Question 8

Which of the following encryption algorithms is considered to be the most secure?
A) MD5
B) DES
C) RSA
D) 3DES

Accepted Answer

RSA is considered the most secure encryption algorithm as it uses a public key for encryption and a private key for decryption. DES and 3DES are considered outdated and vulnerable to brute force attacks. MD5 is a hashing algorithm used for message authentication and not encryption.

Question 9

Which of the following cipher command-line parameters copies encryption key and certificate data to a file that is encrypted for use by the cipher user?
A) /?
B) /k
C) /e
D) /x

Accepted Answer

The /x parameter is used with the cipher command to export the encryption key and certificate data into a file that is encrypted and can be used by the cipher user. This allows for the secure transfer or backup of encryption keys.

Question 10

_____ is an authenticating server for EAP.
A) IAS
B) IIS
C) ISA
D) RADIUS

Accepted Answer

RADIUS (Remote Authentication Dial-In User Service) is an authenticating server that is commonly used with EAP (Extensible Authentication Protocol) to provide secure access to a network for remote users. IAS (Internet Authentication Service) is a legacy Microsoft authentication protocol that is now replaced by NPS (Network Policy Server), and is not commonly used with EAP. IIS (Internet Information Services) is a web server that does not provide authentication services. ISA (Internet Security and Acceleration) is a firewall and proxy server that can provide some authentication services, but is not commonly used with EAP.

Question 11

What encryption method does Red Hat Linux use by default?
A) RSA
B) DES
C) DES3
D) PAM

Accepted Answer

The answer of What encryption method does Red Hat Linux...

Question 12

_____ is the use of a secret code or other means to disguise data that is stored on a computer or transported across a network.
A) Encryption
B) Authentication
C) Hashing
D) Ciphering

Accepted Answer

Encryption is the process of using an algorithm to convert plain text into ciphertext, which is incomprehensible without the key to decrypt it. This is commonly used to protect sensitive information stored on a computer or transmitted over a network from unauthorized access. Authentication is the process of verifying the identity of a user or system, while hashing is a one-way function that converts input data into a fixed-sized value that cannot be reversed. Ciphering is a less commonly used term for encryption.

Question 13

What command can be used from the command prompt window to configure EFS?
A) hash
B) efsconfig
C) msconfig
D) cipher

Accepted Answer

The cipher command is used to configure the Encrypting File System (EFS), which provides encryption for files and folders on NTFS volumes.

Question 14

Which of the following operating systems recognizes the original NTLM logon authentication?
A) Windows 3.11
B) Windows 95
C) Windows Server 2003
D) Both a and b
E) a, b, and c

Accepted Answer

NTLM (NT LAN Manager) is a suite of Microsoft security protocols intended to provide authentication, integrity, and confidentiality to users. Windows 3.11, Windows 95, and Windows Server 2003 all recognize NTLM logon authentication. NTLM has been used since the earliest versions of Windows NT, and it continued to be supported in later versions, including Windows 95 and Windows Server 2003, for backward compatibility and interoperability purposes.

Question 15

What is the RSA key size used by MPPE when it is configured for strongest encryption?
A) 40 bits
B) 54 bits
C) 128 bits
D) 254 bits

Accepted Answer

MPPE (Microsoft Point-to-Point Encryption) uses RSA key size of 128 bits for strongest encryption. Option A and B are weak encryption key sizes, and option D is not a valid RSA key size.

Question 16

Which of the following encryption techniques is employed in UNIX/Linux systems to enable encryption in file systems, using DES, 3DES, and other encryption techniques?
A) RSA
B) PAM
C) CFS
D) AES

Accepted Answer

CFS (Cryptographic File System) is the encryption technique employed in UNIX/Linux systems to enable encryption in file systems, using DES, 3DES, and other encryption techniques. RSA is a public-key encryption algorithm, PAM provides authentication for UNIX/Linux systems, and AES is an encryption standard widely used for data encryption.

Question 17

When following the ISO _____ format, a digital certificate includes a basic set of encrypted information.
A) X10
B) X.502
C) X.509
D) X 802.3

Accepted Answer

The ISO format for digital certificates is X.509. This format includes a basic set of encrypted information such as the certificate holder's name, public key, certificate issuer's name, and expiration date.

Question 18

Which version of hashing algorithm uses a mathematical formula to reduce a message to 160 bits and then hashes a digital signature to go with the message?
A) MD2
B) MD4
C) MD5
D) SHA-1

Accepted Answer

The hashing algorithm that uses a mathematical formula to reduce a message to 160 bits and hashes a digital signature along with the message is SHA-1. It is still considered secure, although there are newer versions of SHA available. MD2, MD4, and MD5 are all older hashing algorithms that are now considered less secure and have had successful attacks against them.

Question 19

_____ authentication works by giving each frame or packet an identification or sequence number. This ensures the accuracy of ongoing communications and the authenticity of the communications source.
A) Network
B) Session
C) System
D) Frame

Accepted Answer

Session authentication works by assigning a unique identification or sequence number to each frame or packet, which helps in verifying the accuracy of ongoing communications and confirming the authenticity of the source. This method is crucial for maintaining secure and reliable communication sessions over networks.

Question 20

What encryption method is often used to create a digital signature?
A) Secret key
B) Hashing
C) DES
D) CFS

Accepted Answer

Hashing is commonly used to create a digital signature. This involves generating a unique hash value for the data being signed, and then using the sender's private key to encrypt the hash value. The recipient can then use the sender's public key to verify the digital signature by decrypting the hash value and comparing it to a recalculated hash of the original data.
