Cisco Designing with Cisco Network Programmability for ACI

1.

For which ACI constructs are health scores calculated?

bridge domains service graphs contracts filters service device clusters

2.

Which option is an ideal environment in which to deploy ACI?

WAN edge virtual storage farm disaster recovery site enterprise core

3.

Which description of OpFlex is true?

a proprietary protocol that is used for communication between ACI spine and leaf switches a Cisco protocol that is used between third-party orchestration tools and Cisco APIC an open and extensible policy protocol for transferring policy between a network policy controller andany device an open protocol that is used between virtual machine managers and ACI leaf switches to transferVXLAN-encapsulated packets

4.

Which statement about OpenStack and ACI is true?

Integration can leverage a Cisco APIC plug-in or a Group Policy plug-in. The Nova ML2 plug-in maps APIs into the ACI policy model. The Cisco APIC driver communicates northbound using the OpFlex plug-in. The Cisco APIC driver is used in place of an OVS driver to communicate to the virtual machinemanagers.

5.

Which three features or protocols can be used to integrate ACI into existing management tools? (Choose three.)

SNMP RESTful APIs Syslog OSPF CallHome

6.

You have an application named "E_commerce" in tenant "Production", which is composed of three tiers of servers (web, app, and DB). Each tier sits in a different EPG (epgWeb, epgApp, and epgDB). Which action should be performed first to measure the performance or packet loss of this application?

Check the health score of the application profile "E_commerce". Check the faults of the application profile "E_commerce". Configure a troubleshooting policy for on-demand atomic counters for epgWeb-to-epgApp traffic andepgApp-to-epgDB traffic. Configure a monitoring policy for each of the EPGs of the "E_commerce" application.

7.

Which statement about the programming model and APIs available to automate network functions within is true?

You can leverage a custom-built GUI that sends HTTPS calls. Advanced orchestration tools like Cisco Intelligent Automation for Cloud or Cisco UCS Director areavailable for end-to-end provisioning of compute and network resources using the open OpFlex
protocol. Every configurable element in ACI is part of the object tree known as the software development kit. You can modify configurations with HTTP DELETE calls and retrieve information with HTTP POSTcalls. You can perform a CLI-based configuration from your desktop to the controller using cURL.

8.

Which statement about the role of a spine switch is true?

It connects leaf devices. It connects spine devices It connects Cisco APICs. It connects hosts. It connects external routers.

9.

Which type of ACI switch provides Layer 3 connections to outside networks?

border leaf devices leaf devices spine devices service leaf devices

10.

Which statement about the infrastructure requirements for an ACI fabric is true?

Hypervisors that connect to the ACI fabric must support the Cisco Discovery Protocol so that ACI can discover the presence of virtualized hosts and deploy policies to the ports on which a virtualized host is
present. The Cisco Nexus 9336PQ form factor is well suited for large enterprise ACI deployments because itprovides 288 40 Gigabit Ethernet ports at the spine. Leaf and spine switches can connect at 40 Gbps with multimode fiber by using the Cisco 40 Gbpsshort-reach bidirectional QSFP optics modules, which do not require new cabling. The Cisco ACI fabric uses an overlay, based on MPLS VPN, to virtualize the physical infrastructure.This overlay maps the tenant endpoint addresses to the location of the endpoint using the tunnel
endpoint.
