CCNP - Cisco Certified Network Professional Practice Questions

Master the Wireless Networking Domain

Test your knowledge in the Wireless Networking domain with these 10 practice questions. Each question is designed to help you prepare for the CCNP - Cisco Certified Network Professional certification exam with detailed explanations to reinforce your learning.

Question 1

A network engineer needs to implement a secure guest Wi-Fi network that isolates guest traffic from the corporate network. Which feature should be configured?

A) VLAN tagging

B) Rogue AP detection

C) MAC address filtering

D) Wireless client isolation

Show Answer & Explanation

Correct Answer: D

Explanation: CORRECT: Wireless client isolation prevents guests from accessing each other's devices and the corporate network, enhancing security. VLAN tagging is part of segmentation but does not isolate clients by itself. Rogue AP detection is for security monitoring, not client isolation. MAC address filtering controls access but does not isolate traffic.

Question 2

You are designing a wireless network for a large enterprise campus that requires seamless connectivity for VoIP applications. Which wireless architecture would best support roaming without major packet loss or delay?

A) Centralized architecture with a single WLC

B) Distributed architecture with local switching

C) Hybrid architecture with SDN controllers

D) Mesh network architecture

Show Answer & Explanation

Correct Answer: A

Explanation: A centralized architecture with a single WLC allows for smooth handoff and roaming by managing all APs centrally, minimizing packet loss.

Question 3

Your enterprise network has recently upgraded to include Cisco Wireless LAN Controllers (WLCs) and multiple APs across two campuses. What configuration option would best ensure seamless roaming for clients between the campuses?

A) Configure Mobility Groups across the WLCs.

B) Use different SSIDs for each campus.

C) Implement separate VLANs for each AP.

D) Set the same RF channel for all APs.

Show Answer & Explanation

Correct Answer: A

Explanation: Mobility Groups allow clients to roam seamlessly between different WLCs without dropping the connection.

Question 4

A company is deploying a new wireless network and wants to ensure that only authorized devices can connect. They plan to use MAC filtering, but the network engineer suggests an alternative approach. What is a more secure method to control device access?

A) WPA2 with a shared password

B) 802.1X with RADIUS authentication

C) Hidden SSID

D) Static IP addressing

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: 802.1X with RADIUS authentication provides a secure method by authenticating users and devices individually. WPA2 with a shared password is less secure as it can be shared. 802.1X with RADIUS offers stronger security by requiring individual credentials. Hidden SSID does not provide real security as SSIDs can be discovered. Static IP addressing does not control access to the network.

Question 5

Which wireless security protocol provides the strongest protection by using AES encryption?

A) WEP

B) WPA

C) WPA2

D) TKIP

Show Answer & Explanation

Correct Answer: C

Explanation: CORRECT: WPA2 provides the strongest protection by using AES encryption, which is more secure than other protocols. WEP is outdated and easily cracked. WPA uses TKIP, which is less secure than AES. This is the correct answer as WPA2 uses AES. TKIP is less secure than AES and is used with WPA.

Question 6

Which wireless technology allows devices to communicate directly without an access point?

A) Infrastructure mode

B) Ad hoc mode

C) Mesh networking

D) Repeater mode

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: Ad hoc mode allows wireless devices to communicate directly with each other without the need for an access point. Infrastructure mode requires an access point for communication. This is the correct answer as ad hoc mode does not use an access point. Mesh networking involves multiple nodes and can include access points. Repeater mode extends coverage but still requires an access point.

Question 7

An enterprise network is experiencing intermittent connectivity issues with wireless clients. The network uses a centralized wireless controller architecture. Which step would best help in identifying the root cause?

A) Check the DHCP server for IP address conflicts.

B) Analyze the RF spectrum for interference sources.

C) Review the wireless controller's logs for disassociation events.

D) Increase the transmit power of the access points.

Show Answer & Explanation

Correct Answer: C

Explanation: CORRECT: Reviewing the wireless controller's logs for disassociation events can provide insights into why clients are being disconnected, such as authentication failures or interference. Checking the DHCP server is useful for IP issues but not directly for disconnections. RF spectrum analysis helps identify interference but may not directly show disassociation reasons. Increasing transmit power might exacerbate interference issues and is not diagnostic.

Question 8

A wireless network is experiencing intermittent connectivity issues in a high-density environment. The engineer suspects interference from non-Wi-Fi devices. Which tool or feature should be used to identify the source of interference?

A) Wireshark

B) Spectrum Analyzer

C) NetFlow

D) Syslog

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: A Spectrum Analyzer can detect non-Wi-Fi interference sources by analyzing the RF spectrum. Wireshark captures packet data but cannot analyze RF interference. Spectrum Analyzer is the appropriate tool for identifying RF interference. NetFlow is used for traffic analysis, not RF interference detection. Syslog provides logging information but cannot identify RF interference.

Question 9

In a wireless network, clients are experiencing poor voice quality during VoIP calls. Which QoS setting on the wireless controller should be verified?

A) WMM (Wi-Fi Multimedia) support

B) VLAN tagging

C) Access point power levels

D) SSID broadcast settings

Show Answer & Explanation

Correct Answer: A

Explanation: CORRECT: WMM support is critical for prioritizing voice traffic and ensuring good VoIP call quality. VLAN tagging helps with network segmentation but not directly with QoS for voice. AP power levels affect coverage but not QoS directly. SSID broadcast settings relate to network visibility, not QoS.

Question 10

Which security protocol is recommended for providing the most secure wireless communication in an enterprise environment?

A) WEP

B) WPA2-PSK

C) WPA3-Enterprise

D) WPA2-TKIP

Show Answer & Explanation

Correct Answer: C

Explanation: WPA3-Enterprise offers enhanced security features and is recommended for enterprise environments requiring robust security.
