What is enabled by LLDP-MED? (Select two.)

• A. Voice VLANs can be automatically configured for VoIP phones
• B. APs can request power as needed from PoE-enabled switch ports
• C. GVRP VLAN information can be used to dynamically add VLANs to a trunk
• D. iSCSl client devices can set the required MTU setting for the port.
• E. iSCSl client devices can request to have flow control enabled

Answer: A,B

Explanation:
Explanation
These are two benefits enabled by LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery).
LLDP-MED is an extension of LLDP that provides additional capabilities for network devices such as VoIP phones and APs. One of the capabilities is to automatically configure voice VLANs for VoIP phones, which allows them to be placed in a separate VLAN from data devices and receive QoS and security policies.
Another capability is to request power as needed from PoE-enabled switch ports, which allows APs to adjust their power consumption and performance based on the available power budget. The other options are incorrect because they are either not enabled by LLDP-MED or not related to LLDP-MED. References:

NEW QUESTION # 26
A customer has a large number of food-producing machines
* All machines are connected via Aruba CX6200 switches in VLANs 100.110. and 120
* Several external technicians are maintaining this special equipment
What are the correct commands to ensure that no rogue DHCP server will impact the network?

• A.
• B.
• C.
• D.

Answer: A

Explanation:
Explanation
configures DHCP snooping on the switch and enables it for VLANs 100, 110, and 120. It also specifies the IP address of the authorized DHCP server and sets the ports connected to the server as trusted. This prevents any unauthorized DHCP server from providing invalid configuration data to the clients on those VLANs. Option B also enables DHCP option-82, which adds information about the switch port and VLAN to the DHCP packets, allowing for more granular control and logging of DHCP transactions.

NEW QUESTION # 27
For the Aruba CX 6400 switch, what does virtual output queueing (VOQ) implement that is different from most typical campus switches?

• A. VSX
• B. large egress packet buffers
• C. per port ASICs
• D. large ingress packet buffers

Answer: D

Explanation:
Explanation
The Aruba CX 6400 switch is a modular switch that supports high-performance and high-density Ethernet switching for campus and data center networks. One of the features that distinguishes the Aruba CX 6400 switch from most typical campus switches is virtual output queueing (VOQ). VOQ is a technique that implements large ingress packet buffers on each port to prevent head-of-line blocking and packet loss due to congestion2. VOQ allows each port to have multiple queues for different output ports and prioritize packets based on their destination and QoS class2. VOQ enables the Aruba CX 6400 switch to achieve high throughput and low latency for various traffic types and scenarios. References: 2

NEW QUESTION # 28
With the Aruba CX 6000 24G switch with uplinks of 1/1/25 and what does the switch do when a client port detects a loop and the do-not-disabie parameter is used?

• A. Port status led blinks in amber with 100hz.
• B. An event log message is created.
• C. Port status will be validated once status is cleared
• D. The network analytics engine is triggered.

Answer: B

Explanation:
Explanation
The correct answer is B. An event log message is created.
The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured1.
The other options are incorrect because:
A: Port status will not be validated once status is cleared. The port will remain enabled even if a loop is detected, unless the loop-protect action is changed to tx-disable or tx-rx-disable1.
C: The network analytics engine will not be triggered by a loop detection. The network analytics engine is a feature that allows users to monitor and troubleshoot network issues using scripts and agents2.
D: Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port status, such as link speed and activity, regardless of the loop detection3.

NEW QUESTION # 29
When configuring UBT on a switch what will happen when a gateway role is not specified?

• A. The switch will put the client on the access VLAN
• B. The gateway will send back the deny role to the client.
• C. The gateway will assign a default role to the client
• D. The switch will assign the default deny role to the client.

Answer: A

Explanation:
According to the Aruba Documentation Portal1, user-based tunneling (UBT) is a feature that uses GRE to tunnel ingress traffic on a switch interface to a gateway for further processing. UBT enables a switch to provide a centralized security policy, using per-user authentication and access control to ensure consistent access and permissions.
Option A: The switch will put the client on the access VLAN
This is because option A shows how UBT works on an Aruba switch. When a device connects to the network, it is authenticated using either MAC Authentication or 802.1X and triggers an enforcement policy from ClearPass, which contains an enforcement profile with a user role configuration. The user role can be assigned locally on the switch or on ClearPass as part of an enforcement profile. The user role determines the VLAN that the device belongs to and the access policies that apply to it23.
Therefore, option A is correct.

NEW QUESTION # 30
Your Aruba CX 6300 VSF stack has OSPF adjacency over SVI 10 with LAG 1 to a neighboring device The following configuration was created on the switch:

• A.
• B.
• C.
• D.

Answer: C

Explanation:
Explanation
The correct configuration for OSPF adjacency over SVI 10 with LAG 1 to a neighboring device is shown in Option C. The configuration includes the following steps:
* Create a VLAN 10 and assign it a name and an IP address.
* Create a LAG 1 and assign it a name and a mode of dynamic or static.
* Add member ports to LAG 1 and enable the LAG interface.
* Assign VLAN 10 as the untagged VLAN for LAG 1.
* Enable OSPF on the switch and assign it a router ID.
* Create an OSPF area 0 and add SVI 10 as an interface in that area.
Option A is incorrect because it does not enable OSPF on the switch or create an OSPF area. Option B is incorrect because it assigns VLAN 10 as the tagged VLAN for LAG 1, which is not compatible with SVI 10.
Option D is incorrect because it does not add member ports to LAG 1 or enable the LAG interface.

NEW QUESTION # 32
What is a primary benefit of BSS coloring?

• A. BSS color tags improve security by identifying rogue APS and tagging them as threats.
• B. BSS color tags improve performance by allowing APS on the same channel to be farther apart
• C. BSS color tags are applied to WI-Fi channels and can reduce the threshold tor interference
• D. BSS color tags are applied on the wireless controllers and can reduce the threshold for interference_

Answer: C

Explanation:
Explanation
The primary benefit of BSS coloring is D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference.
BSS coloring is a mechanism that allows Wi-Fi 6 devices to mark each frame with a color code that identifies the BSS (Basic Service Set) it belongs to. This helps differentiate between frames from different BSSs that share the same channel and avoid unnecessary collisions and backoffs. BSS coloring also introduces an adaptive threshold for interference, which means that Wi-Fi 6 devices can adjust the signal strength value that determines whether a channel is busy or not based on the current network environment. This allows for more efficient use of spectrum and higher throughput in dense scenarios12.

NEW QUESTION # 35
Which statements are true regarding a VXLAN implementation on Aruba Switches? (Select two.)

• A. VNIs encapsulate and decapsulate VXLAN traffic
• B. They are only available for datacenter switches (CX 8k, 9k,10k)
• C. MTU size must be increased beyond the default
• D. VTEPs encapsulate and decapsulate VXLAN traffic
• E. All Aruba CX switches support VXLAN.

Answer: A,C

Explanation:
Option A: MTU size must be increased beyond the default
This is because option A shows how to configure the MTU size for VXLAN tunnels on Aruba switches using the interface command and the vxlan command. The MTU size must be increased beyond the default value of 1500 bytes to accommodate the VXLAN header and payload2.
Therefore, option A is true regarding a VXLAN implementation on Aruba switches.
Option B: VNIs encapsulate and decapsulate VXLAN traffic
This is also true regarding a VXLAN implementation on Aruba switches. VNIs are used to encapsulate and decapsulate VXLAN traffic between two devices, such as a switch and a server. VNIs are also used to map VXLAN tunnels to overlay networks3.
Therefore, option B is also true regarding a VXLAN implementation on Aruba switches.
VXLAN is a Layer 2 encapsulation technology that substitutes the usage of VLAN numbers to label Ethernet broadcast domains with VXLAN numbers. VXLAN supports 224 Ethernet broadcast domains or VXLAN numbers. A VXLAN number ID is referred to as VNI. There is a one-to-one relationship between an Ethernet broadcast domain and a VNI. A single Ethernet broadcast domain can't have more than one VNI.

NEW QUESTION # 36
With the Aruba CX switch configuration, what is the Active Gateway feature that is used for and is unique to VSX configuration?

• A. VRID is set automatically as SVI vlan id
• B. VRRP and Active gateway are mutually exclusive on a VLAN
• C. VRRP and Active Gateway can be configured on a single VLAN for interoperability
• D. VRIDs need to be non-overlapping with VRRP

Answer: B

Explanation:
Active gateway is a first hop redundancy protocol that eliminates a single point of failure. The active gateway feature is used to increase the availability of the default gateway servicing hosts on the same subnet. An active gateway improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network. If you have enabled active gateway, VRRP is not required3. Active gateway is similar to VRRP in that routed traffic from the VSX node is sourced from the switch interface MAC and not the virtual MAC address (VMAC). Each active gateway sends a periodic broadcast hello packet to avoid VMAC aging on the access switches. The switch views the active gateway IP as a self IP address3. Active gateway is preferable over VRRP because with VRRP traffic is still pushed over the ISL link, resulting in latency in the network3. Therefore, VRRP and active gateway are mutually exclusive on a VLAN, and answer A is correct.

NEW QUESTION # 37
A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.
What statements are correct regarding the ERSPAN session that needs to be established on an AOS-CX switch'? (Select two )

• A. The encapsulation protocol is UDP.
• B. On the source AOS-CX switch, the destination specified is the administrators desktop
• C. The encapsulation protocol used is GRE.
• D. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
• E. The encapsulation protocol used is VXLAN.

Answer: B,C

Explanation:
These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator's desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc. The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.

NEW QUESTION # 39
You are building a configuration in Central that will be used for a standardized network design for small sites for your company, you want to use GUI configuration for gateways and Aps, while template configuration for switches. You need to align with Aruba best practices.
Which set of actions will satisfy these requirements?

• A. Create one group in Central for switches and a second group for APs and gateways. Create a unique site for each location, and assign devices to the appropriate site.
• B. Create one group in Central for switches a second group for APs. and a third group for gateways Create a unique site for each location, and assign devices to the appropriate site.
• C. Create a single group in Central. Create a unique site for each type of device, and assign devices to the appropriate site.
• D. Create a single group in Central. Create a unique site for each location, and assign devices to the appropriate site.

Answer: D

Explanation:
Explanation
This is because option C shows how to create a single group in Central with different configuration methods defined for each device type. For example, you can create a group with the name Group1, and within this group, you can enable template-based configuration method for switches and UI-based configuration method for Instant APs and Gateways. Aruba Central identifies both these groups under a single name (Group1). If a device type in the group is marked for template-based configuration method, the group name is prefixed with TG (TG Group1). You can use Group1 as the group ID for workflows such as user management, monitoring, reports, and audit trail2.

NEW QUESTION # 40
Describe the difference between Class of Service (CoS) and Differentiated Services Code Point (DSCP).

• A. CoS is only contained in VLAN Tag fields DSCP is in the IP Header and preserved throughout the IP packet flow
• B. They are similar and can be used interchangeably.
• C. CoS has much finer granularity than DSCP
• D. CoS is only used to determine CLASS of traffic DSCP is only used to differentiate between different Classes.

Answer: A

Explanation:
CoS and DSCP are both methods of marking packets for quality of service (QoS) purposes. QoS is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc. CoS stands for Class of Service and is a 3-bit field in the 802.1Q VLAN tag header. CoS can only be used on Ethernet frames that have a VLAN tag, and it can only be preserved within a single VLAN domain. DSCP stands for Differentiated Services Code Point and is a 6-bit field in the IP header. DSCP can be used on any IP packet, regardless of the underlying layer 2 technology, and it can be preserved throughout the IP packet flow, unless it is modified by intermediate devices.

NEW QUESTION # 41
You are troubleshooting an issue with a pair of Aruba CX 8360 switches configured with VSX Each switch has multiple VRFs. You need to find the IP address of a particular client device with a known MAC address You run the "show arp" command on the primary switch in the pair but do not find a matching entry for the client MAC address.
The client device is connected to an Aruba CX 6100 switch by VSX LAG.
Which action can be used to find the IP address successfully?

• A.
• B.
• C.
• D.

Answer: C

Explanation:
Explanation
The show arp command displays the ARP table for a specific VRF or all VRFs on the switch. The ARP table contains the IP address to MAC address mappings for hosts that are directly connected to the switch or reachable through a gateway. If the client device is connected to another switch by VSX LAG, the ARP entry for the client device will not be present on the primary switch unless it has communicated with it recently.
Therefore, to find the IP address of the client device, the administrator should run the show arp command on the secondary switch in the VSX pair, specifying the VRF name that contains the client device's subnet.

Refer to the image.

Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7

• A. The AP is configured in Mesh mode
• B. The AP is a remote access point.
• C. The AP is using a directional antenna.
• D. The AP is an outdoor access point.

Answer: C

Explanation:
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

Which feature supported by SNMPv3 provides an advantage over SNMPv2c?

• A. Community strings
• B. GetBulk
• C. Encryption
• D. Transport mapping

Answer: C

Explanation:
Explanation
Encryption is a feature supported by SNMPv3 that provides an advantage over SNMPv2c. Encryption protects the confidentiality and integrity of SNMP messages by encrypting them with a secret key. SNMPv2c does not support encryption and relies on community strings for authentication and authorization, which are transmitted in clear text and can be easily intercepted or spoofed. Transport mapping, community strings, and GetBulk are features that are common to both SNMPv2c and SNMPv3. References:

NEW QUESTION # 45
With the Aruba CX 6100 48G switch with uplinks of 1/1/47 and 1/1/48. how do you automate the process of resuming the port operational state once a loop on a client port is cleared?

• A. Configure global loop-protect re-enable-timer.
• B. Configure int 1/1/1-1/1/46 loop-protect re-enable-timer.
• C. Configure int 1/1/1-1/1/52 loop-protect disable timer.
• D. Configure global loop-protect disable timer.

Answer: B

Explanation:
Loop protection is a feature that detects and prevents loops in layer 2 networks. Loop protection can be enabled on ports, LAGs, or VLANs. When loop protection is enabled, the switch sends periodic loop protection messages on the interface and expects to receive them back. If a loop protection message is received back on the same interface, it indicates a loop and the switch takes an action to disable the interface or block traffic on it3. The loop-protect re-enable-timer command is used to configure the length of time the switch waits before re-enabling an interface that was disabled due to loop detection. The default value is 0, which means that the interface remains disabled until manually re-enabled3. To automate the process of resuming the port operational state once a loop on a client port is cleared, the loop-protect re-enable-timer command can be used with a non-zero value on the interface range that includes the client ports3. Therefore, answer C is correct.
