• Question 62:

  DRAG DROP

  An engineer deploys a Cisco ACI Multi-Site Orchestrator for the first time. Drag and drop the actions from the left into the steps on the right to add a site and deploy new Cisco ACI objects to the fabric. Not all actions are used.

  Select and Place:

  

  

• Question 63:

  DRAG DROP

  Drag and drop the tenant implementation designs from the left onto the outcomes of the design when a greenfield Cisco ACI fabric is deployed on the right.

  Select and Place:

  

  

• Question 64:

  Refer to the exhibit.

  

  An engineer must allow IP mobility between Site1 and Site2 in a Cisco ACI Multi-Site orchestrator. The design must meet these requirements:

  A disaster recovery (DR) solution must exist between the sites that do not require vMotion support.

  The application must be started at a DR site without having to re-IP the application servers.

  The solution must avoid any broadcast storms between the sites.

  Which two actions meet these criteria? (Choose two.)

  A. Deploy a local EPG for Site1 and Site2.
  B. Define a unique bridge domain subnet per site.
  C. Configure STP between Cisco ACI fabrics.
  D. Apply the L2 Stretch feature.
  E. Disable inter-site BUM Traffic.
  D. Apply the L2 Stretch feature.
  E. Disable inter-site BUM Traffic.

• Question 65:

  Refer to the exhibit.

  

  Server A is connected to the Cisco ACI fabric using two teamed interfaces. One interface in a team is configured as active and the other remains in standby mode. When a failover occurs and the standby interface becomes active, it uses its built-in MAC address to send traffic. Which bridge domain configuration must be applied to resolve the issue?

  A. Enable ARP flooding.
  B. Activate Limit IP Learning to Subnet.
  C. Configure Hardware proxy.
  D. Set L2 Unknown Unicast to Flood
  A. Enable ARP flooding.

• Question 66:

  Which requirement applies to migration from Cisco NX-OS mode to Cisco ACI mode with Cisco Nexus 9000 Series Switches?

  A. Pre-existing vPC topology must be removed before the migration is started.
  B. A permit-all contract must be used for traffic that flows inside the data center.
  C. Pre-existing FCoE must be removed from the Nexus devices.
  D. A minimum of five Cisco APIC appliances must be used in the data center network.
  C. Pre-existing FCoE must be removed from the Nexus devices.

• Question 67:

  Refer to the exhibit.

  

  New e-commerce software is deployed on Cisco ACI fabric. The environment must meet these requirements:

  The overall number of contracts must be reduced by reusing the existing contracts within a VRF when possible.

  The e-commerce software must communicate only with software EPGs that are part of the same ANP.

  The e-commerce software must be prevented from communicating with applications in different ANPs.

  Which scope must be selected to meet these requirements?

  A. Tenant
  B. Global
  C. Endpoint Group
  D. Application Profile
  D. Application Profile

• Question 68:

  A customer is deploying a new application across two ACI pods that is sensitive to latency and jitter. The application sets the DSCP values of packets to AF31 and CS6, respectively. Which configuration changes must be made on the APIC to support the new application and prevent packets from being delayed or dropped between pods?

  A. disable DSCP translation policy
  B. align the ACI QoS levels and IPN QoS policies
  C. disable DSCP mapping on the IPN devices
  D. align the custom QoS policy on the EPG site in the customer tenant
  B. align the ACI QoS levels and IPN QoS policies

• Question 69:

  Which two components must be configured as stretched to establish intra-VRF communication between two EPGs that are deployed in different sites and different bridge domains? (Choose two.)

  A. contract
  B. tenant
  C. application profile
  D. bridge domain
  E. EPG
  B. tenant
  E. EPG

• Question 70:

  The engineer notices frequent MAC and IP address moves between different leaf switch ports. Which action prevents this problem from occurring?

  A. Disable enforce subnet check.
  B. Disable IP bridge domain enforcement.
  C. Enable endpoint loop protection.
  D. Enable rogue endpoint control.
