Three-Tier Network Architecture Quiz

What is the primary purpose of the distribution layer in a three-tier network architecture?

• To store data for end-users

• To manage communication between users and the core

• To connect users directly to the core

• To manage internet traffic

In the three-tier architecture, what connects users to the access tier?

• Distribution switches

• Core routers

• Access switches

• Firewalls

Which tier in the three-tier architecture is responsible for providing major services like web and database servers?

• Core

• Distribution

• Access

• Management

Which SDN plane is responsible for routing tables and switching tables?

• Management plane

• Data plane

• Application plane

• Control plane

What does the data plane handle in SDN?

• Managing device settings

• Forwarding frames and packets

• Controlling routing tables

• Setting up encryption

In SDN, which plane do network administrators use to configure and manage devices?

In a spine and leaf architecture, which devices connect directly to the spine switches?

• Core switches

• Distribution switches

• Leaf switches

• End-user devices

What is the primary advantage of the spine and leaf architecture?

• Simplifies communication between leaf switches

• Provides efficient and redundant connections

• Reduces the cost of adding new racks

• Eliminates the need for spine switches

Why don’t leaf switches connect to each other in a spine and leaf design?

• To reduce cabling costs

• To maintain a simple topology

• To ensure traffic always passes through the spine

• To avoid redundancy

• North-south traffic

• East-west traffic

• Internal traffic

• External traffic
