Cisco 300-745 Dumps Questions Answers

In high-security environments like banking, simply verifying a user's identity is insufficient; the "health" or security state of the device must also be validated.Posture validation, implemented throughCisco Identity Services Engine (ISE), is the specific architectural process used to ensure an endpoint meets the organization's security requirements—such as having an active antivirus, the latest OS patches, or disk encryption enabled—before it is granted access to the internal network.

When an endpoint connects, Cisco ISE triggers a posture check (often via the Cisco Secure Client agent). If the device is found to be non-compliant (e.g., outdated signatures), ISE can move the endpoint into a restrictedquarantineVLAN where it can only access remediation servers to update its software. Only after a successful re-scan shows the device is compliant is the network access policy updated to allow full internal connectivity. This effectively prevents compromised or "dirty" endpoints from spreading threats laterally across the bank's network. WhileMFA(Option A) secures the user's identity andTrustSec(Option B) provides segmentation, only Posture validation addresses the technical compliance of the endpoint hardware and software itself.Data Loss Prevention(Option C) is focused on data transit rather than initial network admission control.

For a financial company, protecting "data at rest" is a critical requirement of the Cisco Security Infrastructure blueprint. While physical security and BIOS-level protections have their place,Data encryption on disk(such as BitLocker, FileVault, or hardware-encrypted drives) is the only solution that fulfills the requirement of rendering the actual data unreadable if the device is lost or stolen.

Disk encryption uses cryptographic algorithms to transform readable data into ciphertext. Without the correct decryption key—which is typically released only after successful user authentication—the data remains a meaningless string of characters even if the hard drive is removed and connected to a different machine. AKensington Lock(Option A) is a physical deterrent to prevent theft but does not protect the data if the lock is cut or the device is stolen. ABIOS password(Option B) can prevent the OS from booting but does not stop an attacker from reading the data directly from the storage media.GPS tracking(Option D) helps in recovery but does not prevent unauthorized data access in the interim. Implementing full-disk encryption aligns with theCisco SAFEprinciple of pervasive data protection and ensures compliance with financial regulations regarding the safeguarding of sensitive client information on mobile endpoints.

In modern DevSecOps, managing third-party dependencies is a major security challenge.Dependabot(often stylized as Depend-a-bot) is the specific GitHub feature designed to automate the identification and updating of vulnerable dependencies. It works by scanning the application's manifest files (like package.json or requirements.txt) and analyzing thesemantic versioningof the included libraries.

When a known vulnerability (CVE) is reported in a specific version of a library used by the application, Dependabot flags the security risk and alerts the development team. Most importantly, it can automatically generate pull requests to upgrade the dependency to the minimum secure version that resolves the vulnerability. This ensures that the application remains secure without requiring manual tracking of every third-party component.

WhileGitHub Actions(Option C) can be used to run security scanners (like SAST tools), it is a general automation framework, not a dedicated dependency analysis tool.Artifact attestations(Option D) are used to prove the provenance and integrity of a build, andSealed boxes(Option B) is not a standard GitHub security feature related to vulnerability scanning. Utilizing Dependabot directly supports the Cisco SDSI objective of "Securing the CI/CD pipeline" by proactively managing the Software Bill of Materials (SBOM) and ensuring that vulnerable components do not reach the production environment.
