PCNSA Managing Objects Practice Question
An administrator needs to create a service group for a custom application that uses TCP ports 1000 and 2000. Which two methods will successfully create a service group that can be used in a single security rule? (Choose two.)
⚠ Common exam trap
Many exam-takers confuse a service group with a port range object, assuming that a range like 1000-2000 is equivalent to specifying only the endpoints, but in reality, it includes every port in between.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a service group with two service objects (one for 1000, one for 2000)
A service group in Palo Alto Networks firewalls can contain multiple service objects, allowing you to combine TCP ports 1000 and 2000 into a single group that can be referenced in one security rule. This enables the firewall to match traffic to either port within the same rule, simplifying policy management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a service object with port range 1000-2000
Why it's wrong here
This would allow all ports between 1000 and 2000, not just the two specific ports.
- ✗
Create a service object with port 1000 and use an application override
Why it's wrong here
Application override does not create a service group; it reclassifies traffic.
- ✓
Create a service group with two service objects (one for 1000, one for 2000)
Why this is correct
This groups the two service objects into a single group for use in a rule.
- ✓
Create a custom application that includes both ports
Why this is correct
A custom application can define multiple ports and be used in a single rule.
- ✗
Create a single service object with port 1000 and a separate rule for port 2000
Why it's wrong here
This requires two rules, not a single rule.
