NEW QUESTION 137
As shown in the figure, four MSR routers are connected via Ethernet and serial interfaces, and OSPF is running in the network at the same time. The area is divided as shown in the figure.
It is known that the OSPF Cost value of all interconnection links is the same, except that the link between RTB and RTC is PPP, the other interconnection links are all Ethernet. So ______ . (Multiple choice)
- A. If the link between RTD and RTC fails, RTD and RTC will immediately send LSA summary information to RTA and RTB without waiting for a fixed LSA update cycle
- B. After the state is stable, the four routers have the same LSDB
- C. There are at least three BDRs in the network
- D. There are at least three DRs in the network
Answer: A,C,D
NEW QUESTION 138
Three MSR routers are connected in the same LAN network, as shown in the figure. Run OSPF on the LAN interconnection network segment of the three routers, and the DR priorities of RTA, RTB, and RTC are 2, 2, and 3 respectively.
Due to the failure of the RTC LAN link, only RTA and RTB are currently working normally, and the OSPF neighbor status between RTA and RTB is stable. So _____ . (Multiple choice)
- A. After the RTC link is restored, 3 OSPF adjacencies will be established in the network
- B. After the RTC link is restored, two OSPF adjacencies will be established in the network
- C. After the RTC link is restored, the OSPF adjacency status of RTC and RTB is FULL
- D. After the RTC link is restored, the DR will be reselected in the network, and the RTC will become the new DR
Answer: A,C
NEW QUESTION 139
The correct statement about STP, RSTP and MSTP is ______. (Multiple choice)
- A. RSTP is an optimized version of the STP protocol. The delay for the port to enter the forwarding state is greatly shortened under certain conditions, which shortens the time required for the network to finally reach topological stability.
- B. MSTP is compatible with STP and RSTP.
- C. STP cannot converge quickly. When the network topology changes, the originally blocked port will need to wait for a period of time before it becomes the forwarding state.
- D. MSTP can make up for the shortcomings of STP and RSTP. It can not only converge quickly, but also enable the traffic of different VLANs to be forwarded along their respective paths, thereby providing a better load sharing mechanism for redundant links.
Answer: A,B,C,D
