  B. The dspload screen shows the expected traffic; the dsptrkutl screen shows actual traffic.
  C. The information on the dspload screen never changes; the dsptrkutl screen is dynamic
  D. The dspload screen shows historical information; the dsptrkutl screen shows current information.
  B. The dspload screen shows the expected traffic; the dsptrkutl screen shows actual traffic.

  Displays both the used and available bandwidth (both in the transmit and receive directions) for each trunk at the specified node. The "transmit" direction is from the node specified and to the node at the other end of the trunk. In the screen display, the numbers of disabled trunks appear in dim, reverse video on the screen.

  dsptrkutl Displays dynamic utilization information for a specified trunk. The trunk must be upped and added to use this command. The following lists the trunk utilization and terminated connection parameters included in the display. The parameter values are updated according to the specified or default interval and the screen remains displayed until the DEL key is depressed. Disabled trunks have their trunk number displayed in dim, reverse video on the screen.

• Question 223:

  Refer to the exhibit.

  

  Router A is configured with a BGP keepalive timer of 20 seconds and a BGP holddown timer interval of 60 seconds. The BGP peer router B is configured with 5 seconds of keepalive interval and 15 seconds of holddown timer interval. Which option is the value of the keepalive interval and holddown timers, respectively, after the successful BGP TCP negotiation between router A and router B?

  A. BGP TCP negotiation will not be successful.
  B. 20 and 60 seconds
  C. 5 and 15 seconds
  D. Router A will use 20 and 60 seconds and router B will use 5 and 15 seconds.
  E. Router B will use 20 and 60 seconds and router A will use 5 and 15 seconds.

• Question 224:

  Which statement about 6PE is true?

  A. An additional address family was added to MP-BGP for the support of 6PE.
  B. MP-iBGP is needed to support 6PE.
  C. LDP is needed to support 6PE.
  D. P routers need to be dual stack.
  E. MP-eBGP is needed to support 6PE.
  B. MP-iBGP is needed to support 6PE.

• Question 225:

  Which two options best describe the purpose of session ID and cookie field in a L2TPv3 packet?

  A. The session ID is a 32-bit locally significant field used to identify the call on the destination or egress tunnel endport. The session ID will be negotiated by the control connection or statically defined if using the L2TP v3 data plane only.
  B. The cookie is a variable length (with a maximum of eight bytes),word-aligned optional field. The control connection can negotiate this as an additional level of guarantee beyond the regular session ID lookup to make sure that a data message has been directed to the correct session or that any recently reused session ID will not be misdirected.
  C. The cookie is a 32-bit locally significant field used to identify the call on the destination or egress tunnel endpoint. The cookie will be negotiated by the control connection or statically defined if using the L2TPv3 data plane only
  D. The session ID is a variable length (with a maximum of eight bytes), word-aligned optional field. The control connection can negotiate this as an additional level of guarantee beyond the regular cookie lookup to make sure that a data message has been directed to the correct session or that any recently reused cookie will not be misdirected.

  Session ID:

  The 32-bit nonzero session ID carried in the data message header is used to associate incoming data messages with a particular local attachment circuit. Note that one L2TPv3 session corresponds to one pseudowire.

  Cookie:

  Following the session ID is an optional variable length random cookie value (maximum 64 bits). This cookie value can be used in addition to the session ID and adds an extra level of assurance that the incoming data messages are correctly

  associated with the local attachment circuit. Furthermore, a randomly chosen cookie provides protection against blind insertion attacks. That is, an attacker would find it very difficult, if not impossible, to insert packets into a data stream

  (pseudowire) if the attacker is unable to sniff packets transiting the network between peer LCCEs. This is because of the difficulty of guessing the correct cookie value (0 to 264 if the cookie is 64 bits in length).

• Question 226:

  What IOS commands display MPLS label mapping on an LSR?

  A. Show mpls ldp parameters
  B. Show mpls ldp bindings
  C. Show mpls forwading-table
  D. Show mpls ldp discovery
  E. Show mpls ldp neighbor detail
  B. Show mpls ldp bindings

• Question 227:

  The layer 2 protocol used by POS technology offers a standardized way for mapping IP packets into SONET/ SDH payloads. Select the correct sequence of POS operation:

  1) Data is scrambled and synchronous mapping takes place by octet into the SONET/SDH frame.

  2) Encapsulated via Point-to-Point Protocol (PPP) takes place framing information is added with High-level Data Link Control (HDLC).

  3) Gaps between frames are filled with flags, set to value 7E.

  4) Octet stuffing occurs if any flags or resultant escape characters (of value 7D) are found in the data.

  5) Data is segmented into an IP datagram with its 20-byte IP header.

  A. 1, 3, 4, 5, 2
  B. 5, 2, 3, 1, 4
  C. 2, 3, 5, 4, 1
  D. 5, 2, 3, 4, 1
  E. 1, 2, 3, 4, 5
  D. 5, 2, 3, 4, 1

  The proper order of operation of PoS is:

  When transmitting:

  IP -> PPP -> FCS generation -> Byte stuffing -> Scrambling -> SONET/SDH framing When receiving:

  SONET/SDH framing -> Descrambling -> Byte destuffing -> FCS detection -> PPP -> IP Remote

• Question 228:
