Question 2

Refer to the exhibit. A legacy data center has a group of VLANs from 10 to 20 that must be migrated to the existing Cisco ACI fabric. The fabric must be configured such that the traffic remains undisrupted in the process, and the communication is allowed between migrated endpoints and host 1. A contract called Legacy_ACI_CTR is provided by Telco_EPG, and the VLAN pool [10-100] called "Physical_VLAN_Po" is configured. Which two actions must be taken to meet these requirements? (Choose two.)

A. Consume contract Legacy_ACI_CTR by all Layer 2 external EPGs.

B. MAP VLAN pool Physical_VLAN_Po under physical domain.

C. Configure a single bridge domain to be extended over a VPC path.

D. Create 11 L2Outs using 11 different encapsulated VLANs.

E. Extend EPG Telco_EPG over the configured path binding.

A. spine switch

B. VMM switch

C. leaf switch

D. proxy spine switch

Question 4

A network engineer must integrate VMware vCenter cluster with Cisco ACI. The requirement is for the management traffic of the hypervisors and VM controllers to use the virtual switch associated with the Cisco Application Policy. The EPG called "Vmware-MGMT" with VLAN 300 has been created for this purpose. Which set of steps must be taken to complete the configuration?

A. Enable Infrastructure VLAN on AAEP used toward VMware hypervisors.
Create a static binding in the target EPG toward VMware hypervisors with VLAN 300, untagged access VLAN, and Untagged 802.1P mode.

B. Associate the target EPG with the VMM domain with default settings.
Enable Infrastructure VLAN on AAEP used toward VMware hypervisors.

C. Enable Infrastructure VLAN on AAEP used toward VMware hypervisors.
Associate the target EPG with the VMM domain with default settings.

D. Add VLAN 300 with static allocation to the VLAN POOL that is used for VMM integration.
Attach the VMM domain to the target EPG with resolution preprovision, mode static, untagged access VLAN, and Port-Encap 300.

Correct Answer: D

Question 5

Refer to the exhibit. An engineer is implementing Cisco ACI ?VMware vCenter integration for a blade server that lacks support of bonding. Which port channel mode results in "route based on originating virtual port" on the VMware VDS?

A. MAC Pinning+

B. Static Channel - Mode On

C. MAC Pinning-Physical-NIC-load

D. LACP Passive

E. LACP Active

Question 6

An engineer must adjust the time on a Cisco ACI fabric. The implementation must use a single external time server and the APIC management interfaces for the communication. Which action accomplishes this goal?

A. Create a contract in the management tenant to allow UDP port 123.

B. Set the NTP provider minimum polling interval to 1.

C. Enable the Date and Time offset state in the system settings.

D. Set the NTP provider in default Date and Time policy.

Correct Answer: D

Question 7

As part of a migration, legacy non-ACI switches must be connected to the Cisco ACI fabric. All non- ACI switches run per-VLAN RSTP. After the non-ACI switches are connected to Cisco ACI, the STP convergence caused a microloop and significant CPU spike on all switches. Which configuration on the interfaces of the external switches that face the Cisco ACI fabric resolves the problem?

A. STP type link shared

B. BPDU filtering

C. BPDU guard

D. aggressive STP timers

Correct Answer: A

Question 8

Refer to the exhibit. A Cisco ACI environment hosts two e-commerce applications. The default contract from a common tenant between different application tiers is used, and the applications work as expected. The customer wants to move to more specific contracts to prevent unwanted traffic between EPGs. A network administrator creates the app-to-db contract to meet this objective for the application and database tiers. The application EPGs must communicate only with their respective database EPGs. How should this contract be configured to meet this requirement?

A. Set the app-to-db scope to Global.

B. Implement the app-to-db as a Taboo contract.

C. Implement the app-to-db scope as VRF.

D. Set the app-to-db scope to Application Profile.

Question 9

A Cisco ACI fabric has detected EP1 with IP address 192.168.1.1 to MAC M1 on interface Eth1/1.
The fabric is designed so that when EP1 is down, a new EP2 receives the same IP address with a different MAC M2 on the same interface Eth1/1. Which two features must be enabled to meet this requirement? (Choose two.)

A. L3 Unknown Multicast Optimized Flood

B. ARP Flooding

C. GARP Based Detection

D. L2 Unknown Unicast Hardware Proxy

E. EPG Flood in Encapsulation

Question 10

When the subnet is configured on a bridge domain, on which physical devices is the gateway IP address configured?

A. only leaf switches where the bridge domain of the tenant is present

B. all leaf switches and all spine nodes

C. all border leaf nodes where the bridge domain of the tenant is present

D. only spine switches where the bridge domain of the tenant is present

Question 11

Which description regarding the initial APIC cluster discovery process is true?

A. The APIC discovers the IP address of the other APIC controllers by using Cisco Discovery Protocol.

B. The ACI fabric is discovered starting with the spine switches.

C. Every switch is assigned a unique AV by the APIC.

D. The APIC uses an internal IP address from a pool to communicate with the nodes.
