Exhibit:



As shown in the figure, RTA belongs to AS 100 and has an EBGP neighbor relationship with RTC, RTD, and TTB is an IBGP neighbor of RTC, RTD, and RTE, and the four router all belong to AS 200. (
Note: The attributed not involved In the question use the default values)
1. Import route 1.1.1/32 from RTA and advertise this route to RTB by way of RTC, RTD, and RTE, respectively (suppose the three routers between is IGP, EGP, and INCOMPL:ETE, respectively.
Which route will RTB prefer?

2. Suppose the preceding policy is retained. Apply inbound routing policies on RTC, RTD, and RTE so that the values of the MED attribute of route 1.1.1.32 learned by RTB are 40, and 20 respectively.
Which route will RTB prefer?
3. Suppose the preceding policy is retained. Apply an inbound routing policy on RTB so that the values of the AS_ PATH attribute of route 1.1.1.1/32
Learned from RTC, RTD, and RTE are 10 20 30,and 10 20, respectively.
Which route will RTB prefer?
4. Suppose the preceding policy is retained. Apply an inbound routing policy on RTB so that the values of the local-preference attribute of route 1.1.1.1.32 learned from RTC and RTE are 30 and 120 , respectively.
Which route will RTB prefer.
5. Suppose the preceding policy is retained. Apply inbound policies on RTC. RTD and RTE so that the values of the preferred-value attribute of route 1.1.1.132 are 50.40 and 30 respectively.
Which route will RTB prefer?

  1. RTC. , RTC, RTE, RTC, RTE
  2. RTC, RTD, RTD, RTE. RTE
  3. RTC, RTC, RTD, RTC, RTE
  4. RTC, RTC, RTD, RTE, RTE

Answer(s): A



Exhibit:



As shown in the figure, RTA and have one BGP session. To detect fault fast, the BFD for BGP feature needs to be configured on RTA and RTB. BGP-related configurations are as follows:



The only Ethernet link between RTA and RTB becomes faulty when the BGP neighbor session is in ESTABLISHED state and the BFD session is in the UP state.
Which statements is true? (
Note: BFD works in asynchronous mode)

  1. RTA detect the fault faster than RTB.
  2. The BGP session between RTA and RTB is interrupted when the BGP hold time (time duration is 180s by default) express.
  3. RTB detect the fault faster than RTA.
  4. RTA and RTB detect the fault simultaneously.

Answer(s): C



Exhibit:



As shown in the figure, virtual private LAN service (VPLS) is enabled on routers PE 1 and PE 2.CEs are connected to PEs through QinQ and PC A and PC B are connected to the two CEs. The two PCs belong to the same VPN and can communicate with each other properly.
Which of the following statements about the communication process when you ping PC B from PC A are true?

  1. PE 1 receives packets with a VLAN tag from CE 1 and adds a VLAN tag to these packets.
  2. If the penultimate hop popping (PHP) feature of MPLS is enabled on PEs, a packet received by PE 2 from a P router has two VLAN tags one MPLS label.
  3. PE 1 add two MPLS labels to a packet before sending the packet to a router.
  4. A packet received by CE 2 from PE 2 has two VLAN tags CE 2 removed the outer tab and forwards the packets to PC B based on the inner tag

Answer(s): A,B,C



Exhibit:



As shown in the figure, Super VLAN is enabled on SWA (a LAN switch). The Super VLAN configuration is as follows:



Which of the following specifics the time order in which the preceding debugging information is generated?

  1. 3--4--1--2
  2. 1--2--3--4
  3. 1--4--2--3
  4. 3--2--1--4

Answer(s): D
