1. Question
In which configuration would an outbound ACL placement be preferred over an inbound ACL placement?
- when the ACL is applied to an outbound interface to filter packets coming from multiple inbound interfaces before the packets exit the interface
- when a router has more than one ACL
- when an outbound ACL is closer to the source of the traffic flow
- when an interface is filtered by an outbound ACL and the network attached to the interface is the source network being filtered within the ACL
2. Question
Which address is required in the command syntax of a standard ACL?
- source MAC address
- destination MAC address
- source IP address
- destination IP address
3. Question
Which statement describes a difference between the operation of inbound and outbound ACLs?
- In contrast to outbound ALCs, inbound ACLs can be used to filter packets with multiple criteria.
- Inbound ACLs can be used in both routers and switches but outbound ACLs can be used only on routers.
- Inbound ACLs are processed before the packets are routed while outbound ACLs are processed after the routing is completed.
- On a network interface, more than one inbound ACL can be configured but only one outbound ACL can be configured.
4. Question
Which three statements describe ACL processing of packets? (Choose three.)
- An implicit deny any rejects any packet that does not match any ACE.
- A packet can either be rejected or forwarded as directed by the ACE that is matched.
- A packet that has been denied by one ACE can be permitted by a subsequent ACE.
- A packet that does not match the conditions of any ACE will be forwarded by default.
- Each statement is checked only until a match is detected or until the end of the ACE list.
- Each packet is compared to the conditions of every ACE in the ACL before a forwarding decision is made.
5. Question
What single access list statement matches all of the following networks?
192.168.16.0
192.168.17.0

- access-list 10 permit 192.168.0.0 0.0.15.255
6. Question
A network administrator needs to configure a standard ACL so that only the workstation of the administrator with the IP address 192.168.15.23 can access the virtual terminal of the main router. Which two configuration commands can achieve the task? (Choose two.)
- Router1(config)# access-list 10 permit host 192.168.15.23
- Router1(config)# access-list 10 permit 192.168.15.23 0.0.0.0
- Router1(config)# access-list 10 permit 192.168.15.23 0.0.0.255
- Router1(config)# access-list 10 permit 192.168.15.23 255.255.255.0
- Router1(config)# access-list 10 permit 192.168.15.23 255.255.255.255

If a router has two interfaces and is routing both IPv4 and IPv6 traffic, how many ACLs could be created and applied to it?
- 4
- 6
- 8
- 12
- 16
8. Question
Which three statements are generally considered to be best practices in the placement of ACLs? (Choose three.)
- Place standard ACLs close to the source IP address of the traffic.
- Place extended ACLs close to the destination IP address of the traffic.
- Filter unwanted traffic before it travels onto a low-bandwidth link.
- Place extended ACLs close to the source IP address of the traffic.
- Place standard ACLs close to the destination IP address of the traffic.
- For every inbound ACL placed on an interface, there should be a matching outbound ACL.

- on the router that routes the packet referenced in the ACL from the source network
- on any router through which the packet referenced in the ACL travels
- on the router that has the ACL configured
13. Question
What is the quickest way to remove a single ACE from a named ACL?
- Use the no keyword and the sequence number of the ACE to be removed.
- Use the no access-list command to remove the entire ACL, then recreate it without the ACE.
- Copy the ACL into a text editor, remove the ACE, then copy the ACL back into the router.
- Create a new ACL with a different number and apply the new ACL to the router interface.

The administrator attempts to add a new ACE to the ACL that denies packets from host 172.16.0.1 and receives the error message that is shown in the exhibit. What action can the administrator take to block packets from host 172.16.0.1 while still permitting all other traffic from the 172.16.0.0 network?
CCNA2 v6.0 Chapter 7 Exam 005
- Manually add the new deny ACE with a sequence number of 5.

CCNA2 v6.0 Chapter 7 Exam 004
- Only traffic from the 172.16.4.0/24 subnet is blocked, and all other traffic is allowed.
- An extended ACL must be used in this situation.
- The ACL should be applied to the FastEthernet 0/0 interface of R1 inbound to accomplish the requirements.
- All traffic will be blocked, not just traffic from the 172.16.4.0/24 subnet.
- The ACL should be applied outbound on all interfaces of R1.
20. Question
Refer to the exhibit. What will happen to the access list 10 ACEs if the router is rebooted before any other commands are implemented?
CCNA2 v6.0 Chapter 7 Exam 003
- The ACEs of access list 10 will be deleted.
- The ACEs of access list 10 will not be affected.
- The ACEs of access list 10 will be renumbered.
- The ACEs of access list 10 wildcard masks will be converted to subnet masks.
21. Question
What is the effect of configuring an ACL with only ACEs that deny traffic?
- The ACL will permit any traffic that is not specifically denied.
- The ACL will block all traffic.
- The ACL must be applied inbound only.
- The ACL must be applied outbound only.
22. Question
Which type of ACL statements are commonly reordered by the Cisco IOS as the first ACEs?
- host
- range
- permit any
- lowest sequence number
23. Question
A network administrator is configuring an ACL to restrict access to certain servers in the data center. The intent is to apply the ACL to the interface connected to the data center LAN. What happens if the ACL is incorrectly applied to an interface in the inbound direction instead of the outbound direction?
- All traffic is denied.
- All traffic is permitted.
- The ACL does not perform as designed.
- The ACL will analyze traffic after it is routed to the outbound interface.
24. Question
When would a network administrator use the clear access-list counters command?
- when obtaining a baseline
- when buffer memory is low
- when an ACE is deleted from an ACL
- when troubleshooting an ACL and needing to know how many packets matched
