Question 1

What does the Session Border Controller do when the Adaptive Hosted NAT (HNT) feature is enabled?

AIt sends a periodic re-register command to each endpoint behind a NAT.

BIt creates a binding for the Address of Record (AOR) of an endpoint that is behind a NAT.

CIt creates a binding for the Address of Record (AOR) of an endpoint that is NOT behind a NAT.

DIt sends SIP OPTIONS at increasing intervals to test if an endpoint behind a NAT device is still reachable.

EIt sends ICMP PNGs to dynamically learn the binding time of an endpoint behind a NAT device.

Correct Answer: C. It creates a binding for the Address of Record (AOR) of an endpoint that is NOT behind a NAT.

Question 2

You configured the Session Agent Group (SAG) element. You want the Session Agent to be selected in the order in which they are listed in the destination list, with each agent selected in turn, one per session.

How would you accomplish this?

ANavigate to the session-agent configuration element and set the strategy parameter to sequential.

BNavigate to the session-agent configuration element and set the strategy parameter to propdist.

CNavigate to the session-agent configuration element and set the strategy parameter to hunt.

DNavigate to the session-agent configuration element and set the strategy parameter to roundrobin.

ENavigate to the session-agent configuration element and set the strategy parameter to leastbusy.

Correct Answer: D. Navigate to the session-agent configuration element and set the strategy parameter to roundrobin.

Question 6

You are configuring steering pools. After executing the done command, you get this error message:

error 409 saving configuration SteeringPool.

Identify the cause of the error.

AThe realm-id parameter value of the steering-pool refers to a realm-config element that already exists in the configuration.

BThe ip-address parameter of the steering-pool has the same value as the address parameter of a sip-port configuration element.

CThe realm-id parameter value of the steering-pool refers to a realm-config element that does not exist in the configuration.

DAnother steering-pool configuration element with same ip-address, realm-id, start-port, and end-port parameters values already exists in the configuration.

EAnother steering-pool configuration element with same ip-address and realm-id but with different start-port and end-port parameters values already exists in the configuration.

Correct Answer: E. Another steering-pool configuration element with same ip-address and realm-id but with different start-port and end-port parameters values already exists in the configuration.

Question 9

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?

Aby 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

Bby 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

Cby setting the utility address and sec-gateway values to addresses in different subnets as the IP address configured on the wancom interfaces

Dby setting a unique address on the wancoml and wancom2 interfaces via the utility address command
