Q

What are the two subsystems for the DNAC Controller Layer?

A

Cisco Network Control Platform (NCP)
Cisco Network Data Platform (NDP)

20
Q

Cisco Network Control Platform (NCP)

A

focuses on automating and controlling the network

21
Q

Cisco Network Data Platform (NDP)

A

specializes in collecting and analyzing data to provide visibility and optimization insights

22
Q

Cisco Identity Services Engine (ISE)

A

a policy-based access control platform that secures networks by ensuring users and devices are authenticated, authorized, and compliant before accessing resources

23
Q

VXLAN (important, Brian)

A

(OVERLAY) VIrtual Extensible LAN , enables scalable creation of virtual Layer 2 networks over an existing Layer 3 infrastructure. The new Cisco OTV technology. 24 bit 2^^24 =16,777,216

24
Q

VRF (Important Brian)

A

(OVERLAY) Virtual Routing and Forwarding; allows multiple instances of a routing table to coexist on the same physical router or Layer 3 switch

25
Q

NVGRE

A

(OVERLAY) Network Virtualization using Generic Routing Encapsulation; Similar to VXLAN, Allows virtual networks to extend across geographically dispersed data centers over an IP-based infrastructure.

26
Q

OTV

A

(OVERLAY) Overlay Transprt virtualization; for extending L2 VLANS to a remote network. The old Cisco VXLAN technology.

27
Q

mVPN

A

(OVERLAY) enables the delivery of multicast traffic across a Multiprotocol Label Switching (MPLS)-based Virtual Private Network (VPN)

28
Q

An SD-Access fabric consists of four planes of operation:

A

Control plane
Data plane
Policy plane
Management plane

29
Q

LISP

A

Locator/ID Seperation Protocol; An enterprise with multiple office locations may use LISP to ensure that devices maintain a consistent EID regardless of which office they connect from. If an employee moves from one office (with one RLOC) to another

30
Q

VXLAN: what is a VEM

A

VIrtual Ethernet Module, each leaf router that runs VXLAN needs to run this

31
Q

VXLAN; VTEP

A

VXLAN tunnel Endpoint

32
Q

BUUM traffic

A

Braodcast, Unknown Unicast, Multicast

33
Q

TrustSec: SGTs

A

Scalable Group Tags

34
Q

TrustSec: SGACL’s

A

Scalable Group Access Control

35
Q

HTDB

A

HAP Table Database. It is used in the implementation of Cisco’s High Availability Protocol (HAP)

36
Q

SD-WAN; cEdge routers

A

Data plane; integrate Viptela software with Cisco IOS-XE

37
Q

SD-WAN; vManage Network Management System (NMS)

A

Management plane - provides a single GUI to configure and manage the components of the SD-WAN architecture

38
Q

SD-WAN; vBond orchestrator

A

Orchestration plane; authenticates Edge routers and vSmart controllers over a Datagram Transport Layer Security (DTLS) tunnel. needs a public IP.

39
Q

SD-WAN; vSmart controller

A

Control plane; vBond orchestrator and Edge routers must maintain DTLS connections to at least one vSmart controller. vSmart controller uses OMP to distribute routing information

40
Q

SD-WAN; vAnalytics

A

provides detailed information about the WAN infrastructure and WAN-based applications

41
Q

SD-WAN; vEdge

A

Data Plane; the original Viptela platforms running Viptela software

42
Q

SD-WAN; OMP

A

Overlay Management Protocol; acts as the core protocol for communication between the SD-WAN fabric’s edge devices and controllers, ensuring efficient route, policy, and service management
