Question 46

Regarding the difference between NSR and NSF, which is correct?

A.NSF has to rely on neighbor routers to complete

B.NSF does not require neighbor routers to complete

C.Both NSR and NSF require neighbor routers to complete

D.NSR must rely on neighboring routers to complete

Question 47

uninterrupted forwardingNSF (Non-Stopping Forwarding) and nonstop routing NSR (Non Stopping Routing) are two solutions for high reliabilitysolution, which of the following statements is correct

A.NSR standby routers need to negotiate the ability to support NSR through specific packets

B.NSRAfter this is enabled, if the main control board fails before the batch backup of services is completed, the NSR switchover cannot be completed.

C.NSF routers do not need to negotiate the ability to support NSF through specific packets

D.turn onNSFAfter that, the router is switched between active and standby, and the routing table and forwarding table remain unchanged, so the traffic will not be lost during the GR time.

Question 48

About BGP/MPLS IP VPN Routing interaction, which of the following descriptions is wrong?

A.The egress PE can use BGP, IGP, or static routes to CE sends IPv4 route

B.Ingress PE will be the IPv4 routes received by the CE become VPNv4 routes and are saved according to different VPN instances

C.exit after the PE receives the VPNv4 route advertised by the ingress PE, it filters the VPNv4 route according to the RT attribute carried by the route.

D.PE and CEs exchange IPv4 routing information

Question 49

IGMP SSM Mapping statically binds the multicast source to the multicast group, so that the group members of IGMPv1 and IGMPv2 can also access the SSM multicast network. Which of the following statements about IGMP SSM Mapping is false?

A.IGMP SSM Mapping does not process IGMPv3 report packets. In order to ensure that hosts running any version of IGMP on the same network segment can obtain SSM services, it is necessary to run IGMPV3 on the interface of the multicast router connected to the network segment where the member hosts are located.

B.If the IGMP SSM Mapping. function is not enabled, neither IGMPv1 nor IGMPv2 supports the deployment of multicast in SSM mode

C.The address of the multicast group of SSM is 232.0.0.0~232.255.255.255

D.Statically configure the mapping rules of SSM addresses on the IGMP querier, and map the group join information in the IGMPv1 or IGMPv2 member report to the group leave information

Question 50

an existing switch is running RSTPprotocol. If the network topology changes, what will happen to the Layer 2 forwarding entries automatically learned by the switch?

A.Except for the entry related to the edge port, which is not deleted, all other entries are deleted.

B.If the aging time is set to 16 seconds, then the entries that exceed the time will be deleted

C.In addition to entries related to edge ports and receivedTCExcept that the port-related entries of the message are not deleted, other entries are deleted.

D.only with receivedTCOnly the entry related to the port of the message will be deleted.
