1. Scenario: A company is experiencing slow loading times on their website. How would you go about troubleshooting this issue?
Candidate Answer: First, I would check the website's code and ensure that there are no unnecessary, large files that may be causing the slow loading times. I would also check the server's performance and see if there are any issues with bandwidth or server load. Additionally, I would check the website's caching settings and see if they can be optimized to improve loading times.
2. Scenario: A client needs to migrate their data from one server to another. How would you plan this migration and ensure that no data is lost?
Candidate Answer: I would first make sure to take a full backup of the data to ensure that nothing is lost during the migration process. I would then plan out the migration to take place during off-peak hours when the least amount of users are accessing the server. I would also ensure that all necessary software and systems are in place on the new server before migrating the data to minimize downtime.
3. Scenario: A company's email server is down and employees are unable to send or receive emails. How would you go about resolving this issue?
Candidate Answer: I would first check to see if there are any server issues or hardware failures causing the outage. If the issue is related to software or configuration, I would troubleshoot the issue and restore the email service. If necessary, I would inform the clients and employees of the outage and provide an estimated time for resolution.
4. Scenario: A client's website is being attacked by a DDoS attack. How would you mitigate the attack and prevent it from happening again in the future?
Candidate Answer: I would first determine the source and nature of the attack and take measures to block any malicious traffic. I would also work with the client to ensure that their website's hosting provider has adequate protection against DDoS attacks in the future, such as using a content delivery network or implementing load balancing.
5. Scenario: A client needs a new software system developed for their business. How would you gather their requirements and ensure that the software meets their needs?
Candidate Answer: First, I would meet with the client and discuss their business processes and their goals for the new software system. I would then gather their requirements and document them to ensure that they are clear and concise. I would also create a prototype of the software to ensure that it meets their needs before beginning full development. Throughout the development process, I would regularly check in with the client and provide updates to ensure that the software is meeting their expectations.
