Which OSI model layer is primarily responsible for logical addressing and routing packets between different networks?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Data Link layer<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Network layer<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Transport layer<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Session layer<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Network layer<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The network layer (Layer 3) is responsible for logical addressing and determining paths between different networks. IP addressing and routing are fundamental Layer 3 functions. Routers and Layer 3 switches use destination IP addresses to determine where packets should be forwarded. The Data Link layer, by comparison, handles local frame delivery using technologies such as Ethernet and MAC addresses. The Transport layer provides services such as TCP reliability and UDP delivery. Understanding the distinction between Layer 2 and Layer 3 is particularly important for HPE6-A85 because switching, VLANs, routing, and inter-VLAN communication are major areas of the exam.<\/span><\/p>\n<p><b>Question 2. Which Ethernet technology allows multiple VLANs to be carried across a single physical link between network devices?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> 802.1Q VLAN tagging<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> CSMA\/CD<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> LLDP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DHCP relay<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. 802.1Q VLAN tagging<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">IEEE 802.1Q tagging allows multiple VLANs to traverse the same physical Ethernet link by adding VLAN identification information to Ethernet frames. Such a link is commonly configured as a trunk or tagged interface. The receiving switch uses the VLAN identifier to determine the appropriate logical broadcast domain. This is especially useful between switches, between switches and routers, and in other situations where several VLANs need to share one physical connection. CSMA\/CD is an older Ethernet access mechanism, LLDP is used for neighbor discovery, and DHCP relay forwards DHCP requests between different IP networks. None of those technologies performs VLAN tagging.<\/span><\/p>\n<p><b>Question 3. What is the primary purpose of a VLAN in a campus network?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Increase the physical cable length<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Replace IP addressing<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Logically separate devices into different Layer 2 broadcast domains<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Encrypt all Ethernet frames<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Logically separate devices into different Layer 2 broadcast domains<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A VLAN logically divides a switched network into separate Layer 2 broadcast domains. Devices belonging to different VLANs are logically separated even when they are connected to the same physical switching infrastructure. For example, an organization might place employees, guests, voice devices, and IoT equipment into separate VLANs. Communication between different VLANs requires Layer 3 routing. VLANs therefore improve network organization, segmentation, and control without requiring a physically separate switch for every group. VLANs do not themselves provide encryption, replace IP addressing, or extend the physical characteristics of Ethernet cabling.<\/span><\/p>\n<p><b>Question 4. What is the primary purpose of Spanning Tree Protocol in a switched Ethernet network?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Assign IP addresses to switches<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Prevent Layer 2 switching loops<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Encrypt traffic between switches<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Select the fastest Internet connection<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Prevent Layer 2 switching loops<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Spanning Tree Protocol (STP) prevents Layer 2 loops when redundant paths exist between switches. Redundant links are valuable for resiliency, but without loop-prevention mechanisms, Ethernet frames can circulate repeatedly through the network. STP creates a loop-free logical topology by placing selected redundant paths into a non-forwarding state while maintaining the ability to activate them when the active path fails. Modern networks may use variants such as RSTP or MSTP to improve convergence and scalability. STP is therefore primarily a Layer 2 loop-prevention technology rather than an IP addressing, encryption, or Internet-path selection mechanism.<\/span><\/p>\n<p><b>Question 5. Which technology is designed to combine multiple physical Ethernet links into one logical link for increased resiliency and potentially greater aggregate bandwidth?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> LACP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> ARP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DHCP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> ICMP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. LACP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Link Aggregation Control Protocol (LACP) is used to dynamically negotiate and maintain a link aggregation group. Multiple physical Ethernet interfaces can operate as a logical bundle, providing redundancy if one physical link fails and allowing traffic to be distributed across available links according to the platform&#8217;s load-balancing method. LACP is standardized as IEEE 802.1AX. ARP resolves IPv4 addresses to MAC addresses, DHCP provides network configuration information, and ICMP supports control and diagnostic messaging. In campus networks, link aggregation is commonly used between switches or between network devices where both additional resiliency and aggregate link capacity are desirable.<\/span><\/p>\n<p><b>Question 6. An administrator needs hosts in VLAN 20 and VLAN 30 to communicate with each other. Which function is required?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> MAC learning only<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Layer 3 inter-VLAN routing<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> LLDP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Spanning Tree only<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Layer 3 inter-VLAN routing<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Hosts in separate VLANs belong to different Layer 2 broadcast domains and cannot communicate directly through ordinary Layer 2 switching. Inter-VLAN routing provides the required Layer 3 function. A Layer 3 switch or router can provide logical Layer 3 interfaces associated with the VLANs and route packets between their IP subnets. For example, VLAN 20 might use one IP subnet while VLAN 30 uses another. When a host sends traffic to a destination in the other subnet, it forwards the packet toward its default gateway, which performs the routing decision. VLAN configuration alone does not provide communication between separate VLANs.<\/span><\/p>\n<p><b>Question 7. Which IPv4 address is in the private address range commonly used for internal networks?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> 8.8.8.8<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 172.32.10.5<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 192.168.25.10<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 203.0.113.10<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. 192.168.25.10<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The IPv4 private address ranges defined by RFC 1918 are 10.0.0.0\/8, 172.16.0.0\/12, and 192.168.0.0\/16. Therefore, 192.168.25.10 is a private IPv4 address. Private addresses are commonly used inside enterprise and home networks and are not directly routable across the public Internet. The address 8.8.8.8 is a publicly routable address, while 172.32.10.5 falls outside the private 172.16.0.0 through 172.31.255.255 range. The 203.0.113.0\/24 range is reserved for documentation and examples rather than normal private addressing.<\/span><\/p>\n<p><b>Question 8. Which protocol is commonly used to discover directly connected neighboring network devices and exchange basic device information?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> FTP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> SMTP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> SNMP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> LLDP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. LLDP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Link Layer Discovery Protocol (LLDP) is an IEEE standard used by network devices to advertise information about themselves to directly connected neighbors. Information can include the device identity, port information, system capabilities, and other operational details. Network administrators can use LLDP to understand physical and logical connectivity and to assist with troubleshooting. SNMP is primarily a network management and monitoring protocol, while FTP is used for file transfer and SMTP is used for email transmission. LLDP operates at the link layer and is particularly useful when documenting or diagnosing the topology of a campus network.<\/span><\/p>\n<p><b>Question 9. What is the main purpose of a default gateway configured on an end host?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To forward traffic destined for other IP networks<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To assign the host&#8217;s MAC address<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To identify the host&#8217;s VLAN automatically<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To provide DNS name resolution<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. To forward traffic destined for other IP networks<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An end host uses its default gateway when it needs to send traffic to a destination outside its local IP subnet. The gateway is normally the IP address of a router or Layer 3 switch interface on the host&#8217;s local network. If the destination is within the same subnet, the host can communicate directly at Layer 2 after resolving the destination&#8217;s MAC address. If the destination is remote, the host sends the frame to the MAC address associated with its default gateway. The default gateway does not assign MAC addresses or provide DNS by itself; those are separate network functions.<\/span><\/p>\n<p><b>Question 10. Which statement best describes OSPF in a basic enterprise network?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> It is a Layer 2 loop-prevention protocol<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It is a dynamic routing protocol that uses link-state information<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It is a wireless encryption standard<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It is a protocol used only for assigning IP addresses<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. It is a dynamic routing protocol that uses link-state information<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Open Shortest Path First (OSPF) is a dynamic Interior Gateway Protocol that uses a link-state approach. Routers participating in OSPF exchange information about network links and build a link-state database representing the topology. They then use the Shortest Path First algorithm to calculate suitable routes. OSPF can automatically adapt to topology changes and is commonly used in enterprise networks. It is fundamentally different from STP, which addresses Layer 2 loops. It is also unrelated to wireless encryption or DHCP. HPE&#8217;s campus-access training includes basic IP routing and single-area OSPF as part of the foundational networking curriculum.<\/span><\/p>\n<p><b>Question 11. In a wireless LAN, what does the term SNR primarily describe?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The number of connected clients<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The difference between a switch&#8217;s uplink and downlink speeds<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The relationship between the desired wireless signal and background noise<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The number of available SSIDs<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. The relationship between the desired wireless signal and background noise<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Signal-to-Noise Ratio (SNR) describes the relationship between the strength of a desired wireless signal and the level of background radio-frequency noise. A higher SNR generally provides a better environment for reliable wireless communication because the intended signal is more distinguishable from unwanted noise. SNR is normally expressed in decibels (dB). Wireless performance is affected by several RF factors, including signal strength, noise, channel utilization, interference, client capabilities, and physical obstacles. Therefore, simply observing signal strength is not always enough to understand WLAN quality. SNR is an important measurement when evaluating wireless coverage and performance.<\/span><\/p>\n<p><b>Question 12. Which frequency band is commonly associated with greater channel availability than the traditional 2.4 GHz band and is widely used by modern enterprise WLANs?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> 5 GHz<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 60 Hz<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 900 kHz<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 125 MHz<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. 5 GHz<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The 5 GHz band provides substantially more usable WLAN spectrum and generally more non-overlapping channel options than the traditional 2.4 GHz band, depending on the regulatory domain and configured channel widths. This can help reduce congestion in environments where many wireless networks compete for spectrum. The 2.4 GHz band has longer propagation characteristics and can provide useful coverage, but it has fewer commonly used non-overlapping channels and is often more congested because many devices operate there. WLAN design must consider regulatory requirements, channel availability, client capabilities, transmit power, coverage, and interference rather than selecting a frequency band in isolation.<\/span><\/p>\n<p><b>Question 13. What is the primary purpose of an SSID in a WLAN?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> It uniquely identifies a physical Ethernet cable<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It identifies a wireless network that clients can discover and associate with<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It provides the default gateway IP address<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It replaces WPA authentication<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. It identifies a wireless network that clients can discover and associate with<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An SSID (Service Set Identifier) is the name associated with a wireless network. Clients use the SSID to identify the WLAN they want to join. An organization may create separate SSIDs for employees, guests, or specialized devices and apply different security or access policies to each one. The SSID itself is not an authentication mechanism and does not provide encryption. Wireless security is provided through mechanisms such as WPA2 or WPA3 and associated authentication methods. Similarly, an SSID does not represent an IP gateway or physical Ethernet connection; it is a logical identifier used in the WLAN environment.<\/span><\/p>\n<p><b>Question 14. Which security mechanism allows an enterprise WLAN to authenticate individual users or devices through a centralized authentication infrastructure?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> CSMA\/CA<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> STP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 802.1X<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 802.1Q<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. 802.1X<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">IEEE 802.1X provides port-based network access control and is widely used in enterprise WLAN environments for identity-based authentication. It works with an authentication framework such as EAP and commonly communicates with a centralized AAA\/RADIUS server. Instead of giving every employee the same shared wireless password, an organization can authenticate individual users or devices using centrally managed credentials or certificates. This provides better control and accountability. 802.1X should not be confused with 802.1Q, which is associated with VLAN tagging. STP prevents Layer 2 loops, while CSMA\/CA is associated with wireless medium access.<\/span><\/p>\n<p><b>Question 15. What is the primary role of RADIUS in an enterprise network?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> It provides centralized authentication, authorization, and accounting services<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It prevents Layer 2 loops<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It assigns Ethernet MAC addresses<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It performs wireless channel scanning<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. It provides centralized authentication, authorization, and accounting services<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Radius is commonly used as a centralized AAA protocol for network access. Authentication determines who or what is requesting access, authorization determines what access is permitted, and accounting can record information about sessions and usage. In enterprise WLAN deployments, network access devices can communicate with a RADIUS server to authenticate users through 802.1X. This architecture allows administrators to manage access centrally rather than configuring separate credentials on every network device. RADIUS is not responsible for preventing switching loops, assigning Ethernet MAC addresses, or performing RF channel scanning.<\/span><\/p>\n<p><b>Question 16. A network administrator wants to monitor whether a network device is reachable and collect management information such as interface statistics. Which technology is commonly appropriate?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> SNMP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> ARP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> 802.1Q<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> RSTP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. SNMP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Simple Network Management Protocol (SNMP) is commonly used to monitor and manage network devices. An SNMP management platform can retrieve information such as interface status, traffic counters, CPU utilization, and other operational statistics, depending on the device and configured monitoring objects. SNMP can therefore help administrators identify performance problems and operational changes across a network. ARP is used for IPv4 address-to-MAC resolution, 802.1Q handles VLAN tagging, and RSTP provides rapid Layer 2 loop prevention. Network monitoring is one of the important areas associated with HPE6-A85, including the use of management and monitoring tools.<\/span><\/p>\n<p><b>Question 17. A user reports that a wired computer cannot reach any network resource. What should generally be checked FIRST during basic troubleshooting?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Replace the network switch immediately<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Verify the physical connection and link status<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Reconfigure the entire VLAN infrastructure<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Disable all security controls<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Verify the physical connection and link status<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A structured troubleshooting methodology normally begins with the simplest and most fundamental possibilities. For a wired connectivity problem, checking the physical connection and link status is an appropriate first step. The technician can verify that the cable is connected correctly, the switch port is active, and the endpoint&#8217;s network interface is operational. If Layer 1 connectivity is unavailable, higher-layer troubleshooting will not resolve the problem. After confirming the physical layer, the technician can progress through VLAN assignment, IP addressing, default gateway, DNS, routing, authentication, and application-level checks. This systematic approach reduces unnecessary configuration changes and speeds diagnosis.<\/span><\/p>\n<p><b>Question 18. What is the primary purpose of Quality of Service (QoS) in a congested network?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To assign MAC addresses automatically<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To eliminate the need for routing<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To prioritize and manage traffic according to defined policies<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To create additional physical bandwidth automatically<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. To prioritize and manage traffic according to defined policies<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Quality of Service (QoS<\/span><b>)<\/b><span style=\"font-weight: 400;\"> provides mechanisms for classifying, marking, queuing, prioritizing, and sometimes rate-limiting traffic. During congestion, QoS policies can ensure that important or delay-sensitive applications receive appropriate treatment. For example, voice traffic may require low delay and jitter, while bulk file transfers can tolerate more delay. QoS cannot create additional physical bandwidth; instead, it manages how available resources are allocated. Effective QoS requires identifying traffic correctly and applying appropriate policies at relevant points in the network. Understanding classification, marking, queuing, and rate limiting is therefore useful when preparing for the HPE6-A85 performance-optimization objectives.<\/span><\/p>\n<p><b>Question 19. Which HPE Aruba Networking solution is primarily intended to provide centralized cloud-based management and monitoring of supported network infrastructure?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> HPE Aruba Networking Central<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> STP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> LACP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> ARP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. HPE Aruba Networking Central<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">HPE Aruba Networking Central is a cloud-based network management and operations platform used to manage and monitor supported Aruba Networking infrastructure. Depending on the deployed products and configuration, administrators can use Central for device onboarding, configuration, monitoring, troubleshooting, reporting, and network-health visibility. This centralized approach can simplify management across distributed campus environments. STP and LACP are network protocols rather than centralized management platforms, while ARP performs IPv4 address-to-MAC resolution. HPE&#8217;s Campus Access Fundamentals course specifically includes Central for device management, onboarding, groups, configuration modes, licensing, and monitoring as part of the campus-access technology set.<\/span><\/p>\n<p><b>Question 20. An administrator needs to provide redundant default-gateway functionality so that hosts can continue using a gateway if one network device fails. Which technology is most directly suited to this requirement?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> LLDP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> VRRP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DHCP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> SNMP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. VRRP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Virtual Router Redundancy Protocol (VRRP) provides first-hop gateway redundancy by allowing multiple routers or Layer 3 devices to participate in a virtual router configuration. Hosts can use the virtual IP address as their default gateway rather than depending on the physical address of only one device. If the active device becomes unavailable, another participating device can take over the virtual gateway function. This improves network resiliency without requiring hosts to change their configured default gateway. LLDP is used for neighbor discovery, DHCP provides network configuration, and SNMP is used for monitoring and management. VRRP is therefore directly aligned with gateway redundancy requirements.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>View Full HP HPE6-A85 Exam Dumps and Practice Test Dumps.
