Question 1:
An engineer is implementing a Cisco ACI environment that consists of more than 20 servers. Two of the servers support only Cisco Discovery Protocol with no order link discovery protocol. The engineer wants the servers to be discovered automatically by the Cisco ACI fabric when connected. Which action must be taken to meet this requirement?
A. Create an override policy that enables Cisco Discovery Protocol after LLDP is enabled in the default policy group.
B. Configure a higher-order interface policy that enables Cisco Discovery Protocol for the interface on the desired leaf switch.
C. Configure a lower-order policy group that enables Cisco Discovery Protocol for the interface on the desired leaf switch.
D. Create an interface profile for the interface that disables LLDP on the desired switch that is referenced by the interface policy group.
Correct Answer: A
Question 2:
What must be configured to redistribute externally learned OSPF routes within the ACI fabric?
A. Route Control Profile
B. BGP Route Reflector
C. BGP Inter-leak Route Map
D. PIM Sparse Mode
Correct Answer: B
Question 3:
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 mapping on the IPN devices
B. disable the DSCP translation policy
C. align the ACI QoS levels and IPN QoS policies
D. align the custom QoS policy on the EPG site in the customer tenant
Correct Answer: D
Question 4:
A network engineer implements an L3Out inside the Cisco ACI fabric. The engineer plans to connect a Cisco ACI leaf switch to a switch outside of the Cisco ACI fabric to exchange routes via a routing protocol. The external switch interface is configured with IP address 192.168.15.1/30. The ACI engineer wants to use a routing protocol that uses a hierarchical network design. The Cisco ACI fabric should use the L3Out to access the Internet. Which set of steps must be taken to meet these requirements?
A. Set up the BGP Protocol policy with the appropriate Autonomous System number. Create the Routed Outside object and Node profile, selecting BGP as the routing protocol. Build the Interface profile, selecting SVI and the appropriate VPC. Configure the 0.0.0.0/32 network as part of the External Network object.
B. Set up the EIGRP Protocol policy with the selected Autonomous System number. Set up the Routed External Network object and Node profile, selecting EIGRP. Create the Switch profile, selecting VPC and the appropriate interfaces. Create the default network and associate it with the Routed Outside object.
C. Set up the EIGRP Protocol policy with the selected Autonomous System number.
Configure an Interface policy and an External Bridged Domain.
Create an External Bridged Network using the configured VLAN pool.
Build the Leaf profile, selecting Routed Sub-Interface and the appropriate VLAN.
D. Configure the OSPF Protocol policy with an area of 0. Create the Routed Outside object and Node profile, selecting OSPF as the routing protocol.
Build the Interface profiles, selecting Routed Interface and the appropriate interface.
Set up the External Network object with a network of 0.0.0.0/0.
Correct Answer: D
Question 5:
Which type of port is used for in-band management within ACI fabric?
A. spine switch port
B. APIC console port
C. leaf access port
D. management port
Correct Answer: C
Question 6:
Refer to the exhibit. Which two configurations enable inter-VRF communication? (Choose two.)
A. Set the subnet scope to Shared Between VRFs.
B. Enable Advertise Externally under the subnet scope.
C. Export the contract and import it as a contract interface.
D. Change the contract scope to Tenant.
E. Change the subject scope to VRF.
Correct Answer: BC
Question 7:
An engineer must perform a Cisco ACI fabric upgrade that minimizes the impact on user traffic and allows only permitted users to perform an upgrade. Which two configuration steps should be taken to meet these requirements? (Choose two.)
A. Grant tenant-ext-admin access to a user who performs an upgrade
B. Divide Cisco APIC controllers into two or more maintenance groups
C. Combine all switches into an upgrade group
D. Grant the fabric administrator role to a user who performs an upgrade
E. Divide switches into two or more maintenance groups
Correct Answer: DE
Question 8:
An engineer is implementing a connection that represents an externally bridged network. Which two configurations are used? (Choose two.)
A. Layer 2 remote fabric
B. Layer 2 outside
C. Layers 2 internal
D. Static path binding
E. VXLAN outside
Correct Answer: AB
Question 9:
What represents the unique identifier of an ACI object?
A. universal resource identifier (URI)
B. application programming interface
C. management information tree
D. distinguished name
Correct Answer: D
Question 10:
Regarding the MTU value of MP-BGP EVPN control plane packets in Cisco ACI, which statement about communication between spine nodes in different sites is true?
A. By default, spine nodes generate 9000-byte packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 9000-bytes packets.
B. By default, spine nodes generate 1500-byte packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 1800-bytes packets.
C. By default, spine nodes generate 1500-byte packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 1500-bytes packets.
D. By default, spine nodes generate 9000-byte packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 9100-bytes packets.
Correct Answer: D
Question 11:
How is an EPG extended outside of the ACI fabric?
A. Create an external bridged network that is assigned to a leaf port.
B. Create an external routed network that is assigned to an EPG.
C. Enable unicast routing within an EPG.
D. Statically assign a VLAN ID to a leaf port in an EPG.
Correct Answer: D
Question 12:
An administrator must migrate the vSphere Management VMkernel of all ESXi hosts in the production cluster from the standard default virtual switch to a VDS that is integrated with APIC in a VMM domain. Which action must be completed in this scenario?
A. The Management VMkernel EPG resolution must be set to Pre-Provision.
B. The administrator must create an in-band VMM Management EPG before performing the migration.
C. The administrator must set the Management VMkernel BD resolution immediacy to On-Demand.
D. The VMkernel Management BD must be located under the Management Tenant.
Correct Answer: A
Question 13:
The existing network and ACI fabric have been connected to support workload migration. Servers will physically terminate at the Cisco ACI, but their gateway must stay in the existing network. The solution needs to adhere to Cisco\’s best practices. The engineer started configuring the relevant Bridge Domain and needs to complete the configuration. Which group of settings is required to meet these requirements?
A. L2 Unknown Unicast: Hardware Proxy L3 Unknown Multicast Flooding: Flood Multi-Destination Flooding: Flood in BD ARP Flooding: Enable
B. L2 Unknown Unicast: Flood L3 Unknown Multicast Flooding: Flood Multi-Destination Flooding: Flood in BD ARP Flooding: Enable

Correct Answer: B
Question 14:
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.
