When selecting devices for a small network, which combination of factors is most critical in ensuring the network meets all requirements while staying within budget?

• Cost, speed/types of ports, expandability, and OS features/services
• Cost, brand name, uniform ports, and basic routing functions
• Brand reputation, high-speed ports, non-expandable, and basic firewall/NAT
• Color/design, uniform ports, fixed configuration, and aesthetics over function

Which definition best describes network redundancy?

• Using multiple layers of firewalls for security
• Adding extra pathways and devices to ensure the network stays available during failures
