Question 3

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 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 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.

Question 4

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

Question 5

An engineer has set the VMM resolution immediacy to pre-provision in a Cisco ACI environment.
No Cisco Discovery Protocol neighborship has been formed between the hypervisors and the ACI fabric leaf nodes. How does this affect the download policies to the leaf switches?

A. Policies are downloaded when the hypervisor host is connected to the VMM VDS. B. No policies are downloaded because LLDP is the only supported discovery protocol. C. Policies are downloaded to the ACI leaf switch regardless of Cisco Discovery Protocol neighborship. D. No policies are downloaded because there is no discovery protocol neighborship.

Question 6

Cisco APICs utilize sharding to provide what function for an ACI fabric?

A. It provides replication of application network policies across the APICs in the cluster B. It provides scalability and reliability to the data sets generated and processed by the Distributed Policy Repository, the endpoint registry, the Observer, and the Topology Manager C. It provides horizontal scaling ability for policy management on APICs D. It provides a method for determining which APIC will act as the master in a fabric during the election process

Question 7

Refer to the exhibit. The default route is not present in the routing tables of the Cisco ACI leaf switches. All static and direct routes are currently being redistributed and advertised.

Which action must be taken to advertise a default route on the eBGP L3Out?

A. Implement an export route map matching 0.0.0.0/0. B. Configure a static default route on the ACI node profiles with next-hop null. C. Create a Default Route Leak Policy on the L3Out. D. Enable a BGP peer prefix policy set to Always.

Question 8

Which two statements regarding ACI Multi-Site are true? (Choose two.)

A. The Inter-Site network routers should run OSPF to establish peering with the spines. B. ACI Multi-Site is a solution that allows one APIC cluster to manage multiple ACI sites. C. ACI Multi-Site is a solution that supports a dedicated APIC cluster per site. D. Routers in the Inter-Site network must run OSPF, DHCP relay, and MP-BGP. E. The Multi-Site orchestrator must be directly attached to one ACI leaf.

Question 9

When does the Cisco ACI leaf learn a source IP or MAC as a remote endpoint?

A. When VXLAN traffic arrives on a leaf fabric port from the spine and outer source IP is in the bridge domain subnets range. B. When VXLAN traffic arrives on a leaf fabric port from the spine and inner source IP is in the Layer
3 Out EPG subnet range. C. When VXLAN traffic arrives on a leaf fabric port from the spine and inner source IP is in the bridge domain subnets range. D. When VXLAN traffic arrives on a leaf fabric port from the spine and outer source IP is in the Layer
3 Out EPG subnet range.
