NO.71 Which of the following statements regarding IGMPv1 and IGMPv2 are true?

 
 
 
 

NO.72 CPU attack defense uses a multi-level security mechanism to implement hierarchical device protection. Match the following levels with the corresponding protection functions.

NO.73 BFD control packets are encapsulated in UDP packets for transmission. What is the destination port number of multi-hop BFD control packets?

 
 
 
 

NO.74 The AS_Path attribute records the numbers of all ASs that a route passes through from the local end to the destination in the vector order. If a BGP speaker advertises a route to an IBGP peer, it creates an empty AS_Path in an Open message. This prevents routing loops between ASs.

 
 

NO.75 As shown in the figure, VRRP is associated with a BFD session. When a backup device detects a fault through BFD, the backup device immediately assumes the master role after the Master_Down_Timer timer expires.

 
 

NO.76 The next hop address of the routing entry in the routing table must be on the same network segment as the address of its directly connected interface.

 
 

NO.77 Which of the following descriptions about OSPF is correct?

 
 
 
 

NO.78 Which of the following descriptions about OSPF route aggregation is incorrect?

 
 
 
 

NO.79 The prefix list (IP-Prefix List) can match the IP address prefix length and mask length at the same time because it has three parameters: less-equal-value, mask- length and greater-equal-value, so which of the following can correctly describe the relationship between these three parameters?

 
 
 
 

NO.80 Different packets need to be used in the process of establishing OPSF adjacency relationships, so please associate the following states with the packets used in that state.

NO.81 On the VRP platform, when we introduce OSPF routing to ISIS, if COST is not specified, the cost value will be set to 16 by default.

 
 

NO.82 Which of the following descriptions about OSPF is wrong?

 
 
 
 

NO.83 Regarding the default routes of each protocol, which of the following description is wrong?

 
 
 
 

NO.84 OSPF runs directly on the TCP protocol and uses TCP port number 179.

 
 

NO.85 Which of the following are the advantages of building a campus network using stacking and clustering technologies? (Multiple choice)

 
 
 
 

NO.86 Compress the 2001:0DBB:B8:0000:C030:0000:0000:09A0: CDEF address.___________ (if the answer contains letters, capitalize them.)

NO.87 Use the default-route-advertise command in OSPF to advertise the default route to the common OSPF area. When there is no default route in the area, use ____ to force the advertisement.

NO.88 As shown in the figure, the stateful inspection firewall forwards the packet because the packet matches the session status of the firewall.

 
 

NO.89 Drag and Drop Question
Huawei modular devices have multiple hardware modules that provide different functions. Match the following hardware modules with their functions.

NO.90 During daily troubleshooting, engineers may need to check some alarm information of the equipment. Run the termina10 command to open the terminal display debugging/log/alarm information function sent by the information center.

NO.91 Two level-1 routers in different areas can form neighbor relationships.

 
 

NO.92 The output information of a certain router is shown in the figure:
<R1>display ospf peer
OSPF Process1 with Router ID 10.0.2.2
Neighbors
Area 0.0.0.0
interface10.0.12.2
