Question No : 3
Which two options describe functions of the Council of Oracles Protocol? (Choose two.)

正解:

Question No : 4
To which layer of the OSI model would the ACI concepts of policy, AEP and physical and VMM domains?

正解:
Explanation: An override policy at AEP can be used to specify a different physical interface policy for a VMM domain. This policy is useful in scenarios where a hypervisor is connected to the leaf switch through an intermediate Layer 2 node, and a different policy is desired at the leaf switch and hypervisor physical ports. For example, you can configure LACP between a leaf switch and a Layer 2 node. At the same time, you can disable LACP between the hypervisor and the Layer 2 switch by disabling LACP under the AEP override policy. The layer 2 is Data link layer

Question No : 5
Which logical separator is applied to traffic administration visibility and other operational aspects of the ACI fabric?

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

Question No : 6
To which four layers of the OSI model would the ACI concepts graphs and ANPs be associated? (Choose four.)

正解:

Question No : 7
How are endpoint location and identity mapping learned in an ACI fabric?

正解:
Explanation: VMM programs (location, identity) mapping

Question No : 8
To which layer of the OSI model would the ACI concepts of EGP, BD, policy groups (VPC, PC, interfaces), and encapsulation (VLAN, VXLAN, NVGRE) map?

正解:

Question No : 9
Which two configurations must be used when configuring the ACI fabric for OSPF? (Choose two).

正解:
Explanation: ACI fabric is designed to be a stub network with current software version. User needs to keep in mind that these parameters are configurable, and applicable on a per-private network (orVRF) basis. To apply the configured OSPF timer policy as shown in Figure 11 go to the menu TenantàNetworkingà Private Networks and choose the OSPF timer policy under drop-down menu “OSPFTimers”

Question No : 10
How are VLAN tags used in an ACI fabric?

正解:

Question No : 11
Which option describes what is included in the ACI VXLAN header with which all tenant traffic within the fabric is tagged?

正解:
Explanation:
ACI Fabric decouples the tenant endpoint address - its “identifier” - from the location of that endpoint, which is defined by its “locator,” or VTEP address • Forwarding within the fabric is between VTEPs (eVXLAN tunnel endpoints) and takes advantage of an extender VXLAN header format, referred to as the eVXLAN policy header • The mapping of the internal tenant MAC or IP address to the location is performed by the VTEP, using a distributed mapping database VTEP VTEP VTEP VTEP VTEP VTEP PayloadIPeVXLANVTEP APIC

Question No : 12
Which option describes the ACI fabric information that is contained in the proxy station table?

正解:
Explanation: Proxy Station Table contains addresses of ‘all’ hosts attached to the fabric Reference: http://249459ec2cf8839ca4b82690f879103214107f979ba5105d745b.r47.cf2.rackcdn.com/ACI%20Architecture%20Details.pdf (See the table on the right on Page #25).

Question No : 13
Which two statements describe how an attachable entity profile policy enables external connectivity'? (Choose two.)

正解:
Explanation: The ACI fabric provides multiple attachment points that connect through leaf ports to various external entities such as baremetal servers, hypervisors, Layer 2 switches (for example, the Cisco UCS fabric interconnect), and Layer 3 routers (for example Cisco Nexus 7000 Series switches). These attachment points can be physical ports, port channels, or a virtual port channel (vPC) on the leaf switches.

Question No : 14
Which aspect of an endpoint group contract is optional?

正解:
Explanation: Labels, which are used optionally to group objects such as subjects and EPGs for the purpose of further defining policy enforcement

Question No : 15
Which two tables are stored on the leaf switch of an ACI fabric? (Choose two.)

正解:
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.
