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

Please enter your email:

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

Traditional Networks

MPLS

DWDM Optical networks

SD-WAN

2. 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

STP blocks the extra redundant links & stops Layer2 loops

All connections are 1GE which gives high data rates

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

3. Which type of Networking model is this?

MPLS Model

Old Networking Model

SDN Model

Traditional Networking Model

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

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

Aggregates distribution switches in very large campus LANs

Provides an aggregation point for access switches

Does not provides an aggregation point for access switches

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

Access layer

Edge layer

Distribution layer

Core layer

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

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

The combination of overlays

All hosts in the network

The mechanisms to create VXLAN tunnels

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

FALSE

TRUE

8. Where do Access Switches normally sit?

At the edge of the WAN

At the edge of the LAN

At the distribution Layer

At the core Layer

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

Southbound and Northbound API's in SDN

SOUTHBOUND API’s

NORTHBOUND API’s

CENTRALIZED API’s

LAYERED API’s

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

Redundant components

Emphasis on high speed

PoE
