NEW QUESTION # 70
The customer requires two Aruba CX 6200F 48G switches to be connected to each other with a distance of 80m/252ft between wiring closets. Switches need to have reservation for VSF expansion with ring topology in each cabinet.
What is a valid configuration for a redundant link-aggregation port configuration?
Answer: A
Explanation:
For an 80m distance between wiring closets, using SFP+ transceivers is appropriate as they can support longer distances than standard copper interfaces. Ports 1/1/51 and 1/1/52 are typically reserved for uplinks on Aruba CX 6200F 48G switches and can support SFP+ transceivers, making them suitable for a redundant link-aggregation port configuration.
NEW QUESTION # 71
Where are wireless client roaming decisions made?
Answer: C
Explanation:
Wireless client roaming decisions are made by the client device based on its own criteria, such as signal strength, noise level, data rate, etc. The network can influence the client's roaming decision by providing information such as neighbor reports, load balancing, band steering, etc., but the final decision is up to the client.
NEW QUESTION # 72
Which part of the WPA Key Hierarchy is used to encrypt and/or decrypt data''
Answer: C
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.

Drag and Drop Question
Match the phase of message processing with the Open Systems interconnection (OSl) layer.
Answer:
Explanation:
Explanation:
Layer: 1) Physical layer Phase of Message Processing: d) Organize the data into bits Layer: 2) Data Link layer Phase of Message Processing: c) Organize the data into frames Layer: 3) Network layer Phase of Message Processing: b) Organize the data into packets Layer: 4) Transport layer Phase of Message Processing: a) Organize the data into segments The OSI model divides the networking process into seven layers, each representing a different step of the transmission chain. Each layer has its own function and is responsible for well-defined tasks. User data passes sequentially from the highest layer down through the lower layers until the device transmits it externally. The lowest layer, the physical layer, converts the data into bits that can be sent over a physical medium. The second layer, the data link layer, organizes the bits into frames that can be transmitted over a link between two nodes. The third layer, the network layer, organizes the frames into packets that can be routed across a network of nodes. The fourth layer, the transport layer, organizes the packets into segments that can provide reliable and error- free communication between two end points.
NEW QUESTION # 74
What happens when the signal from an AP weakens by being absorbed as it moves through an object?
Answer: C
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.
