HP Aruba Campus Access Associate Exam Sample Questions (Q83-Q88):

NEW QUESTION # 83
How does the Aruba Central platform assist in managing Aruba networking devices?

  • A. By automating the firmware upgrades across all devices.
  • B. By distributing network traffic evenly across devices.
  • C. Central does not support device management functions.
  • D. Through centralized cloud-based management and monitoring.

Answer: D


NEW QUESTION # 84
What happens when the signal from an AP weakens by being absorbed as it moves through an object?

  • A. APs will use bonded channels to decrease latency to clients
  • B. Aruba Central dynamically moves clients to neighboring APs
  • C. Signal to Noise Ratio (SNR) decreases
  • D. Signal to Noise Ratio (SNR) increases

Answer: C

Explanation:
Explanation
Signal to noise ratio (SNR) is a measure that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels (dB). A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is corrupted or obscured by noise and may be difficult to distinguish or recover1. When the signal from an AP Access Point. AP is a device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards. weakens by being absorbed as it moves through an object, such as a wall or a furniture, the signal power decreases. This reduces the SNR and affects the quality of the wireless connection. The noise power may also increase due to interference from other sources, such as other APs or devices operating in the same frequency band2. Therefore, the correct answer is that SNR decreases when the signal from an AP weakens by being absorbed as it moves through an object. References: 1

NEW QUESTION # 85
Which are valid steps in troubleshooting Aruba Wireless Access Point connection issues? (Choose three)

  • A. Ensure that the AP is in compliance with the latest firmware updates.
  • B. Reset the AP to factory default settings.
  • C. Verify network cable integrity from the AP to the switch.
  • D. Check the power settings on the physical switch port connected to the AP.

Answer: A,C,D


NEW QUESTION # 86
What is used by network devices to send error and operational information related to IP communications?

  • A. Cyclic Redundancy Check (CRC)
  • B. User Datagram Protocol (UDP)
  • C. Internet Control Message Protocol (ICMP)
  • D. Frame Check Sequence (FCS)

Answer: C

Explanation:
ICMP (Internet Control Message Protocol) is used by network devices to send error and operational information related to IP communications. It is used to send messages like "destination unreachable" or
"time exceeded" when there are issues in IP communication


NEW QUESTION # 87
Which part of the WPA Key Hierarchy is used to encrypt and/or decrypt data''

  • A. Pairwise Temporal Key (PTK)
  • B. number used once (nonce)
  • C. Pairwise Master Key (PMK)
  • D. Key Confirmation Key (KCK)

Answer: A

Explanation:
The part of WPA Key Hierarchy that is used to encrypt and/or decrypt data is Pairwise Temporal Key (PTK).
PTK is a key that is derived from PMK Pairwise Master Key (PMK) is a key that is derived from PSK Pre- shared Key (PSK) is a key that is shared between two parties before communication begins , ANonce Authenticator Nonce (ANonce) is a random number generated by an authenticator (a device that controls access to network resources, such as an AP) , SNonce Supplicant Nonce (SNonce) is a random number generated by supplicant (a device that wants to access network resources, such as an STA) , AA Authenticator Address (AA) is MAC address of authenticator , SA Supplicant Address (SA) is MAC address of supplicant using Pseudo-Random Function (PRF). PTK consists of four subkeys:
* KCK Key Confirmation Key (KCK) is used for message integrity check
* KEK Key Encryption Key (KEK) is used for encryption key distribution
* TK Temporal Key (TK) is used for data encryption
* MIC Message Integrity Code (MIC) key
The subkey that is specifically used for data encryption is TK Temporal Key (TK). TK is also known as Pairwise Transient Key (PTK). TK changes periodically during communication based on time or number of packets transmitted.
The other options are not part of WPA Key Hierarchy because:
* PMK: PMK is not part of WPA Key Hierarchy, but rather an input for deriving PTK.
* KCK: KCK is part of WPA Key Hierarchy, but it is not used for data encryption, but rather for message integrity check.
* Nonce: Nonce is not part of WPA Key Hierarchy, but rather an input for deriving PTK.
