An enterprise is designing a new campus network and wants to ensure scalability, high availability, and easy management. The design team has chosen a three-tier hierarchical architecture. Which of the following are the primary functions of the core layer in this architecture?
A
Providing high-speed switching to ensure fast transport between distribution layers
B
Aggregating access layer devices and providing policy-based connectivity
C
Ensuring fault isolation at the access layer
D
Delivering redundancy and failover capabilities to maintain network uptime
E
Connecting the enterprise network to external networks, such as the internet
Show answer and explanation
Correct answers: A, D
Explanation
The three-tier hierarchical design divides the enterprise network into core, distribution, and access layers. The core layer's primary focus is on high-speed, reliable switching and redundancy to ensure efficient data transport between distribution layers. It does not handle policy enforcement or device aggregation, which are responsibilities of the distribution layer, or external connectivity, which is typically handled by the edge layer.
A. Correct.
Correct: The core layer serves as the backbone of the network, focusing on high-speed switching and fast transport between distribution layers.
B. Incorrect.
Incorrect: Aggregating access layer devices and enforcing policies are functions of the distribution layer, not the core layer.
C. Incorrect.
Incorrect: Fault isolation is a feature of the access layer, where devices are closer to end users and localized failures can be contained.
D. Correct.
Correct: Redundancy and failover capabilities are critical functions of the core layer to ensure the network remains operational even during failures.
E. Incorrect.
Incorrect: Connecting to external networks is typically a function of the edge or border layer, not the core layer.
An enterprise network is undergoing a redesign to adopt a hierarchical campus architecture model. The network architect plans to implement modularity and scalability to improve performance and ease of troubleshooting. Which of the following design considerations align with the hierarchical campus architecture model?
A
Implementing a core layer that provides high-speed connectivity between distribution layers.
B
Collapsing the core and access layers to reduce hardware costs.
C
Designing the distribution layer for policy enforcement and inter-VLAN routing.
D
Placing end devices directly in the core layer to minimize latency.
E
Using the access layer to aggregate end devices and provide network access.
Show answer and explanation
Correct answers: A, C, E
Explanation
The hierarchical campus architecture consists of three layers: the access, distribution, and core layers. Each layer has specific roles to ensure modularity, scalability, and ease of troubleshooting. The core layer provides high-speed backbone connectivity, the distribution layer enforces policies and routes traffic, and the access layer connects end devices. This layered approach improves network performance and simplifies management.
A. Correct.
Correct. The core layer is responsible for high-speed connectivity and acts as the backbone of the hierarchical architecture.
B. Incorrect.
Incorrect. Collapsing the core and access layers contradicts the hierarchical model and reduces modularity and scalability.
C. Correct.
Correct. The distribution layer is designed for policy enforcement, inter-VLAN routing, and acting as an intermediary between the access and core layers.
D. Incorrect.
Incorrect. End devices should not be placed in the core layer as it is designed for high-speed backbone connectivity, not endpoint access.
E. Correct.
Correct. The access layer is responsible for aggregating end devices, such as PCs and IP phones, and providing them with network access.
A company is redesigning its enterprise network to ensure better scalability and simplified management. Which architecture design approach would best suit this requirement?
A
Three-tier architecture with core, distribution, and access layers.
B
Flat network design with all devices in a single broadcast domain.
C
Single-layer architecture using only access switches.
D
Hub-and-spoke topology without redundant links.
Show answer and explanation
Correct answer: A
Explanation
The three-tier architecture is the most suitable design for enterprise networks as it ensures better scalability, fault isolation, and simplified management. The core layer provides fast transport, the distribution layer handles routing and policy enforcement, and the access layer connects end devices. This hierarchical design aligns with industry best practices and supports the needs of modern enterprises.
A. Correct.
The three-tier architecture provides scalability, segregation of roles, and simplified management by dividing the network into core, distribution, and access layers. This is the industry standard for enterprise networks.
B. Incorrect.
A flat network design causes scalability issues due to large broadcast domains and difficulty in isolating faults or managing traffic. It is not suitable for modern enterprise environments.
C. Incorrect.
A single-layer architecture lacks scalability and redundancy, making it unsuitable for enterprise networks that require high availability and performance.
D. Incorrect.
Hub-and-spoke topology without redundant links would result in a lack of fault tolerance and scalability, making it impractical for most enterprise network designs.
