Question #1

Refer to the exhibit. An engineer configures the Cisco ACI fabric for VMM integration with ESXi servers that are to be connected to the ACI leaves.

A. LB Mode: Destination IP Address and TCP/UDP Port

B. LACP Mode: LACP Active

C. LB Mode: Source and Destination MAC Address

D. LB Mode: Source IP Address and TCP/UDP Port

E. LACP Mode: LACP Standby

Question #3

An engineer discovered an outage on the mgmt0 port of Leaf113 and Leaf114. Both leaf switches were recently registered in the fabric and have health scores of 100. The engineer discovers there is no IP address assigned to the mgmt0 interface of the switches. Which action resolves the outage?

Question #5

A situation causes a fault to be raised on the APIC. The ACI administrator does not want that fault to be raised because it is not directly relevant to the environment. Which action should the administrator take to prevent the fault from appearing?

A. Under System -> Faults, right-click on the fault and select Acknowledge Fault so that acknowledged faults will immediately disappear.

B. Create a new global health score policy that ignores specific faults as identified by their unique fault code.

C. Under System -> Faults, right-click on the fault and select Ignore Fault to create a fault severity assignment policy that hides the fault.

D. Create a stats threshold policy with both rising and falling thresholds defined so that the critical severity threshold matches the squelched threshold.

Question #7

A Cisco ACI endpoint group must have its gateway address migrated out of the ACI fabric. An engineer configures EPG-TEST with a static port binding and configures the encap VLAN with the required VLAN. Which configuration set must be used on the bridge domain to meet these requirements?

A. L2 Unknown Unicast: Hardware Proxy
Unicast Routing: Disabled
ARP Flooding: Disabled

B. L2 Unknown Unicast: Flood
Unicast Routing: Enabled
ARP Flooding: Enabled

Question #8

A network engineer is implementing a Layer 3 Out in the Cisco ACI fabric. The data center core switches must connect to a pair of leaf switches and exchange routes via a routing protocol. In addition, the implementation must meet these criteria:
- The external switch interface must use 802.1Q tagging.
- Access to the Internet for the ACI fabric must be the L3Out.
- The L3Out must use a routing protocol that has rapid convergence time and low CPU usage.
Which configuration set meets these requirements?

A. Implement the EIGRP Protocol policy with the selected Autonomous System number.
Create Routed Outside object and Node Profile and select EIGRP as the routing protocol.
Build the Interface profile and select SVI and the appropriate VPC.
Configure the External Network object with a network of 0.0.0.0/0.

B. Configure the BGP Protocol policy with the appropriate Autonomous System number.
Configure an Interface policy and an External Bridged Domain.
Create an External Bridged Network and use the configured VLAN pool.
Build the Leaf profile and select the Routed sub-interface with the appropriate VLAN.

C. Configure the OSPF Protocol policy with an area of 0.
Set up the Routed External Network object and Node Profile and select OSPF.
Create the Switch profile and select VPC with the appropriate interfaces.
Create the default network and associate it with the Routed Outside object.

D. Implement the IS-IS Protocol policy with the selected Autonomous System number.
Create the Routed Outside object and Node Profile and select IS-IS.
Configure the Interface profile and select the Routed Interface with the appropriate interfaces.
Create the External Network object.

Question #9

An engineer is implementing Cisco ACI at a large platform-as-a-service provider using APIC controllers, 9396PX leaf switches, and 9336PQ spine switches. The leaf switch ports are configured as IEEE 802.1p ports. Where does the traffic exit from the EPG in IEEE 802.1p mode in this configuration?

A. from leaf ports untagged

B. from leaf ports tagged as VLAN 0

C. from leaf ports tagged as VLAN 1

D. from leaf ports tagged as VLAN 4094

Question #10

Refer to the exhibit. Cisco ACI fabric is connected to a Cisco Catalyst 3850 Series Switch using EBGP. Server 2 is unable to communicate with Server 1. Leaf-2 fails to learn the external subnet
10.2.2.0/24 and other external subnets from other L3Outs. Which configuration ensures that the networks from Leaf-2 are learned by the external network?

A. Configure 10.2.2.0/24 under the external EPG of the L3Out.

B. Implement the bridge domain to advertise the bridge domain subnet.

C. Implement a contract between the Server 2 EPG and the L3Out.

D. Configure Spine-1 as the MP-BGP route reflector.

Question #11

In a Cisco ACI fabric, an endpoint moves between two leaf switches during a virtual machine migration. Which action does Cisco ACI take to minimize the impact to traffic during this event?

A. A new leaf switch updates a COOP database on the spine, which causes the old leaf switch to install a bounce entry.

B. A new leaf switch floods GARP to every other leaf switch in the fabric, which advertises a new endpoint location to the fabric.

C. A new leaf switch sends a COOP message directly to the old leaf switch to update it with new information about the endpoint move.

D. A new leaf switch sends a COOP message to the Cisco APIC cluster to populate a new location of the endpoint.
