Demo Questions

Question 1
An engineer uses two routers to test IPv6 services, and simulates the interconnection between the headquarters and branches by running BGP4+. The logical topology of the network is shown in the figure. Regarding the transmission of IPv6 routes between the two devices, which of the following Is a statement wrong?
 
  1. The Next_Hop attribute must be an IPv6 global unicast address when routing
  2. BGP4+ transmits routing information between peers through Update packets
  3. If the MP_REA, CH_NLRI attribute is carried in the Update packet, it indicates that the advertisement is a reachable route 
  4. When the route is transmitted, it will carry recognized mandatory attributes such as AS_Path
Correct answer: A
Question 2
Which of the following regular expressions can match only BGP routes that pass through AS200 and then through AS300 eyes?
  1. 200$|300$
  2. A200|A300
  3. _(200 300)_
  4. _[200 300]
Correct answer: C
Question 3
As shown in the figure, Sitel and Site2 need to achieve mutual access through the operator's BGP/MPLS IPVPN. A known
The public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PF1 has
The 192.168.1.0/24 network segment route is advertised to PE2 through the MP.JIBGP neighbor relationship, and the route learning is normal. When grabbing between P and PE1, when Site2 accesses the 192.168.1.0/24 data of Sitel, the outermost label
What should the sign be?
 
FEC In/Out label
1.1.1.1/32 6662/3
  1. 6661
  2. 6662
  3. 8888
  4.  
Correct answer: C
Question 4
BFDLink state detection at the heart (millisecond) level can be achieved.
  1. right
  2. wrong
Correct answer: A
Question 5
Which of the following statements about the multicast address used by 0SPFv3 is correct?
  1. DR routers use FF08::6
  2. All 0SPF routers use FF08: 5
  3. All 5PF Routers use FF02:5
  4. DRThe router uses FF02::6
Correct answer: CD
Question 6
by executing___________The command can completely isolate the second and third layer users of different ports on the same LAN and cannot communicate. (Please use English and lowercase letters to complete the command, and the command cannot be abbreviated)
  1. portisolateenable
Correct answer: 1
Question 7
As shown in the figure, an engineer uses 4 routers to test branch network interoperability. Among them, R1, R2, and R3 in branch 1 deploy OSPF to implement network interoperability. R2, R3, and R4 in branch 2 deploy IS-S to implement network interoperability. Now the engineer wants to implement R1 to access the loopback interface address of R4. Which of the following operations can meet this requirement?
  
  1. existR2ofOSFFprocess neutralizationIS-ISDuring the process, the default route is advertised separately
  2. No configuration required
  3. only atR2ofIS-ISDuring the process, the default route is advertised
  4. only atR2ofOSPFDuring the process, the default route is advertised
Correct answer: A
Question 8
The IS-IS Level-1 neighbor relationship between R3 and R4 is not established. According to the information in this figure_What is the possible reason?
  
  1. R3andR4the interconnect interfacecircuit-typeMismatch
  2. R3andR4different area codes
  3. R3andR4ofIS-LevelMismatch
  4. R3andR1ofIIHAuthentication failed
Correct answer: B
Question 9
SFFv2 is an IGP running on an IPv4 network: 0SPFV3 is an IGP running on an IPv6 network. Compared with 0SPFV2, SPFV3 has a similar LSA type, but has slightly different functions. Which of the following is not included in the LSA type of 0SPFV3?
  1. AS-External-LSA
  2. Router-LSA
  3. ASBR-Summary-LSA
  4. Network-LSA
Correct answer: C
Question 10
Which of the following operations is not part of the middle stage of dissection?
  1. field defense
  2. cutover implementation
  3. Cutover preparation
  4. business test
Correct answer: D
