Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
set security zones application-override MY-HTTP port 8080
Why it's wrong here
Application-override is used for bypassing deep inspection, not defining basic port apps.
- ✗
set firewall family inet filter MY-FILTER term 1 then port 8080
Why it's wrong here
This is firewall filter syntax, not application definition syntax.
- ✓
set applications application MY-HTTP protocol tcp destination-port 8080
Why this is correct
This syntax correctly defines a custom TCP application on port 8080.
- ✗
set security applications MY-HTTP tcp port 8080
Why it's wrong here
This is incorrect hierarchy syntax.
