These questions are derived from the Self Test Software Practice Test for Cisco exam #642-522 – Securing Networks with PIX and ASA.

 

Objective Sequence: Configure a security appliance to provide secure connectivity using site-to-site VPNs
SubObjective Sequence: Differentiate between the types of encryption

 

Multiple Answer, Multiple Choice

 

Which encryption algorithms are supported on a Cisco security appliance ? (Choose three.)

 

 

  1. DES
  2. AES
  3. AES-192
  4. SHA-1
  5. MD5

 

Answer:
A. DES
B. AES
C. AES-192

 

Tutorial:
The encryption algorithms supported on a Cisco security appliance are DES, AES, and AES-192.
The encryption algorithm is a mathematical algorithm used to encrypt or decrypt the data.
The following message encryption algorithms are supported on a Cisco security appliance:

 

 

  • DES – Data Encryption Standard (56 bits)
  • 3DES – Triple Data Encryption Standard (168 bits)
  • AES – Advanced Encryption Standard (128 bits)
  • AES-192 – Advanced Encryption Standard (192 bits)
  • AES-256 – Advanced Encryption Standard (256 bits)

 

The options, SHA-1 and MD5, are incorrect. Secure Hash Algorithm 1 (SHA-1 ) and Message Digest 5 (MD5) are hash algorithms used for data integrity on a Cisco security appliance.
