• Question 722:

  Which two characteristics are benefits of MPLS LDP lossless MD5 session authentication? (Choose two.)

  A. It allows for asymmetric passwords.
  B. It uses the MPLS LDP targeted hello, which is authenticated, instead of the regular MPLS LDP hello, which cannot be authenticated.
  C. It allows you to achieve or change LDP MD5 session authentication without interrupting the LDP session.
  D. It uses the MD5 method, which is a more secure authentication method than traditional MPLS LDP authentication, which uses a cleartext method.
  E. It enables authentication for UDP MPLS LDP discovery packets as well as TCP MPLS LDP label exchange sessions.
  A. It allows for asymmetric passwords.
  C. It allows you to achieve or change LDP MD5 session authentication without interrupting the LDP session.

• Question 726:

  Drag and drop the Timing Protocol characteristics on the left onto the correct Timing over Packet Solution on the right

  Select and Place:

  

  

  ---

  1.

  Network Time Protocol : The most recent version introduced accuracy to the terms of microseconds and includes an extensibility mechanism

  2.

  Precision Time Protocol : It defined a protocol for precise, real-time, network-wide synchronizaton accuracy in the sub millisecond range

  3.

  Synchronous Ethernet : It provides accurate frequency synchronization, but does not provide time/phase synchronization

  4.

  Time over IP connection and transfer of clock BOF: It was written to provide a roubust IP/MPLS-based time and frequency distribution architecture

• Question 727:

  Which option is a valid in-band method to map multicast flows to LSPs?

  A. PIM
  B. BGP auto-discovery
  C. BGP C-multicast
  D. mLDP extension to map multicast to LSP
  E. static
  D. mLDP extension to map multicast to LSP

• Question 728:

  Which type of multicast distribution trees can RSVP-TE-based multicast build?

  A. only branches of point-to-point tunnels
  B. multipoint-to-multipoint multicast from tail-end to head-end full mesh
  C. point-to-multipoint multicast distribution trees
  D. point-to-multipoint trees from tail-end to head-end
  E. multipoint-to-multipoint multicast distribution trees
  D. point-to-multipoint trees from tail-end to head-end

• Question 729:

  Refer to the exhibit.

  

  A company is deploying IPv6 using a dual-stack approach. OSPFv2 is used for IPv4 routing and is redistributed into the BGP IPv4 address family. The network engineer also needs to enable OSPFv3 for IPv6 routing using the same design

  that is used for OSPFv2. All prefixes in the OSPFv3 database must be redistributed into the BGP IPv6 address family at router R2, but R3 does not receive the loopback 0 IPv6 address of R2 via BGP.

  Which action will fix this problem?

  A. redistribution of BGP routes into OSPFv3
  B. redistribution of OSPFv3 routes into BGP with include-connected
  C. mutual redistribution of OSPFv3 and BGP routes
  D. redistribution of connected OSPFv3 routes
  B. redistribution of OSPFv3 routes into BGP with include-connected

• Question 730:

  An operations engineer must implement IPv6 multicast group address FF70::/12. Which two Cisco IOS XE configurations are needed to accomplish this task? (Choose two.)

  A. Apply the ipv6 pim command in all interfaces of all IPv6 routers in the IPv6 multicast domain.
  B. Apply the ipv6 pim bsr candidate rp command on the IPv6 routers that announce themselves as RPs and the ipv6 pim bsr candidate bsr command on mapping agent routers only
  C. Apply the ipv6 mld ssm-map enable and ipv6 mld ssm-map static command only on the RP IPv6 router.
  D. Apply the ipv6 multicast-routing command in all IPv6 routers in the IPv6 multicast domain.
  E. Apply the ipv6 pim rp-address command only on RP IPv6 router.
  D. Apply the ipv6 multicast-routing command in all IPv6 routers in the IPv6 multicast domain.
  E. Apply the ipv6 pim rp-address command only on RP IPv6 router.
