I'm a bit confused by this one. The question specifically asks about agentless implementations, but some of the answer choices mention agent-based stuff. I'll need to really read through the options carefully to make sure I understand how scan caching works in an agentless environment.
I remember learning about scan caching in the context of the Deep Security Virtual Appliance. I think it has to do with reusing malware scan results across VMs to avoid redundant scans. That would make sense for an agentless setup where the scans are handled centrally.
Okay, let's think this through. Scan caching is probably used to improve performance in an agentless setup, since there's no agent on the host to handle the scans. The question mentions it's used in agentless implementations, so that narrows it down. I'll focus on the answer choices that talk about performance and resource management.
I'm pretty sure this has to do with how Deep Security manages malware scans in an agentless environment, but I'm not totally clear on the details. I'll need to review the material on scan caching to make sure I understand it.
The key here is understanding the role of the media manager. It's used for RMAN backups, including writing to tape, and it's required for proxy copies, but not for image copies. I'll go with B and C.
D) Scan caching enhances the performance of the Deep Security Virtual Appliance in that files scanned for malware on a virtual machine that appear on other virtual machines may not need to be scanned again.
Hmm, I'm a bit confused. Isn't the whole point of agentless to, you know, not have an agent? So how does scan caching fit in? Maybe I'm missing something here.
D) Scan caching enhances the performance of the Deep Security Virtual Appliance in that files scanned for malware on a virtual machine that appear on other virtual machines may not need to be scanned again.
Wait, so scan caching is not supported in agentless implementations? That's weird, I would have thought it's a core feature. C doesn't sound right to me.
D) Scan caching enhances the performance of the Deep Security Virtual Appliance in that files scanned for malware on a virtual machine that appear on other virtual machines may not need to be scanned again.
Option D seems the most relevant. The Deep Security Virtual Appliance can definitely benefit from scan caching to avoid rescanning the same files across VMs.
