Q216. _____ is a type of symmetric-key encryption algorithm that transforms a fixed-length block of plaintext (unencrypted text) data into a block of ciphertext (encrypted text) data of the same length.
A. Bit Cipher
B. Hash Cipher
C. Block Cipher
D. Stream Cipher
Answer: C
Explanation: A block cipher is a symmetric key cipher which operates on fixed-length groups of bits, termed blocks, with an unvarying transformation. When encrypting, a block cipher might take a (for example) 128-bit block of plaintext as input, and output a corresponding 128-bit block of ciphertext.
Q217. You are conducting an idlescan manually using HPING2. During the scanning process, you notice that almost every query increments the IPID- regardless of the port being queried. One or two of the queries cause the IPID to increment by more than one value. Which of he following options would be a possible reason?
A. Hping2 can’t be used for idlescanning
B. The Zombie you are using is not truly idle
C. These ports are actually open on the target system
D. A stateful inspection firewall is resetting your queries
Answer: B
Explanation: If the IPID increments more than one value that means that there has been network traffic between the queries so the zombie is not idle.
Q218. How does Traceroute map the route that a packet travels from point A to point B?
A. It uses a TCP Timestamp packet that will elicit a time exceed in transit message.
B. It uses a protocol that will be rejected at the gateways on its way to its destination.
C. It manipulates the value of time to live (TTL) parameter packet to elicit a time exceeded in transit message.
D. It manipulated flags within packets to force gateways into generating error messages.
Answer: C
Explanation: Traceroute works by increasing the "time-to-live" value of each successive batch of packets sent. The first three packets have a time-to-live (TTL) value of one (implying that they make a single hop). The next three packets have a TTL value of 2, and so on. When a packet passes through a host, normally the host decrements the TTL value by one, and forwards the packet to the next host. When a packet with a TTL of one reaches a host, the host discards the packet and sends an ICMP time exceeded (type 11) packet to the sender. The traceroute utility uses these returning packets to produce a list of hosts that the packets have traversed en route to the destination.
Q219. What is the proper response for a FIN scan if the port is closed?
A. SYN
B. ACK
C. FIN
D. PSH
E. RST
Answer: E
Explanation: Closed ports respond to a FIN scan with a RST.
Q220. Which of the following best describes Vulnerability?
A. The loss potential of a threat
B. An action or event that might prejudice security
C. An agent that could take advantage of a weakness
D. A weakness or error that can lead to compromise
Answer: D
Explanation: A vulnerability is a flaw or weakness in system security procedures, design or implementation that could be exercised (accidentally triggered or intentionally exploited) and result in a harm to an IT system or activity.
