Understanding Network Topologies and Standards

Which network topology is characterized by each node being connected to every other node in the network, providing high redundancy and reliability?

• Star

• Mesh

• Bus

• Ring

Analyze the advantages and disadvantages of using a star topology in a large office network. Provide a strategic plan for its implementation considering cost and scalability.

• High cost, easy to troubleshoot, scalable with additional switches

• Low cost, difficult to troubleshoot, limited scalability

• Moderate cost, easy to troubleshoot, limited scalability

• High cost, difficult to troubleshoot, scalable with additional routers

Which wireless standard operates in the 5 GHz frequency band and offers a maximum data rate of up to 54 Mbps?

• 802.11a

• 802.11b

• 802.11g

• 802.11n

Evaluate the impact of network topology choice on the performance and reliability of a wireless network in a university campus. Consider factors such as interference, coverage, and ease of maintenance.

• Star topology minimizes interference but limits coverage

• Mesh topology enhances coverage and reliability but increases complexity

• Bus topology offers high reliability but is difficult to maintain

• Ring topology provides easy maintenance but suffers from high interference

What is the primary advantage of using a ring topology in a network?

• Easy to add new nodes

• High redundancy

• Simple data packet routing

• Low cost

Design a network plan for a small business using a combination of wireless standards to optimize both speed and coverage. Justify your choice of standards.

• Use 802.11b for coverage and 802.11g for speed

• Use 802.11n for both speed and coverage

• Use 802.11a for speed and 802.11ac for coverage

• Use 802.11g for coverage and 802.11n for speed

Which network topology is most susceptible to a single point of failure?

• Mesh

• Star

• Bus

• Hybrid

Critically assess the use of 802.11ac in a densely populated urban area. Consider factors such as interference, speed, and device compatibility.

• High speed, low interference, limited device compatibility

• Moderate speed, high interference, wide device compatibility

• High speed, high interference, wide device compatibility

• Moderate speed, low interference, limited device compatibility

What is the main disadvantage of a bus topology?

• High cost

• Difficult to troubleshoot

• Limited cable length and number of nodes

• Complex installation

Propose a strategic plan for upgrading an existing wireless network from 802.11g to 802.11ac. Consider budget constraints and device compatibility.

• Gradual upgrade with dual-band routers to maintain compatibility

• Immediate upgrade with single-band routers for cost efficiency

• Gradual upgrade with single-band routers to reduce interference

• Immediate upgrade with dual-band routers for maximum speed
