Q

5 Basic Role in the fabric overlay

A
  1. Control Plane node - contains the settings to provide endpoint-to-location (EID-to-RLOC) mapping system for the fabric overlay
  2. Fabric border node - this fabric device connects external Layer 3 network to the SDA fabric
  3. Fabric Edge node - conneced wired endpoints to the SDA fabric
  4. Fabric WLAN controller - connect wireless and AP to the SDA Fabric
  5. Intermediate Nodes - these are intermediate routers or extended switches that do not provide any SDA fabric roles other than underlay services

Q

SD-Access fabric concepts

A
  1. Virual Network (VN) - provide virtualization at device level using VRF
  2. Host Pool - group of endpoints assigned to an IP Pool subnet in the SDA-Access fabric
  3. Scalable group - group of endpoints with similar policies
  4. Anycast gateway - provides a pervasive L3 default gateway where the same SVI is provisione on every edge node

Q

3 Main Controller subsystems

A
  1. Cisco Network Control Platform (NCP) - directly integrated into Cisco DNA that provides all the underlay and fabric automation and orchestration. uses NETCONF/YANG
  2. Cisco Network Data Platform (NDP) - is a data collection and analytics and assurance subystem that is integrated directly into Cisco DNA Centre. (Netflow - SPAN)
  3. Cisco Identity Services Engine (ISE) provide all the identity and policy services for the physical layer and network layer

Q

Two types of hypervisor

A
  1. Type 1 - hypervisor runs directly on the system hardware
  2. Type 2 - hypervisor requires a host OS
15
Q

Is an isolated environment where containerized applications run

A

container

16
Q

is a software based layer 2 switch that operates like a physical Ethernet switch

A

vSwitch

17
Q

Is a architectural framework created by the European Telecomnunications Standards Institute (ESTI) that defines standards to decouple network functions from proprietary hardware-based appliances and have them run in soft-ware on standard x86 servers

A

Network Functions Virtualization (NFV)

18
Q

Allows VNFs to have direct access to Physical PCI devices which appear and behave as if they were physically attached to VNF

A

PCI Passthrough

19
Q

is an enhancement to PCI passthrough that allows multiple VNFs to share the same pNIC.

A

SR-IOV

20
Q

Cisco solution based on the ETSI NFV architectural framework. reduces operational complexity of enterprise branch environments by running the required networking functions as network virtual functions (VNF) on standard x86 hosts.

A

Cisco Enterprise Network Functions Virtualization (ENFV)

21
Q

Cisco ENFV Solution Architecture 4 Components

A
  1. Management and Orchestration (MANO)
  2. VNFs
  3. Network Functions Virtualization Infrastructure software (NFVIS) - operating system the provides virtualisation capabilities
  4. Hardware resource
22
Q

API - often used to communicate from a network controller to its management software

A

Northbound API

23
Q

If a network operators makes a change to a switch configuration management software of the controller, those changes are pushed down to the individuals via this API

A

Southbound API

24
Q

This API use HTTP methods to gather and manipulate data

A

Representation State Transfer (REST) APIs

25
Q
