An administrator attempts to add the following rule to ACL 2001 on R1:[R1] acl 2001[R1-acl4-basic-2001]...

ACL 2001 is a basic IPv4 ACL because Huawei numbered basic ACLs use the range 2000 to 2999. A basic ACL can match relatively simple conditions such as source IP address and an effective time range, but it does not support matching the IP protocol, destination IP address, or TCP/UDP source and destination port numbers. The attempted rule includes tcp, destination-port eq telnet, and a destination network, all of which require an advanced ACL. Huawei advanced ACLs use the 3000 to 3999 range and can match protocol type, source and destination addresses, and Layer 4 port values. Therefore, even after correcting the obvious command typo from ad 2001 to acl 2001, the rule syntax is still incompatible with a basic ACL 2001 and cannot be successfully configured in that ACL view. To implement the intended policy, the administrator should create an advanced ACL and express the TCP Telnet and destination conditions there. Consequently, the statement that the rule cannot be configured successfully is TRUE, option A.
