Which type of address prefix in the following options indicates that the address is globally unique and globally routable among Pv6 unicast addresses, similar to the public network address in P4?

• A.FC00::/7
• B.::1/128
• C.2000::/3

RSTP provides different protection functions in different scenarios. Which statement is wrong? (Multiple choice)

• A.The designated port with root protection function enabled, its end [role can only remain as designated port
• B.After the BPDU protection function is activated on the switching device, if the edge port receives the RST BPDU, the edge port will be set as a non-edge port, and the spanning tree calculation will be performed again
• C.Enable the designated port of root protection. When the port receives a better RST BPDU, the port will enter the Discarding state and no longer forward packets. If the port does not receive a better RST BPDU within a period of time, it will automatically return to the normal Forwarding state
• D.After the anti-TC-BPDU packet attack function is enabled, the number of times the switching device processes TC BPDU packets in a unit time can be configured

As shown in the figure, the A department of branch 1 can access the Internet, but the B department can only use the encrypted VPN to access the headquarters resources. You can configure the NAT policy on the export device so that department A can access the Internet and configure IPsec VPN (ESP protocol) for department B + tunnel mode method to allow it to access the headquarters.

• A.True
• B.False

In the following topology, R1 can access the Internet through R2 and R3. The EBGP connections are established between R1 and R2, R1 and R3. R2 and R3 belong to the same AS. The default route is advertised through BGP. The traffic that R1 is required to access the Internet is preferably R2. Which of the following practices can be achieved? (Multiple Choice)

• B.R2 specifies that the peer R1 sets the local priority to 150 in the export direction.
• C.R1 specifies that the peer R2 sets the local priority to 150 in the import direction.
• D.R2 specifies that the peer R1 sets the MED attribute to 150 in the export direction.
