Section 1.6 Demonstrate your acquired knowledge about Network Topologies, Architectures and Types This will demonstrate your proficiency for section 1.6 of the Network+ 10-009 objectives. 1 / 25 Which of the following would be the most suitable architecture for a data center that handles large amounts of east-west traffic? Three-tier hierarchical model Point-to-point topology Spine-and-leaf architecture Collapsed core architecture 2 / 25 Which of the following is true about the hybrid network topology? It is a simple topology where devices are connected in a circular manner. It is composed of several different topologies integrated to meet the specific needs of the organization. It has no central hub or router. It is less scalable than a pure star or mesh topology. 3 / 25 What is the primary function of the distribution layer in the three-tier model? Providing redundancy for access switches. Filtering and routing traffic between VLANs. Connecting all devices within the network. Aggregating traffic and forwarding it to the access layer. 4 / 25 What feature distinguishes the collapsed core architecture from the standard three-tier model? It eliminates the need for an access layer. It combines the core and distribution layers into a single layer. It uses a star/hub-and-spoke design for scalability. It routes traffic only between end-user devices. 5 / 25 Which of the following is a major disadvantage of the mesh topology? Single point of failure High cost and complexity due to the large number of connections Limited fault tolerance Slow network performance due to congestion 6 / 25 What is a primary benefit of the point-to-point topology? It reduces cable management complexities. It supports unlimited scalability. It provides a direct and dedicated connection between two devices. It simplifies the management of large networks. 7 / 25 What type of traffic flow is primarily seen when data moves between two end-user devices within the same network segment? North-south traffic flow East-west traffic flow Broadcast traffic flow Multicast traffic flow 8 / 25 Which of the following network architectures is most commonly used in large-scale data centers for better network performance and scalability? Mesh topology Hybrid topology Spine-and-leaf architecture Star/hub and spoke topology 9 / 25 What is the primary purpose of the access layer in the three-tier hierarchical model? To route traffic between different networks. To provide high-speed switching and traffic aggregation. To connect end-user devices to the network and manage data flows. To aggregate data from multiple distribution layers. 10 / 25 In a spine-and-leaf network architecture, which devices are typically responsible for the routing and forwarding of traffic? Leaf switches Spine switches Core routers End devices 11 / 25 In a three-tier hierarchical model, which layer is responsible for routing between VLANs and implementing access control policies? Core Distribution Access Aggregation 12 / 25 Which of the following network topologies can handle both high redundancy and scalability by combining different topology types? Hybrid topology Mesh topology Star/hub and spoke topology Point-to-point topology 13 / 25 East-west traffic flow refers to: Traffic flowing between end-user devices and the internet. Communication between devices within the same network segment or data center. Routing data between different network subnets. Communication between a data center and a branch office. 14 / 25 Which traffic flow involves data moving from end-user devices to a centralized data center or the internet? East-west traffic flow North-south traffic flow Inbound traffic flow Outbound traffic flow 15 / 25 Which of the following is a key characteristic of the collapsed core architecture? It combines the core and distribution layers into a single layer to simplify the design. It uses multiple physical devices to provide redundant connections. It supports large-scale traffic segmentation. It is primarily used in distributed enterprise networks. 16 / 25 In the three-tier hierarchical model, the distribution layer performs which of the following? Connects end-user devices and local switches. Aggregates traffic from access switches and forwards it to the core layer. Routes traffic between different core layers. Monitors traffic and provides remote access. 17 / 25 What is the primary function of the core layer in the three-tier hierarchical model? To connect users and devices within the same subnet. To provide direct access to all devices in the network. To route traffic between different distribution layers. To aggregate data and provide high-speed, fault-tolerant communication between network segments. 18 / 25 In the three-tier hierarchical model, which layer is primarily responsible for connecting end-user devices to the network? Core Distribution Access Aggregation 19 / 25 A point-to-point network is characterized by which of the following? A network where all devices are connected to a central hub. A connection between two network devices without an intermediary. A topology where each device is connected to multiple other devices. A network in which traffic flows only in one direction. 20 / 25 What is the primary purpose of a spine-and-leaf architecture? To interconnect devices through a central hub. To use multiple spine switches to connect leaf switches for efficient, scalable network design. To allow each device to directly communicate with others. To create a single point of failure for fault isolation. 21 / 25 Which network topology best suits scenarios where each device must be able to directly communicate with every other device? Mesh Star/hub and spoke Point-to-point Hybrid 22 / 25 What is a primary advantage of using a star/hub-and-spoke topology? It requires minimal central management. It reduces the number of direct connections between devices. Devices are connected in a closed-loop configuration. It allows for equal communication between all devices without a central hub. 23 / 25 Which of the following is a disadvantage of a mesh topology? Limited scalability High redundancy and fault tolerance Complex configuration and maintenance Simple cable management 24 / 25 In a hybrid topology, how are different topologies combined? Devices are connected through a single point of failure. Multiple topologies are used together to meet the needs of the network. The network only uses point-to-point links. Only a mesh topology is used. 25 / 25 Which of the following best describes the primary characteristic of a mesh network topology? A central device manages communication between all other devices. Each device is connected to every other device. Devices are connected in a loop, allowing for continuous communication. All devices are connected to a single access point.
