Cisco Certified Network Professional Security Practice Exam 2025: Latest Questions

A security engineer must ensure all Cisco Firepower Threat Defense (FTD) devices in an organization use the same access control policy and intrusion settings, and changes must be tracked and audited. Which approach best meets this requirement?

A team is implementing a Zero Trust approach. They want to reduce lateral movement by limiting which internal hosts can communicate, based on identity and device context, not only IP subnets. Which capability aligns best with this goal?

An organization wants to prevent data exfiltration to newly registered, high-risk domains and to malicious file-sharing sites. They also want to apply the same controls to roaming users off the corporate network. Which solution best fits?

A company uses 802.1X on wired access ports. They must ensure that devices failing authentication are placed into a restricted network segment for remediation rather than being fully denied. Which 802.1X feature supports this requirement?

After enabling SSL decryption on a secure web gateway, several applications fail due to certificate pinning. Security still requires visibility into destinations and threat blocking without breaking those applications. What is the best next step?

A SOC analyst sees repeated connection attempts from an internal host to many destinations on TCP/445 and TCP/3389. The pattern appears consistent with worm-like lateral movement. Which control is most effective to contain this behavior quickly while maintaining business continuity?

A network uses ISE for guest access. Guests authenticate through a web portal, must accept an acceptable use policy, and should be placed into a guest VLAN with internet-only access. What ISE concept is primarily responsible for returning the user’s network access permissions to the network device after authentication?

An engineer is designing segmentation in a campus using Cisco TrustSec. They want to enforce policy based on group membership across routed boundaries without relying on per-subnet ACLs. Which component carries the group information through the network for enforcement?

A company is using a SIEM to correlate firewall, endpoint, and DNS security events. They want to reduce false positives by ensuring alerts are triggered only when multiple independent indicators align (for example, suspicious DNS plus endpoint process plus blocked C2). What design approach best supports this objective?

An organization is migrating workloads to a public cloud. Security requires consistent Layer 7 inspection and threat prevention for north-south traffic to a set of web applications, while allowing autoscaling of application instances. Which architecture best satisfies these requirements?

A security engineer is designing network segmentation on a campus switching environment. The requirement is to prevent lateral movement between user VLANs while still allowing users to reach shared services (DNS, DHCP, and a print server). Which approach best meets the requirement with the least operational overhead?

A company wants to prevent users from accessing malicious websites. They also want visibility into which internal users are requesting blocked domains. Which solution best provides this capability using DNS as a control point?

An engineer is deploying remote access VPN. The security requirement is to provide per-user access control to internal resources after authentication, rather than granting broad access to the entire network. Which feature best addresses this requirement?

After enabling 802.1X on access ports, an organization finds that certain IoT devices cannot authenticate because they do not support 802.1X. The security team still needs to control access and place these devices into an appropriate restricted VLAN. Which configuration approach best meets the requirement?

A SOC analyst wants to reduce false positives from intrusion alerts by correlating network events with endpoint telemetry (process, file, and user context). Which Cisco architecture best supports this type of cross-domain correlation?

A company uses cloud-hosted SaaS applications and wants to enforce access policies based on user identity, device posture, and risk (for example, blocking access from unmanaged devices). Which solution best fits this requirement?

An endpoint detection solution flags a suspicious executable, but the security team wants to prevent it from running across all endpoints and also retrospectively identify where it has already executed. Which capability best supports both prevention and retrospective investigation?

A firewall is configured with a rule to allow HTTPS from a DMZ web server to an internal database API on TCP/443. Traffic is still being denied. Logs show the deny is happening after the allow rule is matched due to a deeper inspection result. Which feature is the most likely cause of the deny?

An organization is adopting a zero-trust approach for internal access. The requirement is to grant access to specific applications based on continuous verification (user, device posture, and context) without placing the endpoint directly on the internal network. Which architecture best meets this requirement?

A company wants to implement a formal process to evaluate and treat security risks. They need a method to prioritize remediation based on business impact and likelihood. Which approach best aligns with industry security governance practices?

A security team wants to reduce lateral movement between user subnets while minimizing operational overhead. They want access decisions to be based on user identity and device posture rather than static IP/subnet rules. Which design best meets this goal?

Remote users authenticate to the network through a VPN concentrator that uses RADIUS for AAA. Users authenticate successfully, but no role-based access restrictions are applied (everyone receives the same access). Which RADIUS attribute is most commonly used to return group/role information to downstream policy devices such as Cisco ISE or a firewall to drive authorization?

A company uses Secure Web Gateway controls for SaaS access. They want to prevent data exfiltration to personal cloud storage while allowing uploads to approved corporate instances. Which approach best accomplishes this with the least disruption?

After enabling 802.1X for wired access, some endpoints fail authentication and are placed into a restricted VLAN. Packet captures show the endpoint never responds to EAP requests; however, the switch sends EAPOL-Start and EAP-Request frames repeatedly. Which issue is the most likely root cause?

An organization wants to correlate endpoint detections with network telemetry to automatically contain infected hosts. The design requirement is to trigger a network quarantine when the endpoint detection system flags malware, without manually changing switchport VLANs. Which integration/design best meets this requirement?
