CompTIA Network+ Practice Questions
Master the Network Implementations Domain
Test your knowledge in the Network Implementations domain with these 10 practice questions. Each question is designed to help you prepare for the CompTIA Network+ certification exam with detailed explanations to reinforce your learning.
Question 1
You are configuring a DHCP server for a network. The network uses a subnet mask of 255.255.255.224. How many usable IP addresses are available for hosts in each subnet?
Show Answer & Explanation
Correct Answer: C
Explanation: A subnet mask of 255.255.255.224 provides 32 total IP addresses per subnet, but 2 addresses are reserved (network and broadcast), leaving 30 usable addresses for hosts.
Question 2
A company wants to implement a wireless network with the best balance of range and speed. Which wireless standard should they use?
Show Answer & Explanation
Correct Answer: C
Explanation: 802.11n offers a good balance of range and speed, as it can operate on both 2.4 GHz and 5 GHz bands, providing better coverage and higher speeds than 802.11b and 802.11g.
Question 3
You need to configure a network to support IPv6 multicast traffic. Which of the following addresses is used for IPv6 multicast?
Show Answer & Explanation
Correct Answer: B
Explanation: The ff00::/8 address range is reserved for IPv6 multicast traffic, allowing the delivery of packets to multiple destinations simultaneously.
Question 4
An administrator needs to configure a wireless network to support multiple SSIDs on a single access point. Which feature should be utilized?
Show Answer & Explanation
Correct Answer: C
Explanation: VLAN tagging allows multiple SSIDs to be broadcast from a single access point by associating each SSID with a different VLAN, enabling network segmentation.
Question 5
An organization is expanding its network and needs to implement a routing protocol that supports VLSM and is suitable for a large network. Which of the following protocols should be used?
Show Answer & Explanation
Correct Answer: C
Explanation: OSPF (Open Shortest Path First) supports VLSM (Variable Length Subnet Masking) and is designed for large and complex networks. RIP v2 also supports VLSM, but OSPF is more scalable for large networks.
Question 6
A network administrator needs to configure a DHCP server to provide IP addresses to clients in a specific VLAN. Which of the following options must be configured on the switch connected to the DHCP server?
Show Answer & Explanation
Correct Answer: A
Explanation: DHCP relay (also known as IP helper-address) must be configured on the switch to forward DHCP requests from clients in a VLAN to the DHCP server, especially if the server is on a different subnet.
Question 7
During a network implementation, you need to ensure redundancy and load balancing at Layer 3. Which protocol would you use?
Show Answer & Explanation
Correct Answer: C
Explanation: GLBP (Gateway Load Balancing Protocol) provides both redundancy and load balancing at Layer 3, unlike HSRP and VRRP, which only provide redundancy.
Question 8
A network engineer needs to configure a switch to support VLANs. Which command should be used to assign a port to VLAN 10 in a Cisco switch?
Show Answer & Explanation
Correct Answer: B
Explanation: The command 'switchport access vlan 10' assigns a specific port to VLAN 10 on a Cisco switch. This is part of configuring access ports for VLANs.
Question 9
You are tasked with implementing a VLAN configuration on a switch. The switch has interfaces configured as follows: - Interface 1/0/1: VLAN 10 - Interface 1/0/2: VLAN 20 - Interface 1/0/3: VLAN 30 A host connected to interface 1/0/1 cannot communicate with a host on interface 1/0/2. What is the most likely reason for this issue?
Show Answer & Explanation
Correct Answer: B
Explanation: Hosts on different VLANs cannot communicate directly with each other without a router or a Layer 3 switch to route traffic between the VLANs. VLANs segment network traffic to improve security and efficiency.
Question 10
An organization needs to implement a wireless network that supports high data rates and operates in the 5 GHz band. Which IEEE standard should they choose?
Show Answer & Explanation
Correct Answer: D
Explanation: IEEE 802.11ac operates in the 5 GHz band and supports high data rates, making it suitable for environments requiring fast wireless connections.
