a. Are the maximum distances for UTP and optical fiber transmission shown in Figure 5-12 and Figure 5-16 distance limits for physical links or data links?

15a1.) At what layer is the 100BASE-TX standard?

a. Physical

b. Data link

c. Internet

d. Physical and data link

15a2.) UTP and fiber distance limits are for _____.

a. Physical links

b. Data links

c. Internet routes

d. Physical and data links

b. In Figure 5-21, what would the maximum data length be if the physical link on the left was OM4 fiber?

c. If you need to span 600 meters at 1 Gbps, what options do you have? (Include the possibility of using an intermediate switch.)

15c.) If you can span the distance between two switches with either a single optical fiber link or two UTP lengths with an intermediate switch, which should you choose?

a. Single optical fiber link

b. Two UTP cords with an intermediate switch

c. Both are equally attractive.

d. Neither will work.

d. How would you decide which option to choose?

e. If a distance can be spanned by UTP or optical fiber, why would you almost never add an intermediate switch?

15e.) To span the distance between two switches, why is adding an intermediate switch not an attractive choice?

a. Latency

b. Errors

c. Speed restrictions

e. Expense
