質問 16
Refer to the exhibit.

A Cisco ACI fabric is newly deployed, and the security team requires more visibility of all inter-EPG traffic flows. All traffic in a VRF must be forwarded to an existing firewall pair. During fallover, the standby firewall must continue to use the same IP and MAC as the primary firewall. Drag and drop the steps from the left Into the Implementation order on the right to configure the service graph that meets the requirements. (Not all steps are used.)

質問 17
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. align the ACI QoS levels and IPN QoS policies
B. disable DSCP translation policy
C. align the custom QoS policy on the EPG site in the customer tenant
D. disable DSCP mapping on the IPN devices

正解: A

解説:
This will ensure that the Quality of Service (QoS) levels and policies within the ACI fabric and the IPN devices match, preventing packets from being delayed or dropped between pods. Additionally, it is important to align the DSCP values of the packets with the configured QoS levels to ensure that the application's requirements for latency and jitter are met.

B. MCP instance policy with administrative slate disabled
C. dedicated EPG for native VLAN
D. MCP policy with PDU per VLAN enabled
E. static binding of native VLAN in all existing EPGs

正解: A,C

質問 21
An engineer has set the VMM resolution immediacy to pre-provision in a Cisco ACI environment. No Cisco Discovery Protocol neighborship has been formed between the hypervisors and the ACI fabric leaf nodes.
How does this affect the download policies to the leaf switches?

A. Policies are downloaded when the hypervisor host is connected to the VMM VDS.
B. No policies are downloaded because there is no discovery protocol neighborship.
C. No policies are downloaded because LLDP is the only supported discovery protocol.
D. Policies are downloaded to the ACI leaf switch regardless of Cisco Discovery Protocol neighborship.

正解: D

質問 23
A customer migrates a legacy environment to Cisco ACI. A Layer 2 trunk is configured to interconnect the two environments. The customer also builds ACI fabric in an application-centric mode. Which feature should be enabled in the bridge domain to reduce instability during the migration?

A. Disable Endpoint Dataplane Learning
B. Set Multi-Destination Flooding to Flood in Encapsulation.
C. Enable Flood in Encapsulation.
D. Set Multi-Destination Flooding to Flood in BD.

正解: C

質問 24

B. Change Scope to Advertised Externally.
C. Add the L3Out for Route Profile value.
D. Leave Scope set to Private to VRF.

正解: A

質問 25
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 4094
D. from leaf ports tagged as VLAN 1

質問 26
Refer to the exhibit.

Refer to the exhibit. An engineer must allow IP mobility between Site1 and Site2 in a Cisco ACI Multi-Site orchestrator. The design must meet these requirements:
A disaster recovery (DR) solution must exist between the sites that do not require vMotion support.
The application must be started at a DR site without having to re-IP the application servers.
