Q332. An organization does not have adequate resources to administer its large infrastructure. A security administrator wishes to combine the security controls of some of the network devices in the organization. Which of the following methods would BEST accomplish this goal?
A. Unified Threat Management
B. Virtual Private Network
C. Single sign on
D. Role-based management
Answer: A
Explanation:
When you combine a firewall with other abilities (intrusion prevention, antivirus, content filtering, etc.), what used to be called an all-in-one appliance is now known as a unified threat management (UTM) system. The advantages of combining everything into one include a reduced learning curve (you only have one product to learn), a single vendor to deal with, and—typically—reduced complexity.
Q333. Which of the following BEST describes part of the PKI process?
A. User1 decrypts data with User2’s private key
B. User1 hashes data with User2’s public key
C. User1 hashes data with User2’s private key
D. User1 encrypts data with User2’s public key
Answer: D
Explanation:
In a PKI the sender encrypts the data using the receiver's public key. The receiver decrypts the
data using his own private key.
PKI is a two-key, asymmetric system with four main components: certificate authority (CA),
registration authority (RA), RSA (the encryption algorithm), and digital certificates. Messages are
encrypted with a public key and decrypted with a private key.
A PKI example:
1.
You want to send an encrypted message to Jordan, so you request his public key.
2.
Jordan responds by sending you that key.
3.
You use the public key he sends you to encrypt the message.
4.
You send the message to him.
5.
Jordan uses his private key to decrypt the message.
Q334. Which of the following BEST describes using a smart card and typing in a PIN to gain access to a system?
A. Biometrics
B. PKI
C. Single factor authentication
D. Multifactor authentication
Answer: D
Explanation:
Multifactor authentication requires a user to provide two or more authentication factors for authentication purposes. In this case, a smart card (something they have) is one and a PIN (something they know) is the second.
Q335. A software development company has hired a programmer to develop a plug-in module to an existing proprietary application. After completing the module, the developer needs to test the entire application to ensure that the module did not introduce new vulnerabilities. Which of the following is the developer performing when testing the application?
A. Black box testing
B. White box testing
C. Gray box testing
D. Design review
Answer: C
Explanation:
In this question, we know the tester has some knowledge of the application because the tester developed a plug-in module for it. However, the tester does not have detailed information about the entire application. Therefore, this is a grey-box test. Gray box testing, also called gray box analysis, is a strategy for software debugging in which the tester has limited knowledge of the internal details of the program. A gray box is a device, program or system whose workings are partially understood. Gray box testing can be contrasted with black box testing, a scenario in which the tester has no knowledge or access to the internal workings of a program, or white box testing, a scenario in which the internal particulars are fully known. Gray box testing is commonly used in penetration tests. Gray box testing is considered to be non-intrusive and unbiased because it does not require that the tester have access to the source code. With respect to internal processes, gray box testing treats a program as a black box that must be analyzed from the outside. During a gray box test, the person may know how the system components interact but not have detailed knowledge about internal program functions and operation. A clear distinction exists between the developer and the tester, thereby minimizing the risk of personnel conflicts.

Q336. A company’s legacy server requires administration using Telnet. Which of the following protocols could be used to secure communication by offering encryption at a lower OSI layer? (Select TWO).
A. IPv6
B. SFTP
C. IPSec
D. SSH
E. IPv4
Answer: A,C
Explanation:
Telnet supports IPv6 connections. IPv6 is the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPsec is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec is a compulsory component for IPv6.
IPsec operates at Layer 3 of the OSI model, whereas Telnet operates at Layer 7.
Q337. A program displays:
ERROR: this program has caught an exception and will now terminate.
Which of the following is MOST likely accomplished by the program’s behavior?
A. Operating system’s integrity is maintained
B. Program’s availability is maintained
C. Operating system’s scalability is maintained
D. User’s confidentiality is maintained
Answer: A
Explanation:
The purpose of error handling is to maintain the security and integrity of the system. Integrity is compromised when unauthorized modification occurs.
Q338. A company has proprietary mission critical devices connected to their network which are configured remotely by both employees and approved customers. The administrator wants to monitor device security without changing their baseline configuration. Which of the following should be implemented to secure the devices without risking availability?
A. Host-based firewall
B. IDS
C. IPS
D. Honeypot
Answer: B
Explanation:
Q339. Sara, a security engineer, is testing encryption ciphers for performance. Which of the following ciphers offers strong encryption with the FASTEST speed?
A. 3DES
B. Blowfish
C. Serpent
D. AES256
Answer: B
Explanation:
Blowfish is an encryption system invented by a team led by Bruce Schneier that performs a 64-bit block cipher at very fast speeds. Blowfish is a fast, except when changing keys. It is a symmetric block cipher that can use variable-length keys (from 32 bits to 448 bits).
Q340. A company has purchased an application that integrates into their enterprise user directory for account authentication. Users are still prompted to type in their usernames and passwords. Which of the following types of authentication is being utilized here?
A. Separation of duties
B. Least privilege
C. Same sign-on
D. Single sign-on
Answer: C
Explanation: Same sign-on requires the users to re-enter their credentials but it allows them to use the same credentials that they use to sign on locally.
