CompTIA Network+ Practice Test for Subdomain 2.2 #03

Welcome to today’s CompTIA Network+ practice test!

This practice test uses our new UI!

Today’s practice test is based on Subdomain 2.2 (Given a scenario, configure switching technologies and features) from the CompTIA Network+ N10-009 objectives.

This beginner-level practice test is inspired by the CompTIA Network+ (N10-009) exam and is designed to help you reinforce key networking concepts on a daily basis.

These questions are not official exam questions, nor are they brain dumps, but they reflect topics and scenarios relevant to the Network+ certification. Use them to test your knowledge, identify areas for improvement, and build daily cybersecurity habits.

CompTIA Network+ Practice Test of the Day 260612

10 questions • Single best answer

Question 1

A network administrator at a campus environment receives a requirement to logically separate traffic for three departments — HR, Finance, and IT — without recabling. All three departments share the same physical switches. What switch technology should be configured to achieve this logical segmentation?

A. Spanning tree protocol B. LACP link bonding C. VLANs D. 802.1Q QoS marking

Question 2

A network engineer is configuring a switch port that must carry tagged traffic for multiple VLANs between two switches. The port must use IEEE 802.1Q encapsulation to identify VLAN membership within each frame. What type of port is this?

A. Hybrid port B. Trunk port C. Routed port D. Access port

Question 3

A network engineer needs to ensure that a specific distribution switch becomes the central point of convergence for all STP instances in the network. This switch must win the root bridge election and all other switches should defer to it. What must be configured?

A. Lower the port cost on all uplinks of the target switch B. Enable BPDUGuard on all uplinks C. Configure the lowest STP bridge priority on the target switch D. Enable PortFast on all ports of the target switch

Question 4

A network administrator wants to restrict each access switch port to a maximum of one MAC address. If a second MAC address is detected on the port, the port should automatically shut down and generate a log message. Which feature should be configured?

A. VLAN access control list B. 802.1X port authentication C. BPDU guard D. Port security

Question 5

A network technician is deploying a multi-switch campus network and needs VLAN membership information to be preserved as frames travel between switches. Which IEEE standard defines the method for tagging frames with VLAN identifiers on trunk links?

A. 802.1X B. 802.11 C. 802.1Q D. 802.3ad

Question 6

A network engineer is replacing the legacy Spanning Tree Protocol with a faster version that achieves network convergence in under one second rather than the traditional 30–50 seconds. Which protocol should be deployed?

A. PVST+ B. LACP C. MSTP D. RSTP

Question 7

A network engineer wants to combine four 1 Gbps physical links between two switches into a single logical 4 Gbps channel using an IEEE standards-based protocol for negotiation. Which protocol and feature should be configured?

A. LACP (802.3ad link aggregation) B. PortFast on uplink ports C. RSTP for redundant paths D. VLAN trunking with 802.1Q

Question 8

Workstations in VLAN 10 need to communicate with application servers in VLAN 20. The access switches do not have Layer 3 routing capability. What must be present in the network to enable communication between the two VLANs?

A. LACP bonding between the VLAN interfaces B. A Layer 3 device such as a router or multilayer switch C. An additional trunk port between the VLANs D. An STP configuration change to unblock the VLAN paths

Question 9

A network administrator enables a switch feature on all ports connected to end-user workstations. The feature allows these ports to bypass the normal STP listening and learning states and go directly to forwarding. This feature should never be enabled on ports facing other switches. What feature is this?

A. Loop guard B. BPDU filter C. Root guard D. PortFast

Question 10

A technician is configuring a new switch and is asked to explain the difference between two port types. He describes a port type that carries traffic for only a single VLAN, does not insert 802.1Q tags, and is used for connecting end devices such as workstations and printers. What is this port type called?

A. Access port B. Routed port C. Native VLAN port D. Trunk port
