Which device function allows a switch to learn the MAC address associated with a connected endpoint?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Examining the source MAC address of an incoming frame<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Examining only the destination IP address<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Sending every frame to the default gateway<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Reading the DNS server configuration<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. Examining the source MAC address of an incoming frame<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An Ethernet switch builds its MAC address table by examining the source MAC address of frames received on its interfaces. When a frame arrives, the switch associates the source MAC address with the ingress port and VLAN. This information allows the switch to make more efficient forwarding decisions for subsequent traffic destined for that MAC address. If the destination MAC address is unknown, the switch may flood the frame within the appropriate VLAN. MAC learning is therefore a fundamental Layer 2 switching function. It does not depend on DNS or the destination IP address, because Ethernet switching primarily operates using Layer 2 addressing.<\/span><\/p>\n<p><b>Question 22. What happens when a Layer 2 switch receives a frame whose destination MAC address is not currently present in its MAC address table?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The switch immediately discards the frame<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The switch sends it only to the default gateway<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The switch floods the frame within the applicable VLAN, excluding the receiving port<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The switch converts the frame into an IP packet<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. The switch floods the frame within the applicable VLAN, excluding the receiving port<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">When a switch does not know the destination MAC address, it treats the frame as an unknown unicast and normally floods it out other forwarding ports belonging to the same VLAN, while not sending it back through the port on which the frame arrived. This allows the intended destination to receive the frame and respond. The switch can then learn the destination&#8217;s source MAC address from the response and update its MAC address table. Flooding is limited to the relevant Layer 2 broadcast domain rather than being sent automatically to every VLAN or directly to the default gateway.<\/span><\/p>\n<p><b>Question 23. Which VLAN type is commonly used to carry management traffic for network infrastructure such as switches and access points?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Voice VLAN only<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Management VLAN<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Guest VLAN only<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Native VLAN exclusively<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Management VLAN<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A management VLAN is a logical VLAN dedicated to management-related communication with network infrastructure. Switches, access points, and other devices can be assigned management IP addresses within this VLAN, allowing administrators or management platforms to reach them without mixing management traffic with ordinary user traffic. Separating management traffic can improve organization and security and makes it easier to apply appropriate access controls. A voice VLAN is intended primarily for voice endpoints, while a guest VLAN normally isolates visitor traffic. The native VLAN is a trunking concept and does not inherently mean that the VLAN is being used for management.<\/span><\/p>\n<p><b>Question 24. In a campus design using VSF, what is a major operational benefit of combining compatible switches into a single virtual switching system?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> It eliminates the need for IP addressing<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It converts every Layer 2 port into a WAN interface<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It prevents wireless clients from roaming<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It allows multiple physical switches to be managed and operated as a logical switching system<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. It allows multiple physical switches to be managed and operated as a logical switching system<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Virtual Switching Framework (VSF) allows supported switches to operate together as a logical switching system. This can simplify management because administrators can work with the stack as a coordinated system rather than treating every physical member as an entirely independent switch. VSF can also support resiliency and simplify certain network designs by providing a unified control and management model. It does not eliminate the need for IP addressing or turn access ports into WAN interfaces. HPE Aruba Networking documentation identifies VSF support on several switch platforms and uses VSF stacks in campus access designs for resilient switching.<\/span><\/p>\n<p><b>Question 25. What is the main purpose of a Link Aggregation Group (LAG) between network devices?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To combine multiple physical links into a logical connection<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To assign DHCP addresses to clients<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To replace VLAN configuration<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To provide wireless encryption<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. To combine multiple physical links into a logical connection<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A Link Aggregation Group (LAG) combines multiple physical network links so they can operate as a logical connection between devices. This can provide additional resiliency because traffic can continue across remaining links if one physical connection fails. Depending on the implementation and traffic distribution method, aggregation can also provide greater aggregate capacity across multiple flows. LAGs are commonly used for switch uplinks and connections between network infrastructure devices. LAG itself does not provide DHCP, VLAN replacement, or wireless encryption. When dynamic negotiation is desired, LACP can be used to establish and maintain the aggregated link.<\/span><\/p>\n<p><b>Question 26. In an Ethernet network, what is the primary purpose of the default VLAN configuration on an access port?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To force the port to operate as a routed interface<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To place untagged endpoint traffic into a specific VLAN<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To encrypt all packets entering the port<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To automatically create a new IP subnet<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. To place untagged endpoint traffic into a specific VLAN<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An access port is commonly associated with a specific VLAN, and untagged traffic received from an endpoint is placed into that VLAN. This is typical for devices such as desktop computers, printers, or other endpoints that normally send ordinary Ethernet frames without an 802.1Q VLAN tag. The switch associates the traffic with the configured access VLAN before forwarding it within the Layer 2 network. VLAN membership does not automatically provide encryption or create an IP subnet. The IP subnet associated with the VLAN is configured separately through Layer 3 addressing and routing infrastructure.<\/span><\/p>\n<p><b>Question 27. Which wireless characteristic is most directly affected when an administrator increases the channel width from 20 MHz to a wider channel?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The number of SSIDs configured on the controller<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The MAC address length<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The amount of RF spectrum consumed by each channel<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The IP address assigned to the access point<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. The amount of RF spectrum consumed by each channel<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Increasing WLAN channel width means that a wireless transmission occupies a larger portion of the available RF spectrum. Wider channels can provide greater theoretical throughput under suitable conditions because more spectrum is available for transmitting data. However, wider channels also consume more RF resources and can reduce the number of independently usable channels in a given band. This can increase the potential for co-channel competition in dense deployments. Therefore, channel width should be selected according to the RF environment, client requirements, deployment density, and regulatory constraints rather than simply choosing the widest possible setting.<\/span><\/p>\n<p><b>Question 28. What is co-channel interference in a wireless network?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Interference caused exclusively by damaged Ethernet cables<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Interference that occurs when neighboring WLAN cells use the same RF channel and compete for airtime<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> A routing loop between two IP gateways<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> A failure of DHCP address allocation<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Interference that occurs when neighboring WLAN cells use the same RF channel and compete for airtime<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Co-channel interference or co-channel contention occurs when multiple WLAN cells operate on the same RF channel within overlapping coverage areas. Wi-Fi devices using the same channel generally coordinate access to the shared medium, so additional devices or neighboring networks can increase airtime contention. This can reduce effective throughput and increase latency, especially in dense deployments. Proper channel planning and transmit-power management can help reduce unnecessary overlap. Co-channel issues are different from problems caused by Ethernet cabling, IP routing loops, or DHCP failures. RF design therefore requires understanding channel allocation, coverage, interference, and client density.<\/span><\/p>\n<p><b>Question 29. What is the primary purpose of Dynamic Host Configuration Protocol (DHCP)?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To dynamically provide hosts with network configuration information<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To establish OSPF neighbor relationships<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To prevent switching loops<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To encrypt application traffic<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. To dynamically provide hosts with network configuration information<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">DHCP automatically provides network configuration information to clients. Depending on the deployment, a DHCP server can provide an IP address, subnet mask or prefix information, default gateway, DNS server addresses, lease information, and other parameters. This avoids the need to manually configure every endpoint. DHCP does not establish OSPF relationships, prevent Layer 2 loops, or encrypt application traffic. In campus networks, DHCP services may be centralized or distributed, and DHCP relay functionality can forward client requests across routed boundaries when the DHCP server resides on another network.<\/span><\/p>\n<p><b>Question 30. A DHCP server is located on a different IP subnet from the clients. Which function can allow DHCP requests to reach the remote server?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> MAC flooding<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DHCP relay<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> STP root election<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> WLAN channel bonding<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. DHCP relay<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">DHCP clients initially use broadcast communication to locate a DHCP server, but Layer 3 routers normally do not forward ordinary broadcasts between IP subnets. A DHCP relay function allows a Layer 3 device to receive the client request and forward the relevant DHCP information toward a DHCP server on another subnet. The relay also helps return the server&#8217;s response to the appropriate client network. This architecture allows organizations to centralize DHCP services instead of requiring a separate DHCP server on every subnet. DHCP relay is therefore particularly useful in routed campus environments containing multiple VLANs and IP networks.<\/span><\/p>\n<p><b>Question 31. Which routing table entry generally represents the route used when no more-specific destination route is available?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Host route<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Connected route<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Default route<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Loopback route<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Default route<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A default route is commonly used as the route of last resort. For IPv4, it is represented as 0.0.0.0\/0, while IPv6 uses ::\/0. When a router does not find a more-specific matching route for a destination, the default route can provide a forwarding path toward an upstream router or other next hop. Longest-prefix matching ensures that a more-specific route takes precedence over the default route. Default routes are especially common at branch offices and Internet edges where the local router does not need a complete table of every external destination.<\/span><\/p>\n<p><b>Question 32. What does the longest-prefix-match principle mean when a router selects an IPv4 route?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The route with the numerically largest metric is always selected<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The route with the shortest prefix is preferred<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Only static routes can be selected<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The most specific matching network prefix is preferred**<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. The most specific matching network prefix is preferred<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Routers use longest-prefix matching to select the most specific route that matches a packet&#8217;s destination address. A longer prefix represents a smaller and more specific network. For example, if a routing table contains both 10.0.0.0\/8 and 10.20.0.0\/16, traffic destined for 10.20.5.10 matches both entries, but the \/16 route is more specific and therefore wins the initial destination-prefix comparison. Only after determining the matching route set do other route-selection attributes become relevant. This principle is fundamental to understanding IP forwarding and why specific routes can override broader routes.<\/span><\/p>\n<p><b>Question 33. What is the primary purpose of an Access Control List (ACL) on a network device?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To control traffic according to defined matching conditions and actions<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To automatically increase link bandwidth<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To synchronize wireless channels<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To create physical network interfaces<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. To control traffic according to defined matching conditions and actions<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An Access Control List (ACL) defines traffic-matching conditions and associated actions, such as permitting or denying traffic. Depending on the platform and ACL type, rules can match characteristics including source and destination IP addresses, protocols, ports, and other packet attributes. ACLs are commonly used to restrict access between network segments, protect management interfaces, and implement security policies. ACLs do not create physical interfaces or increase bandwidth. Their effectiveness depends on correct rule order, matching criteria, direction, and placement. Administrators should also understand the platform&#8217;s implicit or explicit behavior when traffic does not match a configured rule.<\/span><\/p>\n<p><b>Question 34. In an enterprise WLAN, why is WPA3-Enterprise commonly paired with 802.1X-based authentication?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To prevent the need for any authentication server<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To provide enterprise authentication and stronger wireless security mechanisms<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To convert wireless frames into OSPF packets<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To disable encryption for faster throughput<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. To provide enterprise authentication and stronger wireless security mechanisms<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">WPA3-Enterprise is designed for enterprise wireless environments where stronger security and centralized identity-based access are required. It can be used with 802.1X and an authentication infrastructure such as RADIUS, allowing individual users or devices to authenticate rather than relying on one shared password. The wireless security framework also provides robust encryption and key-management mechanisms. Authentication and encryption address different aspects of WLAN security: authentication determines who or what is allowed to access the network, while the security protocol protects wireless communications. WPA3-Enterprise therefore fits environments requiring centralized, identity-based WLAN access control.<\/span><\/p>\n<p><b>Question 35. In AAA terminology, what does the second \u201cA\u201d represent?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Accounting<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Addressing<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Authorization<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Association<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Authorization<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">AAA stands for Authentication, Authorization, and Accounting. Authentication determines the identity of a user or device. Authorization determines what that authenticated identity is permitted to do, such as which network resources or services it may access. Accounting records information about access sessions or resource usage where supported. Keeping these functions conceptually separate is important when troubleshooting access problems. A user may successfully authenticate but still be denied a particular resource because the authorization policy does not grant the required permissions. RADIUS is commonly used to support centralized AAA services in enterprise wired and wireless networks.<\/span><\/p>\n<p><b>Question 36. What is the main purpose of ClearPass in an enterprise network access environment?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To replace every Ethernet switch<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To provide centralized network access control and policy enforcement based on identity and context<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To perform RF spectrum transmission<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To act only as a DNS cache<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. To provide centralized network access control and policy enforcement based on identity and context<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">HPE Aruba Networking ClearPass provides network access control capabilities that can use identity, device information, authentication results, and other contextual information to determine access policies. It can integrate with wired and wireless infrastructure and commonly works with authentication protocols such as RADIUS and 802.1X. ClearPass can help organizations apply different access policies to employees, guests, contractors, and devices. It is not a replacement for physical switches or an RF transmission system. In WLAN environments, ClearPass can be integrated with SSIDs and authentication workflows to provide centralized identity-based access control.<\/span><\/p>\n<p><b>Question 37. Which monitoring approach is most useful for identifying whether users are experiencing application or connectivity problems from their actual network locations?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> User-experience monitoring and synthetic testing<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Changing the switch hostname<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Disabling all VLANs<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Replacing every access point without testing<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. User-experience monitoring and synthetic testing<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">User-experience monitoring, including synthetic testing, helps administrators evaluate network and application performance from an endpoint or representative location. Rather than looking only at infrastructure statistics such as interface utilization, these tests can reveal whether users can actually reach important services and how those services perform. Measurements may include latency, packet loss, DNS performance, connectivity, and application response depending on the monitoring solution. This information can help distinguish infrastructure problems from service-specific problems. HPE6-A85 includes UXI test-result interpretation and network monitoring as explicit objectives, making user-experience analysis an important part of the exam preparation scope.<\/span><\/p>\n<p><b>Question 38. During troubleshooting, an administrator changes several configurations at once and the problem disappears.

It makes it harder to determine which change actually resolved the problem<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A structured troubleshooting process generally favors controlled changes so that the administrator can determine which action affects the problem. If several configurations are modified simultaneously, the problem may disappear, but the technician may not know which modification was responsible. This makes documentation, root-cause analysis, and future troubleshooting more difficult. It can also introduce unintended side effects that are not immediately visible. A better methodology is to gather evidence, establish a hypothesis, make an appropriate controlled change, test the result, and document the outcome. This approach creates a repeatable troubleshooting process and reduces unnecessary network disruption.<\/span><\/p>\n<p><b>Question 39. Which QoS mechanism can temporarily hold packets in a queue when an interface is congested so that selected traffic can receive preferential treatment?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> DNS<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> ARP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Packet queuing<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> LLDP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Packet queuing<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Packet queuing is a fundamental QoS mechanism used when traffic arrives faster than an interface can transmit it. Instead of treating every packet identically, a device can place traffic into queues according to classification or priority and determine which queue receives service first. This is particularly important for delay-sensitive applications such as voice and interactive video. Different queuing methods provide different scheduling behavior, so the exact implementation depends on the platform and policy. Queuing cannot create additional physical bandwidth; it manages the order and treatment of traffic when available transmission capacity becomes constrained.<\/span><\/p>\n<p><b>Question 40. A campus administrator wants wireless client traffic to be switched directly into the local wired VLAN at the access point instead of being tunneled to a central gateway.

Bridge mode<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">In bridge mode, the access point converts wireless 802.11 traffic into Ethernet traffic and bridges the client traffic toward the wired network. This allows the WLAN traffic to enter the appropriate VLAN at the AP&#8217;s wired uplink rather than requiring all client data to be tunneled to a centralized gateway. HPE Aruba Networking documentation describes bridged mode as a deployment in which the AP converts 802.11 frames to 802.3 Ethernet frames, while tunneled mode encapsulates wireless traffic toward a gateway.
