NEW QUESTION # 78
As shown in the figure, the GEO/0/0 and GEO/0/1 interfaces of RTA are respectively connected to departments 1 and 2, and their network segments are respectively 10.1.2.0/24 and 10.1.3.0/24, which are restricted departments Between 1 and 2, deploy traffic-filter on RTA, which of the following deployment methods is correct? (Multiple choice)

A. Configure ACL3000 to reject the traffic whose source is 10.1.2.0/24 and whose destination is 10.1.3.0/24, call the traffic-filter in the inbound direction on G0/0/0 to call ACL3000
B. Configure ACL3000 to reject the traffic whose source is 10.1.3.0/24 and destination is 10.1.2.0/24, and call the traffic-filter in the inbound direction on GE0/0/1 to call ACL3000
C. Configure ACL3000 to reject the traffic whose source is 10.1.2.0/24 and whose destination is 10.1.3.0/24, call the traffic-filter in the outbound direction on GE0/0/1 to call ACL3000
D. Configure ACL3000 to reject the traffic whose source is 10.1.3.0/24 and whose destination is 10.1.2.0/24, call the traffic-filter in the outbound direction on GE0/0/0 to call ACL3000

Answer: C,D

NEW QUESTION # 81
Which of the following descriptions of the router's LSA processing principles are correct? (Multiple choice)

A. If the received LSA is damaged, such as Checksunm error, the LSA will not be received.
B. If multiple instances of an LSA are received, the highest priority is to check whether the checksums are the same. If they are not the same, the larger one is preferred.
C. If the router receives an LSA that is not available locally, it updates the LSDB and uses DD messages to flood the LSDB.
D. If an LSA already exists in the local LSDB of the router and an updated LSA is received at this time, the local LSDB will be updated and the updated LSA will be flooded out.

Answer: A,C

NEW QUESTION # 82
Four routers run IS-IS and have established adjacencies. The area IDs and router levels are marked in the following figure. R1 and R2 are connected through a PPP link, and R3 is the DIS. Which of the following statements are true?

A. If R2 sends a Level-2 LSP, R3 needs to send a PSNP for acknowledgment.
B. If R1 sends an LSP, R2 needs to send a PSNP for acknowledgment.
C. R3 periodically sends CSNPs to implement Level-2 LSDB synchronization.
D. R2 sends an LSP to R3 and R4 in unicast mode.

Answer: B,C

Explanation:
R3, as the DIS in the Level-2 domain, periodically sends Complete Sequence Number Protocol Data Units (CSNPs) to ensure LSDB synchronization among Level-2 routers.
R1 and R2 are in a Level-1 domain, and IS-IS requires the receiving router (R2) to acknowledge an LSP from R1 by sending a Partial Sequence Number Protocol Data Unit (PSNP).
IS-IS LSPs in a broadcast network are sent using multicast, not unicast, making option C incorrect.
For Level-2 LSPs, acknowledgments are not provided using PSNP by R3; CSNPs are sufficient for synchronization .
