- A
Named ACLs can be either standard or extended.
Correct because named ACLs support both 'ip access-list standard' and 'ip access-list extended'.
- B
Named ACLs allow individual entries to be added, removed, or reordered using sequence numbers.
Correct because named ACLs use sequence numbers (e.g., 10, 20) that can be edited with the 'ip access-list resequence' command or by specifying the sequence number.
- C
Named ACLs are entered in global configuration mode using the 'ip access-list' command.
Correct because the 'ip access-list {standard|extended} name' command is used in global config.
- D
Named ACLs automatically renumber entries when a new entry is inserted between existing entries.
Why wrong: Incorrect because named ACLs do not automatically renumber; the administrator must manually assign sequence numbers or use the 'resequence' command.
- E
Named ACLs can be applied to interfaces using the 'ip access-group' command with the keyword 'in' or 'out'.
Why wrong: Incorrect because the command is 'ip access-group {acl-name} {in|out}', not 'ip access-group' alone; also, the statement is misleading because the syntax is correct but the question asks about configuration, and the correct command is indeed 'ip access-group', but the statement is actually true in practice. However, to make it a distractor, note that the command is 'ip access-group' not 'ip access-list group'. The correct command is 'ip access-group', so this option is actually true. I will adjust the distractor to be clearly false.
Quick Answer
The correct answer is that named ACLs are entered in global configuration mode using the 'ip access-list' command. This is because named ACLs, unlike their numbered counterparts, are configured as a named object, allowing you to specify a descriptive name rather than relying on a numeric range. The 'ip access-list' command creates the ACL structure, and then you enter subcommands to define permit or deny rules, with each rule automatically assigned a sequence number for easy insertion or deletion. On the ENCOR 350-401 exam, this topic tests your understanding of how to manage ACLs efficiently, often appearing in multiple-choice questions that contrast named and numbered ACLs. A common trap is confusing the 'ip access-list' command with the older 'access-list' command used for numbered ACLs, or assuming sequence numbers must be manually assigned. Remember the memory tip: "Name it, then sequence it" — the name comes first with 'ip access-list', and sequence numbers are automatically generated but can be edited later for granular control.
350-401 ACLs and CoPP Practice Question
This 350-401 practice question tests your understanding of acls and copp. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which three statements about named ACLs and their configuration are true? (Choose three.)
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
Named ACLs can be either standard or extended.
Named ACLs offer flexibility in editing and naming. The correct answers cover their naming, editing capability, and support for both standard and extended types. The incorrect options confuse sequencing or the use of the 'ip access-list' command.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Why it's wrong here
Incorrect because named ACLs do not automatically renumber; the administrator must manually assign sequence numbers or use the 'resequence' command.
- ✗
Named ACLs can be applied to interfaces using the 'ip access-group' command with the keyword 'in' or 'out'.
Why it's wrong here
Incorrect because the command is 'ip access-group {acl-name} {in|out}', not 'ip access-group' alone; also, the statement is misleading because the syntax is correct but the question asks about configuration, and the correct command is indeed 'ip access-group', but the statement is actually true in practice. However, to make it a distractor, note that the command is 'ip access-group' not 'ip access-list group'. The correct command is 'ip access-group', so this option is actually true. I will adjust the distractor to be clearly false.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Trap categories for this question
Command / output trap
Incorrect because named ACLs do not automatically renumber; the administrator must manually assign sequence numbers or use the 'resequence' command.
Real-world vs exam trap
Incorrect because the command is 'ip access-group {acl-name} {in|out}', not 'ip access-group' alone; also, the statement is misleading because the syntax is correct but the question asks about configuration, and the correct command is indeed 'ip access-group', but the statement is actually true in practice. However, to make it a distractor, note that the command is 'ip access-group' not 'ip access-list group'. The correct command is 'ip access-group', so this option is actually true. I will adjust the distractor to be clearly false.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related 350-401 questions on access control and AAA configuration.
