Question 2

You have copied a new Net-Net 4000 Operating System to the Net-Net 4000 Session Border Controller and changed the boot parameters according to the display below.

On reboot, the Net-Net 4000 is in a boot loop. Which two scenarios could cause the boot loop?

A. Someone else was in configuration mode at the same time as you. B. You mistyped the name of the Net-Net 4000 OS file in the file name property of the boot parameters. C. The Net-Net 4000 was reset using the reboot force command without saving and activating the configuration changes first. D. The Net-Net 4000 OS file was truncated while being copied to the /boot directory due to lack of file space. E. You did not copy the Net-Net 4000 OS file into the /code directory.

Question 3

What are two differences between the SIP NAT Bridge (SNB) and the Single SIP NAT Homed in a Trusted Network (SSNHTN) models on the Session Border Controller?

A. In the SSNHTN model, the home proxy address(HPA) is set to point to sipd. B. In the SSNHTN model, the home proxy address (HPA)is set to 1.1.1.1, as the HPA is only needed in SNB architectures. C. In the SSNHTN model, the home address and home proxy address (HPA) are addressed from a range that is in the backbone realm. D. In a SIP-NAT Bridge (SNB), multiple access and backbone realms are allowed. In the SSNHTN model, only one backbone realm is allowed. E. Where is no distinguishable difference between the two models.

Question 5

You must decide whether to deploy the policy based realm bridging with header manipulation rules (PBRB-HMR) model in your SIP peering environment.
What are two deciding factors that tip your decision for or against HMR in contrast to a SIPNAT Bridge (SNB) architecture?

A. SNB is the simplest model to troubleshoot. B. PBRB-HMR is recommended for both peering and access architectures. C. PBRB-HMR provides better topology hiding, at the expense of performance. D. PBRB-HMR has lower performance overhead than SIP-NAT Bridge. E. PBRB-HMR is much easier to configure, even though it has similar performance to the SNB model.

Configure the al low-anonymous parameter under the sip-port to realm-prefix and configure an ingress realm addr-prefix to an address that is not 0.0.0.0. C. Configure the al low-anonymous parameter under the sip-port to agents-only, then configure your SIP peers as session agents. D. Configure the access-control parameter to realm-prefix. E. Configure the allow-anonymous parameter to source-realm.
