質問 9

Compress the 2001:0DBB:B8:0000:C030:0000:0000:09A0:CDEF address.___________(if the answer contains letters, capitalize them.)

正解：

2001:DBB:B8:0:C030::9A0:CDEF
Explanation:
The IPv6 address 2001:0DBB:B8:0000:C030:0000:0000:09A0:CDEF can be compressed by removing leading zeros in each segment and collapsing consecutive zero groups into ::. The result is 2001:DBB:B8:0:
C030::9A0:CDEF .

質問 10

IGMP group entries play an important role in multicast forwarding. An administrator runs a command to view information about a multicast entry. The information is as follows:
sql
Copy
<HUAWEI> display igmp group
Interface group report information
Vlanif100(10.1.6.2):
Total 1 IGMP Group reported
Group Address Last Reporter Uptime Expires
225.1.1.2 10.1.6.10 00:02:04 00:01:17
Given this, which of the following statements are true?

（A）This entry can be used to construct the corresponding (S, G) entry.

（B）Expires indicates the aging time of the IGMP group.

（C）This entry is created when the device receives an IGMP Join message from a user.

（D）225.1.1.2 is the address of the group that the user joins.
