A network link must pass through an area with significant electromagnetic interference. Which medium has the stated advantage of being immune to that interference?
- A
Use fiber-optic cable, because it carries light and is immune to electromagnetic interference.
- B
Use unshielded twisted-pair copper, because it is immune to electromagnetic interference.
- C
Use coaxial cable, because it carries light and is immune to electromagnetic interference.

Two devices on the same physical switch are assigned to different VLANs and need to communicate. What is required to enable that communication?
- A
Add a trunk port between the devices; a trunk alone routes traffic between VLANs.
- B
Use a Layer 3 device, such as a router or Layer 3 switch, to route between the VLANs.
- C
Connect both devices to the same physical switch; this removes their Layer 2 isolation.

What does 802.1Q tagging identify when frames travel on a VLAN trunk?
- A
It identifies the source MAC address a switch uses to learn its forwarding table.
- B
It specifies the wireless network name users select.
- C
It identifies the VLAN associated with frames on a trunk.
- D
It guarantees the maximum real-world speed of an Ethernet link.

Which statements accurately compare the typical characteristics of Wi-Fi frequency bands? Select all that apply.
- A
The 2.4 GHz band generally offers broader reach but has fewer non-overlapping channel choices and is more prone to interference.
- B
The 2.4 GHz band generally has the most channel capacity and the least interference.
- C
The 5 GHz and 6 GHz bands offer more channel capacity, but their usable range and building penetration can be more limited.
- D
The 5 GHz and 6 GHz bands always provide greater usable range through buildings than 2.4 GHz.

When comparing Cat 5e, Cat 6, and Cat 6A, what does the cable category describe?
- A
The maximum Ethernet speed the cable guarantees in every installation.
- B
The cable's performance category; the achievable link also depends on other channel and equipment factors.
- C
The type of VLAN tag that frames use on a trunk.
- D
The number of MAC addresses a switch can learn.

A buyer sees a Wi-Fi generation name and a separate Wi-Fi Alliance certification on a product. Which statement correctly describes the certification?
- A
The generation name guarantees a particular real-world speed.
- B
Certification means the product uses the newest available 802.11 amendment.
- C
Certification indicates that the product passed the Wi-Fi Alliance's interoperability testing.

A switch has learned the port associated with a frame's destination MAC address. How should it forward the known unicast frame?
- A
Flood the frame to every port, including the port where it arrived.
- B
Forward the frame toward the port associated with its destination MAC address.
- C
Send the frame to a router because all unicast frames require routing.
- D
Forward the frame only to the port from which its source MAC was learned.
