Networking Concepts and Issues

The video tutorial covers various network issues, including half-duplex Ethernet collisions, IPv4 broadcasts, duplicate MAC and IP addresses, multicast flooding, asymmetric routes, switching loops, and routing loops. It provides insights into troubleshooting these problems and optimizing network performance.

What is a common issue in half-duplex Ethernet networks?

• Collisions

• Bandwidth throttling

• Packet loss

• High latency

In IPv4 networks, what is a potential problem caused by excessive broadcasts?

• Increased packet size

• Higher power consumption

• Reduced network performance

• Increased security risks

What could be a reason for seeing duplicate MAC addresses on a network?

• Incorrect subnet mask

• On-path attack

• Faulty router

• Outdated firmware

What is a common method to manage multicast traffic efficiently?

• NAT traversal

• IGMP snooping

• DHCP relay

• ARP snooping

What is an asymmetric route in networking?

• A route that is only used for multicast traffic

• A route that is only used for broadcast traffic

• A route that uses different paths for inbound and outbound traffic

• A route that uses the same path for inbound and outbound traffic

What is a switching loop?

• A loop created by DHCP servers assigning IP addresses

• A loop created by firewalls blocking traffic

• A loop created by switches forwarding traffic based on MAC addresses

• A loop created by routers forwarding traffic based on IP addresses

What is a routing loop?

• A loop where DHCP servers assign IP addresses indefinitely

• A loop where switches forward traffic back and forth indefinitely

• A loop where routers forward traffic back and forth indefinitely

• A loop where firewalls block traffic indefinitely

How can you identify an asymmetric route?

• Using a traceroute

• Using a packet capture

• Using a DHCP lease

• Using a ping test

What is a potential consequence of not running spanning tree protocol?

• Duplicate IP addresses

• Multicast flooding

• Increased latency

• Switching loops

What might cause a missing route in a routing table?

• Incorrect subnet mask

• Duplicate MAC address

• No next hop configured

• Multicast flooding
