Memcached is a distributed memory caching system used to speed up dynamic database-driven websites. A memcache server is installed in the lab environment (localhost). The objective of this challenge is to interact with the memcache server and answer the following:


  1. What is the version of memcache server?
  2. What is the value stored in key "name"?
  3. What is the length of data stored in key “password” ?
  4. How many key value pairs are present on the server initially?
  5. What command will you use to increment value of key “id” by 1
  6. What command will you use to decrement value of key “id” by 3
  7. What command will you use to add key “phone” with value “123454321” ?
  8. What command will you use to replace value of key “nick” to “ed” ?
  9. What command will you use to prepend “house ” to value of key “address” ?
  10. What command will you use to append pin code “,73301” to value of key “address” ?
  11. What command will you use to delete key “old_address”?
  12. What command will you use to invalidate all key values after 30 seconds?

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
