HP HPE7-A08 Practice Test 5

Question 40

Before changing switch configuration, an engineer investigates: An outdoor industrial cabinet requires a ruggedized managed switch with suitable environmental limits. Which FIRST check is most useful for isolating the cause?

Calculate per-port power demand and the total power budget from model datasheets
Check temperature rating, power input, mounting and certified optics
Check model datasheets, transceiver compatibility and stacking feature tables
Cross-check the support matrix, software version and any licensing prerequisites

Explanation

Correct Answer

Check temperature rating, power input, mounting and certified optics. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that industrial environmental certification is a separate selection criterion from VLAN features.

Incorrect Answers

This diagnostic choice fits a different situation: A site wants 48 copper access ports but has a plan for substantial future access growth. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to check temperature rating, power input, mounting and certified optics.

This diagnostic choice fits a different situation: A campus needs resilient access aggregation and growth in uplink bandwidth over several closets. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to check temperature rating, power input, mounting and certified optics.

This diagnostic choice fits a different situation: A proposed switch must support particular advanced routing and security features. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to check temperature rating, power input, mounting and certified optics.

Question 41

An implementation change is planned for: An outdoor industrial cabinet requires a ruggedized managed switch with suitable environmental limits. Which preventive control BEST reduces unnecessary outage and security risk?

Record minimum capacity and future expansion headroom before the purchase
Document independent ISL and keepalive paths with failover tests
Reserve spare ports and quantify peak traffic before ordering
Record the site environment envelope and validated industrial bill of materials

Explanation

Correct Answer

Record the site environment envelope and validated industrial bill of materials. This safeguard is appropriate before the change to evaluate a 4100i industrial switching option for temperature, power and physical mounting constraints; it reduces exposure to the mistake of using a standard indoor switch without verifying the ambient temperature range.

Incorrect Answers

This prevention choice fits a different situation: A small branch needs a fixed access switch for basic VLAN segmentation and modest port counts. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to record the site environment envelope and validated industrial bill of materials.

This prevention choice fits a different situation: Two aggregation switches must provide resilient links without presenting a single physical chassis. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to record the site environment envelope and validated industrial bill of materials.

This prevention choice fits a different situation: A compact data aggregation tier needs high-speed server connections and routed core uplinks. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to record the site environment envelope and validated industrial bill of materials.

Question 42

A first repair attempt for this situation failed: An outdoor industrial cabinet requires a ruggedized managed switch with suitable environmental limits. The review found the mistaken approach of using a standard indoor switch without verifying the ambient temperature range. Which targeted recovery action BEST restores the intended design?

Replace the insufficient power-supply or switch selection and retest the endpoint load
Replace unsupported module combinations and recalculate power and slot allocations
Substitute a ruggedized supported model and retest power and enclosure fit
Swap unsupported hardware or revise the design with a documented equivalent feature path

Explanation

Correct Answer

Substitute a ruggedized supported model and retest power and enclosure fit. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the selected unit is approved for the cabinet environment and interface design.

Question 43

An HPE Aruba Networking engineer faces this wired-network scenario: A site wants 48 copper access ports but has a plan for substantial future access growth. Which implementation action BEST addresses the requirement?

Question 45

An HPE Aruba Networking design review examines: A site wants 48 copper access ports but has a plan for substantial future access growth. Which technical principle BEST explains the required approach?

Modular and fixed switch designs have different capacity and resiliency tradeoffs
Industrial environmental certification is a separate selection criterion from VLAN features
Switch families should be selected against actual interfaces and supported software capabilities
Capacity planning includes PoE and uplinks, not just the number of RJ45 jacks

Explanation

Correct Answer

Question 46

A risk review for the following wired-network case asks what should be avoided: A site wants 48 copper access ports but has a plan for substantial future access growth. Which assumption creates the GREATEST implementation risk?

Assuming every compact switch family supports the same VSF stack size
Assuming any 48-port SKU automatically meets high-power PoE demand
Sizing a modular chassis by port count without examining power or line-card limits
Using a standard indoor switch without verifying the ambient temperature range

Explanation

Correct Answer

Assuming any 48-port SKU automatically meets high-power PoE demand. That shortcut fails because capacity planning includes PoE and uplinks, not just the number of RJ45 jacks. Instead, the appropriate approach is to size the access platform for current ports, PoE demand, uplinks and expansion strategy.
