Since the logs on the endpoint were deleted, the next best option for the analyst is to examine firewall logs.
Firewall logs can reveal external communication, including outbound traffic to a command-and-control (C2) server. These logs would contain information about the IP addresses, ports, and protocols used, which can help in identifying suspicious connections.
* IPS logs may provide information about network intrusions, but firewall logs are better for tracking communication patterns.
* ACL logs (Access Control List) are useful for tracking access permissions but not for identifying C2 communication.
* Windows security logs would have been ideal if they had not been deleted

A full inventory of all hardware and software is essential for measuring the overall risk to an organization when a new vulnerability is disclosed, because it allows the security analyst to identify which systems are affected by the vulnerability and prioritize the remediation efforts. Without a full inventory, the security analyst may miss some vulnerable systems or waste time and resources on irrelevant ones. Documentation of system classifications, a list of system owners and their departments, and third-party risk assessment documentation are all useful for risk management, but they are not sufficient to measure the impact of a new vulnerability.

A non-disclosure agreement (NDA) restricts employees from sharing proprietary or confidential information when they leave the company. Legal consequences may result from violating an NDA.

A cold site is a backup facility that provides basic power, space, and environmental controls but does not include hardware or preconfigured systems. It is the organization's responsibility to ensure the site has adequate storage, servers, and equipment staged or available for rapid procurement.
If the cold site "does not have enough storage and computers," the cause is a failure in capacity planning (A)
. CompTIA Security+ SY0-701 highlights the need for organizations to determine:
* Required compute capacity
* Storage needs
* Network bandwidth
* Expected recovery workload
* Hardware replacement timelines
Load balancing (B) distributes traffic; it has nothing to do with cold-site readiness. Backups (C) store data, not physical resources. Platform diversity (D) refers to using multiple technologies to reduce systemic risk.
The issue is specifically the lack of resources, which directly reflects inadequate capacity planning.
Therefore, A is the correct answer.
