• Question 94:

  A Cisco ACI environment is configured to integrate with a vCenter environment using the VMM domain name west_coast_VMM. Within the ACI environment, only tenant west_coast has EPGs associated with west_coast_VMM. This deployment is new, so these EPGs currently do not have any members. A systems engineer is setting up vCenter, creates a VDS named west-coast-VMM, and deletes the VDS named west_coast_VMM. The systems engineer creates the necessary port groups that correspond with the EPGs, but when VMs are connected to the port groups, they cannot ping their gateway. Which action establishes connectivity?

  A. Associate the EPGs to west-coast-VMM.
  B. Rename the VDS to west_coast_VMM.
  C. Use the EPG encap-VLAN on the port groups.
  D. Disconnect Cisco APIC connectivity from vCenter.
  B. Rename the VDS to west_coast_VMM.

• Question 95:

  Refer to the exhibit.

  

  A Cisco ACI fabric must allow any subnet to access the ACI fabric nodes. Which set of actions meets this requirement?

  A. Provide OOB_CTR to ExtAccess_to_OOBMgmtNetwork. Consume OOB_CTR from default EPG. Add subnet 0.0.0.0/0 under default EPG.
  B. Consume OOB_CTR from ExtAccess_to_OOBMgmtNetwork. Provide OOB_CTR to default EPG. Add subnet 0.0.0.0/0 under default EPG.
  C. Consume OOB_CTR from ExtAccess_to_OOBMgmtNetwork. Provide OOB_CTR to default EPG. Add subnet 0.0.0.0/0 under ExtAccess_to_OOBMgmtNetwork.
  D. Provide OOB_CTR to ExtAccess_to_OOBMgmtNetwork. Consume OOB_CTR from default EPG. Add subnet 0.0.0.0/0 under ExtAccess to OOBMamtNetwork.
  C. Consume OOB_CTR from ExtAccess_to_OOBMgmtNetwork. Provide OOB_CTR to default EPG. Add subnet 0.0.0.0/0 under ExtAccess_to_OOBMgmtNetwork.

• Question 96:

  Refer to the exhibit.

  

  The EPG-100 must be extended to the vCenter as a port group with a tagged VLAN ID of 100. Which set of actions accomplishes this goal?

  A. 1. Define a static VLAN range (from 100-200) under a VLAN pool that is associated with the dc1vcdev domain. 2. Associate the dc1vcdev domain with EPG and select these settings: Untagged VLAN Access: unselected VLAN Mode: Static with Encap: 100
  B. 1. Define a static VLAN range (from 100-200) under a VLAN pool that is associated with the dc1vcdev domain. 2. Associate the dc2vcdev domain with EPG and select these settings: Untagged VLAN Access: selected VLAN Mode: Static with Encap: 100
  C. 1. Define a dynamic VLAN range (from 100-200) under a VLAN pool that is associated with the del vdev domain. 2. Associate the dc1vcdev domain with EPG and select these settings: Untagged VLAN Access: unselected VLAN Mode: Static with Encap: 100
  D. 1. Define a dynamic VLAN range (from 100-200) under a VLAN pool that is associated with the dc1vdev domain. 2. Associate the dc2vcdev domain with EPG and select these settings: Untagged VLAN Access: selected VLAN Mode: Static with Encap: 100
  A. 1. Define a static VLAN range (from 100-200) under a VLAN pool that is associated with the dc1vcdev domain. 2. Associate the dc1vcdev domain with EPG and select these settings: Untagged VLAN Access: unselected VLAN Mode: Static with Encap: 100

• Question 97:

  An engineer must connect Cisco ACI fabric using Layer 2 with external third-party switches. The third-party switches are configured using 802.1s protocol. Which two constructs are required to complete the task? (Choose two.)

  A. spanning tree policy for mapping MST instances to VLANs
  B. MCP policy with PDU per VLAN enabled
  C. MCP instance policy with administrative state disabled
  D. dedicated EPG for native VLAN
  E. static binding of native VLAN in all existing EPGs
  A. spanning tree policy for mapping MST instances to VLANs
  D. dedicated EPG for native VLAN

  ---

  Explanation/Reference:

  MST (IEEE 802.1s), BPDU frames do not carry a VLAN tag, and the BPDUs are sent over the native VLAN. Typically, the native VLAN is not used to carry data traffic, and the native VLAN may not be configured for data traffic on the Cisco ACI fabric. As a result, to help ensure that MST BPDUs are flooded to the desired ports, the user must create an EPG (an MST EPG) for VLAN 1 as native VLAN to carry the BPDUs. This EPG connects to the external switches that run MST.

  In addition, the administrator must configure the mapping of MST instances to VLANs to define which MAC address table must be flushed when a Topology Change Notification (TCN) occurs. When a TCN event occurs on the external Layer 2 network, this TCN reaches the leafs to which it connects via the MST EPG, and flushes the local endpoint information associated with these VLANs on these leafs; as result, these entries are removed from the spine-proxy mapping database.
