Cisco 300-745 Exam Dumps - Actual Questions Answers

According to theCisco Security Incident Responselifecycle and theNIST SP 800-61standards referenced in the SDSI objectives, the very first step in responding to a third-party vulnerability disclosure isIdentification and Validation. Before a team can patch, notify stakeholders, or monitor for exploits, they must perform an asset inventory check to confirm whether the specific vulnerable version of the product is actually running within their environment.

In a complex CI/CD pipeline, multiple tools and versions coexist. Jumping straight to patching (Option D) without validation can lead to unnecessary downtime or "breaking" integrated workflows if the vulnerability doesn't actually apply to the version in use. Similarly, using an IDS (Option A) is a detection/monitoring step that follows the confirmation of risk. Notifying customers (Option B) is a later phase in the incident response process, usually reserved for confirmed breaches or significant service impacts. By confirming the presence and version of the software first, the security team can accurately assess theblast radiusand prioritize remediation efforts based on the actual risk to the university's specific infrastructure. This systematic approach ensures that resources are allocated efficiently and that the security posture is managed based on verified data rather than assumptions.

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.

The spread of malicious content between endpoints is a classic case oflateral movement. To control and restrict communication between individual endpoints—regardless of their physical location or IP address—Cisco TrustSecis the recommended architectural approach. TrustSec moves away from traditional, IP-based Access Control Lists (ACLs), which are difficult to manage and scale, and instead usesScalable Group Tags (SGTs).

With TrustSec, every endpoint is assigned an SGT based on its role or security context (e.g., "Employee," "Contractor," or "HR"). Security policies are then defined in a centralized matrix (the egress policy matrix) that dictates which SGTs can talk to one another. For example, a policy can be set so that endpoints in the "Developer" group cannot communicate directly with endpoints in the "Sales" group, effectively preventing malware from hopping between machines. WhileRADIUS(Option A) is the protocol used for authentication, it does not perform the segmentation itself.Posture(Option C) checks the health of the device, andProfiling(Option D) identifies what the device is, but neither provides the policy-based traffic control of TrustSec. By implementing TrustSec, the company achievesmicro-segmentation, significantly reducing the internal attack surface and containing potential breaches within a single group, which is a core goal of modern secure infrastructure design.
