ITEC 1025 Module 3 Exam Questions And Answers 100% Verified. What is a switch? - answerconnects computers to a LAN and keeps track of MAC address. What is a router? - answerconnects LANs together using IP subnets. Briefly explain the concept of Hardware Redundancy and apply the concept to ensure that a network will continue to operate even if a power supply in a switch fails: - answerHardware redundancy provides fault tolerance. If a switch has a separate power supply (a redundant power supply), it will continue to operate even if the primary power supply fails. Briefly explain why a the 2nd Ethernet port an a router is typicality name E01: - answerComputers and networking equipment are based upon Binary data; the binary digits are 0 and 1. Therefore, most computer numbering begins with 0. sidebar page 157 Layer 3 switches create separate broadcast domains. - answerA Layer 3 switch works as a router and a router creates separate broadcast domains. A Layer 3 switch typically routes traffic quicker than a traditional router. - answerFalse, The fundamental difference between a router and a Layer 3 switch is that Layer 3 switches have optimized hardware to pass data as fast as Layer 2 switches, yet they make decisions on how to transmit traffic at Layer 3, just like a router. Within the LAN environment, a Layer 3 switch is usually faster than a router because it is built on switching hardware. Name two things that you can implement on a managed switch to improve security: - answerPhysical Security: Keep network Hardware protected in a locked room or or rack Password Security: Change default passwords to a complex (not default) password, never use blank passwords Secure Access: Use SSH to remotely access switches Use SNMP 3 to remotely manage switches Port Security: In smaller networks ports can be mapped to only accept traffic from specific MAC addresses Hardware Redundancy: adding redundancy such as extra power supplies that address single points of failure.
