The customer's network looks like this:
HostA----GE0/0--MSR-1--S1/0---------S1/0--MSR-2--GE0/0----HostB
The WAN interfaces on the two routers are configured as follows:
MSR-1:
firewall enable
acl number 3000
rule 0 deny ip source 192.168.0.0 0.0.0.255
rule 5 permit ip
interface Serial1/0
link-protocol ppp
firewall packet-filter 3000 outbound
ip address 6.6.6.2 255.255.255.0
MSR-2:
interface Serial1/0
link-protocol ppp
ip address 6.6.6.1 255.255.255.0
Assuming that the IP address of HostA is 192.168.0.2/24, and the routing and other related interface configurations are correct, then _______. (Multiple choice)

On the MSR router, if you want to completely delete an obsolete file in the recycle bin, you can execute the ______ command.
