Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 84

An engineer is designing a load balancing solution for two Cisco Unified Border Element routers. The first router (cube1.abׁ.com) takes 60% of the calls and the second router (cube2.abc.com) takes 40% of the calls. Assume all DNS A records have been created. Which two SRV records are needed for a load balanced solution? (Choose two.)

Answer options

• A. _sip._udp.abc.com 60 IN SRV 2 60 5060 cube1.abc.com
• B. _sip._udp.abc.com 60 IN SRV 60 1 5060 cube1.abc.com
• C. _sip._udp.abc.com 60 IN SRV 1 40 5060 cube2.abc.com
• D. _sip._udp.abc.com 60 IN SRV 3 60 5060 cube2.abc.com
• E. _sip._udp.abc.com 60 IN SRV 1 60 5060 cube1.abc.com

Correct answer: C, E

Explanation

The correct answers C and E provide the necessary SRV records for the load balancing configuration, with E allocating 60% of calls to cube1 and C designating 40% to cube2. Options A, B, and D do not correctly reflect the required weights for effective load balancing between the two routers.
