Citrix ADC 13 Advanced Topics – Security, Management and Optimization — Question 53

A Citrix Administrator configured global server load balancing (GSLB) for www.citrix.com, with two ADNS services named Citrix ADC 1 and Citrix ADC 2 in the setup.
Which record does the administrator need to add on the parent DNS server to delegate requests from www.citrix.com to Citrix ADC 1 and Citrix ADC 2?

Answer options

• A. Canonical Name (CNAME)
• B. Address (A) record
• C. Name Server (NS) record
• D. Pointer Record (PTR)

Correct answer: C

Explanation

The correct answer is C, as a Name Server (NS) record is necessary to delegate authority for a domain to another DNS server, in this case, the Citrix ADC services. The other options, such as CNAME and A records, do not perform the delegation required for GSLB setup.
