A network technician is configuring SNMPv3 and has set a security level of SNMPv3 authPriv. What is a feature of using this level?
- authenticates a packet by using the SHA algorithm only
- authenticates a packet by a string match of the username or community string
- authenticates a packet by using either the HMAC with MD5 method or the SHA method
- authenticates a packet by using either the HMAC MD5 or HMAC SHA algorithms and a username
Explanation: The SNMPv3 authPriv security level provides the highest level of protection by combining authentication and encryption. It uses the User-based Security Model (USM), which authenticates packets by using a username in conjunction with either the HMAC-MD5 or HMAC-SHA algorithms. Additionally, the authPriv level adds confidentiality by encrypting the data using algorithms like DES, 3DES, or AES.
