ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 142

Which two statements identify differences between single-homed and dual-homed WAN topologies? (Choose two.)

Answer options

• A. Dual-homed topologies provide greater redundancy than single-homed topologies
• B. Only dual-homed connections require dynamic routing to the ISP
• C. Single-homed topologies are more costly to an enterprise than dual-homed topologies
• D. Only dual-homed connections are connected to the same ISP
• E. Single-homed topologies are more appropriate for small-business networks than dual-homed topologies AE

Correct answer:

Explanation

Option A is correct because dual-homed topologies indeed provide improved redundancy by having multiple connections. Option E is also correct as single-homed topologies are often more suitable for small businesses due to lower costs and simpler management. The other options are inaccurate; B is wrong because both types can use dynamic routing, C is incorrect since single-homed can be less costly, and D is misleading as single-homed connections can also connect to the same ISP.
