   A customer creates Layer 3 connectivity to the outside network. However, only border leaf switches start receiving destination updates to other networks from the newly created L3Out. The updates must also be propagated to other Cisco ACI leaf switches. The L3Out is linked with the EPGs via a contract. Which action must be taken in the pod policy group to accomplish this goal?

   • AApply a BGP route reflector policy.
   • BEnable a COOP policy.
   • CConfigure an IS-IS policy.
   • DImplement an access management policy.

   A network administrator configures AAA inside the Cisco ACI fabric. The authentication goes through the local users if the TACACS+ server is not reachable. If the Cisco APIC is out of the cluster, the access must be granted through the fallback domain. Which configuration set meets these requirements?

   • APing Check: True - Default Authentication Realm: Local Fallback Check: True
   • BPing Check: True - Default Authentication Realm: TACACS+ Fallback Check: False
   • CPing Check: False - Default Authentication Realm: Local Fallback Check: False
   • DPing Check: False - Default Authentication Realm: TACACS+ Fallback Check: True

5. Question 125 · 340 in bank

   A Cisco ACI environment consists of multiple silent hosts that are often relocated between leaf switches. When the host is relocated, the bridge domain takes more than a few seconds to relearn the host’s new location. The requirement is to minimize the relocation impact and make the ACI fabric relearn the new location of the host faster. Which action must be taken to meet these requirements?

   • ASet Unicast Routing to Enabled.
   • BConfigure ARP Flooding to Enabled.
   • CSet L2 Unknown Unicast to Hardware Proxy.
   • DConfigure IP Data-Plane Learning to No.

7. Question 127 · 340 in bank

   A customer must upgrade the Cisco ACI fabric to use a feature from the new code release. However, there is no direct path from the current release to the desired one. Based on the Cisco APIC Upgrade/Downgrade Support Matrix, the administrator must go through one intermediate release. Which set of steps must be taken to upgrade the fabric to the new release?

   • A1. Upgrade the APICs to an interim release. 2. Upgrade the switches to an interim release. 3. Upgrade the APICs to the targeted release. 4. Upgrade the leaf and spine switches to the targeted release.
   • B1. Upgrade the APICs to an interim release and then switches to an interim release. 2. When all switches are operational, upgrade leaf switches to the targeted release. 3. Upgrade the spine switches to the targeted release. 4. Upgrade the APICs to the targeted release.
   • C1. Upgrade the APICs to an interim release. 2. Upgrade the leaf switches directly to the targeted release. 3. Upgrade the spine switches directly to the targeted release. 4. Upgrade the APICs to the targeted release.
   • D1. Upgrade the APICs directly to the targeted release. 2. Upgrade the switches to an interim release. 3. When all switches are operational, upgrade the leaf switches to the targeted release. 4. Upgrade the spine switches to the targeted release.

10. Question 130 · 340 in bank

    A network engineer configures the Cisco ACI fabric to connect to vCenter with these requirements: • Port groups must be automatically created on the distributed virtual switch. • Port groups must use the VLAN allocation in the range between 20-30. • The deployment must optimize the CAM space on the leaf switches. Which set of actions meets these criteria?

    • ACreate a dynamic VLAN pool with the VLAN range of 20-30. Create a VMM domain and associate it with the VLAN pool. Create the EPG and associate the domain. Set the deployment immediacy to On Demand.
    • BCreate a dynamic VLAN pool with the VLAN range of 20-30. Create a physical domain and associate it with the VLAN pool. Create the EPG and associate the domain. Set the deployment immediacy to On Demand.
    • CCreate a static VLAN pool with the VLAN range of 20-30. Create a physical domain and associate it with the VLAN pool. Create the EPG and associate the domain. Set the deployment immediacy to Immediate.
    • DCreate a static VLAN pool with the VLAN range of 20-30. Create a VMM domain and associate it with the VLAN pool. Create the EPG and associate the domain. Set the deployment immediacy to Immediate.
