HP HPE7-A08 Practice Test 4

Question 30

After implementing the approved change — Match an HPE aggregation model to port speed, routing, power and buffer requirements — for this scenario: A compact data aggregation tier needs high-speed server connections and routed core uplinks. Which observed result BEST verifies the outcome?

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

Explanation

Correct Answer

Benchmarked throughput and usable ports meet the server and core demand. This is the observable acceptance evidence for the decision to match an HPE aggregation model to port speed, routing, power and buffer requirements. It demonstrates the principle that an access-edge port count alone does not define aggregation suitability.

Incorrect Answers

This verification 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 verification choice is to benchmarked throughput and usable ports meet the server and core demand.

This verification 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 verification choice is to benchmarked throughput and usable ports meet the server and core demand.

This verification choice fits a different situation: A modular campus distribution design requires high-density line cards and redundant control components. It does not resolve the stated failure mode. For this case, the decisive verification choice is to benchmarked throughput and usable ports meet the server and core demand.

Question 31

An HPE Aruba Networking design review examines: A compact data aggregation tier needs high-speed server connections and routed core uplinks. Which technical principle BEST explains the required approach?

Modular and fixed switch designs have different capacity and resiliency tradeoffs
Campus switching choices depend on scale and supported stacking options
Industrial environmental certification is a separate selection criterion from VLAN features
An access-edge port count alone does not define aggregation suitability

Explanation

Correct Answer

An access-edge port count alone does not define aggregation suitability. The case therefore calls for this specifically controlled action: match an HPE aggregation model to port speed, routing, power and buffer requirements. The acceptance evidence is that benchmarked throughput and usable ports meet the server and core demand.

Question 32

A risk review for the following wired-network case asks what should be avoided: A compact data aggregation tier needs high-speed server connections and routed core uplinks. Which assumption creates the GREATEST implementation risk?

Assuming a VSF stack and a VSX pair share identical hardware requirements
Selecting an edge model without checking buffering and uplink throughput
Using a standard indoor switch without verifying the ambient temperature range
Sizing a modular chassis by port count without examining power or line-card limits

Explanation

Correct Answer

Selecting an edge model without checking buffering and uplink throughput. That shortcut fails because an access-edge port count alone does not define aggregation suitability. Instead, the appropriate approach is to match an HPE aggregation model to port speed, routing, power and buffer requirements.

Incorrect Answers

This misconception 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 misconception choice is to selecting an edge model without checking buffering and uplink throughput.

Question 33

Before changing switch configuration, an engineer investigates: A compact data aggregation tier needs high-speed server connections and routed core uplinks. Which FIRST check is most useful for isolating the cause?

Calculate per-port power demand and the total power budget from model datasheets
Inventory port counts, uplink speeds, feature needs and supported model capabilities
Compare slot inventory, power supplies, optics and control-plane redundancy
Compare data rates, oversubscription, forwarding capacity and feature tables

Explanation

Correct Answer

Compare data rates, oversubscription, forwarding capacity and feature tables. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that an access-edge port count alone does not define aggregation suitability.

Incorrect Answers

Question 34

An implementation change is planned for: A compact data aggregation tier needs high-speed server connections and routed core uplinks. Which preventive control BEST reduces unnecessary outage and security risk?

Maintain an explicit model-to-feature compatibility register
Reserve spare ports and quantify peak traffic before ordering
Include spare capacity and a documented supervisor failover acceptance test
Document independent ISL and keepalive paths with failover tests

Explanation

Correct Answer

Reserve spare ports and quantify peak traffic before ordering. This safeguard is appropriate before the change to match an HPE aggregation model to port speed, routing, power and buffer requirements; it reduces exposure to the mistake of selecting an edge model without checking buffering and uplink throughput.

Incorrect Answers

This prevention 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 prevention choice is to reserve spare ports and quantify peak traffic before ordering.

Question 35

A first repair attempt for this situation failed: A compact data aggregation tier needs high-speed server connections and routed core uplinks. The review found the mistaken approach of selecting an edge model without checking buffering and uplink throughput. Which targeted recovery action BEST restores the intended design?

Change to a supported aggregation profile when throughput or interface limits fail acceptance
Substitute a ruggedized supported model and retest power and enclosure fit
Replace the insufficient power-supply or switch selection and retest the endpoint load
Swap unsupported hardware or revise the design with a documented equivalent feature path

Explanation

Correct Answer

Change to a supported aggregation profile when throughput or interface limits fail acceptance. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when benchmarked throughput and usable ports meet the server and core demand.

Incorrect Answers

Question 36

An HPE Aruba Networking engineer faces this wired-network scenario: An outdoor industrial cabinet requires a ruggedized managed switch with suitable environmental limits. Which implementation action BEST addresses the requirement?

Evaluate a 4100i industrial switching option for temperature, power and physical mounting constraints
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

Explanation
