Interview Questions & Answers
1. Configure Secondary DNS Zone Transfers
Configure Bind9 DNS secondary servers with zone transfer replication and local-only records. Learn how to set up authoritative zone replication from primary to secondary DNS servers using AXFR/IXFR zone transfers, add location-specific local records to secondary servers, and verify zone synchronization. This guide covers configuring Bind9 secondaries, monitoring zone transfer completion, testing DNS failover when primary is unavailable, and using dig to verify authoritative responses and SOA serial numbers. Essential for multi-site DNS infrastructure, ensuring DNS availability during outages, and managing split-view DNS with local customizations.
2. Customer Order Aggregation
We are given two tables. First is customers table that contains customer's name, email, and ID. Also, second table that contains ID of the order, its amount, and ID of the customer. Our main goal is to find customers who have placed more than two orders and calculate the total number of orders and the amount they spent on them. The final result must be sorted out in descending order by total spend. A join in SQL connects two tables together based on a common column. For our task, we are more interested in inner join because it returns only the rows where there is a match in both tables. Second step is grouping by ID, name, and email from customers table because this will collapse all rows belonging to the same customer into one single group. Since we already grouped the columns, we will have to use having clause that works with groups, not rows. To get this number, we have to use ID column that we grouped before and count function that will simply find the number of orders for each group.
