What is the primary drawback to using advanced encryption standard (AES) algorithm with a 256 bit key to share sensitive data?


A. Due to the key size, the time it will take to encrypt and decrypt the message hinders efficient communication.
B. To get messaging programs to function with this algorithm requires complex configurations.
C. It has been proven to be a weak cipher; therefore, should not be trusted to protect sensitive data.
D. It is a symmetric key algorithm, meaning each recipient must receive the key through a different channel than the message.

An attacker sniffs encrypted traffic from the network and is subsequently able to decrypt it. The attacker can now use which cryptanalytic technique to attempt to discover the encryption key?


A. Birthday attack
B. Plaintext attack
C. Meet in the middle attack
D. Chosen ciphertext attack

The fundamental difference between symmetric and asymmetric key cryptographic systems is that symmetric key cryptography uses which of the following?


A. Multiple keys for non-repudiation of bulk data
B. Different keys on both ends of the transport medium
C. Bulk encryption for data transmission over fiber
D. The same key on each end of the transmission medium

Advanced encryption standard is an algorithm used for which of the following?


A. Data integrity
B. Key discovery
C. Bulk data encryption
D. Key recovery

Which of the following is optimized for confidential communications, such as bidirectional voice and video?


A. RC4
B. RC5
C. MD4
D. MD5

What is a successful method for protecting a router from potential smurf attacks?


A. Placing the router in broadcast mode
B. Enabling port forwarding on the router
C. Installing the router outside of the network's firewall
D. Disabling the router from accepting broadcast ping messages

Fingerprinting VPN firewalls is possible with which of the following tools?

What is the main disadvantage of the scripting languages as opposed to compiled programming languages?


A. Scripting languages are hard to learn.
B. Scripting languages are not object-oriented.
C. Scripting languages cannot be used to create graphical user interfaces.
D. Scripting languages are slower because they require an interpreter to run the code.

The use of technologies like IPSec can help guarantee the following: authenticity, integrity, confidentiality and


A. non-repudiation.
B. operability.
C. security.
D. usability.
