IBM Security Access Manager V9.0 Deployment — Question 45

A customer has three LDAP servers: A master (ds1.example.com), another master (ds2.example com) and a read-only replica (ds3.example.com) used for the
IBM Security Access Manager (ISAM) V9.0. The deployment professional has configured the ISAM runtime using ds1.example.com as the registration server.
Which configuration will provide load balancing for LDAP read across all three servers and failover to ds2.example.com for LDAP write?

Answer options

• A. replica= ds2.example.com, 389, readonly,5 replica= ds3.example.com, 389, readonly,5 replica= ds2.example.com, 389, readwrite,6
• B. replica= ds1.example.com, 389, readonly,6 replica= ds2.example.com, 389, readonly,6 replica= ds3.example.com, 389, readonly,6 replica= ds2.example.com, 389, readwrite,4
• C. replica= ds1.example.com, 389, readonly,4 replica= ds2.example.com, 389, readonly,4 replica= ds3.example.com, 389, readonly,4 replica= ds2.example.com, 389, readwrite,6
• D. replica= ds1.example.com, 389, readonly,1 replica= ds2.example.com, 389, readonly,2 replica= ds3.example.com, 389, readonly,3 replica= ds2.example.com, 389, readwrite,4

Correct answer: D

Explanation

Option D is correct as it provides the necessary load balancing for LDAP reads across all three servers while ensuring that writes are directed to ds2.example.com. The other options either do not balance the reads correctly or improperly assign write capabilities, failing to meet the specified requirements.
