• Question 31:

  As shown in the figure, RTA, RTB, RTC are interconnected over IS-IS, RTA,

  RTD, RTE, and RTC are interconnected over OSPF. Both IS-IS and OSPF use the default costs. RSVPTE is enabled on all routers and the interfaces between these routers. The Loopback0 interface of RTC is 192.168.0.3/32 and is

  advertised in both OSPF and ISIS areas. 192.168.0.3/32 is also the LSR ID of MPLS. Configurations of the MPLS and tunnel on RTA:

• Question 34:

  Which statement about the Hub s MPLS VPN networking is false?

  A. The Hub PE can receive the VPN_IPv4 routes advertised by all Spoke PEs.
  B. When an MP-IBGB neighbor relationship is established between two spoke PEs, the value of the Import VPN Target attribute of one Spoke PE can be the same as tat of the Export VPN Target attribute of the other Spoke PE.
  C. The Hub PE advertises the routes learned from one Spoke PE to other Spoke PEs. Therefore, Spoke sites can access other through the Hub site.
  D. All Spoke PEs can receive the VPN-IPv4 routes advertised by the Hub PE.
  B. When an MP-IBGB neighbor relationship is established between two spoke PEs, the value of the Import VPN Target attribute of one Spoke PE can be the same as tat of the Export VPN Target attribute of the other Spoke PE.

• Question 35:

  As shown in the figure, the mapping between links and administrative groups is as follows:

  0x0F for A -> B; 0xFF for B -> C; 0xF0 for A -> C; 0xC3 for B -> D; and 0x3C for C -> D.

  It is expected to configure a tunnel (affinity: 0x0C; mask: 0xFF) on node A to connect to RTD. Which path will be created along with the tunnel?

  A. A -> C -> D
  B. A -> B -> D
  C. A -> C -> B -> D
  D. A -> B -> C -> D
  E. No path will be created.
  D. A -> B -> C -> D

• Question 36:

• Question 37:

  Exhibit.

  

  RTA is an edge router of the MPLS backbone network. It provides the access services for users under Layer 2 switches and different users by subinterface . User A access VLAN 12 and has subscribed to the His, VoIP, and IPTV services. According to 802 1p priorities, the value indicates the His service, 1 indicates the VoIp service, and 4 indicates the IPTV service. RTA is configured on he access side as follows.

  

  What is the descending order of service priorities?

  A. VoIP, IPTV, HSI
  B. HSI, VoIP, IPTV
  C. IPTV, VoIP, HSI
  D. HSI, IPTV, VoIP
  D. HSI, IPTV, VoIP

• Question 38:

  In the access architecture of an IP bearer network, the OSPF protocol is enabled between two access routers, two firewalls (in transparent mode), and two Layer 3 switches. Softswitches work in active/standby mode. VRRP is enabled between the softswitches to provide a gateway. In normalcases, SW1 is the master router and SW2 is the backup router. Considering the reliability of the access network, how would you plan the cost value of each link in the OSPF area?

  A. a=b=c=d
  B. c>a+b+d
  C. d>a+b+c
  D. a=b>c=d
  C. d>a+b+c
