Getting a job as a network associate is an excellent way to start a career in IT and networking However, you’ll need to impress potential employers with your technical knowledge during the interview process. Review these common network associate interview questions and example answers to get ready for your big day.
1. What are your responsibilities as a network associate?
As a network associate your core duties involve installing, configuring and maintaining network infrastructure equipment like routers switches, firewalls, Wi-Fi access points and cabling. You’ll work closely with senior network engineers to troubleshoot network issues, upgrade equipment and implement new technologies. Customer service is also key – you’ll need strong communication skills to interface with end users and explain tech issues in plain language.
2. What are some essential skills for a network associate role?
To succeed as a network associate, you’ll need:
- Strong technical knowledge of networking protocols like TCP/IP, DNS, DHCP, VPNs, VLANs etc.
- Hands-on experience installing/configuring network devices like routers, switches and firewalls. Cisco or Juniper experience is a plus.
- Troubleshooting skills to identify and resolve network connectivity and performance issues.
- Customer service skills to communicate with non-technical end users and leadership.
- Ability to lift/mount network equipment and cabling (up to 50 lbs).
- Willingness to be on call and work non-standard hours when issues arise.
3. What are some examples of network infrastructure you have worked on?
Every day at my job as a helpdesk worker, I deal with Cisco switches and routers, SonicWall firewalls, Cat5 and Cat6 cables, wireless access points, and VPN connections. I was in charge of a project not long ago to get our core switches upgraded to the Cisco Nexus 3000. To connect the new switches to the current network, I set up trunk ports, VLANs, and port security on them. The upgrade went smoothly with no downtime.
4. How do you stay up-to-date on the latest networking trends and technologies?
I regularly read industry publications like Network World, take online courses, and attend local tech events to keep my skills current. I’m particularly interested in learning more about SD-WAN, network automation and Cisco’s DNA Center management platform. I also have my CCNA certification which required hands-on training in key Cisco technologies.
5. How would you go about troubleshooting a slow network connection issue?
First, I would talk to the end user to find out exactly when and where the problem happens. I would use network monitoring tools like SolarWinds to check network devices like switches and routers for errors, lost connections, or that they are being used too much. To find the source of the problem, I would check the network’s bandwidth speeds at different locations. If it’s a specific device, like a broken switch port, I would get a new one. For capacity issues, I’d recommend upgrading bandwidth.
6. You find a user’s computer infected with malware. What steps should you take?
First, I would isolate the infected computer from the network immediately to prevent it from spreading malware. Next, I would use antivirus software to scan and remove any infections. Once cleaned, I would change the user’s network credentials to new strong passwords in case the malware compromised their existing ones. Finally, I would implement network security measures like updated firewall rules, stronger wireless encryption, and user education to help prevent future infections.
7. How would you go about setting up a new branch office network?
I would start by surveying the office layout, number of users and equipment needs to develop a networking plan. I would install new routers, switches, firewalls, Wi-Fi access points and cabling. I would configure the routers to enable site-to-site VPN connectivity back to headquarters. On the switches, I would setup VLANs to segregate traffic and enable spanning tree protocol to prevent loops. I would implement access control lists on the firewall to secure the network. Once equipment is in place, I would thoroughly test network functionality for users in the new office.
8. What are important steps when installing a new network switch?
When installing a new switch, it’s critical to properly configure the device before connecting it to the network. I would assign it a unique hostname and IP address. I would implement port security to prevent unauthorized access. I would enable spanning tree protocol to prevent switching loops. I would setup VLANs to logically segment traffic. I would configure trunk ports to interconnect switches. Once the initial config is complete, I would connect the switch to the network and test it thoroughly before allowing users on it.
9. How would you troubleshoot an issue where users can’t access the internet?
I would first verify that users can reach internal network resources like servers and printers. If internal resources are accessible, it points to an external connectivity problem. I would check the physical connections to routers and modem. I would verify that network devices have the proper external interface configurations and IP addresses. I would ping external websites by IP address and hostname to see if DNS resolution is working. I would also check if the ISP is experiencing an outage. If the issue persists, I would engage the ISP support team to troubleshoot further.
10. An end user is experiencing intermittent network connectivity problems. What are some troubleshooting steps?
Intermittent connection issues can be tricky to pin down. I would start by having the user document exactly when the problem occurs to identify any patterns. I would check cabling connections to eliminate loose wires. I would review switch port configurations for errors. I would monitor the port statistics on the user’s switch port to check for excessive errors or drops. If the issue persists, I would move the user’s computer to a different network jack to see if the problem follows. If it’s tied to a physical port, it could indicate a bad port, cable or nic. Isolating the issue in this way allows you to replace specific components.
Getting comfortable answering technical questions about networking protocols, equipment and troubleshooting methodology will help you stand out in your network associate interviews. Highlight your hands-on experience and customer service skills. With the right preparation, you’ll be ready to impress hiring managers and land the perfect entry-level networking job.
9 What is mesh topology?
Mesh topology is a setup wherein each device is connected directly to every other device on the network. Consequently, it requires that each device has at least two network connections.
12 What is the Application of Hamming code?
Here are some common applications of using Hemming code:
- Satellites
- Computer Memory
- Modems
- PlasmaCAM
- Open connectors
- Shielding wire
- Embedded Processor
