The IDS works offline using copies of network traffic.
The IDS has no impact on traffic.
The IDS analyzes actual forwarded packets.

4. Which statement describes one of the rules that govern interface behavior in the context of implementing a zone-based policy firewall configuration?
An administrator can assign interfaces to zones, regardless of whether the zone has been configured.
An administrator can assign an interface to multiple security zones.
By default, traffic is allowed to flow among interfaces that are members of the same zone.*
By default, traffic is allowed to flow between a zone member interface and any interface that is not a zone member.
5. Which technique is necessary to ensure a private transfer of data using a VPN?
6. What is the function of the distribution layer of the three-layer network design model?
providing direct access to the network
providing secure access to the Internet
aggregating access layer connections*

email virus and spam filtering
8. Which AAA component can be established using token cards?
9. Which statement describes a VPN?
VPNs use open source virtualization software to create the tunnel through the Internet.
VPNs use dedicated physical connections to transfer data between remote users.
VPNs use logical connections to create public networks through the Internet.
VPNs use virtual connections to create a private network through a public network.*
10. What is a host-based intrusion detection system (HIDS)?
It detects and stops potential direct attacks but does not scan for malware.
It is an agentless system that scans files on a host for potential malware.
It identifies potential attacks and sends alerts but does not stop the traffic.
It combines the functionalities of antimalware applications with firewall protection.*
11. Which two devices would commonly be found at the access layer of the hierarchical enterprise LAN design model? (Choose two.)
Layer 3 device
Layer 2 switch*
12. Which two statements are true about NTP servers in an enterprise network? (Choose two.)
There can only be one NTP server on an enterprise network.
NTP servers at stratum 1 are directly connected to an authoritative time source.*
NTP servers control the mean time between failures (MTBF) for key network devices.
NTP servers ensure an accurate time stamp on logging and debugging information.*
All NTP servers synchronize directly to a stratum 1 time source.
13. In the data gathering process, which type of device will listen for traffic, but only gather traffic statistics?
14. Which two protocols are link-state routing protocols? (Choose two.)
15. What type of route is created when a network administrator manually configures a route that has an active exit interface?
16. Which characteristic describes a wireless client operating in active mode?
must be configured for security before attaching to an AP
broadcasts probes that request the SSID
ability to dynamically change channels
must know the SSID to connect to an AP*
17. What are two types of addresses found on network end devices? (Choose two.)
18. What is a characteristic of the WLAN passive discover mode?
The client must know the name of the SSID to begin the discover process.
The client begins the discover process by sending a probe request.
The beaconing feature on the AP is disabled.
The AP periodically sends beacon frames containing the SSID.*
19. What is a characteristic of a routed port that is configured on a Cisco switch?
It supports subinterfaces.
It is associated with a single VLAN.
It runs STP to prevent loops.
It is assigned an IP address.*
20. What action does an Ethernet switch take when it receives a frame with an unknown Layer 2 source address?
It forwards the frame out all interfaces except the interface on which it was received.
It forwards the frame to the default gateway.
It records the source address in the address table of the switch.*
It drops the frame.
21.. Match each device to a category.
22. Which routing protocol is used to exchange routes between internet service providers?
23. What is the first step in the CSMA/CA process when a wireless client is attempting to communicate on the wireless network?
The client sends an RTS message to the AP.
The client sends a test frame onto the channel.
The client listens for traffic on the channel.*
The AP sends a CTS message to the client.
24. What Wi-Fi management frame is regularly broadcast by APs to announce their presence?
