HP IT Infrastructure & Networking 2 — Questions and Answers
Question 1: Which HP ProLiant server feature allows administrators to remotely manage a server even when the OS is down or the server is powered off?
- HP Smart Array
- HP iLO (Integrated Lights-Out) (Correct answer)
- HP OneView
- HP Service Pack for ProLiant
Correct answer: HP iLO (Integrated Lights-Out)
HP iLO provides out-of-band remote management capabilities independent of the server's OS or power state.
Question 2: In an HP FlexFabric networking environment, what does 'IRF' (Intelligent Resilient Framework) primarily provide?
- Wireless mesh networking
- Virtual chassis stacking for unified management (Correct answer)
- Intrusion detection and prevention
- SD-WAN overlay routing
Correct answer: Virtual chassis stacking for unified management
IRF allows multiple physical HP switches to be virtualized into a single logical device, simplifying management and improving resilience.
Question 3: Which RAID level used in HP Smart Array controllers provides disk striping with dual parity, tolerating up to two simultaneous drive failures?
- RAID 5
- RAID 6 (Correct answer)
- RAID 10
- RAID 50
Correct answer: RAID 6
RAID 6 uses dual distributed parity, allowing the array to survive two concurrent drive failures without data loss.
Question 4: What is the purpose of HP Virtual Connect in a BladeSystem environment?
- Providing GPU acceleration for blade servers
- Abstracting server I/O from the physical network infrastructure (Correct answer)
- Managing power distribution across blade enclosures
- Encrypting data-at-rest on blade storage
Correct answer: Abstracting server I/O from the physical network infrastructure
HP Virtual Connect decouples server I/O from the network, allowing server profiles to be moved without reconfiguring upstream switches.
Question 5: An HP Aruba switch is configured with 802.1X port-based authentication. What happens to traffic from a device that fails authentication by default?
- Traffic is allowed on a guest VLAN
- Traffic is rate-limited to 1 Mbps
- The port is placed in an unauthorized state and traffic is blocked (Correct answer)
- Traffic is redirected to a captive portal
Correct answer: The port is placed in an unauthorized state and traffic is blocked
By default, when 802.1X authentication fails, the switch port enters an unauthorized state and drops all non-EAP traffic.
Question 6: Which technology in HP Synergy composable infrastructure allows compute, storage, and network resources to be dynamically allocated as needed?
- HP OneView templates
- Software-defined resource pools (Correct answer)
- HP Service Pack for ProLiant
- HP iLO Federation
Correct answer: Software-defined resource pools
HP Synergy uses software-defined resource pools that let administrators compose and recompose infrastructure resources on demand.
Question 7: In HP networking, what does the term 'uplink' refer to in the context of a top-of-rack (ToR) switch?
- A port connecting to end-user devices
- A port connecting to a higher-tier aggregation or core switch (Correct answer)
- A management port for out-of-band access
- A port used exclusively for storage traffic
Correct answer: A port connecting to a higher-tier aggregation or core switch
Uplink ports on a ToR switch connect to aggregation or core layer switches higher in the network hierarchy.
