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
A
Explanation:
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.

- 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
B
Explanation:
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

- C . ip route 0.0 0 0/0 10.4.5.1
- D . default-gateway 10.4.5.1
C
Explanation:
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:

What Is the ideal access switch for this large hospital with distribution racks of over 400 ports in a single VSF stack?
- A . OCX 6300
- B . OCX 6400
- C . OCX 6200
- D . OCX 6100
A
Explanation:
The ideal access switch for a large hospital with distribution racks of over 400 ports in a single VSF stack is the CX 6300.
This switch provides the following benefits:
– The CX 6300 supports up to 48 ports per switch and up to 10 switches per VSF stack, allowing for a total of 480 ports in a single stack. This meets the requirement of having over 400 ports in a single VSF stack.
– The CX 6300 supports high-performance switching with up to 960 Gbps of switching capacity and up to 714 Mpps of forwarding rate. This meets the requirement of having high throughput and low latency for mobile equipment and patient data.
– The CX 6300 supports advanced features such as dynamic segmentation, policy-based routing, and role-based access control. These features enhance the security and flexibility of the network by applying different policies and roles to different types of devices and users.
– The CX 6300 supports Aruba NetEdit, a network configuration and orchestration tool that simplifies the management and automation of the network. This reduces the complexity and human errors involved in network configuration and maintenance.
The other options are not ideal because:
– OCX 6400: This switch is designed for data center applications and does not support VSF stacking. It also does not support dynamic segmentation or policy-based routing, which are useful for network security and flexibility.
– OCX 6200: This switch is designed for small to medium-sized businesses and does not support VSF stacking. It also has lower switching capacity and forwarding rate than the CX 6300, which may affect the performance of the network.

Based on the "snow ip route" output on an AruDaCX 8400. what type of route is "10.1 20 0/24, vrf default via 10.1.12.2. [1/0]"?
- A . local
- B . static
- C . OSPF
- D . connected
B
Explanation:
A static route is a route that is manually configured on a router or switch and does not change unless it is modified by an administrator. Static routes are used to specify how traffic should reach specific destinations that are not directly connected to the device or that are not reachable by dynamic routing protocols. In Aruba CX switches, static routes can be configured using the ip route command in global configuration mode. Based on the “show ip route” output on an Aruba CX 8400 switch, the route “10.1 20 0/24, vrf default via 10.1.12.2, [1/0]” is a static route because it has an administrative distance of 1 and a metric of 0, which are typical values for static routes.

What is an advantage of using Layer 2 MAC authentication?
- A . it matches user names to MAC address
- B . No setup is required on the client
- C . MAC allow lists are easily maintained over time
- D . MAC identifiers are hard to spoof
B
Explanation:
Layer 2 MAC authentication is a method of authenticating devices based on their MAC addresses without requiring any client-side configuration or credentials. The switch sends the MAC address of the device to an authentication server such as ClearPass or RADIUS, which checks if the MAC address is authorized to access the network. If yes, the switch grants access to the device based on the assigned role and policies. If no, the switch denies access or redirects the device to a captive portal for further authentication.

- C . The Core is connected to the incorrect physical interlaces
- D . LACP is not configured on the Core uplink
D
Explanation:
LACP is a protocol that allows multiple physical links to be aggregated into a single logical link for increased bandwidth and redundancy. LACP must be configured on both ends of the link for it to work properly. In this case, EDGE1 has LACP configured on its uplink port-channel 1, but CORE1 does not have LACP configured on its corresponding port-channel 1. This causes a mismatch and prevents the link from coming up.

You need to drop excessive broadcast traffic on ingress to an ArubaOS-CX switch.
What is the best technology to use for this task?
- A . Rate limiting
- B . DWRR queuing
- C . QoS shaping
- D . Strict queuing
A
Explanation:
The best technology to use for dropping excessive broadcast traffic on ingress to an ArubaOS-CX switch is rate limiting. Rate limiting is a feature that allows network administrators to control the amount of traffic that enters or leaves a port or a VLAN on a switch by setting bandwidth thresholds or limits. Rate limiting can be used to prevent network congestion, improve network performance, enforce service level agreements(SLAs), or mitigate denial-of-service (DoS) attacks. Rate limiting can be applied to broadcast traffic on ingress to an ArubaOS-CX switch by using the storm-control command in interface configuration mode. This command allows network administrators to specify the percentage of bandwidth or packets per second that can be used by broadcast traffic on an ingress port. If the broadcast traffic exceeds the specified threshold, the switch will drop the excess packets.
The other options are not technologies for dropping excessive broadcast traffic on ingress because:
– DWRR queuing: DWRR stands for Deficit Weighted Round Robin, which is a queuing algorithm that assigns different weights or priorities to different traffic classes or queues on an egress port. DWRR ensures that each queue gets its fair share of bandwidth based on its weight while avoiding starvation of lower priority queues. DWRR does not drop excessive broadcast traffic on ingress, but rather schedules outgoing traffic on egress.
– QoS shaping: QoS stands for Quality of Service, which is a set of techniques that manage network resources and provide different levels of service to different types of traffic based on their requirements. QoS shaping is a technique that delays or buffers outgoing traffic on an egress port to match the available bandwidth or rate limit. QoS shaping does not drop excessive broadcast traffic on ingress, but rather smooths outgoing traffic on egress.
– Strict queuing: Strict queuing is another queuing algorithm that assigns different priorities to different traffic classes or queues on an egress port. Strict queuing ensures that higher priority queues are always served before lower priority queues regardless of their bandwidth requirements or weights. Strict queuing does not drop excessive broadcast traffic on ingress, but rather schedules outgoing traffic on egress.

Where are wireless client roaming decisions made?
- A . Client device
- B . Virtual Controller
- C . Joint decision made by the origination and destination APs
- D . Aruba Central
A
Explanation:
Wireless client roaming decisions are made by the client device based on its own criteria, such as signal strength, noise level, data rate, etc. The network can influence the client’s roaming decision by providing information such as neighbor reports, load balancing, band steering, etc., but the final decision is up to the client.

In which subnet will the client IPs reside?
- A . The same subnet as the mobility controller
- B . The same subnet as the Aruba ESP gateway
- C . The same subnet as the mobility conductor
- D . The same subnet as the access point
D
Explanation:
When using an Aruba standalone AP, selecting “Native VLAN” for the Client VLAN Assignment means that the clients will get their IP addresses from the same subnet as the access point’s IP address. This is because the access point acts as a DHCP server for the clients in this mode.

You are configuring a network with a stacked pair of 6300M switches used for distribution and layer 3 services. You create a new VLAN for users that will be used on multiple access stacks of CX6200 switches connected downstream of the distribution stack You will be creating multiple VLANs/subnets similar to this will be utilized in multiple access stacks
What is the correct way to configure the routable interface for the subnet to be associated with this VLAN?
- A . Create a physically routed interface in the subnet on the 6300M stack for each downstream switch.
- B . Create an SVl in the subnet on each downstream switch
- C . Create an SVl in the subnet on the 6300M stack, and assign the management address of each downstream switch stack to a different IP address in the same subnet
- D . Create an SVl in the subnet on the 6300M stack.
D
Explanation:
The correct way to configure the routable interface for the subnet to be associated with this VLAN is to create an SVI Switched Virtual Interface (SVI) Switched Virtual Interface (SVI) is a virtual interface on a switch that represents a VLAN and provides Layer 3 routing functions for that VLAN. SVIs are used to enable inter-VLAN routing, provide gateway addresses for hosts in VLANs, apply ACLs or QoS policies to VLANs, etc. SVIs have some advantages over physical routed interfaces such as saving interface ports, reducing cable costs, simplifying network design, etc. SVIs are usually numbered according to their VLAN IDs (e.g., vlan 10) and assigned IP addresses within the subnet of their VLANs. SVIs can be created and configured by using commands such as interface vlan, ip address, no shutdown, etc. SVIs can be verified by using commands such as show ip interface brief, show vlan, show ip route, etc. in the subnet on the 6300M stack. An SVI is a virtual interface on a switch that represents a VLAN and provides Layer 3 routing functions for that VLAN. Creating an SVI in the subnet on the 6300M stack allows the switch to act as a gateway for the users in that VLAN and enable inter-VLAN routing between different subnets. Creating an SVI in the subnet on the 6300M stack also simplifies network design and management by reducing the number of physical interfaces and cables required for routing.
The other options are not correct ways to configure the routable interface for the subnet to be associated with this VLAN because:
– Create a physically routed interface in the subnet on the 6300M stack for each downstream switch: This option is incorrect because creating a physically routedinterface in the subnet on the 6300M stack for each downstream switch would require using one physical port and cable per downstream switch, which would consume interface resources and increase cable costs. Creating a physically routed interface in the subnet on the 6300M stack for each downstream switch would also complicate network design and management by requiring separate routing configurations and policies for each interface.
– Create an SVl in the subnet on each downstream switch: This option is incorrect because creating an SVI in the subnet on each downstream switch would not enable inter-VLAN routing between different subnets, as each downstream switch would act as a gateway for its own VLAN only. Creating an SVI in the subnet on each downstream switch would also create duplicate IP addresses in the same subnet, which would cause IP conflicts and routing errors.
– Create an SVl in the subnet on the 6300M stack, and assign the management address of each downstream switch stack to a different IP address in the same subnet: This option is incorrect because creating an SVI in the subnet on the 6300M stack, and assigning the management address of each downstream switch stack to a different IP address in the same subnet would not enable inter-VLAN routing between different subnets, as each downstream switch would still act as a gateway for its own VLAN only. Creating an SVI in the subnet on the 6300M stack, and assigning the management address of each downstream switch stack to a different IP address in the same subnet would also create unnecessary IP addresses in the same subnet, which would waste IP space and complicate network management.

Refer to the exhibit.
In the given topology, a pair of Aruba CX 8325 switches are in a VSX stack using the active gateway.
What is the nature and behavior of the Virtual IP for the VSX pair if clients are connected to the access switch using VSX as the default gateway?
- A . Virtual IP is active on the primary VSX switch
- B . Virtual floating IP will failover in case of a failure
- C . Virtual IP is active on both CX switches
- D . Virtual IP uses SVI IP address synced with VSX
A
Explanation:
Virtual Switching Extension (VSX) is a feature that allows two Aruba CX switches to operate as a single logical device with a single control plane and data plane. VSX provides high availability, scalability, and simplified management for campus and data center networks3. In VSX, one switch is designated as the primary switch and the other as the secondary switch. The primary switch owns and responds to ARP Address Resolution Protocol. ARP is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite. requests for the virtual IP address of the VSX pair4. The virtual IP address is used as the default gateway for clients connected to the access switch. If the primary switch fails, the secondary switch takes over the virtual IP address and continues to forward traffic for the clients5.

What are the main characteristics of the 6 GHz band?
- A . Less RF signal is absorb by objects in a 6 GHz WLAN.
- B . In North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the 5 GHz band.
- C . The 6 GHz band is fully backward compatible with the existing bands.
- D . Low Power Devices are allowed for indoor and outdoor usage.
B
Explanation:
The main characteristic of the 6 GHz band that is true among the given options is that in North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the 5 GHz band. This characteristic provides more spectrum availability, less interference, and higher throughput for wireless devices that support Wi-Fi 6E Wi-Fi Enhanced (Wi-Fi 6E) is an extension of Wi-Fi 6 (802.11ax) standard that operates in the newly available unlicensed frequency spectrum around 6 GHz in addition to existing bands below it.
Some facts about this characteristic are:
– In North America, there are up to seven non-overlapping channels available in each of three channel widths (20 MHz, 40 MHz, and 80 MHz) in the entire unlicensed portion of the new spectrum (5925C7125 MHz). This means there are up to 21 non-overlapping channels available for Wi-Fi devices in total.
– In comparison, in North America, there are only nine non-overlapping channels available in each of two channel widths (20 MHz and 40 MHz) in the entire unlicensed portion of the existing spectrum below it (2400C2483 MHz and 5150C5825 MHz). This means there are only up to nine non-overlapping channels available for Wi-Fi devices in total.
– Therefore, in North America, there are more than twice as many non-overlapping channels available in each channel width in the new spectrum than in the existing spectrum below it.
– Specifically, there are more than twice as many non-overlapping channels available at 80 MHz width (seven) than at 40 MHz width (three) in the existing spectrum below it.
The other options are not true because:
– Less RF signal is absorbed by objects in a 6 GHz WLAN: This option is false because higher frequency signals tend to be more absorbed by objects than lower frequency signals due to higher attenuation Attenuation is a general term that refers to any reduction in signal strength during transmission over distance or through an object or medium. Therefore, RF signals in a 6 GHz WLAN would be more absorbed by objects than RF signals in a lower frequency WLAN.
– The 6 GHz band is fully backward compatible with existing bands: This option is false because Wi-Fi devices need to support Wi-Fi 6E standard to operate in the new spectrum around 6 GHz. Existing Wi-Fi devices that do not support Wi-Fi 6Estandard cannot use this spectrum and can only operate in existing bands below it.
– Low Power Devices are allowed for indoor and outdoor usage: This option is false because Low Power Indoor Devices (LPI) are only allowed for indoor usage under certain power limits and registration requirements. Outdoor usage of LPI devices is prohibited by regulatory authorities such as FCC Federal Communications Commission (FCC) is an independent agency of United States government that regulates communications by radio, television, wire, satellite, and cable across United States. However, outdoor usage of Very Low Power Devices (VLP) may be allowed under certain power limits and without registration requirements.

Match the phase of message processing with the Open Systems interconnection (OSl) layer.
Explanation:
In the OSI model, data is handled differently at each layer. Here is the correct matching of the phase of message processing with the OSI layer:
Physical Layer: Organizes the data into bits.
Data Link Layer: Organizes the data into frames.
Network Layer: Organizes the data into packets.
Transport Layer: Organizes the data into segments.
The Physical Layer is responsible for the transmission of raw bits over a physical medium. The Data Link Layer encapsulates packets into frames with MAC addresses for node-to-node communication. The Network Layer is responsible for packet forwarding including routing through intermediate routers. The Transport Layer provides reliable data transfer services to the upper layers and handles the segmentation and reassembly of data.
When measuring signal strength, dBm is commonly used and 0 dBm corresponds to 1 mW power.
What does -20 dBm correspond to?
- A . .-1 mW
- B . .01 mw
- C . 10 mW
- D . 1mW
B
Explanation:
dBm is a unit of power that measures the ratio of a given power level to 1 mW. The formula to convert dBm to mW is: P(mW) = 1mW * 10^(P(dBm)/10). Therefore, -20 dBm corresponds to 0.01 mW, as follows: P(mW) = 1mW * 10^(-20/10) = 0.01 mW
