CompTIA Network+ Readiness Test

10 questions, balanced across the exam's topics. Answer each one, then submit for your practice readiness estimate and per-topic breakdown. This is a practice estimate — not a prediction or guarantee of your official exam result.

Question 1

Which example most directly illustrates Site-to-site VPN?

A router filters traffic by source, destination, protocol, and port under an approved policy. A team enables authenticated and encrypted SNMP management instead of relying only on a community string. Two branch gateways establish an encrypted path for traffic between their private networks. A workstation must authenticate before a managed switch port admits ordinary network traffic.

Question 2

Which example most directly illustrates Incorrect VLAN assignment?

A wired endpoint and switch both show no link on a connected port. A tester reports pairs connected to the wrong pins at one end. A host responds to an approved reachability probe but its required application listener does not accept connections. A moved workstation reaches the guest subnet because its new switch port belongs to the guest VLAN.

Question 3

Which example most directly illustrates Baseline measurement?

A device no longer receives security fixes from its vendor, prompting a risk-based replacement plan. A discovered unmanaged switch is assigned a responsible team for lifecycle and configuration decisions. A team records typical latency and throughput before evaluating a reported slowdown. An approved monitoring appliance receives copies of traffic traversing designated switch ports.

Question 4

Match each description to its most specific topic, in the order shown. I. An administrator publishes the four-octet address of a web host in DNS. II. A device connects an office subnet to another IP network using routing information.

I: DNS A record; II: UDP I: Router; II: DNS A record I: DNS A record; II: Router I: DHCP service; II: Router

Question 5

Which statement most accurately describes Software-defined networking?

A directional antenna concentrates radio energy toward a selected area. STP controls Layer 2 forwarding paths to prevent switching loops. Software-defined WAN policy directs traffic across available wide-area transports. A separated control function centrally programs forwarding behavior.

Question 6

Which example most directly illustrates Network segmentation?

A network administrator supplies a password and a registered hardware factor before opening a management session. A router filters traffic by source, destination, protocol, and port under an approved policy. Guest users cannot initiate connections into the administrative management subnet. An access port is configured to reject unexpected MAC addresses beyond its approved policy.

Question 7

Which term or topic best matches the following description? A service feels slow even though its bulk-transfer bandwidth is high, so round-trip time is examined.

Latency measurement Bandwidth saturation Duplex mismatch Incorrect fiber polarity

Question 8

Match each description to its most specific topic, in the order shown. I. Network upgrades are scheduled when affected services have agreed downtime. II. A vendor stops selling a hardware model and the organization plans its longer-term replacement path.

I: Maintenance window; II: EOL planning I: EOL planning; II: Maintenance window I: Asset ownership; II: EOL planning I: Maintenance window; II: Port mirroring

Question 9

A conventional IPv4 subnet is 10.24.0.0/26. Excluding its network and broadcast addresses, how many host addresses are usable?

63 64 62 30

Question 10

Which example most directly illustrates Dynamic routing?

A workstation port is assigned to the staff VLAN without endpoint VLAN tagging. A link design checks both endpoint optics against the fiber type and distance before deployment. Clients in two separate VLAN subnets communicate through a configured Layer 3 interface. Routers adjust learned routes after a link-state change is propagated.
