A network engineer is designing a backbone link between two core switches in the same building, about 150 meters apart. The link will use 10 Gbps optics. The engineer has both single-mode and multimode fiber available. Which fiber type should be used?

Single-mode fiber, because it is always the best choice for backbone links.

Multimode fiber, but only if using SC connectors.

Multimode fiber, because it is cheaper and supports 10 Gbps at 150 meters.

Single-mode fiber, because it is required for any distance over 100 meters.

A small office is upgrading its network to support 1 Gbps Ethernet to each desktop. The existing cabling is Cat5e UTP, and the patch panels and wall jacks are all terminated with RJ-45 connectors. The office manager wants to avoid pulling new cable if possible. What should you recommend?

Upgrade the network interface cards to 10 Gbps to overcome Cat5e limitations.

Use Cat6 cable for the horizontal runs but keep Cat5e patch cords.

Replace the Cat5e cable with Cat6a to ensure 1 Gbps performance.

Keep the Cat5e cabling and verify that all terminations meet the TIA/EIA-568 standard.

A user reports that their DSL modem's WAN port is not connecting. The modem has a small rectangular port that is narrower than an RJ-45 and accepts a 6-position connector. The technician has a box of RJ-45 cables. What should the technician do?

Use a fiber optic cable with an LC connector.

Use an RJ-45 cable; it will fit the port with slight force.

Replace the modem with one that has an RJ-45 WAN port.

Obtain an RJ-11 cable for the DSL connection.
