Free 300-740 sample questions

1. An architect is replacing a hub-and-spoke design where every branch backhauls SaaS traffic to a data-centre firewall stack. Users complain about latency to Microsoft 365. Which architectural shift best addresses this while preserving policy enforcement?

   • A. Adopt a security service edge model so branches egress locally to a cloud-delivered enforcement point
   • B. Increase the data-centre firewall throughput licence and keep backhauling all traffic
   • C. Deploy a second data centre and split branches evenly between the two backhaul paths
   • D. Disable inspection for Microsoft 365 traffic at the data-centre firewall to reduce delay
   Show answer

   Correct: A. SSE moves inspection into cloud points of presence near the user, removing the hairpin while keeping a single policy. Buying more firewall throughput does not shorten the geographic path, which is the real cause of latency. A second data centre only halves the problem and doubles cost. Disabling inspection restores speed by abandoning the security requirement, which is not an architectural answer.

2. During a zero trust design workshop a stakeholder argues that once a device is on the corporate LAN it should be trusted implicitly. Which zero trust tenet contradicts this position?

   • A. Trust is never granted by network location and must be verified per request
   • B. Encryption must be applied to all traffic regardless of its destination
   • C. Logging must be retained for a minimum period defined by regulation
   • D. Redundant links must exist between every branch and the cloud edge
   Show answer

   Correct: A. Zero trust explicitly rejects the perimeter assumption: being inside the LAN grants nothing, and identity, device posture and context are evaluated for every access request. Universal encryption is a supporting control but does not address the location-trust argument. Log retention is a compliance requirement. Link redundancy is an availability design choice, so none of those rebut the stakeholder.

3. An organisation wants a phased zero trust adoption and asks which capability to deploy first to gain the widest immediate risk reduction across a mixed remote and on-premises workforce.

   • A. Strong multi-factor authentication with device trust on all workforce applications
   • B. Full microsegmentation of every east-west flow in the data centre
   • C. A complete rewrite of legacy applications to support modern token-based auth
   • D. Deployment of remote browser isolation for every outbound web session
   Show answer

   Correct: A. Identity is the first control plane in zero trust and MFA with device trust blocks the credential-theft path behind most intrusions, delivering broad protection quickly. Full microsegmentation is valuable but slow and disruptive to sequence first. Rewriting legacy applications is a multi-year programme. Universal browser isolation is costly and narrow compared with fixing authentication everywhere.

4. A design review must map the zero trust pillars to concrete Cisco capabilities. Which two pairings are accurate? (Choose TWO)

   • A. Workforce trust is addressed by Duo multi-factor authentication and device health checks
   • B. Workload trust is addressed by Secure Workload policy for east-west segmentation
   • C. Workplace trust is addressed by increasing the DNS record time to live values
   • D. Workload trust is addressed by rotating the corporate wireless pre-shared key
   • E. Workforce trust is addressed by extending the DHCP lease duration on user VLANs
   Show answer

   Correct: A and B. Cisco frames zero trust as workforce, workload and workplace: Duo secures user and device access, and Secure Workload discovers application dependencies and enforces segmentation between workloads. DNS TTL values affect caching behaviour, not trust. A wireless pre-shared key is a shared secret unrelated to workload policy. DHCP lease timers are address-management settings with no bearing on workforce trust.

5. A customer must keep certain regulated traffic inspected inside their own country while allowing general internet browsing to use the nearest global point of presence. Which design consideration governs this?

   • A. Data residency and point-of-presence selection within the cloud security service
   • B. The maximum transmission unit configured on the branch WAN interface
   • C. The spanning-tree root bridge priority chosen for the branch access switch
   • D. The administrative distance assigned to the default route at the branch
   Show answer

   Correct: A. Regulated inspection in a specific jurisdiction is solved by pinning traffic to in-country points of presence and confirming where logs are stored, which is a data-residency design decision. MTU affects fragmentation and performance, not jurisdiction. Spanning-tree priority is a Layer 2 topology setting. Administrative distance influences route selection locally but does not determine which country inspects the traffic.
