Question 21

An Aruba administrator needs to authenticate wireless users through an external authentication server and assign network access based on the authentication result. Which combination is most appropriate?

1. DNS and DHCP
2. RADIUS and role assignment
3. SNMP and Syslog
4. NTP and FTP

Correct Answer: 2

Explanation

RADIUS provides centralized authentication, authorization, and accounting for network access, while Aruba role assignment can apply appropriate access policies after the user is authenticated. This combination allows an administrator to distinguish users based on authentication information and apply different network privileges. DNS and DHCP provide name resolution and network configuration, but they do not perform centralized user authentication. SNMP and Syslog are primarily used for monitoring and logging. NTP and FTP serve time synchronization and file-transfer purposes. Therefore, RADIUS combined with role assignment is appropriate for identity-based network access control.

Question 22

An administrator wants to configure an Aruba switch port so that it carries traffic from multiple VLANs to another network device. Which port type should be configured?

1. Access
2. Loopback
3. Routed
4. Trunk

Correct Answer: 4

Explanation

A trunk port is designed to carry traffic belonging to multiple VLANs across a single physical link. VLAN identification is maintained as traffic traverses the trunk, allowing connected network devices to exchange traffic for multiple logical networks. An access port is normally associated with a single VLAN. A routed port operates at Layer 3 and does not provide traditional VLAN trunking, while a loopback interface is a logical interface used for management or routing purposes. Therefore, an Aruba switch port connecting devices that need to exchange multiple VLANs should be configured as a trunk.

Question 23

A wireless administrator wants to identify clients that are connected to a specific SSID and determine their assigned IP addresses. Which information is most useful?

1. Client monitoring information
2. NTP configuration
3. Routing protocol timers
4. DNS zone information

Correct Answer: 1

Explanation

Client monitoring information provides details about wireless clients associated with an SSID. Depending on the Aruba platform and management interface, administrators can view information such as client MAC address, IP address, authentication status, signal characteristics, VLAN, and associated access point. NTP configuration is used for time synchronization, routing protocol timers control routing operations, and DNS zone information is related to name resolution. Therefore, client monitoring information is the appropriate source when an administrator needs to identify connected wireless clients and examine their network details.

Question 24

An administrator wants to prevent a guest wireless user from accessing internal corporate resources while still allowing Internet access. Which design is most appropriate?

1. Place guests in the same VLAN as employees
2. Disable the guest SSID
3. Place guests in a dedicated VLAN with appropriate access policies
4. Assign guests static IP addresses from the corporate subnet

Correct Answer: 3

Explanation

A dedicated guest VLAN combined with appropriate firewall or access-control policies provides logical separation between guest users and corporate resources. Guest traffic can be routed toward the Internet while access to internal networks is restricted according to the organization’s security requirements. Placing guests and employees in the same VLAN makes isolation more difficult, while disabling the guest SSID prevents guest access entirely. Assigning guest devices addresses from the corporate subnet also fails to provide meaningful network separation. Therefore, a dedicated guest VLAN with appropriate access policies is a suitable design.

Question 25

An Aruba administrator observes that many wireless clients are experiencing poor performance because a radio is operating at very high channel utilization. What should the administrator investigate first?

1. DNS records
2. RADIUS accounting
3. DHCP lease duration
4. RF interference and channel congestion

Correct Answer: 4

Explanation

High RF channel utilization indicates that significant wireless airtime is being consumed. The administrator should investigate sources of congestion, including neighboring access points, client traffic, non-Wi-Fi interference, and potentially unsuitable channel assignments. DNS records, RADIUS accounting, and DHCP lease duration do not directly explain excessive radio channel utilization. Aruba wireless management tools can provide RF information that helps identify congested channels and interference sources. Based on those measurements, the administrator can determine whether radio configuration or channel planning needs adjustment. Therefore, RF interference and channel congestion should be investigated first.

Question 26

Which protocol allows an Aruba network device to synchronize its clock with a centralized time source?

1. SNMP
2. NTP
3. RADIUS
4. Syslog

Correct Answer: 2

Explanation

Network Time Protocol, or NTP, allows network devices to synchronize their clocks with a reliable time source. Accurate time is important for event logging, troubleshooting, authentication, certificate validation, and security monitoring. SNMP is mainly used for device monitoring and management, RADIUS provides centralized authentication and authorization, and Syslog transports event messages to logging systems. When multiple Aruba devices use a common NTP source, their timestamps can be correlated more accurately during troubleshooting or security investigations. Therefore, NTP is the correct protocol for maintaining consistent system time.

Question 27

An administrator wants to monitor CPU utilization and interface statistics from Aruba network devices using a network management platform. Which protocol is most appropriate?

1. FTP
2. NTP
3. SNMP
4. SMTP

Correct Answer: 3

Explanation

SNMP is widely used for collecting operational information from network devices. A network management platform can use SNMP to retrieve metrics such as CPU utilization, memory usage, interface counters, and device status. This information can be used to create dashboards, monitor trends, and generate alerts when thresholds are exceeded. FTP is intended for file transfers, NTP provides time synchronization, and SMTP is used for email transport. Therefore, SNMP is the appropriate protocol for centralized monitoring of Aruba device performance and interface statistics.

Question 28

An administrator needs to provide employees with secure enterprise wireless authentication using individual credentials rather than one shared wireless password. Which option should be used?

1. WPA2-Enterprise with 802.1X
2. Open authentication
3. WPA2-Personal
4. MAC filtering only

Correct Answer: 1

Explanation

WPA2-Enterprise with 802.1X provides individual authentication for wireless users and commonly integrates with a RADIUS authentication server. Each user can authenticate with their own credentials rather than sharing one pre-shared key. This provides centralized identity management and allows network policies to be applied based on authentication information. WPA2-Personal uses a shared pre-shared key, while open authentication provides no meaningful wireless authentication. MAC filtering can restrict devices based on hardware addresses but does not provide the same user-centric authentication model. Therefore, WPA2-Enterprise with 802.1X is appropriate for enterprise wireless access.

Question 29

A wireless administrator wants to encourage compatible clients to connect to 5 GHz instead of 2.4 GHz when appropriate. Which Aruba feature should be considered?

1. DHCP relay
2. ARP inspection
3. Static routing
4. Band steering

Correct Answer: 4

Explanation

Band steering can encourage capable wireless clients to associate with a preferred frequency band. In many environments, administrators use it to encourage compatible clients toward 5 GHz, which may offer additional channels and reduced congestion compared with 2.4 GHz. Actual results depend on client capabilities, RF conditions, and network configuration. DHCP relay forwards DHCP traffic between network segments, ARP inspection provides security controls related to ARP behavior, and static routing defines fixed Layer 3 paths. Therefore, band steering is the Aruba wireless feature relevant to influencing clients toward a preferred frequency band.

Question 30

An administrator wants to send Aruba device event messages to a centralized logging server for troubleshooting and auditing. Which protocol should be configured?

1. RADIUS
2. DHCP
3. Syslog
4. ICMP

Correct Answer: 3

Explanation

Syslog is commonly used to transmit system and event messages from network devices to a centralized logging server. Centralized logs allow administrators to review device events, troubleshoot failures, correlate activity across multiple devices, and support auditing requirements. RADIUS is primarily associated with authentication and authorization, DHCP provides IP configuration, and ICMP is used for network diagnostic and control messages. Aruba devices can be configured to generate and forward relevant logging information to centralized systems. Therefore, Syslog is the appropriate protocol when an administrator needs centralized collection of network-device event messages.

Question 31

A wireless client receives an IP address but cannot communicate with devices outside its local subnet. Which client configuration should be checked?

1. Default gateway
2. SSID broadcast interval
3. Radio transmit power
4. Channel width

Correct Answer: 1

Explanation

The default gateway provides the Layer 3 path from a client to destinations outside its local IP subnet. A client can successfully associate with an access point and receive an IP address but still fail to reach remote networks if the default gateway is missing or incorrect. SSID broadcast behavior and radio transmit power affect wireless discovery and RF performance, while channel width affects available wireless bandwidth. These settings do not normally provide the routing path to another IP subnet. Therefore, the administrator should first verify the client’s IP configuration, especially its default gateway.

Question 32

An Aruba administrator wants to securely manage a switch remotely through a command-line interface. Which protocol should be used?

1. Telnet
2. SSH
3. FTP
4. HTTP

Correct Answer: 2

Explanation

SSH provides encrypted remote command-line management and protects authentication credentials and session data while they travel across the network. It is preferred over Telnet because Telnet transmits information without the same level of encryption. FTP is designed for file transfers, while HTTP is generally used for web-based communication. Secure management should also be restricted to trusted administrative networks and protected with appropriate authentication controls. Therefore, SSH is the appropriate protocol when an Aruba administrator needs encrypted remote CLI access to a network device.

Question 33

An administrator wants wireless clients to automatically receive an IP address, subnet mask, default gateway, and DNS server information. Which service provides these parameters?

1. SNMP
2. RADIUS
3. DHCP
4. Syslog

Correct Answer: 3

Explanation

DHCP automatically provides network configuration information to clients. A DHCP response can include an IP address, subnet mask, default gateway, DNS server addresses, lease information, and other supported options. This simplifies client deployment because administrators do not need to manually configure every device. SNMP is used for monitoring and management, RADIUS provides authentication and authorization, and Syslog is used for centralized event logging. Therefore, DHCP is the correct service when wireless clients need automatic network addressing and related configuration parameters.

Question 34

An administrator needs to determine whether an Aruba switch interface is experiencing packet errors or drops. Which information should be reviewed?

1. DNS records
2. NTP peers
3. RADIUS attributes
4. Interface counters

Correct Answer: 4

Explanation

Interface counters provide detailed information about traffic and errors on a network interface. Administrators can examine received and transmitted packets, errors, discarded packets, collisions where applicable, and other interface statistics. These counters can help identify physical-layer problems, congestion, duplex issues, or other connectivity conditions. DNS records provide name-resolution information, NTP peers relate to time synchronization, and RADIUS attributes are associated with authentication and authorization. Therefore, interface counters are the most useful information for determining whether a switch interface is experiencing packet errors or drops.

Question 35

An Aruba administrator wants to provide different network access privileges to employees and contractors after successful authentication. Which capability should be configured?

1. Role-based access control
2. RF channel selection
3. NTP synchronization
4. DHCP reservation

Correct Answer: 1

Explanation

Role-based access control allows network policies to be applied according to the role assigned to an authenticated user or device. Employees and contractors can therefore receive different access permissions even when they use the same physical network infrastructure. Roles can control access to internal resources, Internet destinations, applications, and other network services. RF channel selection affects wireless radio operation, NTP provides time synchronization, and DHCP reservations associate addresses with specific clients. Therefore, role-based access control is the appropriate capability for providing differentiated network privileges based on user roles.

Question 36

A network administrator needs to configure an authentication server for Aruba 802.1X wireless access. Which protocol is commonly used between the Aruba infrastructure and the authentication server?

1. FTP
2. RADIUS
3. NTP
4. DNS

Correct Answer: 2

Explanation

RADIUS is commonly used between Aruba network infrastructure and an authentication server for 802.1X-based access. It supports authentication, authorization, and accounting and can work with enterprise wireless security mechanisms. When a client attempts to authenticate, the network infrastructure can forward authentication information to the RADIUS server, which validates the user’s credentials and returns an authorization result. FTP handles file transfers, NTP synchronizes clocks, and DNS provides name resolution. Therefore, RADIUS is the appropriate protocol for integrating Aruba 802.1X access with a centralized authentication server.

Question 37

An administrator needs to separate two groups of wireless users by assigning each group to a different Layer 2 network. Which configuration is most appropriate?

1. Increase radio transmit power
2. Enable NTP
3. Map different SSIDs to different VLANs
4. Configure additional DNS records

Correct Answer: 3

Explanation

Mapping different SSIDs to different VLANs provides logical Layer 2 separation between wireless user groups. For example, a corporate SSID can map users to a corporate VLAN while a guest SSID maps users to a guest VLAN. Additional access-control policies can then determine what resources each VLAN can reach. Increasing radio transmit power does not provide logical segmentation, NTP handles time synchronization, and DNS records provide name-resolution information. Therefore, mapping separate SSIDs to appropriate VLANs is a suitable approach for separating wireless user groups at Layer 2.

Question 38

A wireless administrator needs to investigate whether neighboring access points are contributing to interference on a particular channel. Which information should be examined?

1. DHCP lease table
2. RADIUS accounting records
3. DNS cache
4. RF neighbor and interference information

Correct Answer: 4

Explanation

RF neighbor and interference information can help administrators identify nearby wireless transmitters and determine whether they may be contributing to channel contention or interference. Examining the surrounding RF environment is important when diagnosing poor wireless performance, especially in environments with many access points. DHCP lease tables provide IP address assignment information, RADIUS accounting records provide authentication-related activity, and DNS caches contain name-resolution information. These sources do not directly describe the RF environment. Therefore, RF neighbor and interference information should be examined when investigating nearby wireless sources.

Question 39

An administrator wants to restrict access to a wireless network so that only devices with approved hardware addresses can connect. Which mechanism can provide this type of filtering?

1. MAC authentication
2. NTP
3. SNMP
4. Syslog

Correct Answer: 1

Explanation

MAC authentication can use a client’s MAC address as part of the network access decision. An Aruba administrator can maintain an authorized list or integrate MAC-based authentication with an external authentication system, depending on the deployment. This approach can provide a basic device-based access control mechanism, although MAC addresses can potentially be spoofed and should not be considered a strong standalone security control for sensitive environments. NTP provides time synchronization, SNMP provides monitoring, and Syslog provides event logging. Therefore, MAC authentication is the mechanism most directly associated with filtering access based on device MAC addresses.

Question 40

An Aruba administrator wants to verify whether a network device is reachable over the IP network before troubleshooting higher-level services. Which protocol or utility is commonly used?

1. FTP
2. RADIUS
3. NTP
4. ICMP

Correct Answer: 4

Explanation

ICMP is commonly used by diagnostic utilities such as ping to test IP-level reachability between network devices. A successful ICMP response can indicate that a device is reachable and responding at the network layer, although it does not guarantee that higher-level services are functioning. FTP is used for file transfers, RADIUS handles authentication and authorization, and NTP provides time synchronization. Therefore, ICMP is an appropriate first-level diagnostic mechanism when an administrator wants to determine whether a network device is reachable over IP before investigating application or service-specific problems.
