NEW QUESTION # 74
An ACI engineer is implementing a Layer 3 out inside the Cisco ACI fabric that must meet these requirements:
The data center core switch must be connected to one of the leaf switches with a single 1G link.
The routes must be exchanged using a link-state routing protocol that supports hierarchical network design.
The data center core switch interface must be using 802.1Q tagging, and each vlan will be configured with a dedicated IP address.
Which set of steps accomplishes these goals?

A. Set up the BGP Protocol policy with the Autonomous System number of 0.
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.
B. Configure the OSPF Protocol policy with an area of 0.
Create Routed Outside object and Node Profile, selecting OSPF as the routing protocol. Build the Interface profile, selecting Routed Sub-interface and the appropriate VLAN. Configure the External Network object with a network of 0.0.0.0/0.
C. Set up the ElGRP Protocol policy with the selected Autonomous System number. Set up the Routed External Network object ana Node Profile, selecting ElGRP Create the Switch profile, selecting Port-channel and the appropriate interfaces Create the default network and associate it with the Routed Outside object.
D. Set up the ElGRP Protocol policy with the selected Autonomous System number. Create the Routed Outside object and Node Profile selecting ElGRP Configure the Interface profile selecting Routed Interface and the appropriate interfaces. Create the External Network object with a network of 0.0.0.0/0.

Answer: B

Explanation:
To implement a Layer 3 out (L3Out) inside the Cisco ACI fabric that meets the specified requirements, the following steps should be taken:
Configure the OSPF Protocol policy with an area of 0: This step involves setting up OSPF, a link-state routing protocol that supports hierarchical network design, as the routing protocol for the L3Out1.
Create Routed Outside object and Node Profile, selecting OSPF: This step involves creating a Routed Outside object and associating it with a Node Profile that specifies OSPF as the routing protocol1.
Build the Interface profile, selecting Routed Sub-interface and the appropriate VLAN: This step involves creating an Interface profile for the connection to the data center core switch, using 802.1Q tagging for VLAN separation2.
Configure the External Network object with a network of 0.0.0.0/0: This step involves setting up the External Network object to advertise routes to the rest of the network1.

NEW QUESTION # 75
A bridge domain for an EPC called "Web Servers" must be created in the Cisco APIC. The configuration must meet these requirements:
Only traffic to known Mac addresses must be allowed to reduce noice.
The multicast traffic must be limited to the ports that are participating in multicast routing.
The endpoints within the bridge domain must be kept in the endpoint table for 20 minultes without any updates.
Which set of steps configures the bridge domain that satisfies the requirements?

A. Set L2 Unknown Unicast to Hardware Proxy.
Configure L3 Unknown Multicast Flooding to Optimized Flood.
Create an Endpoint Retention Policy with a Local Endpoint Aging interval of 1200 seconds.
B. Select the ARP Flooding checkbox.
Create an Endpoint Retention Policy with a Remote Endpoint Aging Interval of 20 minutes.
Set L3 Unknown Multicast Flooding to Optimized Flooding
C. Multicast Destination Flooding should be set to Flood in BD.
Set L3 Unknown Multicast Flooding to Flood.
Select the default Endpoint Retention Policy with a Local Endpoint Aging Interval of 1200 seconds.
D. Switch L2 Unknown Unicast to Flood.
Select the default Endpoint Retention Policy and set the Local Endpoint Aging to 20 minutes.
Set Multicast Destination Flooding to Flood in Encapsulation.

Answer: A

Explanation:
To configure a bridge domain for an EPC called "Web Servers" that meets the specified requirements, the following steps should be taken:
Set L2 Unknown Unicast to Hardware Proxy: This setting ensures that only traffic to known MAC addresses is allowed, which helps to reduce noise by preventing unknown unicast flooding within the bridge domain1.
Configure L3 Unknown Multicast Flooding to Optimized Flood: This setting limits multicast traffic to the ports that are participating in multicast routing, which optimizes the delivery of multicast packets1.
Create an Endpoint Retention Policy with a Local Endpoint Aging interval of 1200 seconds (20 minutes): This policy ensures that endpoints within the bridge domain are kept in the endpoint table for 20 minutes without any updates, maintaining the stability of the network1.
By following these steps, the bridge domain will be configured to satisfy the requirements for the EPC called "Web Servers" in the Cisco APIC environment.

NEW QUESTION # 76
Which ACI import mode processes each managed object individually and skips the invalid MO?

A. best-effort
B. replace
C. atomic
D. merge

Answer: A

Explanation:
The best-effort import mode processes each managed object independently and skips only the invalid MO, allowing the remainder of the configuration to be imported successfully.

NEW QUESTION # 77
Which resolution immediacy setting allows a policy to be downloaded to the Cisco ACI leaf switch software regardless of CDP/LLDP neighborship?

A. On Demand
B. Expedite
C. Pre-Provision
D. Immediate

Answer: C

Explanation:
The Pre-Provision resolution mode causes the policy to be sent straight to the leaf's software database immediately - without waiting for CDP/LLDP discovery - whereas On-Demand holds off until a neighbor is detected.
