The correct answer isC. Check Point Site-to-Site VPN uses IKE/IPsec for VPN tunnel negotiation. The supported IKE versions in normal Check Point VPN terminology areIKEv1andIKEv2. IKEv1 includes Phase 1/Phase 2 behavior such as Main Mode, Aggressive Mode, and Quick Mode, while IKEv2 uses the newer IKE_SA_INIT and IKE_AUTH exchange model. There is no Check Point VPN version called IKEv3 or IKEv4 in this context. Option A is too generic because the question asks which versions are available. Option B and D are wrong because IKEv3 and IKEv4 are not valid Check Point VPN choices. Check Point’s R82 Site-to-Site VPN guide describes IKE as the key-management protocol used to create VPN tunnels and shows IKE configuration through VPN Community encryption settings.
