Which statement is true regarding IPsec VPNs?
A.
There are five phases of IKE negotiation.
B.
There are two phases of IKE negotiation.
C.
IPsec VPN tunnels are not supported on SRX Series devices.
D.
IPsec VPNs require a tunnel PIC in SRX Series devices.
What about there are two phases of IKE negotiation:
The basic purpose of IKE phase 1 is to authenticate the IPSec peers and to set up a secure channel between the peers to enable IKE exchanges.
The purpose of IKE phase 2 is to negotiate IPSec SAs to set up the IPSec tunnel

ANs: B
IKE tunnel establishment happens in two phases:
• Phase 1 establishes a secured channel between gateways for Phase 2 negotiations to occur. The
Diffie-Hellman key exchange algorithm establishes a shared key for encryption.
• Phase 2 establishes the specific VPN connections. SAs are negotiated on behalf of IPsec to determine
the encryption and authentication algorithms to use when sending user data. The SA is identified by a
unique SPI that is also negotiated during Phase 2.
