HP IT Infrastructure & Networking 3 — Questions and Answers
Question 1: Which HP storage technology uses Non-Volatile Memory Express (NVMe) over Fabrics to provide low-latency storage access across a network?
- HP 3PAR StoreServ
- HP Nimble Storage dHCI
- HP Primera with NVMe-oF (Correct answer)
- HP StoreEver
Correct answer: HP Primera with NVMe-oF
HP Primera supports NVMe-oF, extending NVMe's low-latency benefits across fiber channel or Ethernet fabrics to shared storage.
Question 2: An administrator needs to aggregate two 10GbE links between an HP server and an HP switch for bandwidth and redundancy. Which protocol should be configured?
- Spanning Tree Protocol (STP)
- Link Aggregation Control Protocol (LACP) (Correct answer)
- Hot Standby Router Protocol (HSRP)
- Rapid Spanning Tree Protocol (RSTP)
Correct answer: Link Aggregation Control Protocol (LACP)
LACP (IEEE 802.3ad) dynamically negotiates link aggregation between devices, combining multiple physical links into a single logical channel.
Question 3: What is the maximum number of nodes supported in an HP Moonshot chassis?
- 15
- 45 (Correct answer)
- 180
- 720
Correct answer: 45
The HP Moonshot 1500 chassis supports up to 45 server cartridges in a 4.3U form factor for dense, low-power workloads.
Question 4: In HP OneView, what is a 'Server Profile Template' used for?
- Defining BIOS settings for individual servers only
- Creating reusable configuration baselines that can be applied to multiple servers (Correct answer)
- Monitoring server health and alerting on failures
- Scheduling automated firmware updates
Correct answer: Creating reusable configuration baselines that can be applied to multiple servers
Server Profile Templates in HP OneView define a standard configuration that can be applied consistently across multiple servers for rapid deployment.
Question 5: Which spanning tree mode on HP Aruba switches provides the fastest convergence time after a topology change?
- STP (802.1D)
- PVST+
- RSTP (802.1w) (Correct answer)
- MST (802.1s)
Correct answer: RSTP (802.1w)
RSTP (Rapid Spanning Tree Protocol) converges significantly faster than legacy STP by using proposal/agreement handshakes instead of timers.
Question 6: HP Nimble Storage uses which predictive analytics technology to forecast and prevent storage issues before they impact performance?
- HP OneView Analytics
- InfoSight (Correct answer)
- HP iLO Analytics
- HP Synergy Composer
Correct answer: InfoSight
HP Nimble InfoSight uses machine learning to analyze telemetry from millions of storage sensors to predict and prevent performance issues proactively.
Question 7: When configuring Quality of Service (QoS) on an HP Aruba switch, which marking method operates at Layer 3 of the OSI model?
- 802.1p CoS
- DSCP (Differentiated Services Code Point) (Correct answer)
- Port-based priority
- MAC address classification
Correct answer: DSCP (Differentiated Services Code Point)
DSCP marks traffic priority in the IP header's ToS field at Layer 3, while 802.1p CoS operates at Layer 2 using VLAN tag bits.
