Demo Questions
Question 1
Which protocol operates below the network layer?
- A: UDP
- B: ICMP
- C: ARP
- D: DNS
Question 2
Which area is created between screening devices in an egress/ingress path for housing web, mail, or DNS servers?
- A: EMZ
- B: DMZ
- C: harbor
- D: inlet
Question 3
What does protocol normalization do?
- A: compares evaluated packets to normal, daily network-traffic patterns
- B: removes any protocol-induced or protocol-allowable ambiguities
- C: compares a packet to related traffic from the same session, to determine whether the packet is out of sequence
- D: removes application layer data, whether or not it carries protocol-induced anomalies, so that packet headers can be inspected more accurately for signs of abuse
Question 4
On which protocol does Snort focus to decode, process, and alert on suspicious network traffic?
- A: Apple talk
- B: TCP/IP
- C: IPX/SPX
- D: ICMP
Question 5
Which technique can an intruder use to try to evade detection by a Snort sensor?
- A: exceed the maximum number of fragments that a sensor can evaluate
- B: split the malicious payload over several fragments to mask the attack signature
- C: disable a sensor by exceeding the number of packets that it can fragment before forwarding
- D: send more packet fragments than the destination host can reassemble, to disable the host without regard to any intrusion-detection devices that might be on the network
Question 6
An IPS addresses evasion by implementing countermeasures. What is one such countermeasure?
- A: periodically reset statistical buckets to zero for memory utilization, maximization, and performance
- B: send packets to the origination host of a given communication session, to confirm or eliminate spoofing
- C: perform pattern and signature analysis against the entire packet, rather than against individual fragments
- D: automate scans of suspicious source IP addresses
Question 7
Which IPS placement option is the noisiest?
- A: inside the firewall
- B: outside the firewall
- C: inside the DMZ
- D: inside general user segments
Question 8
What is the purpose of using a span or monitor port on a switch?
- A: to aggregate traffic from multiple switch ports
- B: to tap data off network media
- C: to overcome problems that switches have in accurately reproducing desired traffic
- D: to limit the amount of traffic that passes through the switch
Question 9
Which item examines packets for malformation, anomalies, and protocol compliance and gathers and presents packets in one consistent fashion?
- A: Sniffer
- B: preprocessors
- C: detection engine
- D: output and alerting module
Question 10
Which component is one of the four primary components of Snort?
- A: ACL
- B: postprocessor
- C: iptables
- D: output and alerting
