Certified Ethical Hacker (CEH) — Question 88

You have the SOA presented below in your Zone.
Your secondary servers have not been able to contact your primary server to synchronize information. How long will the secondary servers attempt to contact the primary server before it considers that zone is dead and stops responding to queries? collegae.edu.SOA, cikkye.edu ipad.college.edu. (200302028 3600 3600 604800 3600)

Answer options

• A. One day
• B. One hour
• C. One week
• D. One month

Correct answer: C

Explanation

The correct answer is C, as the SOA specifies a Retry time of 604800 seconds, which equals one week. This means secondary servers will continue to attempt communication with the primary server for a week before they consider the zone inactive. The other options represent shorter time frames that do not align with the Retry interval defined in the SOA record.
