Just wanted to ask , is one SRX box with high memory (1gb) enough to prepare JNCIE-SEC exam along with 3 SRX base memory models,
I can put 2 base memory models in HA and other two can act as spokes (one of them high memory) ,
Would deploying and testing high memory models with IPS/UTM services in HA would make any difference in learning and testing?
I believe these will be sufficient. I have not tested, but I think you can make a cluster of similar models irrespective of High/Low memory (but can't if there are different modules on one of them) . In this case you can make your High Memory box as a Node0 (Primary) and apply the UTM features as required, but offcourse when Node0 goes down there will be no UTM/IPS and who cares for this in testing only enviroments.
