NEW QUESTION # 11
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: D
Explanation:
Explanation
Option A shows the correct commands to ensure that no rogue DHCP server will impact the network. The commands include the following steps:
* Enable DHCP snooping on the switch. DHCP snooping is a feature that prevents rogue DHCP servers from offering IP addresses to clients by filtering DHCP messages based on trusted and untrusted ports1.
* Configure VLANs 100, 110, and 120 as DHCP snooping VLANs. This means that DHCP snooping will be applied to these VLANs and any untrusted DHCP messages received on these VLANs will be dropped1.
* Configure LAG 1 as a trusted port for DHCP snooping. This means that any DHCP messages received on LAG 1 will be allowed and not filtered by DHCP snooping. LAG 1 is assumed to be connected to a legitimate DHCP server or a router that relays DHCP requests to a legitimate DHCP server1.
Option B is incorrect because it does not enable DHCP snooping on the switch or configure VLANs 100, 110, and 120 as DHCP snooping VLANs. Option C is incorrect because it does not configure LAG 1 as a trusted port for DHCP snooping. Option D is incorrect because it does not enable DHCP snooping on the switch or configure LAG 1 as a trusted port for DHCP snooping. References: 1

- A. Opportunistic key caching
- B. Authentication survivability
- C. MAC caching
- D. MAC Authentication
Answer: B
Explanation:
Explanation
Authentication survivability is a feature that allows the device to remain operational when a remote link failure occurs between a Gateway cluster and a RADIUS server that is either in the cloud or a datacenter.
Authentication survivability enables the Gateway cluster to cache successful authentication requests from the RADIUS server and use them to authenticate clients when the RADIUS server is unreachable. Authentication survivability also allows clients to use MAC caching or MAC authentication bypass (MAB) methods to access the network when the RADIUS server is down. References:

NEW QUESTION # 13
Which feature supported by SNMPv3 provides an advantage over SNMPv2c?
- A. GetBulk
- B. Encryption
- C. Transport mapping
- D. Community strings
Answer: B
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 # 18
A new network design is being considered to minimize client latency in a high-density environment. The design needs to do this by eliminating contention overhead by dedicating subcamers to clients.
Which technology is the best match for this use case?
- A. MU-MIMO
- B. QWMM
- C. Channel Bonding
- D. OFDMA
Answer: D
Explanation:
Explanation
OFDMA (Orthogonal Frequency Division Multiple Access) is a technology that can minimize client latency in a high-density environment by eliminating contention overhead by dedicating subcarriers to clients. OFDMA allows multiple clients to transmit simultaneously on different subcarriers within the same channel, reducing contention and increasing efficiency. MU-MIMO (Multi-User Multiple Input Multiple Output) is a technology that allows multiple clients to transmit simultaneously on different spatial streams within the same channel, but it does not eliminate contention overhead. QWMM (Quality of Service Wireless Multimedia) is a technology that prioritizes traffic based on four access categories, but it does not eliminate contention overhead. Channel Bonding is a technology that combines two adjacent channels into one wider channel, increasing bandwidth but not eliminating contention overhead. References:

NEW QUESTION # 20
A customer wants to provide wired security as close to the source as possible The wired security must meet the following requirements:
-allow ping from the IT management VLAN to the user VLAN
-deny ping sourcing from the user VLAN to the IT management VLAN
The customer is using Aruba CX 6300s
What is the correct way to implement these requirements?
- A. Apply an outbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
- B. Apply an outbound ACL on the user VLAN allowing temp echo-reply traffic toward the IT management VLAN
- C. Apply an inbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
- D. Apply an inbound ACL on the user VLAN allowing icmp echo-reply traffic toward the IT management VLAN
Answer: C
Explanation:
Explanation
An inbound ACL is applied to traffic entering a port or VLAN. An outbound ACL is applied to traffic leaving a port or VLAN4. To deny ping sourcing from the user VLAN to the IT management VLAN, an inbound ACL on the user VLAN should be used to filter icmp echo traffic toward the IT management VLAN. Icmp echo-reply traffic is not needed to be allowed because it is already permitted by default5. References: 4

What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)
- A. AP1 will cache the client's information and send it to the Key Management service
- B. The Key Management service receives a list of all AP1 s neighbors from AirMatch.
- C. A client associates and authenticates with the AP2 after roaming from AP1
- D. The Key Management service receives from AirMatch a list of all AP2's neighbors
- E. The Key Management service then generates R1 keys for AP2's neighbors.
Answer: B,E
Explanation:
Explanation
Key Management is a service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) to optimize roaming performance for wireless clients. Key Management works with AirMatch, a service that optimizes radio resource management for Aruba APs, to pre-generate and distribute R1 keys for neighboring APs before a client roams. When a wireless device is roaming from AP1 to AP2, the following steps are part of the Key Management workflow3:
* The client associates and authenticates with AP1 using 802.1X or PSK methods.
* The Key Management service caches the client's information and generates an R0 key for the client.
* The Key Management service receives a list of all AP1's neighbors from AirMatch.
* The Key Management service then generates R1 keys for AP1's neighbors using the R0 key and sends them to the corresponding APs.
* When the client roams to AP2, one of AP1's neighbors, it performs an 802.11r fast transition using the pre-generated R1 key without needing to re-authenticate.

NEW QUESTION # 24
Describe the difference between Class of Service (CoS) and Differentiated Services Code Point (DSCP).
- A. They are similar and can be used interchangeably.
- B. CoS is only contained in VLAN Tag fields DSCP is in the IP Header and preserved throughout the IP packet flow
- 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: B
Explanation:
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.

* AP1 has a radio that generates a 10 dBm signal
* AP2 has a radio that generates a 11 dBm signal
* AP1 has an antenna with a gain of 9 dBi
* AP2 has an antenna with a gain of 12 dBi.
* The antenna cable for AP1 has a 2 dB loss
* The antenna cable for AP2 has a 3 dB loss
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for APT?
- A. 26 dBm
- B. 17 dBm
- C. -12 dBm
- D. 30 dBm
Answer: D
Explanation:
Explanation
The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 30 dBm. EIRP is the product of the transmitter power (in dBm) and the antenna gain (in dBi) minus the cable loss (in dB). For AP1, EIRP = 10 dBm + 9 dBi - 2 dB = 17 dBm. For AP2, EIRP = 11 dBm + 12 dBi - 3 dB = 20 dBm. References:

NEW QUESTION # 30
The customer needs a network hardware refresh to replace an aging Aruba 5406R core switch pair using spanning tree configuration with Aruba CX 8360-32YC switches What is the benefit of VSX clustering with the new solution?
- A. dual Aruba AP LAN port connectivity for PoE redundancy
- B. faster MSTP converge processing
- C. stacked data-plane
- D. dual control plane provides better resiliency
Answer: D
Explanation:
Explanation
VSX clustering is a feature that allows two Aruba CX switches to operate as a single logical device, providing high availability, scalability, and simplified management. VSX clustering has several benefits over spanning tree configuration, such as:
* Dual control plane provides better resiliency. Unlike stacking, where switches share a single control plane, VSX switches have independent control planes that synchronize their states over an inter-switch link (ISL). This means that if one switch fails or reboots, the other switch can continue to operate without affecting traffic flows or network services.
* Active-active forwarding provides better performance. Unlike spanning tree, where some links are blocked to prevent loops, VSX switches use all available links for forwarding traffic, providing load balancing and increased bandwidth utilization.
* Multichassis LAG provides better redundancy. Unlike single-chassis LAG, where all member ports belong to one switch, VSX switches can form multichassis LAGs with downstream or upstream devices, where member ports are distributed across both switches. This provides link redundancy and seamless failover in case of switch or port failure.

NEW QUESTION # 31
You need to ensure that voice traffic sent through an ArubaOS-CX switch arrives with minimal latency What is the best scheduling technology to use for this task?
- A. QoS shaping
- B. DWRR queuing
- C. Rate limiting
- D. Strict queuing
Answer: D
Explanation:
Explanation
Strict queuing is the best scheduling technology to use for voice traffic on an AOS-CX switch. Scheduling is a mechanism that determines how packets are transmitted from different queues on an egress port. Strict queuing is a scheduling method that gives the highest priority queue absolute preference over all other queues, regardless of their size or utilization. Voice traffic should be assigned to the highest priority queue and scheduled with strict queuing to ensure minimal latency and jitter. The other options are incorrect because they are either not scheduling methods or not optimal for voice traffic. References:

- A. All APs need to be from the AP-5xx series and AP-6xx series which are Wi-Fi CERTIFIED 6.
- B. The Aruba AOS10 APs installed have to be converted to controlled mode
- C. The APs and the controller are Wi-Fi CERTIFIED for WMM which is enabled
- D. The AP needs to be connected via a tagged VLAN to the wired port
- E. The Client must be Wi-Fi CERTIFIED for WMM and configured for WMM marking.
Answer: C,E
Explanation:
Explanation
These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work. References:
