Quick Answer
The correct final step is to save the configuration with copy running-config startup-config. This order is correct because named ACL modification using sequence numbers allows you to insert or delete individual entries without removing the entire ACL, but any changes made in running-config are volatile until written to NVRAM. On the ENCOR 350-401 exam, this drag-and-drop task tests your understanding of the precise workflow: first view current entries with show access-lists, then delete the old entry using no sequence-number, insert the new entry with a specific sequence number, verify the change, and finally save. A common trap is forgetting that sequence numbers are optional when adding but required for targeted deletion, and that verification must occur before saving to confirm the new rule is correctly positioned. Memory tip: think "View, Delete, Insert, Verify, Save" as the five-step rhythm—like a surgical edit where you never close the file until you’ve double-checked the fix.

Correct answer & explanation
✓
Display ACL with show access-lists
Named ACLs can be modified by inserting or deleting entries by sequence number. The correct order is: view current entries, delete the old entry, insert the new entry with a sequence number, verify, then save.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related 350-401 ACL questions on filtering logic and placement.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop the steps of named ACL modification using sequence numbers into the correct order, from first to last.
medium- ✓ A.View current ACL with 'show access-list'
- ✓ B.Identify desired sequence number for insertion
- ✓ C.Enter ACL configuration mode with 'ip access-list extended'
- ✓ D.Insert new entry with sequence number
- ✓ E.Verify updated ACL with 'show access-list'
Why A: Sequence numbers allow editing named ACLs without re-entering all entries. The correct order is: view current entries, insert a new entry at a specific sequence, then verify the updated ACL.
