In PIX versions prior to 7.x， multi-channel protocols were fixedup using the ’fixupprotocol’ command. Inversion 7.0 and higher the ’fixup protocol’commands were replaced by what commands？（） 

A. uses Netflow data for anomaly detections
B. builds baseline profilesof normal operating conditions， enablingrapid identification of unusual activity that indicates an attack
C. accept events inputs from different network devicesvia syslog， SDEE and SNMP
D. dynamic diversion redirects and cleans only traffic destined for targeted devices， allowing unaffectedtraffic toflow freely and ensuring business continuity
E. pushes ACLs to network devices to only block the malicious traffic
F. using topology and configuration awareness， events from different devices are correlatedand attacks mitgitations are performed at the optimal location

A. digital signatures
B. symmetric ciphering
C. hashalgoritms
D. asymmetric ciphering
E. digital certificates

A. uses symmetric crypto for keys distribution
B. uses symmetric crypto for proof of origin
C. uses symmetric crypto for fast encrypted/decryption
D. uses asymmetric crypto for message confidentiality
E. uses symmetric crypto to transmit the asymmetric keys that is thenused to encrypt a session
