Regarding IPv6 over IP4(19) road, the following statement is correct
A. When configuring manual tunneling on the VRP platform, a Tunnel interface is generally created; When configuring automatic tunneling, a Vrua-Template interface is usually created
B. The 6to4 automatic tunnel requires the use of a specific IP6 address segment, and the assigned address segment is preceded by 3ffe::/16
C. The ISATAP tunnel determines the destination IPV4 address of the tunnel based on the destination IP6 address.
D. Automatic tunneling has great advantages over manual tunneling, and manual tunneling will be phased out
E. All automatic tunnels encapsulate data in the same way.
正解：C,E
質問 2：
The following description of BGP loop protection is correct: multi-select
A. Non-RR BGP routers do not announce any updates from IBGP peers to other IBGP peers
B. BGP routers do not announce any slaves. The EBGP peer comes to update the information to its EBGP peer
C. Any routing information from an IBGP peer is advertised to the other IBGP peers
D. Any update information received from the EBGP peer that contains its own AS number in the AS-PATH attribute is discarded via the AS-PATH attribute
正解：A,D
質問 3：
Assume that BGP/MPLSIPVVPN, OSPF, LDP, and static routing protocols are already enabled on the PE router.
Which of the following protocols need to enable GR on PE in order to get NSF functionality? (Multiple choice questions).
A. OSPF
B. MPLS LDP
C. Static circuit
D. BGP
正解：A,B,D
質問 4：
Because BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors, and routing policies between IBGP neighbors are not valid.
A. TRUE
B. FALSE
正解：B
質問 5：
Regarding the FTP protocol, is it correct in the description below?

B. In ftP-style, the client completes the initialization of the TCP session for control and data
C. FTP always uses a TCP session to transmit control information and data information
D. In ftP Activee, the server side tells the client which port it expects to send data on by commanding "PORT"
E. FTP always uses TCP port 21 to establish a data session and TCP port 20 to establish a control session
正解：B
