NEW QUESTION 224
The following descriptions about routing policies and policy routing are correct:
- A. The routing policy mainly controls the import, publication and reception of routing information

NEW QUESTION 225
The BGP protocol is an inter-domain routing protocol. The following description of the protocol is correct:
- A. It does not support neighbor authentication

NEW QUESTION 226
The following G about ISISIs R's description correct?
- A. ISIS GThe R feature is enabled by default.
- B. ISIS GR defines a whole new TLV structure to support this feature.
- C. ISIS GR notifies events and maintains neighbor relationships through CSNP messages.
- D. ISIS GR has a total of four timers.
Answer: B
Explanation:
Explanation
IS-ISGR (Graceful Restart) is a high-reliability technology that supports the GR capability, enabling uninterrupted data forwarding. Other devices in the area will perform routing calculations based on the new link state database, resulting in routing interruptions or routing loops.
IS-IS GThe R process is completed by the cooperation of GR-Restarter and GR-Helper. GR-Restarter: A device that is capable of GR and needs to perform GR.
GR-Helper: A device that has the GR capability and assists the GR device to complete the GR function.
GR-Restarter must have the ability of GR-Helper. To implement GR, IS-IS introduces TLV No. 211 (Restart TLV) andT1, T2, T3 three timers.
GR After the Restarter receives the CSNP from the Helper, it starts to synchronize the LSDB.
IS-In the extension of the GR capability of IS, three timers are introduced, namely T1, T2 and T3.

NEW QUESTION 228
Which of the following descriptions about ISIS' route penetration is correct?
- A. Route penetration by ISIS will not cause neighbor flapping.
- B. ISIS routing penetration can be deployed on routers at the level of Leve1-1.
- C. In the route infiltration of ISIS, the route before infiltration cannot be an aggregate route.
- D. ISIS's route penetration is used to prevent routing loops
- E. ISIS routing penetration can be used in an IPv6 environment.
Answer: A,E
NEW QUESTION 229
Regarding BGP4+, which of the following statements is correct?
- A. BGP4+ carries the prefix and mask length of IPv6 routes through the NLRI attribute
- B. BGP4+ carries the next hop address of the route through the Network Address of Next Hop in the MP_Reach_NLRI attribute
- C. BGP4+ carries the next hop address of IPv6 routes through the Next_hop attribute
- D. There is no Next_hop attribute in BGP4+
Answer: A,B
NEW QUESTION 230
As shown in the figure, which of the following statements is correct: (multiple choice))
- A. If R2 disables the BFD function, the BFD session of R1 will become down, which will cause the OSPF neighbor relationship to go down.
- B. OSPF BFD will be triggered only when the state becomes FULL session up
- C. if R2 Ethernet0/0/1 interface is down, then R1 BFD Sessions can quickly sense failures and notifyR1 make OSPF neighbor relationship down
- D. If R2 Ethernet0/0/1 interface down, then R1 arrive 10.0.2.2 The next hop of the route is changed to
10.0.12.2 - E. if R2Ethernet0/0/0 The interface is down, then R1 arrive 10.0.2.2 The next hop of the route is changed to 10.0.21.2

NEW QUESTION 232
OSPFAmong the five types of LSAs are used to transmit external routes, which of the following statements about the five types of LSAs is incorrect (single choice)
- A. existFive types of LSAs can be filtered by configuring corresponding filtering policies on ABR or ASBR.
- B. Five types of LSA by ASBR advertises and floods the OSPF network in non-Stub/NSSA areas
- C. The FA address is included in the five types of LSAs. The FA address is 0.0.0.0, which is only reserved and has no practical effect.
- D. A router in the same area as the ASBR can calculate the external route through the intra-area LSA and Category 5 1SA
Answer: C
Explanation:
Explanation
Five types of LSAs can be filtered by configuring the corresponding filtering policy on the ABR or ASBR.
an examinationTYPE 5Whether the FA address of the LSA is 0. If it is 0, it means that the route must go through the ASBR forwards, then preferably to ASBR metricshortest path. When there are multiple shortest paths, it is preferable to start from the larger area ID learned.
If the FA is not 0, the shortest path to the FA address metric is preferred, and the route to the FA must be intra-domain or inter-domain, otherwise the table is ignoreditem.
