• A network technician at a teaching hospital receives the campus network design package before starting the wireless rollout in the new outpatient annex. The document lists building names, an overall three-tier topology, and target SSID coverage goals, but no port-by-port switch configuration, IP subnet table, or specific AP model list. Which type of design document is the technician most likely reading?
• The high-level design for a new ward building states that "each wiring closet must have redundant uplinks to the campus aggregation layer to avoid a single point of failure." When reviewing the site's low-level design, which detail should the technician expect to find that fulfills this HLD requirement?
• Before AP installation, the technician reviews a predictive coverage-plan heat map for the imaging wing. The map shows adequate projected signal everywhere except a dip directly outside the MRI suite door. What should the technician conclude from this output?
• The RF plan for a densely populated emergency department specifies 20 MHz channel width on the 5 GHz band instead of 40 MHz, even though 40 MHz would offer higher per-client throughput. What is the most likely reason the designer chose this?
• Reviewing a low-level design diagram for a new ward, the technician sees several switches connecting end-user ports and IP phones directly, uplinking to a pair of larger switches that in turn connect to the campus core. What role do the pair of larger switches perform in this design?
• The low-level design's VLAN table assigns infusion pumps and patient monitors in a ward to a dedicated VLAN, separate from the staff-data VLAN and the guest VLAN. What is the primary design intent behind this separation?
• A low-level design shows two aggregation switches configured as a VSX pair, with access switches in each ward dual-homed to both members. What does this design detail indicate about the intended failure behavior?
• The wireless design document for a high-density outpatient waiting area notes a "5 GHz-preferred" band-steering setting alongside a high AP count. What is the most likely reason the designer emphasizes 5 GHz here?
• In the outpatient annex, the coverage plan specifies APs spaced further apart with lower transmit power for hallway coverage than the same designer used for the crowded annex waiting room. Why would a designer size these two areas differently?
• The low-level design's IP addressing table assigns a separate /24 subnet to each ward floor rather than one large subnet for the whole building. What implication does this design decision have for implementation that the technician should recognize?
• One document in the design package is a predictive RF model generated in planning software before any hardware was installed; another is a post-installation walk-through report with measured signal readings from a handheld device. What distinguishes the second document from the first?
• The RF design calls for small, overlapping AP cells with reduced transmit power throughout the busy emergency department, but large cells with higher transmit power along the outdoor path connecting to the outpatient annex. What principle explains this difference in cell sizing?
• A low-level design's trunk port table lists the ward access switch uplink as carrying only the staff-data VLAN and the management VLAN, deliberately excluding the biomedical-device VLAN. What does this detail imply for a nurse-call system connected to that ward's access switch?
• A hospital's new orthopedics ward is scheduled to receive 40 Aruba access points next week, and the deployment technician wants each AP to pull an address and phone home to Aruba Central the moment it is racked and powered, with zero manual IP entry. Which prerequisite absolutely must be confirmed on the ward's network before install day?
• Before onboarding new AOS-CX switches in the hospital's biomedical engineering lab, the technician plans to enroll them with certificate-based device authentication to Aruba Central. Which prerequisite must be verified first for that certificate validation to succeed?
• A junior technician is planning the pre-implementation checklist for a new nurse-call system that will run over PoE on an access switch stack in the cardiac ward. The stack will also feed access points and desk phones on the same ports. What must the technician calculate before hardware arrives to avoid a failed rollout?
• The outpatient annex across the road is connected back to the main hospital campus by a fiber uplink that the low-level design assumes is already terminated and tested. Before the technician schedules the switch install in the annex, what should be confirmed about that uplink?
• A technician is about to onboard a stack of AOS-CX switches into the new radiology wing but realizes the switches will need to reach Aruba Central over the internet to complete zero-touch provisioning. Which of the following is the correct pre-implementation check to make?
• The hospital wants to ship 12 new access switches directly from the vendor to the maternity ward, have local staff rack and cable them with no networking expertise, and have the switches automatically pull their correct configuration once they power on and reach Aruba Central. Which planning activity makes this possible?
• Procurement bought new Aruba access points for the outpatient annex, but the technician cannot add them to the existing Aruba Central account and finish onboarding. What is the most likely planning gap that was missed before ordering hardware?
• The technician needs to replace an aging access switch that feeds nurse-call panels on a cardiac ward, and the replacement will require roughly 20 minutes of downtime on that switch. What is the correct change-control step to plan before doing the work?
• As part of planning a firmware upgrade on the access switches serving the imaging suites, the technician is asked to include a rollback plan in the change request. What should that rollback plan specifically describe?
• A technician is preparing to pre-stage 15 new access points for the pediatrics wing inside Aruba Central before they ship from the warehouse. Which piece of information about each access point is essential to gather first so the pre-staged record actually matches the physical device on arrival?
• The annex rollout will use new Wi-Fi 6 access points capable of exceeding 1 Gbps per radio, but the existing wiring closet only has older Category 5e cabling run to each AP location. What planning gap does this raise before the access points arrive?
• A technician is preparing wireless SSID profiles in Aruba Central for the new outpatient annex days before the switches and access points even arrive on site. What kind of implementation-preparation task is this?
• Before cutting over the new oncology wing's access switches, the technician assembles an information-gathering checklist covering VLAN IDs, IP addressing, uplink port assignments, and the maintenance window. Why is completing this checklist before install day important?
