Question 341

Which wireless security method uses SAE to provide password-based authentication for a personal wireless network?

1. WPA2-Enterprise
2. WPA3-Personal
3. Open authentication
4. MAC authentication

Correct Answer: 2

Explanation

WPA3-Personal uses Simultaneous Authentication of Equals, or SAE, for password-based wireless authentication. SAE improves the security characteristics of personal Wi-Fi networks compared with the traditional pre-shared-key exchange used by WPA2-Personal. It is designed to provide stronger protection against certain offline password-guessing attacks while maintaining a password-based user experience. WPA2-Enterprise normally uses 802.1X and an authentication server, open authentication does not provide equivalent wireless protection, and MAC authentication identifies devices by their MAC addresses. Therefore, WPA3-Personal is the appropriate security method when SAE-based personal authentication is required.

Question 342

Which wireless measurement compares the strength of a desired signal with the level of background noise?

1. Channel utilization
2. RSSI
3. SNR
4. Transmit power

Correct Answer: 3

Explanation

Signal-to-Noise Ratio, or SNR, compares the strength of the desired wireless signal with the surrounding noise level. A higher SNR generally indicates that the desired signal is easier for the receiver to distinguish from background RF energy. SNR is therefore an important measurement when troubleshooting wireless connectivity and performance. Channel utilization indicates how busy a channel is, RSSI represents received signal strength, and transmit power describes the power level used by a radio. Therefore, SNR is the appropriate metric when comparing a wireless signal against the background noise.

Question 343

Which feature allows a network administrator to identify directly connected neighboring network devices and their interface information?

1. LLDP
2. DHCP
3. RADIUS
4. OSPF

Correct Answer: 1

Explanation

LLDP, or Link Layer Discovery Protocol, allows network devices to advertise information about themselves to directly connected neighbors. Depending on the platform, this information can include device identity, port information, system capabilities, and management details. Administrators can use LLDP information when troubleshooting physical connections, documenting network topology, or verifying that devices are connected to expected interfaces. DHCP provides IP configuration, RADIUS supports centralized authentication, and OSPF exchanges routing information. Therefore, LLDP is the appropriate protocol for discovering directly connected neighboring devices and their interface information.

Question 344

Which switch technology provides redundancy by allowing multiple physical links to operate as a single logical connection?

1. STP
2. LACP
3. SNMP
4. ARP

Correct Answer: 2

Explanation

LACP allows multiple physical Ethernet links to be combined into a logical link aggregation group. This provides redundancy because traffic can continue across remaining member links if one physical connection fails. It can also increase aggregate bandwidth when multiple links are actively forwarding traffic. STP provides loop prevention, SNMP supports network monitoring, and ARP resolves IPv4 addresses to MAC addresses. Therefore, LACP is the appropriate technology when multiple physical links need to operate together as one logical connection while providing resilience and aggregated capacity.

Question 345

Which wireless feature allows a client device to spend scheduled periods in a low-power sleep state?

1. OFDMA
2. MU-MIMO
3. BSS coloring
4. Target Wake Time

Correct Answer: 4

Explanation

Target Wake Time, or TWT, allows compatible wireless clients and access points to coordinate scheduled wake periods. A client can spend more time in a low-power state and wake when communication is expected. This can reduce unnecessary radio activity and may be particularly useful for battery-powered devices such as IoT endpoints. OFDMA divides channel resources among users, MU-MIMO enables simultaneous spatial-stream communication, and BSS coloring helps distinguish overlapping wireless networks. Therefore, Target Wake Time is the feature associated with scheduled client wake periods and improved power efficiency.

Question 346

Which switch feature protects a Layer 2 network by preventing an access interface from becoming an unexpected spanning-tree path?

1. BPDU Guard
2. DHCP snooping
3. IGMP snooping
4. SNMP

Correct Answer: 1

Explanation

BPDU Guard is commonly used on access or edge ports where spanning-tree BPDUs are not expected. If a protected port receives a BPDU, the configured protective behavior can prevent that endpoint from influencing the spanning-tree topology. This is especially useful when access interfaces should connect only to end devices rather than switches or bridges. DHCP snooping protects DHCP traffic, IGMP snooping manages multicast forwarding, and SNMP provides monitoring information. Therefore, BPDU Guard is the appropriate feature for protecting an edge interface from unexpected spanning-tree participation.

Question 347

Which Aruba Central capability can provide detailed information about connected endpoints and their network behavior?

1. Sites
2. Client Insights
3. Firmware compliance
4. Configuration templates

Correct Answer: 2

Explanation

Client Insights provides visibility into connected endpoints and can help administrators understand client identity, characteristics, connectivity, and related network information. This visibility can assist with troubleshooting and identifying devices across the network. Sites organize infrastructure according to physical locations, firmware compliance helps monitor software versions, and configuration templates support standardized device configuration. Therefore, Client Insights is the appropriate Aruba Central capability when administrators need detailed information about connected endpoints and their network behavior.

Question 348

Which routing protocol is designed to exchange link-state information within an autonomous system?

1. OSPF
2. LACP
3. RADIUS
4. LLDP

Correct Answer: 1

Explanation

OSPF, or Open Shortest Path First, is a link-state interior gateway protocol used to exchange routing information within an autonomous system. OSPF routers build a topology database from received link-state information and calculate routes using the shortest-path algorithm. This allows routers to dynamically respond to topology changes and maintain routing information. LACP aggregates Ethernet links, RADIUS provides centralized authentication, and LLDP discovers directly connected neighbors. Therefore, OSPF is the appropriate protocol when a network requires dynamic link-state routing within an autonomous system.

Question 349

Which wireless setting determines the amount of RF energy transmitted by an access point radio?

1. Channel width
2. Channel utilization
3. Transmit power
4. RSSI

Correct Answer: 3

Explanation

Transmit power determines the RF energy level used by an access point radio when sending wireless transmissions. Proper transmit-power planning is important because excessively high power can increase interference and create coverage overlap, while insufficient power can reduce usable coverage. Channel width determines how much spectrum a channel occupies, channel utilization indicates how busy the channel is, and RSSI measures received signal strength at a client or receiver. Therefore, transmit power is the setting that directly controls the RF output level of the access point radio.

Question 350

Which mechanism can assign a different VLAN or access policy based on the identity of an authenticated user or device?

1. Static routing
2. Role-based access control
3. Port mirroring
4. NTP

Correct Answer: 2

Explanation

Role-based access control allows network access decisions to depend on the identity or assigned role of a user or device. In an authentication-based deployment, the network can associate a role with appropriate policies, VLAN access, firewall rules, or other permissions. This provides more granular control than giving every authenticated endpoint identical access. Static routing determines fixed network paths, port mirroring copies traffic for analysis, and NTP synchronizes system time. Therefore, role-based access control is the appropriate mechanism for applying different access policies according to authenticated identity or role.

Question 351

Which protocol is commonly used to securely manage an Aruba switch through a command-line interface?

1. SSH
2. Telnet
3. TFTP
4. SNMP

Correct Answer: 1

Explanation

SSH provides encrypted remote command-line access to network devices. Administrators can use SSH to securely manage supported Aruba switches and other infrastructure without transmitting management credentials and session data as plain text. This makes SSH preferable to legacy Telnet for remote CLI administration. TFTP is primarily a basic file-transfer protocol and does not provide an interactive secure management session, while SNMP is generally used for monitoring and management information rather than interactive CLI access. Therefore, SSH is the appropriate protocol for secure command-line management.

Question 352

Which technology can provide centralized authentication for administrators accessing network infrastructure devices?

1. DHCP
2. RADIUS
3. TACACS+
4. LLDP

Correct Answer: 3

Explanation

TACACS+ is commonly used for centralized authentication and authorization of administrators accessing network infrastructure. It can provide centralized control over administrative access and supports separation of authentication, authorization, and accounting functions. This makes it useful in environments where organizations want centralized management of administrator credentials and privileges. DHCP provides IP configuration, RADIUS is widely used for network access authentication, and LLDP provides neighbor discovery. Therefore, TACACS+ is the appropriate technology when centralized administrative access control is required for network devices.

Question 353

Which feature can prevent a switch port from learning more MAC addresses than the configured limit?

1. OSPF
2. Port security
3. NTP
4. LLDP

Correct Answer: 2

Explanation

Port security can restrict the number of source MAC addresses that a switch interface is permitted to learn or accept. This helps control which devices are allowed to use an access port and can reduce the risk associated with unauthorized endpoint connections. Administrators can configure permitted MAC addresses or define a maximum number of addresses depending on platform capabilities. OSPF handles dynamic routing, NTP synchronizes clocks, and LLDP discovers neighboring devices. Therefore, port security is the appropriate feature for limiting the number of MAC addresses learned on a switch port.

Question 354

Which wireless standard feature divides a wireless channel into smaller resource units that can be assigned to different clients?

1. MU-MIMO
2. TWT
3. OFDMA
4. BSS coloring

Correct Answer: 3

Explanation

OFDMA, or Orthogonal Frequency Division Multiple Access, divides a wireless channel into smaller resource units that can be assigned to different clients. This allows an access point to efficiently schedule transmissions for multiple users instead of requiring every client to occupy the entire available channel for each transmission. MU-MIMO uses spatial streams for simultaneous communication, TWT schedules client wake periods, and BSS coloring helps identify transmissions from different BSSs. Therefore, OFDMA is the technology specifically associated with dividing channel resources into smaller units for multiple clients.

Question 355

Which protocol can provide automatic IP addressing information such as an IPv4 address, subnet mask, and default gateway?

1. DHCP
2. ARP
3. NTP
4. LLDP

Correct Answer: 1

Explanation

DHCP, or Dynamic Host Configuration Protocol, automatically provides clients with network configuration information. Depending on the DHCP scope and options configured, a client can receive an IPv4 address, subnet mask, default gateway, DNS server information, lease duration, and other parameters. This reduces the need to manually configure every endpoint and helps administrators manage address allocation centrally. ARP resolves IPv4 addresses to MAC addresses, NTP synchronizes system clocks, and LLDP provides neighbor information. Therefore, DHCP is the appropriate protocol for automatically providing IPv4 network configuration information.

Question 356

Which feature can copy traffic from one or more switch interfaces to another interface for packet analysis?

1. Storm control
2. Port security
3. Port mirroring
4. Root Guard

Correct Answer: 3

Explanation

Port mirroring allows a switch to copy selected traffic from one or more source interfaces or VLANs to a designated destination interface. A monitoring device connected to the destination interface can capture and analyze the copied packets. This can be useful for troubleshooting connectivity problems, examining protocols, investigating performance issues, or validating traffic behavior. Storm control limits excessive Layer 2 traffic, port security controls source MAC addresses, and Root Guard protects the intended spanning-tree root. Therefore, port mirroring is the appropriate feature for sending copied switch traffic to a monitoring interface.

Question 357

Which wireless security mode is designed for enterprise networks using 802.1X authentication?

1. WPA3-Enterprise
2. WPA3-Personal
3. Open
4. Enhanced Open

Correct Answer: 1

Explanation

WPA3-Enterprise is designed for enterprise wireless environments that use centralized authentication and 802.1X-based access control. It can work with an authentication infrastructure such as a RADIUS server to validate users or devices. This provides organizations with individual authentication rather than relying on one shared personal password. WPA3-Personal uses SAE for personal password-based access, Open networks do not provide equivalent authentication protection, and Enhanced Open improves privacy for open networks without providing enterprise 802.1X authentication. Therefore, WPA3-Enterprise is the appropriate security mode for enterprise 802.1X deployments.

Question 358

Which Layer 2 protocol can help a switch identify whether neighboring devices support specific capabilities such as bridging or routing?

1. DHCP
2. LLDP
3. RADIUS
4. ARP

Correct Answer: 2

Explanation

LLDP allows network devices to advertise information about their identity, interfaces, system capabilities, and other supported characteristics to directly connected neighbors. Administrators can use this information to understand physical topology and verify that devices are connected as expected. LLDP is especially useful when documenting switch-to-switch and switch-to-access-point relationships. DHCP provides IP configuration, RADIUS supports centralized authentication, and ARP maps IPv4 addresses to MAC addresses. Therefore, LLDP is the appropriate Layer 2 protocol for discovering neighboring device information and capabilities.

Question 359

Which mechanism helps an IPv6 host discover neighboring devices and resolve a local IPv6 address to a link-layer address?

1. DHCPv4
2. ARP
3. IPv6 Neighbor Discovery
4. STP

Correct Answer: 3

Explanation

IPv6 Neighbor Discovery provides functions that are performed by ARP in IPv4 environments, including discovering neighboring nodes and resolving IPv6 addresses to link-layer addresses. It uses ICMPv6 messages such as Neighbor Solicitation and Neighbor Advertisement. Neighbor Discovery also supports additional IPv6 functions, including router discovery and duplicate address detection. DHCPv4 is associated with IPv4 address configuration, ARP is an IPv4 address-resolution protocol, and STP prevents Layer 2 switching loops. Therefore, IPv6 Neighbor Discovery is the appropriate mechanism for local IPv6 neighbor and link-layer address discovery.

Question 360

Which Aruba Central capability can help standardize configuration across multiple network devices?

1. Configuration templates
2. RSSI
3. MAC address table
4. Channel utilization

Correct Answer: 1

Explanation

Configuration templates in Aruba Central can help administrators standardize settings across supported network devices. Instead of manually entering the same configuration on every device, administrators can use centralized templates to apply consistent parameters to appropriate groups or deployments. This can improve operational consistency and reduce repetitive configuration work. RSSI is a wireless signal-strength measurement, a MAC address table contains Layer 2 forwarding information, and channel utilization measures wireless channel activity. Therefore, configuration templates are the appropriate Aruba Central capability for standardizing device configuration.
