Network Architectures, SDN & Automation Quiz (ENCOR/CCNP)

Please enter your email:

1. Which of the following should be a characteristic of the core layer in the Cisco three-layer hierarchical model?

QoS

Emphasis on high speed

PoE

Redundant components

2. Control Plane & Data plane are local in SDN Model:

FALSE

TRUE

3. Which type of Networking model is this?

SDN Model

MPLS Model

Traditional Networking Model

Old Networking Model

4. What is the advantage of Cisco’s Fabricpath as compared to Traditional Data Center?

Traditional-vs-cisco-fabricpath-data-center

It groups devices more efficiently

All connections are 1GE which gives high data rates

STP blocks the extra redundant links & stops Layer2 loops

STP is not needed due to which it has extra Bandwidth & high speeds

5. At which of the following layers of the Cisco three-tier architecture should port security be implemented?

Core layer

Access layer

Distribution layer

Edge layer

6. What is Underlay in a Data Center design fabric?

The combination of overlays

The actual underlying devices and cables to provide IP connectivity to all nodes in the fabric

All hosts in the network

The mechanisms to create VXLAN tunnels

7. Which type of API is used between Controller & Applications in SDN Model?

Southbound and Northbound API's in SDN

CENTRALIZED API’s

NORTHBOUND API’s

SOUTHBOUND API’s

LAYERED API’s

8. Where do Access Switches normally sit?

At the distribution Layer

At the edge of the LAN

At the edge of the WAN

At the core Layer

9. Which type of solution provides lower cost & shorter time to deploy benefits?

Traditional Networks

DWDM Optical networks

SD-WAN

MPLS

10. What is the function of the distribution layer of the Three-tier architecture?

Provides an aggregation point for access switches

Provides a connection point (access) for end-user devices

Does not provides an aggregation point for access switches

Aggregates distribution switches in very large campus LANs
