Citrix ADC 13 Advanced Topics – Security, Management and Optimization — Question 35

A Citrix Administrator needs to configure a rate-limiting policy setting DNS requests to a threshold of 1,000 per second.
Which command does the administrator need to run to correctly configure this policy?

Answer options

• A. HTTP.REQ.LIMIT()
• B. SYS.CHECK.LIMIT()
• C. SYS.CHECK.LIMIT() || CONNECTION.IP.LIMIT()
• D. SYS.CHECK.LIMIT() || HTTP.REQ.LIMIT()

Correct answer: B

Explanation

The correct command is SYS.CHECK.LIMIT() as it is specifically designed to limit the rate of DNS requests. The other options either apply to HTTP requests or are combinations that do not specifically target DNS rate-limiting, making them unsuitable for this particular requirement.
