Set the default gateway in the Cisco ACI and VXLAN fabrics
  3. C
    Use ACI spines for the Cisco ACI and VXLAN fabrics
  4. D
    Configure vPC between the standalone Nexus and the Cisco ACI leaf

Correct Answer:
B
