A company is setting up a new office and wants to deploy IP phones. The phones are PoE-capable, and the administrator wants to avoid using power adapters. The switch has 24 ports, but only 12 are PoE-enabled. The office has 15 IP phones. What should the administrator do?

Connect all 15 phones to the PoE ports, even if some are not PoE-enabled

Replace the switch with one that has 24 PoE ports

Use the 12 PoE ports for 12 phones and use power adapters for the remaining 3 phones

Use PoE injectors for all 15 phones

What is the primary purpose of the console port on a Cisco router?

To supply power to connected devices such as IP phones

To attach external storage for firmware backup

To connect the router to a high-speed fiber optic uplink

To provide out-of-band management access for configuration and troubleshooting

A network engineer is upgrading a switch in a data center. The switch has SFP ports, and the current uplink uses a copper cable. The new uplink will use fiber to connect to a core switch 500 meters away. What should the engineer do to use the SFP ports for this fiber connection?

Insert a fiber SFP module into the SFP port and connect the fiber cable.

Connect the fiber cable directly to the RJ45 Ethernet port.

Use a copper SFP module and a media converter to connect the fiber.

Replace the switch with one that has built-in fiber ports.

A network technician is deploying a new switch in a remote wiring closet. The switch has no IP address configured, and the technician needs to perform the initial configuration from a laptop that has no Ethernet port. Which port on the switch should the technician use, and what is the primary purpose of that port?

Use the console port with a USB-to-serial adapter to access the CLI for out-of-band management.

Use an Ethernet port with a USB-to-Ethernet adapter to access the switch's web interface.

Use the SFP port with a copper transceiver to connect the laptop directly to the switch.

Use the USB port to load a pre-configured startup configuration from a flash drive.

A retail store is installing VoIP phones on each employee's desk. The store has a limited number of power outlets, and the phones support Power over Ethernet. The network switch is PoE-enabled. What is the best way to power the phones?

Use fiber optic ports with media converters to provide power.

Connect each phone to a PoE-enabled Ethernet port on the switch.

Use the console port to power the phones.

Use a power adapter for each phone and connect to standard Ethernet ports.
