100-150 Question 94
Select 3A company is deploying a new VoIP (Voice over IP) phone system and plans to connect all the phones to the network. During a network assessment, you notice that several desktop computers and IP cameras will also be sharing the same switches. What type of media or endpoint configuration should you prioritize to ensure efficient operation of all devices?
- A
Enable Quality of Service (QoS) on the switches to prioritize VoIP traffic.
- B
Use Power over Ethernet (PoE) to power the VoIP phones and IP cameras.
- C
Deploy separate VLANs for VoIP phones and other endpoints like computers and cameras.
- D
Configure VoIP phones to use a dedicated wireless network to avoid congestion.
- E
Upgrade all Ethernet cables to Cat 7 to support higher speeds for VoIP traffic.
Show answer and explanation
Correct answers: A, B, C
Explanation
To ensure efficient operation of VoIP phones and other endpoints, it is critical to prioritize traffic using Quality of Service (QoS), provide power using Power over Ethernet (PoE), and segregate traffic using VLANs. These measures ensure reliability and performance for latency-sensitive VoIP traffic while maintaining overall network efficiency. Wireless networks and cable upgrades are less relevant or unnecessary for most typical VoIP deployments.
- A. Correct.
Enabling Quality of Service (QoS) ensures that VoIP traffic, which is latency-sensitive, gets higher priority over less time-critical traffic like file transfers or web browsing.
- B. Correct.
Power over Ethernet (PoE) is essential to power devices like VoIP phones and IP cameras without needing additional power adapters, simplifying deployment and reducing cable clutter.
- C. Correct.
Using separate VLANs for VoIP and other traffic isolates network traffic, which reduces congestion and ensures VoIP performance is not impacted by other devices.
- D. Incorrect.
Configuring VoIP phones to use a dedicated wireless network may introduce latency and reliability issues compared to a wired network, which is more stable for time-sensitive traffic.
- E. Incorrect.
Upgrading to Cat 7 cables is unnecessary for most VoIP implementations, as VoIP phones typically require only a small fraction of the bandwidth supported by Cat 5e or Cat 6 cables.
