Cisco Application Centric Infrastructure for Field Engineers Exam

Question No: 11

How are VLAN tags used in an ACI fabric?

  1. To group traffic in Layer 3 IP subnet.

  2. To group traffic, in Layer 2 broadcast domains.

  3. Only for traffic classification.

  4. Only for reporting purposes.

Answer: B

Question No: 12

Which two optionsdescribe information that is includedin the VXLANVNIDtoidentify forwardinginformationbetween theingress nodes?(Choose two)

  1. APIC that set the VXLAN VNID.

  2. Egress node that set the VXLAN VNID.

  3. VRF context to which the packet belongs.

  4. EPG from which the frame is sourcedand the bridge domain to which this packet is forwarded.

  5. List of spine and leaf nodesthrough which the packet flow.

Answer: C,D

Question No: 13

Where in the APICGUI is VMM domain created?

  1. VM networking gt; inventory

  2. Fabric gt; Access policies

  3. Tenantsgt; Common

  4. VM networking gt; policies

Answer: D

Explanation: In the APIC GUI click on VM Networking and select the Policies sub-tab Reference:http://www.virtualizationadmin.com/articles-tutorials/vmware-esx-and-vsphere- articles/general/cisco-aci-configuring-vmware-integration-apic.html

Question No: 14

How are endpoint location and identity mapping learned in an ACI fabric?

  1. Leaf nodes report endpoint addresses to the ARC using COOP.

  2. Learning occurs through APIC mapping, VMM mapping, DHCP forwarding, ARP/GARPlearning,and dataplanelearning.

  3. VMM reports virtual machine creation to spine and leaf nodes.

  4. Addresses of all hosts that are attached to the ACI fabric are programmed through the API.

Answer: B Reference:http://wenku.baidu.com/view/04e2b1afba0d4a7302763a63.html?re=viewSlide 54

Question No: 15

  1. Spine nodes

  2. Leaf nodes

  3. APICs

  4. ACI APIs

Answer: C

Explanation: Cisco ACI fabric supports discovery, boot, inventory, and systems maintenance processes through Cisco APIC Reference:http://www.slideshare.net/CiscoIndia/social-defined-networkingslide 57

Question No: 16

Which logical separator is applied to trafficadministration visibilityand other operational aspects of the ACI fabric?

  1. endpoint group

  2. application network policy

  3. Layer 2 through Layer 7 network policies of the application.

  4. Tenant

  5. contract

Answer: D

Explanation: Tenant – Logical separator for: Customer, BU, group etc. separates traffic, admin, visibility, etc.

Question No: 17

Which two tables are stored on the leaf switch of an ACI fabric? (Choose two.)

  1. proxy station table

  2. local station table

  3. tenant station table

  4. global station table

Answer: B,D

Explanation: When the ingress leaf switch receives the frame, it learns the source MAC and source IP and programs them into the local station table. The leaf switch derives the source EPG based on the VLAN ID or VXLAN VNID. The MAC and IP addresses in the local station table also contain the EPG information and they can be used to derive EPG information for the subsequent packets.

When a leaf switch receives a frame from the host it needs to determine whether the destination IP is inside the fabric or outside the fabric. If the destination IP matches with any /32 host route entry in the global station table, it means the destination is an endpoint inside the fabric and the leave switch already learned the endpoint.



Question No: 18

Which option lists the endpoint groups that are supported in an ACIfabric?

  1. Bridge domain, VTEPs, IP subnets, virtual ports, and physical ports.

  2. Bridge domain, VMM, virtual ports, VXLAN, and NVGRE.

  3. VLANs, IP subnets, physical ports, VXLAN, and NVGRE.

  4. VLANs, virtual ports, physical ports, VXLAN,and NVGRE.

Answer: D Explanation:

Endpoint groups (EPGs) group servers or services with similar policy requirements. For example, SharePoint has three tiers that require different behavior on the network: web, application, and database. All SharePoint database servers belong to the same database EPG. Each device inside of an EPG is an individual endpoint. There are several ways to group endpoints to EPGs, which include identifiers like VLAN, VXLAN, and NVGRE tags; physical ports or leaves; and virtual ports using VMware integration. Each EPG is associated to one bridge domain, which should contain the default gateways required by all endpoints in the group.

Question No: 19

What are the four aspects of an endpoint group contract?

  1. subject, filter, action, ports

  2. subject action, path, label

  3. subject, filter, action, label

  4. subject, filter, path, action

Answer: C

Question No: 20

Which two events occur on the ACI fabric in the eventof a downlink failure on one vPC peerswhen all local member ports are down?(Choose two)

  1. The vPC reconfigures using the secondary peer link that is associated with the endpoints and a new VTEP entry is created.

  2. A bounce entry is created for the endpoints that are reachable via the port channel that points to the VTEPofthe peers.

  3. The ACI fabric rediscoversthe vPC peersand re-establishescommunicationbetween the endpoint and the leaf switch.

  4. All MAC-to-leaf bindings for the specific vPC are removed from the COOP database and the spine proxy.

  5. The APIC removes the associated leaf switch from inventory and rediscovers the fabric.
