- A . ip-route 10.2.10.0/24 172.16.1.1
- B . ip route 10.2.10.0.255.255.255.0 172.16.1.1 description aruba
- C . ip route 10.2.10.0/22.214.171.124
- D . ip route-static 10.2 10.0.255.255.255.0 172.16.1.1
The correct command to add a static route to a class-c-network 10.2.10.0 via a gateway of 172.16.1.1 is ip-route 10.2.10.0/24 172.16.1.1. This command specifies the destination network address (10.2.10.0) and prefix length (/24) and the next-hop address (172.16.1 .1) for reaching that network from the switch. The other commands are either incorrect syntax or incorrect parameters for adding a static route.
When would you bond multiple 20MHz wide 802.11 channels?
- A . To decrease the Signal to Noise Ratio (SNR)
- B . To increase throughput between the client and AP
- C . To provision highly available AP groups
- D . To utilize high gain omni-directional antennas
Bonding multiple 20MHz wide 802.11 channels is a technique to create a wider bandwidth channel that supports higher data rate transmissions. It can increase the throughput between the client and AP by using more spectrum resources and reducing interference.
What is indicated by a solid amber radio status LED on an Aruba AP?
- A . Not enough PoE is provided from the switch to power both radios of the AP
- B . The radio is working in mesh mode
- C . The radio is working the 5 GHz band only.
- D . The radio is enabled in monitor or spectrum analysis mode
On an Aruba AP, a solid amber radio status LED indicates: A. Not enough PoE is provided from the switch to power both radios of the AP
When the radio status LED on an Aruba AP shows a solid amber color, it typically signifies that the PoE (Power over Ethernet) supplied by the switch is insufficient to power both radios of the AP (usually the 2.4 GHz and 5 GHz bands). This may require checking the PoE budget of the switch or using a higher-powered PoE source.
Other options, such as the radio working in mesh mode, operating only in the 5 GHz band, or being enabled in monitor or spectrum analysis mode, typically do not result in the LED showing a solid amber color.
What does WPA3-Personal use as the source to generate a different Pairwise Master Key (PMK) each time a station connects to the wireless network?
- A . Session-specific information (MACs and nonces)
- B . Opportunistic Wireless Encryption (OWE)
- C . Simultaneous Authentication of Equals (SAE)
- D . Key Encryption Key (KEK)
Which flew in a Layer 3 IPv4 packet header is used to mitigate Layer 3 route loops?
- A . Checksum
- B . Time To Live
- C . Protocol
- D . Destination IP
The field in a Layer 3 IPv4 packet header that is used to mitigate Layer 3 route loops is Time To Live (TTL). TTL is an 8-bit field that indicates the maximum number of hops that a packet can traverse before being discarded. TTL is set by the source device and decremented by one by each router that forwards the packet. If TTL reaches zero, the packet is dropped and an ICMP Internet Control Message Protocol (ICMP) Internet Control Message Protocol (ICMP) is a network protocol that provides error reporting and diagnostic functions for IP networks. ICMP is used to send messages such as echo requests and replies (ping), destination unreachable, time exceeded, parameter problem, source quench, redirect, etc. ICMP messages are encapsulated in IP datagrams and have a specific format that contains fields such as type, code, checksum, identifier, sequence number, data, etc. ICMP messages can be verified by using commands such as ping,
traceroute, debug ip icmp, etc. message is sent back to the source device. TTL is used to mitigate Layer 3 route loops because it prevents packets from circulating indefinitely in a looped network topology. TTL also helps to conserve network resources and avoid congestion caused by looped packets.
The other options are not fields in a Layer 3 IPv4 packet header because:
– Checksum: Checksum is a 16-bit field that is used to verify the integrity of the IP header. Checksum is calculated by the source device and verified by the destination device based on the values of all fields in the IP header. Checksum does not mitigate Layer 3 route loops because it does not limit the number of hops that a packet can traverse.
– Protocol: Protocol is an 8-bit field that indicates the type of payload carried by the IP datagram. Protocol identifies the upper-layer protocol that uses IP for data transmission, such as TCP Transmission Control Protocol (TCP) Transmission Control Protocol (TCP) is a connection-oriented transport layer protocol that provides reliable, ordered, and error-checked delivery of data between applications on different devices. TCP uses a three-way handshake to establish a connection between two endpoints, and uses sequence numbers, acknowledgments, and windowing to ensure data delivery and flow control. TCP also uses mechanisms such as retransmission, congestion avoidance, and fast recovery to handle packet loss and congestion. TCP segments data into smaller units called segments, which are encapsulated in IP datagrams and have a specific format that contains fields such as source port, destination port, sequence number, acknowledgment number, header length, flags, window size, checksum, urgent pointer, options, data, etc. TCP segments can be verified by using commands such as telnet, ftp, ssh, debug ip tcp transactions, etc ., UDP User Datagram Protocol (UDP) User Datagram Protocol (UDP) is a connectionless transport layer protocol that provides
A network administrator with existing IAP-315 access points is interested in Aruba Central and needs to know which license is required for specific features Please match the required license per feature (Matches may be used more than once.)
a) Alerts on config changes via email – Foundation
b) Group-based firmware compliance – Foundation
c) Heat maps of deployed APs – Advanced
d) Live upgrades of an AOS10 cluster – Advanced
According to the Aruba Central Licensing Guide1, the Foundation License provides basic device management features such as configuration, monitoring, alerts, reports, firmware management, etc. The Advanced License provides additional features such as AI insights, WLAN services, NetConductor Fabric, heat maps, live upgrades, etc.
A network technician is troubleshooting one new AP at a branch office that will not receive Its configuration from Aruba Central. The other APs at the branch are working as expected. The output of the ‘show ap debug cloud-server command’ shows that the "cloud conflg received" Is FALSE.
After confirming the new AP has internet access, what would you check next?
- A . Disable and enable activate to trigger provisioning refresh
- B . Verify the AP can ping the device on arubanetworks.com
- C . Verify the AP has a license assigned
- D . Disable and enable Aruba Central to trigger configuration refresh
If the AP has internet access but does not receive its configuration from Aruba Central, one possible reason is that the AP does not have a license assigned in Aruba Central. A license is required for each AP to be managed by Aruba Central.
A network technician is using Aruba Central to troubleshoot network issues.
Which dashboard can be used to view and acknowledge issues when beginning the troubleshooting process?
- A . the Alerts and Events dashboard
- B . the Audit Trail dashboard
- C . the Reports dashboard
- D . the Tools dashboard
The Alerts and Events dashboard displays all types of alerts and events generated for events pertaining to device provisioning, configuration, and user management. You can use the Config icon to configure alerts and notifications for different alert categories and severities1. You can also view the alerts and events in the List view and Summary view2.
You need to configure wireless access for several classes of loT devices, some of which operate only with 802 11b. Each class must have a unique PSK and will require a different security policy applied as a role There will be 15-20 different classes of devices and performance should be optimized
Which option fulfills these requirements?
- A . Single SSID with MPSK for each loT class using 5 GHz and 6 GHz bands
- B . Single SSID with MPSK for each loT class using 2.4GHz and 5 GHz bands
- C . Individual SSIDs with unique PSK for each loT class, using 5GHz and 6 GHz bands

Which commands are used to set a default route to 10.4.5.1 on an Aruba CX switch when ln-band management using an SVl is being used?
- A . iP default-gateway 10.4.5.1
- B . ip route 0 0 0.070 10.4 5.1 vrf mgmt
- C . ip route 0.0 0 0/0 10.4.5.1
- D . default-gateway 10.4.5.1
The command that is used to set a default route to 10.4.5.1 on an Aruba CX switch when in-band management using an SVI is being used is ip route 0.0 0 0/0 10.4.5.1. This command specifies the destination network address (0.0 0 0) and prefix length (/0) and the next-hop address (10.4.5.1) for reaching any network that is not directly connected to the switch. The default route applies to the default VRF Virtual Routing and Forwarding. VRF is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. VRFs are typically used to segment network traffic for security, privacy, or administrative purposes., which is used for in-band management traffic that goes through an SVI Switch Virtual Interface. SVI is a virtual interface on a switch that allows the switch to route packets between different VLANs on the same switch or different switches that are connected by a trunk link. An SVI is associated with a VLAN and has an IP address and subnet mask assigned to it12. References:
