CCNA sample questions set 23

In this article, I describe some CCNA sample questions for practice before appearing in the CCNA 200-301 exam. The following questions are basic questions and related to the CCNA sample questions set 23. There are multiple sample questions set on this website for prior practice online. All questions are described with relevant answers. You can take the following questions and answer as reference for CCNA 200-301 exam. You may also need to do more practice with other websites and books to practice the CCNA sample questions set 23. 

Question 1. What is a VLAN trunking?

VLAN trunking is a technology used to carry multiple VLANs over a single network link. It enables network administrators to extend VLANs across a network and allow multiple VLANs to communicate with each other, even when they are not physically connected. VLAN trunking works by tagging Ethernet frames with a special header that identifies the VLAN to which the frame belongs. This header is then used by switches and routers to forward the frame to the correct VLAN. VLAN trunking is commonly used in large enterprise networks to segregate traffic and improve network performance and security. This is the answer to question 1 of CCNA sample questions set 23.

Question 2. What is a STP?

STP stands for Spanning Tree Protocol, which is a protocol used in network switches to prevent loops in the network topology. When there are multiple paths between switches in a network, without STP, broadcast and multicast traffic can cause loops, leading to congestion and network failures. STP allows switches to dynamically determine the best path to send traffic, while blocking redundant paths to prevent loops. STP creates a spanning tree of the network, with the switches as nodes, and the links between them as edges. It elects a root bridge, and then determines the shortest path from each switch to the root bridge. STP is a fundamental protocol in Ethernet networks and is standardized by the IEEE 802.1D protocol. This is the answer to question 2 of CCNA sample questions set 23.

Question 3. What is a VTP?

VTP stands for VLAN Trunking Protocol, which is a Cisco proprietary protocol that allows for automatic synchronization of VLAN configurations across a network. VTP is used to manage VLAN configurations across a group of switches and is designed to reduce administrative overhead in a large network. 

With VTP, one switch in the network is designated as the VTP server, and other switches can be configured as VTP clients. The VTP server maintains the VLAN database and communicates with the VTP clients to ensure that all switches have the same VLAN configuration. When a change is made to the VLAN configuration on the VTP server, the change is propagated to all of the VTP clients in the network. This allows VLAN configurations to be easily managed and updated across the network. This is the answer to question 3 of CCNA sample questions set 23.

Question 4. What is a RSTP?

RSTP stands for Rapid Spanning Tree Protocol, which is an enhancement to the original Spanning Tree Protocol (STP). RSTP is used to prevent loops in redundant network paths and to maintain a stable network topology. It works by dynamically managing port roles and states, and by responding to network changes more quickly than STP. RSTP offers faster convergence times, increased network stability, and support for multiple spanning trees, making it a more efficient and scalable solution for modern networks. This is the answer to question 4 of CCNA sample questions set 23.

Question 5. What is a MSTP?

MSTP stands for Multiple Spanning Tree Protocol. It is an IEEE standard that allows for the creation of multiple spanning trees in a network. Unlike STP (Spanning Tree Protocol) and RSTP (Rapid Spanning Tree Protocol) which support only a single spanning tree, MSTP can support multiple spanning trees. 

In MSTP, the network is divided into multiple regions or groups, with each region having its own unique spanning tree. Within a region, the switches agree on a common set of VLAN-to-instance mappings, which allows them to share the same set of spanning trees. MSTP provides more efficient use of network resources by allowing multiple VLANs to share the same spanning tree, reducing the number of spanning tree instances needed in the network. This makes it particularly useful for large enterprise networks. This is the answer to question 5 of CCNA sample questions set 23.
