SSH (Secure Shell) allows encrypted console sessions to access and administer remote servers.
From Quentin Docter - Complete Study Guide:
"Secure Shell (SSH) provides an encrypted console session to manage Linux, UNIX, or network devices securely over TCP port 22." .

These symptoms strongly indicatemalware infectionor a malicious app running in the background. The first action should be torun a malware scanto identify and remove malicious components.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"If a mobile device is overheating and the battery drains rapidly after installing an app, this could point to malware. Begin by scanning the device with a mobile anti-malware application."

This scenario involves a mismatch in device time settings, which can affect synchronization and authentication across the network. Using a Network Time Protocol (NTP) server ensures all networked devices maintain accurate and synchronized clocks.
From Travis Everett - All-in-One Exam Guide:
"NTP servers keep all devices on a network in sync. This prevents time drift, which can cause authentication issues with domain logins, certificates, and applications." .

Comprehensive and Detailed Explanation From Exact Extract:
Credential managers or password vaults (e.g., Windows Credential Manager, KeePass, or LastPass) store passwords securely. The integrity of such tools heavily depends on the strength of the master password protecting the vault. If compromised, all saved credentials could be exposed. Therefore, setting a secure master password is crucial.
A). Login time restrictions are general user account settings, not specific to credential managers.
C). TPM is used more commonly for full disk encryption, not specifically required for password managers.
D). The lock screen protects general access but does not protect stored credentials alone.

The correct answer is A. DLP (Data Loss Prevention), because DLP solutions are specifically designed to detect, monitor, and prevent unauthorized transmission of sensitive data outside an organization.
Information exfiltration occurs when confidential data is improperly transferred, leaked, or stolen, either intentionally or accidentally.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, DLP technologies enforce policies that restrict how data can be shared via email, cloud services, removable media, or network transfers.
DLP systems can block, quarantine, or alert administrators when sensitive data patterns-such as credit card numbers or personal identifiers-are detected leaving the organization.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that DLP focuses on data protection, not user authentication or device management. While IAM controls access to resources and MDM manages mobile devices, neither directly prevents data from being exfiltrated once access is granted.
The Mike Meyers / Mark Soper Lab Manual reinforces that SAML is an authentication framework and does not monitor data movement.
Because the question specifically addresses information exfiltration, the security control designed to prevent it is Data Loss Prevention, making A the correct answer.
