HP HPE7-A08 Practice Test 3

Question 20

An implementation change is planned for: A modular campus distribution design requires high-density line cards and redundant control components. Which preventive control BEST reduces unnecessary outage and security risk?

Reserve spare ports and quantify peak traffic before ordering
Include spare capacity and a documented supervisor failover acceptance test
Test a representative VSF topology and document stack roles
Record minimum capacity and future expansion headroom before the purchase

Explanation

Correct Answer

Include spare capacity and a documented supervisor failover acceptance test. This safeguard is appropriate before the change to evaluate the supported 6400 modular switching platform against chassis and supervisory redundancy needs; it reduces exposure to the mistake of sizing a modular chassis by port count without examining power or line-card limits.

Incorrect Answers

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 include spare capacity and a documented supervisor failover acceptance test.

This prevention 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 prevention choice is to include spare capacity and a documented supervisor failover acceptance test.

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 include spare capacity and a documented supervisor failover acceptance test.

Question 21

A first repair attempt for this situation failed: A modular campus distribution design requires high-density line cards and redundant control components. The review found the mistaken approach of sizing a modular chassis by port count without examining power or line-card limits. Which targeted recovery action BEST restores the intended design?

Replace unsupported module combinations and recalculate power and slot allocations
Replace the unsuitable chassis proposal with an access-model bill of materials validated against the requirements
Swap unsupported hardware or revise the design with a documented equivalent feature path
Revise the model and stacking plan to a supported combination before deployment

Explanation

Correct Answer

Replace unsupported module combinations and recalculate power and slot allocations. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the proposed chassis and modules meet slot, port and resilience requirements.

Incorrect Answers

Question 22

An HPE Aruba Networking engineer faces this wired-network scenario: Two aggregation switches must provide resilient links without presenting a single physical chassis. Which implementation action BEST addresses the requirement?

Evaluate the supported 6400 modular switching platform against chassis and supervisory redundancy needs
Select compatible VSX-capable aggregation models and design independent peer plus ISL and keepalive connectivity
Match an HPE aggregation model to port speed, routing, power and buffer requirements
Compare supported HPE Aruba Networking access series and select an appropriately sized 6100-class design if requirements fit

Explanation

Correct Answer

VSX permits coordinated switching while peers remain distinct devices. The targeted implementation is to select compatible VSX-capable aggregation models and design independent peer plus ISL and keepalive connectivity. The deployment succeeds when the resulting peer design has supported models and separate failure paths.

Question 23

After implementing the approved change — Select compatible VSX-capable aggregation models and design independent peer plus ISL and keepalive connectivity — for this scenario: Two aggregation switches must provide resilient links without presenting a single physical chassis. Which observed result BEST verifies the outcome?

The proposed chassis and modules meet slot, port and resilience requirements
The chosen switch supports the required edge ports and VLANs without unneeded core features
The validated design meets stack member, uplink and redundancy targets

Explanation

Correct Answer

The resulting peer design has supported models and separate failure paths. This is the observable acceptance evidence for the decision to select compatible VSX-capable aggregation models and design independent peer plus ISL and keepalive connectivity. It demonstrates the principle that vSX permits coordinated switching while peers remain distinct devices.

Question 24

An HPE Aruba Networking design review examines: Two aggregation switches must provide resilient links without presenting a single physical chassis. Which technical principle BEST explains the required approach?

Capacity planning includes PoE and uplinks, not just the number of RJ45 jacks
VSX permits coordinated switching while peers remain distinct devices
Switch families should be selected against actual interfaces and supported software capabilities
Modular and fixed switch designs have different capacity and resiliency tradeoffs

Explanation

Correct Answer

VSX permits coordinated switching while peers remain distinct devices. The case therefore calls for this specifically controlled action: select compatible VSX-capable aggregation models and design independent peer plus ISL and keepalive connectivity. The acceptance evidence is that the resulting peer design has supported models and separate failure paths.

Incorrect Answers

Question 25

A risk review for the following wired-network case asks what should be avoided: Two aggregation switches must provide resilient links without presenting a single physical chassis. Which assumption creates the GREATEST implementation risk?

Using a standard indoor switch without verifying the ambient temperature range
Assuming any 48-port SKU automatically meets high-power PoE demand
Buying a large aggregation chassis merely because the site uses VLANs
Assuming a VSF stack and a VSX pair share identical hardware requirements

Explanation

Correct Answer

Assuming a VSF stack and a VSX pair share identical hardware requirements. That shortcut fails because vSX permits coordinated switching while peers remain distinct devices. Instead, the appropriate approach is to select compatible VSX-capable aggregation models and design independent peer plus ISL and keepalive connectivity.

Incorrect Answers

This misconception choice fits a different situation: An outdoor industrial cabinet requires a ruggedized managed switch with suitable environmental limits. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to assuming a VSF stack and a VSX pair share identical hardware requirements.

Question 26

Before changing switch configuration, an engineer investigates: Two aggregation switches must provide resilient links without presenting a single physical chassis. Which FIRST check is most useful for isolating the cause?

Check temperature rating, power input, mounting and certified optics
Check each candidate series for VSX support, interfaces and fabric topology
Cross-check the support matrix, software version and any licensing prerequisites
Check model datasheets, transceiver compatibility and stacking feature tables

Explanation

Correct Answer

Check each candidate series for VSX support, interfaces and fabric topology. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that vSX permits coordinated switching while peers remain distinct devices.

Document power and port headroom with expansion thresholds
Record minimum capacity and future expansion headroom before the purchase
Document independent ISL and keepalive paths with failover tests

Explanation

Question 29

An HPE Aruba Networking engineer faces this wired-network scenario: A compact data aggregation tier needs high-speed server connections and routed core uplinks. Which implementation action BEST addresses the requirement?

Size the access platform for current ports, PoE demand, uplinks and expansion strategy
Evaluate a 6300-class access aggregation design with model-supported VSF options and uplink capacity
Select compatible VSX-capable aggregation models and design independent peer plus ISL and keepalive connectivity
Match an HPE aggregation model to port speed, routing, power and buffer requirements

Explanation

Correct Answer
