Which command will apply a policy to redistribute static routes into OSPF?

[edit firewall family inet filter input-filter]
user@router# show
term my-policy {
from {
source-address {
151.43.62.0/24;
}
}
then {
count;
}
}
term else {
then {
discard;
}
}

Which two tasks are accomplished by the firewall filter shown in the exhibit? (Choose two.)

[edit policy-options]
user@router# show
policy-statement my-policy {
term 1 {
from {
route-filter 172.27.0.0/24 longer;
}
}
then reject;
}

Which statement is correct about the policy shown in the exhibit?

policy-options {
policy-statement example-pol {
term 1 {
from {
protocol static;
route-filter 10.1.0.0/16 exact;
}
then {
preference 6;
accept;
}
}
term 2 {
from {
protocol static;
route-filter 10.1.1.0/24 longer;
}
then {
preference 7;
accept;
}
}
term 3 {
from {
protocol static;
route-filter 10.1.0.0/16 upto /24;

}
then {
preference 8;
accept;
}
}
term 4 {
then accept;
}
}
}

Referring to the exhibit, if the static route with prefix 10.1.1.0/24 is evaluated against the routing
policy, which preference value will be set?

[edit policy-options]
user@router# show
policy-statement block-routes {
term 1 {

from {
route-filter 172.27.0.0/24 longer;
}
then reject;
}
term 2 {
then accept;
}
}

You are asked to ensure that your device does not accept any prefixes within the 172.27.0.0/24
network. You have applied the policy shown in the exhibit, but the 172.27.0.0/24 route is still
present on your device.
Which configuration will resolve this problem?
