How does the SIP registrar server maintain the registered user's information in its database?

• A.  by creating a location record, which is an association between the Call-ID and the User Agent (UA)Contact address
• B.  by querying a DNS server
• C.  by querying an ENUM server
• D.  by creating a binding, which is an association between a globally unique SIP URI and the User Agent (UA) Contact address
• E.  by creating a registration cache entry, which is an association between a layer 3 IP address and the User Agent (UA) Via address

To ensure proper operation of a Session Border Controller HighAvailability (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?

• A.  via the utility address parameters on the wancoml and wancom2 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 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
• D.  by setting the utility address and sec-gateway values to addresses in different subnets as the IP address configured on the wancom interfaces
• E.  by setting a unique address on the wancoml and wancom2 interfaces via the utilityaddress command

How doesthe Session Border Controller ensure that a pinhole is kept open for persistent communication to a SIP endpoint behind a NAT device?

• A.  by sending messages at a defined frequency
• B.  by issuing PINGs to the endpoint's NAT address
• C.  by sending Address Resolution Protocol (ARP) requests at a defined frequency
• D.  by changing the expires= parameter to a defined value in 200 OK responses to INVITEs
• E.  by changing the expires= parameter to a defined value in 200 OK responses to
  REGISTERs

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

• A.  It sends a periodic re-register command to each endpoint behind a NAT.
• B.  It creates a binding for the Address of Record (AOR) of an endpoint that is behind a NAT.
• C.  It sends SIP OPTIONS at increasing intervals to test if an endpoint behind a NAT device is still reachable.
• D.  It sends ICMP PNGsto dynamically learn the binding time of an endpoint behind a NAT device.
• E.  It creates a binding for the Address of Record (AOR) of an endpoint that is NOT behind a NAT.

Upon issuing the done command, you getan Error 409.
Which two options explain this error? (Choose two.)

• A.  The configuration element you are creating is corrupted.
• B.  You are trying to create an element with a unique identifier that already exists.
• C.  The element you are trying to save doesnot exist.
• D.  You are trying to create a second instance of a single-instance configuration element.
• E.  There is an internal server error.
