HPE3-U01 Sample Questions

  1. Q1

    A manufacturing company is upgrading its factory floor network. The environment contains heavy machinery that generates significant electromagnetic interference (EMI). The network links must connect switches that are 250 meters apart. Which media type is the optimal choice for this scenario?

    Show answer & explanation

    Correct answer: C

    Fiber optic cabling is completely immune to electromagnetic interference (EMI) because it uses light to transmit data rather than electrical signals. Furthermore, multimode fiber easily supports the 250-meter distance requirement, whereas copper Ethernet (UTP/STP) is limited to 100 meters per segment.

  2. Q2

    A university is deploying a new digital signage system across its campus. The central server must send the exact same high-definition video stream to 50 specific digital displays simultaneously without overwhelming the campus network core. Which transmission method should the network administrator utilize?

    Show answer & explanation

    Correct answer: D

    Multicast is a one-to-many communication model where a single stream of data is sent from a source and replicated by the network infrastructure only to the specific devices (the multicast group) that have requested it. This prevents the server from having to send 50 individual Unicast streams, preserving significant bandwidth.

  3. Q3

    While analyzing a packet capture, a network technician notices a destination MAC address ending in the hexadecimal value 'C8'. To configure a specific filter in a legacy monitoring tool, this value must be converted to decimal. What is the decimal equivalent of the hexadecimal value C8?

    Show answer & explanation

    Correct answer: B

    To convert hexadecimal C8 to decimal, calculate (C * 16^1) + (8 * 16^0). In hexadecimal, C equals 12. Therefore, (12 * 16) + (8 * 1) = 192 + 8 = 200.

  4. Q4

    A healthcare organization is expanding its physical footprint. They currently have a main hospital building containing 500 devices connected via high-speed Ethernet switches. They are purchasing a new clinic located 15 miles away, which will connect back to the main hospital using a leased line from a service provider.

    Which of the following statements accurately classifies the network components in this design?

    Show answer & explanation

    Correct answer: C

    A Local Area Network (LAN) connects devices within a limited geographical area, such as a single building or campus (e.g., the hospital and the clinic individually). A Wide Area Network (WAN) interconnects LANs over longer distances, typically utilizing telecommunications service provider circuits like the 15-mile leased line described in the scenario.

  5. Q5

    True or False: In the OSI model, the Transport layer is responsible for determining the best logical path for routing packets across multiple interconnected networks.

    Show answer & explanation

    Correct answer: B

    False. Path determination and logical addressing (IP routing) are the responsibilities of the Network layer (Layer 3). The Transport layer (Layer 4) is responsible for end-to-end communication, reliability, and flow control using protocols like TCP and UDP.

  6. Q6

    When a client device initiates a reliable connection to a web server, it utilizes the TCP 3-way handshake. Which of the following represents the correct sequence of messages exchanged during this process?

    Show answer & explanation

    Correct answer: C

    The TCP 3-way handshake begins with the client sending a SYN (Synchronize) packet. The server responds with a SYN-ACK (Synchronize-Acknowledge) packet. Finally, the client replies with an ACK (Acknowledge) packet, establishing the connection.
