Exam : Cisco 642-532
Title : Securing Networks Using Intrusion Prevention Systems Exam (IPS)


1. In which three ways does a Cisco network sensor protect network devices from attacks? (Choose three.)
A. It uses a blend of intrusion detection technologies to detect malicious network activity.
B. It can generate an alert when it detects traffic that matches a set of rules that pertain to typical intrusion activity.
C. It permits or denies traffic into the protected network that is based on access lists that you create on the sensor.
D. It can take a variety of actions when it detects traffic that matches a set of rules that pertain to typical intrusion activity.
E. It uses behavior-based technology that focuses on the behavior of applications to protect network devices from known attacks and from new attacks for which there is no known signature.
Answer: ABD

2. Which two statements are true about Cisco IPS signatures? (Choose two.)
A. A signature is a set of rules that pertain to typical intrusion activity.
B. When network traffic matches a signature, the signature must generate an alert, but it can also initiate a response action.
C. Some signatures can be triggered by the contents of a single packet.
D. Signatures trigger alerts only when they match a specific pattern of traffic.
E. You can disable signatures and later re-enable them; however, this process requires the sensing engines to rebuild their configuration, which takes time and could delay the processing of traffic.
F. You can enable and modify built-in signatures, but you cannot disable them.
Answer: AC

3. What are three differences between inline and promiscuous sensor functionality? (Choose three.)
A. A sensor that is operating in inline mode can drop the packet that triggers a signature before it reaches its target, but a sensor that is operating in promiscuous mode cannot.
B. A sensor that is operating in inline mode supports more signatures than a sensor that is operating in promiscuous mode.
C. Deny actions are available only to inline sensors, but blocking actions are available only to promiscuous mode sensors.
D. A sensor that is operating in promiscuous mode can perform TCP resets, but a sensor that is operating in inline mode cannot.
E. Inline operation provides more protection from Internet worms than promiscuous mode does.
F. Inline operation provides more protection from atomic attacks than promiscuous mode does.
Answer: AEF

4. Which two are necessary to take into consideration when preparing to tune your sensor? (Choose two.)
A. the security policy
B. the network topology
C. which outside addresses are statically assigned to the servers and which are DHCP addresses
D. the IP addresses of your inside gateway and outside gateway
E. which traffic the sensor denies by default
F. the current configuration for each virtual sensor
Answer: AB

5. How does a Cisco network sensor detect malicious network activity?
A. by using a blend of intrusion detection technologies
B. by performing in-depth analysis of the protocols that are specified in the packets that are traversing the network
C. by comparing network activity to an established profile of normal network activity
D. by using behavior-based technology that focuses on the behavior of applications
