8. Suppose an MSR router obtains two routes to network 100.120.10.0/24, and the two routes are with costs 120 and 10, and preference values 10 and 150 respectively. Then the data packets destined for the network will ______.

10. The customer network is set up as follows: HostA----GE0/0--MSR-1--S1/0---------S1/0--MSR-2--GE0/0----HostB IP addresses and routes have been correctly configured in the network, and HostA and HostB can communicate with each other. Configure an ACL to prevent HostB from pinging HostA while HostA can ping HostB and all other communication between HostA and HostB are normal. Which of the following statements are TRUE?
A. Configuring the ACL only on MSR-1 cannot satisfy the requirements.
B. Configuring the ACL only on MSR-2 cannot satisfy the requirements.
C. Configuring the ACL only on MSR-1 can satisfy the requirements.
D. Configuring the ACL only on MSR-2 can satisfy the requirements.
E. When the ping command is executed, ICMP packets are transmitted bidirectionally. Therefore, the requirement for unidirectional communication cannot be satisfied.
