Oracle Communications Session Border Controller — Question 36

To ensure proper operation of a Session Border Controller High Availability (HA) pair, it is critical that both of the devices can originate legitimate traffic on media interfaces independent of the network interface IP address.
How is this type of traffic accommodated?

Answer options

• A. by setting the pri-utility-addr, sec-utility-addr, and sec-gateway values to addresses in the same subnet as the IP address configured on the management interfaces
• B. by setting the pri-utility-addr, sec-utility-addr, and sec-gateway values to addresses in the same subnet as the IP address configured on the media interfaces
• C. by setting the utility address and sec-gateway values to addresses in different subnets as the IP address configured on the wancom interfaces
• D. by setting a unique address on the wancoml and wancom2 interfaces via the utility address command
• E. via the utility address parameters on the wancoml and wancom2 interfaces

Correct answer: A

Explanation

The correct answer is A because it ensures that the primary and secondary utility addresses, along with the secondary gateway, are in the same subnet as the management interface's IP address, allowing for proper traffic origination. Options B and C are incorrect because they focus on the media or WAN interface subnets, which do not meet the requirement for HA operation. Options D and E do not address the necessary subnet alignment for legitimate traffic generation.
