Implementing Cisco Application Centric Infrastructure - Advanced (DCACIA) Questions and Answers

Question 1

Which action reduces the impact on workload when migrating from the existing Cisco NX-OS VXLAN network infrastructure to the Cisco ACI fabric?

Options:

A.

Disable bridge domain unicast routing while a default gateway is in VXLAN infrastructure

B.

Set the default gateway in the Cisco ACI and VXLAN fabrics

C.

Use ACI spines for the Cisco ACI and VXLAN fabrics

D.

Configure vPC between the standalone Nexus and the Cisco ACI leaf

Question 2

Refer to the exhibit.

What must be configured in the service graph to redirect HTTP traffic between the EPG client and EPG server to go through the Cisco ASA firewall?

Options:

A.

contract filter to allow ARP and HTTP

B.

precise filter to allow only HTTP traffic

C.

contract with no filter

D.

permit-all contract filter

Question 3

A host that is connected to a Cisco ACI fabric leaf switch sends an ARP request. Which transmission method does the ingress switch use to send the ARP requests?

Options:

A.

anycast

B.

broadcast

C.

multicast

D.

unicast

Question 4

In a Cisco ACI Multi-Site fabric, the Inter-Site BUM Traffic Allow option is enabled in a specific stretched bridge domain. What is used to forward BUM traffic to all endpoints in the same broadcast domain?

Options:

A.

ingress replication on the spines in the source site

B.

egress replication on the source leaf switches

C.

egress replication on the destination leaf switches

D.

ingress replication on the spines in the destination site

Question 5

Which approach does Cisco ACI use to achieve multidestination packet forwarding between leaf switches in the same fabric?

Options:

A.

Map VXLAN VTEP to the multicast group

B.

Map VXLAN to PIM-SM protocol

C.

Map VXLAN VNI to the multicast group

D.

Map VXLAN to PIM-DM protocol

Question 6

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?

Options:

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

Question 7

Which action must be taken to connect two nonsilient servers in active/standby mode to two ACI leaves?

Options:

A.

Implement a virtual PortChannel on ACI leaves

B.

Enable ARP flooding for the bridge domain if the MAC address of the active interface changes after NIC failover

C.

Configure ARP flooding for the bridge domain if the MAC address of the active interface stays identical

after a NIC failover

D.

Disable dataplane learning to avoid endpoint flapping

Question 8

Refer to the exhibit.

Between Cisco UCS Fls and Cisco ACI leaf switches, CDP is disabled, the LLDP is enabled, and LACP is in Active mode. Which two discovery protocols and load-balancing mechanism combinations can be implemented for the DVS? (Choose two.)

Options:

A.

CDP enabled, LLDP disabled, and LACP Active

B.

CDP disabled, LLDP enabled, and MAC Pinning

C.

CDP enabled, LLDP disabled, and MAC Pinning

D.

CDP enabled, LLDP enabled, and LACP Active

E.

CDP enabled, LLDP disabled, and LACP Passive

F.

CDP disabled, LLDP enabled, and LACP Passive

Question 9

What are two characteristics of Cisco ACI and Spanning Tree Protocol interaction? (Choose two.)

Options:

A.

When a TCN BPDU is received in a VLAN, Cisco ACI flushes the endpoints for the associated encapsulation.

B.

STP BPDUs are dropped due to MCP.

C.

MST BPDUs are flooded correctly in Cisco ACI fabric without additional configuration.

D.

BPDU filter and BPDU guard can be configured on Cisco ACI leaf edge ports.

E.

Cisco ACI must be configured as the STP root for all VLANs.

Question 10

Refer to the exhibit.

An engineer extends a Cisco ACI Multi-Pod setup to a Cisco ACI Multi-Site implementation. Which action allows the interconnection?

Options:

A.

Configure BIDIR-PIM in the IPN and ISN

B.

Use dedicated uplinks on Site 1 spines for ISN connections

C.

Connect all spines to the IPN and ISN

D.

Filter the advertisement of the Site 2 TEP pool into the IPN

Question 11

Which two components must be configured as stretched to establish intra-VRF communication between two EPGs that are deployed in different sites and different bridge domains? (Choose two.)

Options:

A.

contract

B.

tenant

C.

application profile

D.

bridge domain

E.

EPG
