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

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: BC 
Explanation 
Explanation/Reference: 
The advantages of leased lines include: 
+ Simplicity: Point-to-point communication links require minimal expertise to install and maintain. 
+ Quality: Point-to-point communication links usually offer high service quality, if they have adequate bandwidth. The dedicated capacity removes latency or jitter between the endpoints. 
+ Availability: Constant availability is essential for some applications, such as e-commerce. Point-to-point communication links provide permanent, dedicated capacity, which is required for VoIP or Video over IP. 
The disadvantages of leased lines include: 
+ Cost: Point-to-point links are generally the most expensive type of WAN access. The cost of leased line solutions can become significant when they are used to connect many sites over increasing distances. In addition, each endpoint requires an interface on the router, which increases equipment costs. 
+ Limited flexibility: WAN traffic is often variable, and leased lines have a fixed capacity, so that the bandwidth of the line seldom matches the need exactly (therefore answer D is not correct). Any change to the leased line generally requires a site visit by ISP personnel to adjust capacity.(Reference: Connecting Networks Companion Guide Book published by Cisco Networking Academy – Page 54)
