CompTIA CySA+ CS0-003 (V3) Practice Question

A junior SOC analyst captures the beginning of a TLS 1.2 handshake in Wireshark. The Server Hello advertises the cipher suite TLS_DHE_RSA_WITH_AES_128_GCM_SHA256. The lead analyst explains that the three-letter component DHE designates a mechanism that performs an asymmetric key exchange so the client and server can agree on a premaster secret, after which the negotiated AES cipher protects all remaining traffic-providing perfect forward secrecy for the session. Which technique is represented by DHE in this cipher suite?

  • Advanced Encryption Standard (AES)

  • Elliptic Curve Diffie-Hellman static (ECDH)

  • Diffie-Hellman Ephemeral (DHE)

  • RSA key transport
