Question No: 16

What is the function of the OpFlex protocol policy element?

  1. Stores statistical information

  2. Learns and knows every device in the network

  3. Resolves policy and configures network hardware/software

  4. Captures and stores the user intent in policy

  5. Limits device features

Answer: C

Reference: http://blogs.cisco.com/tag/opflex/ Policy Repository

The policy repository (PR) is a logically centralized entity containing the definition of all policies governing the behavior of the system. In Cisco ACI, this function is performed by the Cisco APIC or by the leaf nodes of the network fabric. The policy authority handles policy resolution requests from each policy element.

Policy Element (Policy Agent)

A policy element (PE) is a logical abstraction for a physical or virtual device that implements and enforces policy. This is where the Policy Agent describe in detail herein resides. Policy elements are responsible for requesting portions of the policy from the policy authority as new endpoints connect, disconnect, or change. Additionally, policy elements are responsible for rendering that policy from an abstract form into a concrete form that maps to their internal capabilities. This process is a local operation and can function differently on each device as long as the semantics of the policy are honored.

Endpoint Registry

The endpoint registry (ER) stores the current operation state (identity, location, etc.) of each endpoint (EP) in the system. The endpoint registry receives information about each endpoint from the local policy element and then can share it with other policy elements in the system. The endpoint registry may be physically co-located with the policy authority, but it may also be distributed in the network fabric itself. In Cisco#39;s ACI solution, the endpoint registry actually lives in a distributed database within the network itself to provide additional performance and resiliency.

Question No: 17

Answer: E

Question No: 18

Which option describes the Cisco ACI end point group?

  1. A collection of users that require the same policy

  2. A collection of switches that require the same policy

  3. A collection of business goals that require the same policy

  4. A collection of hosts/devices that require the same policy

  5. A collection of routers interfaces that require the same policy

Answer: D

Question No: 19

Which three statements about a controller based on imperative control are true? (Choose three.)

  1. User intent is captured and implemented.

  2. It uses abstract policies rather than a device-specific configuration.

  3. Knowledge of infrastructure device specific commands is needed to deploy applications.

  4. Set of device features is broad because scale is not an issue.

  5. Device features are limited.

  6. No knowledge of infrastructure device specific commands is needed to deploy applications.

  7. User intent is difficult to capture and implement.

Answer: C,E,G

Question No: 20

Which option does the Cisco ACI fabric distributed proxy mapping database map the internal tenant MAC or IP address to?

  1. Spine port

  2. VxLAN tunnel endpoint address

  3. Distinguished name

  4. IPv6 address

  5. Cisco APIC policy

Answer: B

Reference: http://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/1-x/aci- fundamentals/b_ACI-Fundamentals/b_ACI_Fundamentals_BigBook_chapter_0100.pdf

Forwarding within the fabric is between VTEPs. The mapping of the internal tenant MAC or IP address to a location is performed by the VTEP using a distributed mapping database. After a lookup is done, the VTEP sends the original data packet encapsulated in VXLAN with the Destination Address (DA) of the VTEP on the destination leaf. The packet is then de-encapsulated on the destination leaf and sent down to the receiving host. With this model, we can have a full mesh, loop-free topology without the need to use the spanning- tree protocol to prevent loops.
