DRAG DROP

An engineer must migrate servers from a legacy data center infrastructure to a Cisco ACI fabric. Drag and drop the steps from the left into the order that they must be completed on the right to ensure the least amount of downtime.

Select and Place:

What does the VXLAN source port add to the overlay packet forwarding when it uses the hash of Layer 2, Layer 3, and Layer 4 headers of the inner packet?

A. ECMP

B. TCP optimization

C. disabled fragmentation

D. jumbo frames

Refer to the exhibit. An engineer wants to avoid connectivity problems for the endpoint EP1 when it reaches an external L3Out network through the gateway 10.2.2.254/24. Which two configurations must be implemented in BD-BD2? (Choose two.)

A. Disable unicast routing

B. Enable IP data plane learning for the VRF

C. Disable ARP flooding

D. Enable ARP flooding

E. Enable unicast routing

Refer to the exhibit. Which configuration must be implemented on L3Out EBGP to advertise out of the fabric 172.16.2.0/24 network that is learned from L3Out OSPF?

A. Option A

B. Option B

C. Option C

D. Option D

An engineer designs a Cisco ACI Multi-Pod solution that requires a pair of active-standby firewalls in different pods for external connectivity. How should the firewalls be implemented?

A. PBR for routed firewalls

B. separate L3Out peerings for routed firewalls

C. routed firewall for the default gateway

D. transparent firewalls

How is broadcast forwarded in Cisco ACI Multi-Pod after ARP flooding is enabled?

A. For the specific bridge domain, all spines forward the broadcast frames to IPN routers

B. Broadcast frames are forwarded inside the pod and across the IPN using the multicast address that is associated to the bridge domain

C. Within a pod, the ingress leaf switch floods the broadcast frame on all fabric ports

D. Ingress replication is used on the spines to forward broadcast frames in the IPN infrastructure

Which firewall connection allows for the integration of service nodes in transparent mode with a Cisco ACI Multi-Pod setup?

A. active-standby mode across pods

B. active-active mode per pods for communication between internal endpoints

C. active-standby mode per pods for communication between endpoints and external networks

D. active-active mode across pods

What is a design implication for Cisco ACI using an application-centric approach?

A. Multiple VLANs and/or multiple EPGs are under one bridge domain

B. VLAN numbers are in the names of the bridge domain and EPG objects

C. One EPG is mapped to multiple bridge domains

D. One VLAN equals one EPG equals one bridge domain

An engineer is implementing the Cisco ACI fabric but is experiencing loops detected from endpoints. When the issue was investigated, it was discovered that the packets are received with the same source IP address but from different leaf switch ports. The engineer must prevent the issue from happening in the future and make sure that the port is brought back up if it was disabled due to the loop discovered. Which set of actions must be taken to meet these requirements?

A. Enable the enforce endpoint check and set the Rouge EP detection interval

B. Enable the rogue endpoint and set the Error Disabled Recovery Policy

C. Enable the remote endpoint limit and set the Interface override

D. Enable reverse path forwarding and set the Hold Interval

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 translation policy

B. align the ACI QoS levels and IPN QoS policies

C. disable DSCP mapping on the IPN devices

D. align the custom QoS policy on the EPG site in the customer tenant
