Oracle Communications Session Border Controller — Question 19

Which two statements are true about a realm on the Session Border Controller?

Answer options

• A. It can only have one steering pool port per realm.
• B. It is a layer 3 abstraction of a VoIP network.
• C. It is a logical definition of a network or group of networks comprising devices that provide real-time communication.
• D. It is a layer 5 abstraction of a VoIP network.
• E. It is a collection of IP devices that perform IP routing functions.

Correct answer: B, C

Explanation

Options B and C are correct because a realm provides a layer 3 abstraction of a VoIP network and defines a logical structure for real-time communication devices. Option A is incorrect as a realm can have multiple steering pool ports, D is wrong because a realm is not a layer 5 abstraction, and E does not accurately define a realm, which is focused on real-time communication rather than just IP routing.
