Question 1

What configuration step is required for booting the Session Border Controller from an external FTP server?

  1. Navigate to the bootparams configuration branch and set the host inet field to the IP address of the external BOOTP Server from which the Session Border Controller can boot.
  2. Navigate to the system configuration branch and set the ip address field of the wancom1 management interface.
  3. Navigate to the bootparams configuration branch and set the ip address field of the destination SIP device with which the Session Border Controller needs to interact.
  4. Navigate to the system configuration branch and set the ip address field of the wancom0 management interface.
  5. Navigate to the bootparams configuration branch, set the host inet or Host IP, FTP username, and FTP password for the external FTP Server in

Question 2

You are configuring access rules in a Session Border Controller Peering architecture. Which configuration step is required to allow access from any User Agent (UA)?

  1. Navigate to the sip-port configuration element and set the allow-anonymous parameter to all.
  2. Navigate to the realm-config configuration element and set the addr-prefix parameter to the IP subnet of your trusted User Agent (UA).
  3. Navigate to the sip-port configuration element and set the allow-anonymous parameter to address-prefix.
  4. Navigate to the session-agent configuration element and set the ip-address parameter to the IP subnet of your trusted User Agent (UA).
  5. Navigate to the sip-port configuration element and set the allow-anonymous parameter to agents-only.

Question 3

Which two functionalities are provided by Session Border Controllers? (Choose two.)

  1. they span multiple networks and provide edge proxy functions between them
  2. they are session-aware devices that enable control of end-to-end interactive communications across PSTN network borders
  3. they enable premium interactive services across IP network borders by complementing existing edge routers
  4. they provide routing functions for IP, TCP, and SMTP using application parameters.
  5. they replace typical edge routers and firewalls in order to provide a unified network border for signaling and media control

Question 4

What mechanism is used to ensure adjacent devices can redirect their Ethernet traffic to the Session Border Controller that takes over, when a Session Border Controllers fails over?

  1. Gratuitous ARP
  2. Reverse ARP
  3. Proxy ARP
  4. HSRP
  5. BOOTP

Question 5

Which three statements are true about SIP, per RFC 326? (Choose three.)

  1. SIP does not provide for resource reservation.
  2. SIP defines native methods for negotiating media streams.
  3. A SIP transaction occurs between a client and a server.
  4. To set up a voice session, SIP relies on protocols such as SDP and RTP.
  5. SIP signaling can only be used for voice over IP thereby limiting its use as a general signaling protocol.
