Cabling & Media Practice Questions

Updated for CCNA v2.0

Copper and fibre types, distance limits, straight-through versus crossover, and duplex mismatches.

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

What is the maximum channel length specified for 1000BASE-T over standards-compliant balanced twisted-pair cabling?

100 meters

1000BASE-T supports a 100-metre channel, including the horizontal cable and patch cords. Other copper Ethernet PHYs and cable categories can have different limits, so 100 metres is not a universal rule for every copper technology.

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

All 6 Cabling & Media questions in this set

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

  1. A campus needs a 10-Gbps, 4 km Ethernet link between two buildings. Which media type is appropriate?

    • Cat6a shielded twisted pair
    • Multimode fibre
    • Single-mode fibre
    • Coaxial cable

  2. Which pair of devices traditionally requires a crossover cable when auto-MDIX is not in use?

    • PC to switch
    • Router to switch
    • Switch to switch
    • Router to switch access port

  3. A 100-Mbps copper link has poor throughput. SW1 reports `Full-duplex, 100Mb/s` with increasing FCS errors; SW2 reports `Half-duplex, 100Mb/s` with increasing late collisions. What fault does this evidence identify?

    • A duplex mismatch between the two ends
    • The cable exceeds 100 metres
    • The VLAN is missing from the trunk
    • Spanning tree has blocked the port

  4. Which advantage does fibre optic cabling have over copper in an industrial environment with large motors nearby?

    • It is cheaper to terminate in the field
    • It is immune to electromagnetic interference
    • It supports Power over Ethernet at higher wattages
    • It can be spliced without any special tooling

  5. Which cable standard is required to run 10 Gbps over a full 100 metre copper channel?

    • Cat5
    • Cat5e
    • Cat6
    • Cat6a

  6. Which connection type is used to perform initial out-of-band configuration on a switch that has no IP address yet?

    • An SSH session to the management VLAN
    • A console connection to the console port
    • A Telnet session to the default gateway
    • An HTTPS session to the web interface
