QuestionQ52

Network Design

An engineer must secure the payload traversing the DCI. The solution must provide confidentiality and integrity, be an open standard, and encrypt Ethernet frames regardless of the upper-layer protocol in use.

Which technology must be used to meet these requirements?

  • A GRE
  • B OTV
  • C MACsec
  • D IPsec
Explanation

MACsec, standardized as IEEE 802.1AE, provides confidentiality and integrity protection at the Ethernet MAC layer. It protects Ethernet frames transparently to higher-layer protocols, satisfying the requirement to encrypt frames regardless of the protocol they carry.
