Question 1mediummatching
Study the full ACL explanation →Question 145 of 2,015
Quick Answer
The correct matching pairs are: sequence-number assigns a numeric identifier to the ACL line for insertion or deletion, permit allows the packet, deny discards the packet, remark adds a comment, and log generates a log message for matched packets. This mapping is fundamental to understanding how ACL actions determine packet processing outcomes, where permit and deny directly control traffic flow while sequence-number enables precise editing within named ACLs. On the ENCOR 350-401 exam, this drag-and-drop task tests your ability to distinguish between traffic-affecting actions (permit/deny) and administrative actions (remark, log, sequence-number), with a common trap being confusion over whether log triggers a log entry for every packet or only matched ones—it logs only matched packets. For a quick memory tip, remember that permit and deny are the "gatekeepers" controlling traffic, while remark, log, and sequence-number are the "support staff" that document, track, or organize the rules.
CCNP ACLs and CoPP Practice Question
This 350-401 practice question tests your understanding of acls and copp. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Correct answer & explanation
✓
permit: Packet is allowed to pass through the ACL
Permit allows the packet; Deny discards the packet; Remark adds a comment; Log generates a log message for matched packets; Sequence-number assigns a line number for editing.
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.

Same concept, more angles
1 more ways this is tested on 350-401
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 each ACL action on the left to its matching result on the right.
easy- ✓ P1.permit: Allows the packet to pass through the ACL
- ✓ P2.deny: Discards the packet and optionally logs it
- ✓ P3.remark: Adds a descriptive comment to the ACL entry
- ✓ P4.log: Generates a log message when the ACL entry is matched
- ✓ P5.established: Matches TCP packets with ACK or RST bit set
Why P1: Permit allows traffic, deny drops traffic, remark adds a comment, log records matches, and established matches TCP with ACK/RST set.
