Authentic HP Certification Exam HPE3-U01 Questions Answers

According to the Aruba Network Technician (ACNT) documents and learning resources, the valid configurable “Client VLAN Assignment” options for a Bridge-based WLAN in Aruba Central are native VLAN, automatic VLAN, and static VLAN. These options allow you to specify how the VLAN ID for the WLAN clients is determined.

• Native VLAN: This option allows you to use the native VLAN of the AP’s Ethernet port as the VLAN ID for the WLAN clients. The native VLAN is the default VLAN that carries untagged traffic on a trunk port. This option is useful when you want to simplify the VLAN configuration and use the same VLAN for all the WLAN clients connected to the same AP.
• Automatic VLAN: This option allows you to use the VLAN ID assigned by a DHCP server to the WLAN clients. The DHCP server can use attributes such as MAC address, hostname, or vendor class to assign different VLAN IDs to different WLAN clients. This option is useful when you want to dynamically assign VLANs based on the client characteristics or policies.
• Static VLAN: This option allows you to specify a single VLAN ID for all the WLAN clients. You can either enter a VLAN ID manually or select a named VLAN from the drop-down list. A named VLAN is a VLAN that has a user-defined name associated with it for easy identification. This option is useful when you want to assign a fixed VLAN to a WLAN SSID.

Broadcast communication is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, using the electromagnetic spectrum (radio waves), in a one-to-many model1. A broadcast message is a message that is sent to all endpoints on the network, regardless of their address or identity2. An example of a broadcast message is an ARP request, which is used to find the MAC address of a device that has a specific IP address3. An ARP request is sent to the broadcast address of the network, which is usually the last address in the subnet (e.g., 192.168.1.255 for a /24 network). All devices on the network receive the ARP request and check if their IP address matches the one in the request. If so, they reply with their MAC address to the sender of the ARP request. If not, they ignore the request4. Therefore, an ARP request is an example of broadcast communication, while the other options are not. A DHCP offer is a message that is sent by a DHCP server to a specific client that requested an IP address5. An ICMP echo is a message that is sent by a device to test the connectivity and latency to another device. An HTTP Get is a message that is sent by a web browser to request a web page from a web server. These messages are not broadcast, but rather unicast, meaning they are sent to a single destination. References: 1: Broadcasting - Wikipedia 2: Broadcast communication network - Wikipedia 3: [Address Resolution Protocol - Wikipedia] 4: [How ARP Works - Cisco] 5: [DHCP - Wikipedia] : [Ping (networking utility) - Wikipedia] : [Hypertext Transfer Protocol - Wikipedia] : https://en.wikipedia.org/wiki/Address_Resolution_Protocol : https://www.cisco.com/c/en/us/support/docs/ip/dynamic-address-allocation- resolution/13718-5.html : https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol : https://en.wikipedia.org/wiki/Ping_(networking_utility) : https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol

To enable internet access on a multilayer switch, you need to configure a default route that points to the ISP router as the next hop. A default route is a special type of static route that matches any destination IP address that is not found in the routing table. The syntax for adefault route is ip route 0.0.0.0 0.0.0.0 , where 0.0.0.0 0.0.0.0 means any IP address and any subnet mask. Alternatively, you can use the slash notation 0.0.0.0/0 to represent the same thing. Therefore, the correct configuration line to enter on the switch is ip route 0.0.0.0/0 172.16.31.254, which means that any traffic that is not destined for a local network will be forwarded to the ISP router at 172.16.31.254.

The other options are incorrect because they either use the wrong syntax or the wrong IP address. Option A uses the route command instead of the ip route command, which is not valid on a multilayer switch. Option C uses the routing command instead of the ip route command, which is also not valid on a multilayer switch. Option D uses the ip routing command instead of the ip route command, which is used to enable routing on the switch, not to configure a default route. Option D also omits the dots in the IP address and the subnet mask, which makes it invalid.
