At which section of the Aruba Central WLAN configuration Wizard can you set the Role Based controls?
Answer(s): C
The Role Based Access Control (RBAC) feature allows network administrators to define specific roles and permissions for users, based on their organizational responsibilities. In Aruba Central, this feature is available under the Security section of the WLAN configuration Wizard.To configure RBAC in Aruba Central, you need to follow these steps:Log in to the Aruba Central web interface.Select the appropriate group or network from the Network Hierarchy.Click the "Configure" button next to the WLAN that you want to configure.In the WLAN configuration wizard, select the "Security" section.Under "Role Based Access Control," click the "Create New" button to add a new role.Enter a name for the role and select the appropriate permissions for that role.Click "Save" to create the new role.Once you have created the role, you can assign it to specific users or groups under the "Users" section of the WLAN configuration wizard.
Which organization is in charge of determining the International Standards?
Answer(s): A
The Institute of Electrical and Electronics Engineers (IEEE) is the organization responsible for developing and maintaining international standards for a wide range of technologies, including wireless networking standards such as Wi-Fi. The IEEE Standards Association (IEEE-SA) develops and publishes standards that are recognized globally and are used to ensure interoperability, reliability, and safety in various industries.The Wi-Fi Alliance is a global nonprofit organization that promotes and certifies Wi-Fi technology based on the IEEE 802.11 standards. While the Wi-Fi Alliance works closely with the IEEE and other organizations to develop Wi-Fi standards, it is not directly responsible for determining international standards.The Federal Communications Commission (FCC) is a government agency in the United States that regulates communications by radio, television, wire, satellite, and cable. While the FCC plays an important role in shaping policies related to wireless communications, it is not responsible for determining international standards.The Internet Engineering Task Force (IETF) is a global community of network designers, operators, vendors, and researchers that develops and promotes voluntary Internet standards and protocols. While the IETF works closely with the IEEE and other organizations to develop standards for the Internet, it is not directly responsible for determining international standards.
What is considered a Layer 2 component?
Answer(s): B
Layer 2 is the Data Link Layer of the OSI model, which is responsible for providing reliable transfer of data between adjacent network nodes. Layer 2 operates on MAC addresses and uses protocols such as Ethernet and Wi-Fi to transmit data over the physical network.A switch is a Layer 2 networking device that connects multiple devices on a local area network (LAN) and forwards data between them based on their MAC addresses. Switches operate at the Data Link Layer of the OSI model and use the MAC addresses of devices to determine where to send data packets.A router, on the other hand, is a Layer 3 networking device that connects multiple networks and forwards data packets between them based on their IP addresses. Routers operate at the Network Layer of the OSI model and use routing protocols such as OSPF and BGP to determine the best path for forwarding data packets.A transceiver is a device that converts electrical signals into optical signals and vice versa, allowing data to be transmitted over fiber optic cables. Transceivers can operate at different layers of the OSI model, depending on the type of network and transmission technology being used.A UTP cable is a type of twisted-pair copper cable that is commonly used for Ethernet connections. UTP cables are considered a Layer 1 component, as they provide the physical medium for transmitting data between network devices.
What is part of the 5 GHz band?
The 5 GHz band is a frequency range used for wireless networking and other wireless communications. It is divided into several sub-bands, each with different rules and restrictions on the use of frequencies and channels.U-NII stands for Unlicensed National Information Infrastructure and refers to the frequency ranges designated by the Federal Communications Commission (FCC) in the United States for unlicensed use. U-NII 5 refers to the range of frequencies from 5.725 GHz to 5.825 GHz, which is part of the 5 GHz band. This range includes several channels that are commonly used for Wi-Fi networking, such as channels 36, 40, 44, and 48.Channel 12 and 13 are part of the 2.4 GHz band, which is a separate frequency range used for wireless networking. Channels 149 to 161 are part of the UNII-3 band, which is a higher-frequency sub-band within the 5 GHz range. Channel 14 is not part of the 5 GHz or 2.4 GHz bands and is only used in Japan for wireless networking.
