2.1.9 Check Your Understanding – Clients and Servers Exam Answers
Understanding the roles of clients and servers is fundamental in networking, and this exam answers segment tests your grasp of these concepts. Below, we provide detailed answers to the “Check Your Understanding” questions, ensuring clarity and accuracy to aid your study. Each explanation is crafted to reinforce your knowledge of client-server models, their interactions, and the protocols that govern communication. Whether you’re preparing for an exam or seeking to solidify your networking skills, these answers will guide you through the essential principles with practical insights.
1. GlobalTech Solutions is planning to upgrade its data center to optimize traffic flow. They wish to improve server-to-server communication within the data center. Which type of network traffic are they focusing on?
- Peer-to-Peer
- Client-Server
- North-South
- East-West
GlobalTech Solutions is focused on East-West traffic to improve server-to-server communication within the data center. East-West traffic refers to the flow of data that moves laterally between servers, storage systems, and other networked devices within the same data center environment. This contrasts with North-South traffic, which involves data moving in and out of the data center, typically between the data center and external entities such as users accessing cloud services or remote clients.
2. SmartGrid Solutions is deploying a system to monitor and control electricity flow across its network. Which aspect is critical for their network to support real-time communications?
- Low Latency
- High Latency
- Fault Tolerance
- Scalability
Low latency is essential for real-time communications because it ensures that there is minimal delay between the transmission and reception of data. In the context of a smart grid, where decisions and adjustments to electricity flow need to be made quickly based on real-time data, low latency is crucial to ensure the system can respond promptly to changes in demand or supply, potential faults, or other critical events.
3. SecureData Co. wants to ensure their new networking setup is resilient to failures. They are considering a topology that allows for alternative paths in case of a node or connection loss. Which topology offers this feature?
- Ring
- Linear
- Star
- Mesh
SecureData Co. should opt a Mesh topology for their new networking setup to ensure resilience to failures through alternative paths in case of a node or connection loss. A mesh topology is characterized by each node being connected to one or more other nodes in the network, allowing for multiple pathways for data to travel. This feature is crucial for creating a network that can automatically reroute data along another path if one node or connection fails, thereby maintaining uninterrupted service. There are two types of mesh topologies: full mesh, where every node is connected to every other node, and partial mesh, where nodes are selectively interconnected. Both types offer improved redundancy and fault tolerance compared to other topologies.
