• Question 174:

  A Cisco ACI fabric must send a packet between two pods in a Cisco ACI Multi-Pod topology where ARP flooding is disabled within the bridge domain. How does a Cisco ACI spine switch forward ARP messages from a leaf switch in POD1 to POD2?

  A. ARP optimization is applied and sends ARP to remote anycast.
  B. The ARP message is dropped and connectivity is lost between the endpoints.
  C. A proxy ARP message is sent to destination group 225.224.0.0.
  D. An ARP Glean message is sent to multicast address 239.255.255.240.
  D. An ARP Glean message is sent to multicast address 239.255.255.240.

• Question 175:

  What is the minimum number of APICs does Cisco recommend to deploy in a production cluster?

  A. 1
  B. 3
  C. 4
  D. 5
  B. 3

• Question 176:

  A Cisco ACI fabric must be integrated with a VMware vSphere environment. One of the ESXi hosts is still disconnected from the Distributed Virtual Switch (DVS) and the VMM domain. Two EPGs have already been created and associated with the VMM domain. An engineer must prepare the ACI configuration such that: EPG contracts must be sent to ACI leaf switches before a hypervisor is attached to the DVS. EPG contracts must be pushed to leaf hardware as soon as the policy is downloaded into the leaf software.

  Which EPG configuration must be used to meet these requirements?

  A. Resolution immediacy: Pre-provision Deployment immediacy: On-Demand
  B. Resolution immediacy: Pre-provision Deployment immediacy: Immediate
  C. Resolution immediacy: On-Demand Deployment immediacy: On-Demand
  D. Resolution immediacy: On-Demand Deployment immediacy: Immediate
  B. Resolution immediacy: Pre-provision Deployment immediacy: Immediate

• Question 177:

  A company's virtualization is hosted on a Nutanix infrastructure. The company has an Application Centric Infrastructure virtual machine manager (VMM) integration with a Nutanix cluster. The existing mapping uses IP address management (IPAM) settings to enable the DHCP within Nutanix to allocate IP addresses. The company wants to change the settings of the EPG-10 VMM to EPG association and remove the DHCP functionality as it is not required.

  Which process accomplishes this goal?

  A. Shutdown remaining VMs in the EPG-10. Disable IPAM functionality on VMM to EPG association. Remove subnet association with the VMs NIC on the Nutanix cluster. Re-attach the VMs NIC back to the subnet EPG-10 on the Nutanix cluster. Power on the VMs.
  B. Shutdown remaining VMs in the EPG-10. Remove subnet association with the VMs NIC on the Nutanix cluster. Remove VMM association from EPG-10. Re-associate VMM to EPG-10 with IPAM enabled and DHCP server override. Re-attach the VMs NIC back to the subnet EPG-10 on the Nutanix cluster. Power on the VMs.
  C. Shutdown remaining VMs in the EPG-10. Remove DHCP server override option from VMM to EPG association. Remove subnet association with the VMs NIC on the Nutanix cluster. Re-attach the VMs NIC back to the subnet EPG-10 on the Nutanix cluster. Power on the VMs.
  D. Shutdown remaining VMs in the EPG-10. Remove subnet association with the VMs NIC on the Nutanix cluster. Remove VMM association from EPG-10. Re-associate VMM to EPG-10 with IPAM option disabled. Re-attach the VMs NIC back to the subnet EPG-10 on the Nutanix cluster. Power on the VMs.
  D. Shutdown remaining VMs in the EPG-10. Remove subnet association with the VMs NIC on the Nutanix cluster. Remove VMM association from EPG-10. Re-associate VMM to EPG-10 with IPAM option disabled. Re-attach the VMs NIC back to the subnet EPG-10 on the Nutanix cluster. Power on the VMs.

• Question 178:

  Refer to the exhibit.

  

  A service provider hosts applications for multiple organizations. Each organization owns a separate tenant and syslog server. The events from each tenant must be sent to the corresponding syslog server. Which action accomplishes this goal?

  A. Configure a single shared external syslog server and apply it to all of the user tenants.
  B. Configure a single shared external syslog server and apply it to the common tenant.
  C. Configure an external syslog server for each tenant and apply each of them to the related tenant.
  D. Configure an external syslog server for each tenant and apply all of them to the common tenant.
  C. Configure an external syslog server for each tenant and apply each of them to the related tenant.

• Question 179:

  An engineer created two interface protocol policies called Pol_CDP40275332 and Pol_LLDP46783451. The policies must be used together in a single policy. Which ACI object must be used?

  A. interface policy group
  B. switch policy group
  C. switch profile
  D. interface profile
  A. interface policy group

• Question 180:

  An engineer must attach an ESXi host to the Cisco ACI fabric. The host is connected to Leaf 1 and has its gateway IP address 10.10.10.254/24 configured inside the ACI fabric. A new firewall is attached to Leaf 2 and mapped to the same EPG and BD as the ESXi host. The engineer must migrate the gateway of the ESXi host to the firewall. Which configuration set accomplishes this goal?

  A. Disable unicast routing. Configure IP address 10.10.10.254/24 on the ACI BD.
  B. Disable unicast routing. Define IP address 10.10.10.254/24 on the firewall.
  C. Enable unicast routing. Configure IP address 10.10.10.254/24 on the ACI EPG.
  D. Enable unicast routing. Set IP address 10.10.10.254/24 on the firewall.
  B. Disable unicast routing. Define IP address 10.10.10.254/24 on the firewall.
