A. False
B. True
正解：B

質問 2：
The value of OSPF and BFD linkage is? Radio
A. Does not affect OSPF neighbor status
B. Any change in BFD status is realized by detecting the BFD at the millisecond level, which correlates the OSPF state and realizes the purpose of OSPF rapid sensing link state
C. BFD packet transmission interval can reach the 100-second level, which is slower than the OSPF induction link state
D. OSPF's hello send interval is seconds, which is faster than BFD inductive link state
正解：B

質問 3：
D Class IP address range 239000-239255255,
What does 255 do? Radio
A. Any legitimate multicast traffic and multicast application can adopt this address
B. Link-local multicast address, where traffic that uses that address includes network control messages and that address range is only the multicast address segment used by the routing protocol
C. SSM multicast address, the multicast address segment is valid for the whole network
D. Locally managed multicast address, which is valid only locally
正解：D

質問 4：
IGMP SSMMapping is bound to multicast through a static multicast source, so that members of IGMPv1 and IGMP2 can also access the SSM multicast network. The following statement about IGMPSSMMapping is wrong? (Radio).
A. IGMP hosts can make SSM services run IGMPv3 on the multicast router socket connected to the network segment where the member host is located
B. If the IGMP SSM Mapping feature is not enabled, neither IGMPv1 nor IGMPv2 supports multicast for deploying SSM modules
C. IGMP SSM Mapping does not process reporting messages from IGMPv3 In order to ensure that the same network segment runs any version
D. The multicast address of the SSM is 232000~232255255255
正解：C

質問 5：
Deploying the ISIS protocol in an IPv6 environment is true in the following statement (radio).
A. In the same broadcast network. If each router supports both IPV4 and Pv6, the DISC of JPV4 and Pv6 must be the same device
B. By default, the DIS priority of broadcast network interfaces at Level-1 and Level-2 is 1 B In broadcast networks, the DIS priority for IPV4 and IPV6 can be set separately
C. IS-IS sient is configured under the finger port, this interface will not send ISIS packets, but will receive ISIS packet
正解：C
