Cisco 350-029 Online Questions & Answers

• Question 101:

  Which four statements about the Carrier Supporting Carrier (CSC) feature are true? (Choose four.)

  A. MPLS is required between the PE and CE routers that connect the backbone carrier to the customer carrier.
  B. The backbone carrier must enable the PE router to check that the packets it receives from the CE router contain only the labels that the PE router advertised to the CE router.
  C. Every packet that crosses the backbone carrier must be encapsulated so that the packet includes MPLS labels
  D. AII PE routers that link the backbone carrier to the customer carrier must run Route Target Rewrite.
  E. A routing protocol is required between the PE and CE routers that connect the backbone carrier to the customer carrier. The routing protocol enables the customer carrier to exchange IGP routing information with the backbone carrier.

  B. Loose path is not supported in P2MP TE.
  C. Multiple IP multicast groups can map to one P2MP tunnel.

  4.1.9. What's new in Version 4?

  According to the NTP Version 4 Release Notes found in release.htm, the new features of version four (as compared to version three) are.

  Use of floating-point arithmetic instead of fixed-point arithmetic. Redesigned clock discipline algorithm that improves accuracy, handling of network jitter, and polling intervals.

  Support for the nanokernel kernel implementation that provides nanosecond precision as well as improved algorithms.

  Public-Key cryptography known as autokey that avoids having common secret keys.

  Automatic server discovery (manycast mode)

  Fast synchronization at startup and after network failures (burst mode) New and revised drivers for reference clocks Support for new platforms and operating systems

• Question 107:

  Which statement about SNMP is true?

  A. SNMP version 2 uses a proxy agent to forward GetNext message to SNMP version 3.
  B. SNMP version 2 supports message integrity to ensure that a packet has not been tampered with in transit.
  C. Proxy agents were used only in SNMP version 1.
  D. SNMP version 3 supports encryption and SNMP version 2 support authentication.
  E. GetBulk messages are converted to GetNext messages by the proxy agent and are then forwarded to the SNMP version 1 agent.
  E. GetBulk messages are converted to GetNext messages by the proxy agent and are then forwarded to the SNMP version 1 agent.

  Proxy agents:

  A SNMPv2 agent can act as a proxy agent on behalf of SNMPv1 managed devices, as follows:

  A SNMPv2 NMS issues a command intended for a SNMPv1 agent. The NMS sends the SNMP message to the SNMPv2 proxy agent. The proxy agent forwards Get, GetNext, and Set messages to the SNMPv1 agent unchanged. GetBulk

  messages are converted by the proxy agent to GetNext messages and then are forwarded to the SNMPv1 agent.

  The proxy agent maps SNMPv1 trap messages to SNMPv2 trap messages and then forwards them to the NMS.

  SNMPv3 provides important security features:[11]

  Confidentiality - Encryption of packets to prevent snooping by an unauthorized source. Integrity - Message integrity to ensure that a packet has not been tampered while in transit including an optional packet replay protection mechanism.

  Authentication - to verify that the message is from a valid source.

  C. RIP version 2
  D. IS-IS
  E. EIGRP
  A. OSPF
  D. IS-IS

• Question 109:
