Support Engineer Interview Questions
Support engineers help customers with their tech support concerns and challenges. They often provide support for the products and services of technology companies. These professionals also create training manuals, guides, and other support materials. You should expect a variety of technical questions and questions that test your ability to interact with customers.
Top Support Engineer Interview Questions & How to Answer
Question 1
Question #1: Name some of the latest processors and other popular upgrades for computers.
How to answer
How to answer: This question lets you showcase your knowledge about computer hardware. Talk about the latest computer processors, hard drives, and graphics cards and which applications they're best for. While a graphic designer may need a powerful processor, someone who spends most of their time typing can use an older PC with no problem.
Question 2
Question #2: Talk about a time when you solved a problem with a difficult customer.
How to answer
How to answer: People are often angry and frustrated because of issues with their hardware or software when they speak to support engineers. Use your answer to this question to show that you can stay calm and de-escalate situations with irate customers. Discuss a time when you were able to make someone satisfied, even though they were angry at first.
Question 3
Question #3: What is overclocking?
How to answer
How to answer: Overclocking is setting a computer's processor to run faster than recommended. Talk about how it can increase performance, especially for gamers, but it increases the risk of overheating. Overclocking often voids the manufacturer's warranty as well.

They don't ask "describe the seven layers of the OSI model" anymore. They should, though.

What's DHCP?
Basic technical questions
Phone Interview: 1. What is a beacon frame? It is a management frame sent out by an AP that is used to keep the devices on a wireless network associated with it, in sync. This is essential for CSMA/CA 2. What is the difference between 2.4 GHz and 5 Ghz frequencies on a wireless network? Higher Frequencies have more attenuation through Free space. 2.4 GHz can travel further. 5 GHz is a less crowded frequency band. Therefore less prone to interference 3. What are the non-overlapping channels in the 2.4 GHz frequency band? Channels 1, 6 and 11 4. How do packets travel across a network? ( Explain using an ICMP example, use all the protocols. that are involved. DHCP, ARP etc. Keep in mind the OSI model) 5. What is the difference between STP and RSTP? Technical Interview: 1. If you were to take an RF Wireless survey, would you do it when there were people in the room or when the room was empty? Always when people are in the room, humans are 60-70% water and that means more attenuation. This will be an efficient survey, only if people are in the room. 2. What happens when you type www.google.com into your computer? 3. What does the 's' in https signify? SSL communication between host and server 4.(Scenario Based) A host is trying to connect to a computer across a VPN tunnel but unfortunately it cannot access the resource. What could be the problem,assuming that the VPN tunnel is setup correctly? The correct answer is the hosts file on the computer has an incorrect mapping of the name to ip. You will know this when you ping the name of host and it resolves to a different ip. 5. (Scenario Based) A firewall in a corporate environment was one day replaced with a Meraki firewall. Now clients are no longer able to access the web server, The configuration on the different firewalls are identical. What could be the problem? The ARP cache on the modem still points to an old mapping of the Firewall. The MAC address had now changed, Therefore in order to rectify the problem, power off and power on the modem. 6. What is gratuitous ARP? 7. What are the different modes with IPSec? What is IKE Phase 1 and IKE Phase 2? main mode and quick mode 8. (Scenario-Based ), three switches are connected together in a triangle design, A, B and C, Who becomes the Root bridge? What is the default priority on Cisco switches? Can a switch have a priority of 0? When the speed of the links are changed, does the root port also change? 9. What is the difference between PVST and PVST+? 10. Name one channel in a 5 GHz band? 11. Explain to me how DNS works? Cultural interview: 1. (Scenario-based) There is a set of core and distribution switches, there are three VLANs spanned across all switches, RSTP is functioning correctly, a user connected to VLAN 2 cannot access the internet, what could be the problem? Ans: you must deduce that if everything is configured correctly and there are no physical issues with the network, the correct answer is that there is a rogue DHCP server in VLAN 2. You need to shutdown the port connected to the rogue DHCP server. First, find out the MAC address of the rogue DHCP server from the arp cache of the host computer. arp -a. Secondly, from the CAM address table of the switch, see which port is associated with the MAC address. Thirdly, block the port.Fourthly, ipconfig /release and ipconfig /renew on the host computer to get a legitimate IP address from the real DHCP server in VLAN 2. Alternative solution would be to enable DHCP Snooping. 2. if the logs on a linux apache server are suddenly not being written to ? what could be the problem? a. permissions issue b. disk space requirements c. is apache service running? d. has the location of the log file been changed on the apache configuration file? e. Check the logrotate feature.
