What does a wireless client do first when its countdown timer reaches zero and it receives a Transmit Opportunity (TXOP)?
- A . It immediately sends its Data Frames and receives an ACK from the AP.
- B . It sends a CTS-to-self announcement to the ESP gateway.
- C . It sends a CTS-to-self announcement to the AP and all other clients.
- D . It sends a reassociation request frame to the AP and sends its Data Frames.
A
Explanation:
When a wireless client’s countdown timer (also known as a backoff timer) reaches zero during contention-based access periods, and it receives a Transmit Opportunity (TXOP), it has the right to transmit its data frames on the medium. After sending the data frames, it expects an acknowledgment (ACK) from the Access Point (AP) to ensure the frames were received successfully.
Which Aruba technology provides load balancing across radio bands and AP radios?
- A . Aruba ESP
- B . Aruba ClientMatch
- C . Aruba AirWave
- D . Aruba Central
B
Explanation:
Aruba ClientMatch is a technology that continuously monitors client behavior and automatically adjusts client connections to optimize Wi-Fi performance. This includes steering clients to the least congested access point and the best radio on the WLAN, which effectively provides load balancing across different radio bands and AP radios.
What is indicated by a solid amber radio status LED on an Aruba AP?
- A . Not enough PoE is provided from the switch to power both radios of the AP
- B . The radio is working in mesh mode
- C . The radio is working the 5 GHz band only.
- D . The radio is enabled in monitor or spectrum analysis mode
A
Explanation:
On an Aruba AP, a solid amber radio status LED indicates: A. Not enough PoE is provided from the switch to power both radios of the AP
When the radio status LED on an Aruba AP shows a solid amber color, it typically signifies that the PoE (Power over Ethernet) supplied by the switch is insufficient to power both radios of the AP (usually the 2.4 GHz and 5 GHz bands). This may require checking the PoE budget of the switch or using a higher-powered PoE source.
Other options, such as the radio working in mesh mode, operating only in the 5 GHz band, or being enabled in monitor or spectrum analysis mode, typically do not result in the LED showing a solid amber color.
Match the phase of message processing with the Open Systems interconnection (OSl) layer.
Explanation:
In the OSI model, data is handled differently at each layer. Here is the correct matching of the phase of message processing with the OSI layer:
Physical Layer: Organizes the data into bits.
Data Link Layer: Organizes the data into frames.
Network Layer: Organizes the data into packets.
Transport Layer: Organizes the data into segments.
The Physical Layer is responsible for the transmission of raw bits over a physical medium. The Data Link Layer encapsulates packets into frames with MAC addresses for node-to-node communication. The Network Layer is responsible for packet forwarding including routing through intermediate routers. The Transport Layer provides reliable data transfer services to the upper layers and handles the segmentation and reassembly of data.
Which device configuration group types can a user define in Aruba Central during group creation? (Select two.)
- A . ESP group
- B . Security group
- C . Ul group
- D . Default group
- E . Template group
DE
Explanation:
In Aruba Central during group creation, users can define various configuration groups to manage settings for multiple devices. A Security group allows you to apply consistent security settings across devices, and a Template group enables you to apply pre-defined configurations to devices. These groups help streamline the deployment and management of network devices in Aruba Central.
What capabilities are included in Aruba’s ClearPass Policy Manager? (Choose two)
- A . Advanced cryptographic module validation.
- B . Guest access management with customizable web portals.
- C . Device profiling and fingerprinting.
- D . Direct cloud management integration.
