the Session Border Controller will not use the registration cache for routing

C.

all endpoints in the realm will be cached when registered

D.

only endpoints behind NAT in the realm will be cached when registered

E.

the Session Border Controller will never use the local-policy mechanism for routing

Question 2

You are adding peers to a Policy-Based Realm Bridging (PBRB) configuration.

Which two configuration steps, among others, are required? (Choose two.)

Options:

A.

Navigate to the media-manager configuration branch and configure the realm-config configuration element.

Navigate to the session-router configuration branch and configure the sipd-address configuration element.

C.

Navigate to the session-router configuration branch and configure the local-policy configuration element.

D.

Navigate to the session-router configuration branch and configure the sip-nat configuration element.

E.

Navigate to the media-manager configuration branch and configure the access-control configuration element.

Question 3

The Session Border Controller needs to be configured to act as a Back-to-Back User Agent (B2BUA).

How would you accomplish this?

Options:

A.

Navigate to the sip-config configuration element and set the operation-mode to stateless.

B.

Navigate to the sip-config configuration element and set the operation-mode to dialog.

C.

Navigate to the sip-config configuration element and set the operation-mode to stateful.

D.

Navigate to the session-router configuration element and set the operation-mode to dialog.

E.

Navigate to the session-router configuration element and set the operation-mode to none.

Question 4

You finished configuring a not Real Time Change (not RTC)-supported configuration element and you want to apply the change in your service.

Which two options are valid in order to accomplish this? (Choose two.)

Options:

A.

From user mode, execute the save-config and activate-config commands.

B.

From configuration mode, execute the save-config, activate-config, and reboot commands.

C.

From superuser mode, execute the save-config and activate-config and reboot commands.

D.

From superuser mode, execute the save-config and activate-config commands.

E.

From superuser mode, execute the save-config, activate-config, and reboot force commands.

Question 5

When provisioning the redundancy-configuration, the peer name for each of the peers in a High Availability configuration must also be defined in each system’s ______________.

Options:

A.

hostname parameter under the sip-config configuration element

B.

hostname parameter under the account-config configuration element

C.

hostname parameter under the bootparam configuration branch

D.

target name parameter under the bootparam configuration branch

E.

hostname parameter under the system-config configuration element

Question 6

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?

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

Question 7

Which three options are valid ways to apply Header Manipulation Rules (HMRs) to your existing configuration?

Options:

A.

Navigate to the network-interface configuration element and configure the in-manipulationid parameter.

B.

Navigate to the session-agent configuration element and configure the in-manipulationid parameter.

C.

Navigate to the sip-interface configuration element and configure the in-manipulationid parameter.

D.

Navigate to the session-agent configuration element and configure the in-manipulationid parameter.

E.

Navigate to the session-group configuration element and configure the in-manipulationid parameter.

Question 8

by changing the expires= parameter to a defined value in 200 OK responses to INVITEs

C.

by issuing PINGs to the endpoint's NAT address

D.

by sending Address Resolution Protocol (ARP) requests at a defined frequency
