CompTIA Network+ is an entry-level IT certification for network professionals. This certification helps individuals to develop knowledge and skills in IT infrastructure, covering troubleshooting, configuring, and managing networks. This certification validates a professional's understanding of emerging technologies, such as cloud and virtualization. Today, every company requires an experienced and certified Network Engineer who can develop plans to strengthen their business model. If you are seeking a role as a Network Engineer, we have compiled a list of the top CompTIA Network+ interview questions for you.
Interview Questions of CompTIA Network+
1. What is network troubleshooting?
Network troubleshooting is the process or technique for identifying, diagnosing, and resolving flaws and issues in computer networks. It is a logical process that Network Engineers use to troubleshoot critical problems and improve network performance.
2. Define DHCP?
The Dynamical Host Configuration Protocol (DHCP) is a protocol that dynamically allocates IP addresses to the devices in order to communicate over the IP network.
3. How would you get to a listing of local routing tables?
We can get to a listing of local routing tables using the commands mentioned below:
- netstat -rn
- sudo route -n
- ip route list
4. What is Network Topology?
Network topology refers to the physical layout of a computer network, describing how all network devices are connected.
- Bus Topology: A communication line connects all of the devices.
- Star Topology: A central hub device connects all nodes together.
- Ring Topology: Each node is connected to two additional nodes.
- Mesh Topology: All nodes in the network are interconnected.
- Tree Topology (Hierarchical Topology): It inherits the bus topology and is similar to the star topology.
- Daisy Chain Topology: All nodes are connected in a linear way.
- Hybrid Topology: More than one topology style is used to connect nodes.
- Point-to-Point Topology: Connects two hosts (computers, servers, etc.) through a network.
5. What is ipconfig?
Ipconfig stands for Internet Protocol Configuration and is used by Microsoft Windows to view and configure the network interface.
6. What are the most important aspects of the protocol?
The protocol's three most important components are as follows:
- Syntax: It is all about the data's formatting. This refers to the order in which content is displayed.
- Semantics: Explains what each section's bits mean.
- Timing: When and how rapidly the data should be sent.
7. Explain DNS?
DNS stands for Domain Name Server. DNS is a service that converts domain names into IP addresses.
8. What are the essential network security components?
Here are six essential components of a strong network security framework:
- Network firewall
- Intrusion Prevention System (IPS)
- Advanced threat protection
- Network Access Control (NAC)
- Web filtering
- Security Information and Event Management (SIEM)
9. What are the different kinds of network policies?
Network policies outline the specific conditions under which the network must operate. Some of the most common policies that all businesses should take into account include the following:
- Acceptable use
- Disaster recovery
- Back-up
- Archiving
- Failover policies
10. What is the difference between a node and a router?
The devices on the network are referred to as nodes. These devices could be a desktop, a server, or a virtual machine.
On a network, a router works as a traffic handler. It redirects traffic to another segment if there is a higher flow of traffic in one portion of the network.
