Free Palo Alto Networks Cybersecurity-Apprentice Actual Exam Questions - Question 1 Discussion
departments (e.g., HR, IT, Sales) using network segmentation while ensuring efficient utilization of IP
addresses and controlling traffic flow between segments. Which of the following methods is the most
appropriate to achieve this goal?
D imo, if VLAN support isn’t guaranteed, creating separate subnets alone still segments the network and controls traffic flow. It’s a bit less flexible but avoids relying on switch features that might not exist.
B/D? VLANs in B give better traffic isolation and flexibility. Without VLAN support, D still segments IPs and controls traffic but less efficiently. A flat network or single subnet just won’t scale well here.
It’s B for me. Using VLANs combined with unique subnets per department lets you separate traffic right at Layer 2 and manage IPs cleanly. A flat network (A) just won’t scale or control traffic well, and relying solely on firewalls (C) adds unnecessary complexity. D misses out on the benefits of VLAN isolation, which is important for controlling broadcast domains and improving security within each segment. VLANs are pretty much the standard for this kind of segmentation in medium-sized networks.
B/D? B seems ideal if VLANs and proper routing are in place, letting you segment traffic efficiently and manage IPs well. But if VLAN support or Layer 3 routing isn’t available or too complex, D still achieves segmentation by subnetting alone, which controls IP allocation and isolates departments at Layer 3, even if it’s less flexible. A flat network (A) or a single large subnet (C) just won’t isolate traffic properly or use IPs efficiently. So the choice really hinges on the network equipment capabilities for VLANs and routing.
D imo. While B is solid, if VLANs aren’t supported or are too complex to manage, just using separate subnets for each department still segments the network logically and controls IP allocation well. You can enforce traffic rules with routing policies or ACLs at Layer 3. This setup might be simpler for some environments that don’t have advanced switching gear or need less overhead. It’s not as clean as B with VLAN isolation at Layer 2, but it’s still a practical way to separate traffic and manage IP efficiently without relying on VLAN capabilities.
B. Splitting the network into separate subnets per department and using VLANs is the best combo here. VLANs isolate traffic at Layer 2, and subnetting helps manage IP ranges efficiently. D might seem simpler, but without VLANs, devices from different departments could still share the same physical segment, risking unnecessary traffic exposure. Plus, ACLs on routers or Layer 3 switches can handle inter-VLAN traffic control nicely. So this approach balances segmentation, IP management, and traffic control in a practical way.
This one feels like B again. Splitting by subnets alone (D) without VLANs might isolate IP ranges, but VLANs actually keep traffic separated at the switch level, which is more efficient and secure. A flat network with ACLs (A) or a single large subnet with firewalls (C) would get complicated and less scalable. VLANs combined with subnetting give both segmentation and better control over inter-department traffic.
Makes sense to go with B here. Using both VLANs and subnetting means you get clear separation of traffic at Layer 2 and Layer 3, which is great for managing departments and controlling access. Plus, VLANs help reduce broadcast traffic and keep things efficient. D might seem simpler but without VLANs, devices are still in the same broadcast domain, which can cause unnecessary traffic and security issues. So B covers segmentation and efficient IP use better than the others.
Maybe B is best since using VLANs with subnetting helps separate departments and control traffic efficiently. Flat or single large subnets seem messy for different groups.
