Correct Answer: C

Explanation: The option that allows you to access the switch and see the boot options available for OS images and ServiceOS is Conductor USB-C console port. This option provides direct access to ServiceOS, which is an operating system

that runs on Aruba CX switches independently of AOS-CX Aruba Operating System CX (AOS-CX) is an operating system that runs on Aruba CX switches . ServiceOS provides low-level functions such as booting, firmware upgrades,

password recovery, hardware diagnostics, switch stacking, and system recovery. ServiceOS can be accessed through one of two methods:

Conductor USB-C console port: This method allows you to connect your PC or laptop to the USB-C console port on any member switch in a VSF stack using a USB-C cable. This method provides direct access to ServiceOS without requiring

any configuration or authentication on AOS-CX.

AOS-CX CLI: This method allows you to access ServiceOS through AOS-CX CLI using SSH or Telnet protocols. This method requires you to configure an IP address on AOS-CX and authenticate with your username and password. To see

the boot options available for OS images and ServiceOS, you need to access ServiceOS through Conductor USB-C console port and enter boot menu command at ServiceOS prompt.

The other options do not allow you to access the switch and see the boot options available for OS images and ServiceOS because:

Member 2 RJ-45 console port: This option allows you to connect your PC or laptop to the RJ-45 console port on any member switch in a VSF stack using an RJ-45 cable. This option provides direct access to AOS-CX CLI, not ServiceOS.

Member 2 switch mgmt port: This option allows you to connect your PC or laptop to the switch mgmt port on any member switch in a VSF stack using an Ethernet cable. This option provides indirect access to AOS-CX CLI through SSH or

Telnet protocols, not ServiceOS.

Conductor mgmt port using SSH: This option allows you to connect your PC or laptop to the mgmt port on any member switch in a VSF stack using an Ethernet cable. This option provides indirect access to AOS-CX CLI through SSH protocol,

not ServiceOS.

Correct Answer: BC

Explanation: Aruba Central allows you to create device configuration groups that define common settings for devices within each group. You can create different types of groupsdepending on your network requirements and management

preferences. Two types of groups that you can define in Aruba Central during group creation are:

Template group: A template group allows you to create configuration templates using variables and expressions that can be applied to multiple devices or device groups. Template groups provide flexibility and scalability for managing large-

scale deployments with similar configurations.

Default group: A default group is automatically created when you add devices to Aruba Central for the first time. The default group contains basic configuration settings that are applied to all devices that are not assigned to any other group.

You can modify or delete the default group as needed.

Correct Answer: B

Explanation: The main characteristic of the 6 GHz band that is true among the given options is that in North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the 5 GHz band. This characteristic provides more spectrum availability, less interference, and higher throughput for wireless devices that support Wi-Fi 6E Wi-Fi Enhanced (Wi-Fi 6E) is an extension of Wi-Fi 6 (802.11ax) standard that operates in the newly available unlicensed frequency spectrum around 6 GHz in addition to existing bands below it. Some facts about this characteristic are: In North America, there are up to seven non-overlapping channels available in each of three channel widths (20 MHz, 40 MHz, and 80 MHz) in the entire unlicensed portion of the new spectrum (5925?125 MHz). This means there are up to 21 non-overlapping channels available for Wi-Fi devices in total. In comparison, in North America, there are only nine non-overlapping channels available in each of two channel widths (20 MHz and 40 MHz) in the entire unlicensed portion of the existing spectrum below it (2400?483 MHz and 5150?825 MHz). This means there are only up to nine non-overlapping channels available for Wi-Fi devices in total. Therefore, in North America, there are more than twice as many non-overlapping channels available in each channel width in the new spectrum than in the existing spectrum below it. Specifically, there are more than twice as many non-overlapping channels available at 80 MHz width (seven) than at 40 MHz width (three) in the existing spectrum below it. The other options are not true because: Less RF signal is absorbed by objects in a 6 GHz WLAN: This option is false because higher frequency signals tend to be more absorbed by objects than lower frequency signals due to higher attenuation Attenuation is a general term that refers to any reduction in signal strength during transmission over distance or through an object or medium . Therefore, RF signals in a 6 GHz WLAN would be more absorbed by objects than RF signals in a lower frequency WLAN. The 6 GHz band is fully backward compatible with existing bands: This option is false because Wi-Fi devices need to support Wi-Fi 6E standard to operate in the new spectrum around 6 GHz . Existing Wi-Fi devices that do not support Wi-Fi 6Estandard cannot use this spectrum and can only operate in existing bands below it. Low Power Devices are allowed for indoor and outdoor usage: This option is false because Low Power Indoor Devices (LPI) are only allowed for indoor usage under certain power limits and registration requirements . Outdoor usage of LPI devices is prohibited by regulatory authorities such as FCC Federal Communications Commission (FCC) is an independent agency of United States government that regulates communications by radio, television, wire, satellite, and cable across United States . However, outdoor usage of Very Low Power Devices (VLP) may be allowed under certain power limits and without registration requirements.
