• Question 263:

  The Application team reports that a previously existing port group has disappeared from vCenter. An engineer confirms that the VMM domain association for the EPG is no longer present. Which action determines which user is responsible for the change?

  A. Check the EPG audit logs for the "deletion" action and compare the affected object and user.
  B. Evaluate the potential faults that are raised for that EPG.
  C. Examine the health score and drill down to an object that affects the EPG combined score.
  D. Inspect the server logs to see who was logging in to the APIC during the last few hours.
  A. Check the EPG audit logs for the "deletion" action and compare the affected object and user.

• Question 264:

  The company's Cisco ACI fabric hosts multiple customer tenants. To meet a service level agreement, the company is constantly monitoring the Cisco ACI environment. Syslog is one of the methods used for monitoring. Only events related to leaf and spine environmental information without specific customer data should be logged. To which ACI object must the configuration be applied to meet these requirements?

  A. infra tenant
  B. access policy
  C. switch profile
  D. fabric policy
  D. fabric policy

• Question 265:

  Where are STP BPDUSs flooded in Cisco ACI fabric?

  A. in the access encapsulation VLAN part of different VLAN pools
  B. in the bridge domain VLAN
  C. in the native VLAN ID
  D. in the VNID that is assigned to the FD VLAN
  D. in the VNID that is assigned to the FD VLAN

  ---

  Explanation/Reference:

  ACI floods STP Bridge Protocol Data Units (BPDUs) to the VXLAN network identifier (VNID) assigned to the FD VLAN (VNID is assigned through the VLAN pool so encapsulation has to be part of same VLAN pool to be in part of same STP domain). So in effect, it operates as an Ethernet hub when it comes to Spanning Tree. When external L2 switches are connected to an ACI leaf, they default to full-duplex operation. In the STP world, this equates to a P2P link type

• Question 266:

  An engineer is implementing a Cisco ACI data center network that includes Cisco Nexus 2000 Series 10G fabric extenders. Which physical topology is supported?

  

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

  Explanation/Reference:

  FEX ( N2K Switchs ) must be connected to one parent switch ( N9K) .

• Question 267:

  Which feature dynamically assigns or modifies the EPG association of virtual machines based on their attributes?

  A. vzAny contracts
  B. standard contracts
  C. application EPGs
  D. uSeg EPGs
  D. uSeg EPGs

  ---

  Explanation/Reference:

  Microsegmented EPGs (uSeg) works based on attribute.

• Question 268:

  A Cisco APIC is configured with RADIUS authentication as the default. The network administrator must ensure that users can access the APIC GUI with a local account if the RADIUS server is unreachable. Which action must be taken to accomplish this goal?

  A. Associate console authentication with the "RADIUS" realm
  B. Reference the "local" realm in the fallback domain
  C. Create an additional login domain that references local accounts
  D. Enable the fallback check with the default authentication domain
  B. Reference the "local" realm in the fallback domain

• Question 269:

  Which two external entities are referenced by an AEP? (Choose two.)

  A. Layer 3 domain
  B. Hypervisor
  C. VMM domain
  D. Fibre Channel switch
  E. VMware vCenter server
  A. Layer 3 domain
  C. VMM domain

• Question 270:

  When a pre-provision immediacy is used, when is the policy downloaded to the Cisco ACI leaf switch?

  A. The policy is downloaded and programmed in the hardware policy CAM when the change is implemented on the Cisco APIC.
  B. The policy is programmed in the hardware policy CAM when the policy is downloaded in the leaf software.
  C. The policy is programmed in the hardware policy CAM when the first packet is received through the data path.
  D. The policy is downloaded to the associated leaf switch software when the ESXi host is attached to a DVS.
  A. The policy is downloaded and programmed in the hardware policy CAM when the change is implemented on the Cisco APIC.
