CCNA Routing and Switching (legacy) — Question 1

Which two statements about using leased lines for your WAN infrastructure are true? (Choose two.)

Answer options

• A. Leased lines provide inexpensive WAN access.
• B. Leased lines with sufficient bandwidth can avoid latency between endpoints.
• C. Leased lines require little installation and maintenance expertise.
• D. Leased lines provide highly flexible bandwidth scaling.
• E. Multiple leased lines can share a router interface.
• F. Leased lines support up to T1 link speeds.

Correct answer: C, D

Explanation

Option C is correct because leased lines typically require less specialized knowledge for installation and upkeep compared to other WAN solutions. Option D is also correct since leased lines can be adjusted for bandwidth as needed. The other options are incorrect as leased lines are generally more expensive (A), can still experience latency issues (B), may not support multiple lines on one interface in all scenarios (E), and while they can support T1 speeds, they can also support higher speeds (F).
