Questions and Answers

What is a primary advantage of using a three-tier architecture for interconnecting buildings on a corporate campus?

  • It enhances scalability by allowing easy addition of new buildings through a structured hierarchy. (correct)
  • It requires fewer physical connections due to a full mesh design between buildings.
  • It simplifies network management by collapsing the core and distribution layers into a single layer.
  • It reduces the need for high-end switches at the core layer by distributing the load.

What distinguishes Top-of-Rack (ToR) switches in a spine-leaf data center architecture?

  • They exclusively manage the internal traffic within their respective racks without interfacing with spine switches.
  • They act as leaves, connecting both to servers within the rack and spine switches. (correct)
  • They serve as the primary routing interfaces for external data center traffic.
  • They directly connect to each other to form a mesh network.

You are a network administrator tasked with choosing a WAN technology that provides dedicated bandwidth and predictable latency for connecting two sites. However, high bandwidth is not a requirement. Given the need for these specific characteristics, which WAN technology would be the most appropriate choice?

  • Asynchronous Transfer Mode (ATM)
  • VPN over the Internet
  • Frame Relay
  • Point-to-Point connection using PPP (correct)

You are setting up a network for a small office with a mix of wired and wireless devices, including laptops, smartphones, and a server. To ensure all devices can communicate internally and access the Internet, which combination of network devices is most appropriate for your SOHO environment?

Study Notes

CCNA 200-301 Study Notes

Question 1: Three-Tier Architecture

  • A primary advantage of a three-tier architecture is enhanced scalability.
  • It allows for easier addition of new buildings to a structured hierarchy.
  • The architecture simplifies network management by distributing the core and distribution layers.

Question 2: Top-of-Rack (ToR) Switches

  • ToR switches in spine-leaf data center architectures act as leaves.
  • They connect to servers within the rack and spine switches.
  • ToR switches manage internal traffic within their racks without interfacing with spine switches.

Question 3: WAN Technology Selection

  • For a WAN connecting two sites with predictable latency and dedicated bandwidth, PPP (Point-to-Point Protocol) is optimal.
  • High bandwidth isn't a requirement.

Question 4: SOHO Network Device Combination

  • The most appropriate combination for a small office network with wired and wireless devices (laptops, smartphones, server) is a wireless router with built-in Ethernet ports connected to a cable modem.

Question 5: Cloud Deployment Model

  • A hybrid cloud deployment model best suits organizations needing to combine cloud flexibility with on-premises security.
  • It balances control and manageability of data with scalability of resources.
