Question 1

Which two statements are true about a realm on the Session Border Controller?

A. It is a layer 5 abstraction of a VoIP network. B. It is a logical definition of a network or group of networks comprising devices that provide real-time communication. C. It can only have one steering poolport per realm. D. It is acollection of IP devices that perform IP routing functions. E. It is a layer 3 abstraction of a VoIP network.

Correct Answer: B,E

Question 2

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

Correct Answer: B

Question 3

You are examining a SIP packet. There is no final response to the ACK method.
What is the reason for this?

A. The ACK method is part of the INVITE transaction. B. The ACK method is an exception in RFC 3261. C. The ACK method was replaced with the CANCEL method in RFC 3261. D. The ACK method is an optional SIP method. E. The ACK method was defined only in RFC 2543and it has been deprecated.

Correct Answer: A

Question 4

Whichtwo statements are true about SIP response code handling on the Session Border
Controller? (Choose two.)

A. The Session Border Controller will originate a 503 when there are no steering pool ports available. B. The Session Border Controller cannot originate 3xx class redirect responses. C. The Session Border Controller can transmit a different SIP response code than it received. D. By default, the Session Border Controller will recurse on the 6xx messages. E. The Session Border Controller will originate a 403 response when bandwidth allocated to a realm has been exhausted.

Correct Answer: A,B

Question 5

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

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

Correct Answer: D

Question 6

What do you need to do to support ftp service on a media interface?

A. Add the IP address of the interface in the hip-ip-list and ftp-address parameters. B. Add the IP address of the interface in the hip-ip-list and telnet-address parameters. C. Set the hip-address parameter to enabled. D. Set the ftp-address parameter to enabled. E. Add the IP address of the remote device to the hip-ip-list and ftp-address parameters.

Correct Answer: D

Question 7

Your Session Border Controller is configured as the source and destination for all signaling messages and media streams coming into and leaving the provider's network.
Which two SIP functions does it provide? (Choose two.)

A. an IP edge router B. Back-to-Back User Agent (B2BUA) C. Data firewall D. Edge proxy E. Media gateway
