One solved question, so you can see how these are marked

Which IEEE standard is known as PoE+ and provides up to 30 W from the switch port?

802.3at

802.3af (PoE) delivers up to 15.4 W per port, 802.3at (PoE+) up to 30 W, and 802.3bt (4PPoE) up to 60 W or 90 W. 802.3ab is 1000BASE-T and 802.1X is port-based authentication.

Every question in the set below is marked like this. The answers stay hidden until you pick one.

All 9 PoE & Edge Port Configuration questions in this set

Answers and explanations appear when you work through the set above.

  1. Which command displays the PoE power budget and the allocated power and state of each switch port?

    • show power inline
    • show environment power detail only
    • show interfaces power
    • show poe status

  2. Which interface command disables PoE on a port that connects to a device with its own power supply?

    • power inline never
    • power inline auto
    • no power inline enable
    • poe disable

  3. A Cisco IP phone with a PC connected to its built-in switch port is plugged into a switch. Which configuration correctly handles both the phone and the PC?

    • switchport mode access, switchport access vlan 10, switchport voice vlan 150
    • switchport mode trunk with only VLAN 150 allowed
    • switchport access vlan 150 only
    • switchport voice vlan 10 and switchport access vlan 150 on a routed port

  4. A lightweight access point in a controller-based design uses CAPWAP to reach the WLC and all WLANs are tunneled to the controller. How is its switch port normally configured?

    • As an access port in the AP management VLAN
    • As a trunk carrying every WLAN VLAN
    • As a routed port with OSPF
    • As a SPAN destination

  5. A standalone (autonomous) access point advertises three SSIDs, each mapped to a different VLAN. How should the switch port be configured?

    • As an 802.1Q trunk that carries the VLANs used by the SSIDs, with a native VLAN for AP management
    • As an access port in VLAN 1
    • As a port channel with LACP passive
    • As a voice VLAN port

  6. A hypervisor host runs virtual machines in VLANs 10, 20 and 30 on a single physical uplink. Which switch port configuration fits?

    • A trunk port allowing VLANs 10, 20 and 30
    • An access port in VLAN 10
    • A routed port with no VLAN
    • A port with switchport voice vlan 20

  7. Which two settings are typical for a switch port connected to a single desktop PC?

    • switchport mode access and spanning-tree portfast
    • switchport mode trunk and spanning-tree guard root
    • channel-group mode active and switchport nonegotiate
    • power inline static and ip routing

  8. A firewall cluster uses two switch ports bundled with LACP. Which pair of channel-group modes on the switch and the appliance will form the bundle?

    • active and passive
    • passive and passive
    • on and active
    • desirable and auto

  9. An IoT camera powered by PoE keeps rebooting when other devices are plugged into the same switch. The 'show power inline' output shows the switch power budget is nearly fully used. What should the engineer conclude?

    • The switch may not have enough PoE budget for all devices, so total power or priorities need review
    • The camera's VLAN is wrong
    • STP has blocked the port
    • The port needs a voice VLAN
