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.

By default, traffic is allowed to flow among interfaces that are members of the same zone.

What is an advantage of HIPS that is not provided by IDS? HIPS protects critical system resources and monitors operating system processes. HIPS deploys sensors at network entry points and protects critical network segments. HIPS monitors network processes and protects critical files. HIPS provides quick analysis of events through detailed logging

HIPS protects critical system resources and monitors operating system processes.

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.

It combines the functionalities of antimalware applications with firewall protection.

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.

It is assigned an IP address.

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.

It records the source address in the address table of the switch.

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.

NTP servers at stratum 1 are directly connected to an authoritative time source., NTP servers ensure an accurate time stamp on logging and debugging information.

In the data gathering process, which type of device will listen for traffic, but only gather traffic statistics? NetFlow collector NMS SNMP agent syslog server

NetFlow collector

Which statement describes a difference between RADIUS and TACACS+? RADIUS separates authentication and authorization whereas TACACS+ combines them as one process. RADIUS is supported by the Cisco Secure ACS software whereas TACACS+ is not. RADIUS uses TCP whereas TACACS+ uses UDP. RADIUS encrypts only the password whereas TACACS+ encrypts all communication.

RADIUS encrypts only the password whereas TACACS+ encrypts all communication.

What type of route is created when a network administrator manually configures a route that has an active exit interface? directly connected static local dynamic

Static

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.

The AP periodically sends beacon frames containing the SSID.

What are two disadvantages of using an IDS? (Choose two.) The IDS does not stop malicious traffic. The IDS works offline using copies of network traffic. The IDS has no impact on traffic. The IDS analyzes actual forwarded packets. The IDS requires other devices to respond to attacks.

The IDS does not stop malicious traffic, The IDS requires other devices to respond to attacks.

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.

The client listens for traffic on the channel.

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.

VPNs use virtual connections to create a private network through a public network.
