A company is deploying Avaya Session Border Controller for Enterprise (SBCE) to support SIP trunking. What is the minimum number of IP-addresses they need to assign to the private and public Network…

Question

Options

• ATwo addresses are assigned to the private NIC and two addresses are assigned to the public
• BOne address is assigned to the private NIC and one address is assigned to the public NIC.
• CTwo addresses are assigned to the private NIC and one address is assigned to the public NIC.
• DOne address is assigned to the private NIC and two addresses are assigned to the public NIC.

• A
  6% (3)
• B
  88% (45)
• C
  2% (1)
• D
  4% (2)

Explanation

Option B is correct because the Avaya SBCE's minimum viable configuration for SIP trunking requires only one IP address per NIC - one on the private (internal/enterprise) side and one on the public (external/carrier) side - which satisfies the basic routing and signaling requirements without redundancy.

Options A and C are wrong because they assign two addresses to the private NIC, which implies a redundant or sub-interface configuration that goes beyond the minimum requirement. Option D is wrong for the same reason but on the public side - two public addresses suggest multi-homing or redundancy, again beyond the minimum. Options A, C, and D all describe valid expanded deployments, not the minimum.

Memory tip: Think "1 in, 1 out" - at minimum, the SBCE acts as a bridge with one foot inside (private) and one foot outside (public), each needing just one IP address to pass traffic. If a choice has any "two addresses" on either NIC, it's describing more than the minimum.
