What is true regarding 802.11k?
- A. It reduces roaming delay by pre-authenticating clients with multiple target APs before a client roams to an AP
- B. It considers several metrics before it determines if a client should be steered to the 5GHz band, including client RSSI
- C. It provides mechanisms for APs and clients to dynamically measure the available radio resources.
- D. It extends radio measurements to define mechanisms for wireless network management of stations
Answer: C
Explanation:
Explanation
802.11k is a standard that provides mechanisms for APs and clients to dynamically measure the available radio resources in a wireless network. 802.11k defines radio resource management (RRM) functions, such as neighbor reports, link measurement, beacon reports, etc., that allow APs and clients to exchange information about the RF environment and make better roaming decisions. The other options are incorrect because they describe other standards, such as 802.11r, 802.11v, or 802.11ax. References:

NEW QUESTION # 20
Which feature supported by SNMPv3 provides an advantage over SNMPv2c?
- A. Encryption
- B. Transport mapping
- C. Community strings
- D. GetBulk
Answer: A
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 # 21
A company deployed Dynamic Segmentation with their CX switches and Gateways After performing a security audit on their network, they discovered that the tunnels built between the CX switch and the Aruba Gateway are not encrypted. The company is concerned that bad actors could try to insert spoofed messages on the Gateway to disrupt communications or obtain information about the network.
Which action must the administrator perform to address this situation?
- A. Enable Secure Mode Enhanced
- B. Enable GRE security
- C. Enable Enhanced PAPI security
- D. Enable Enhanced security
Answer: D
Explanation:
Explanation
To address the situation of unencrypted tunnels between the CX switch and the Aruba Gateway, the administrator must enable Enhanced security on both devices. Enhanced security is a feature that provides encryption and authentication for GRE tunnels between CX switches and Aruba Gateways using IPSec.
Enhanced security can be enabled globally or per tunnel on both devices using CLI commands or Web UI options. The other options are incorrect because they either do not provide encryption or authentication for GRE tunnels or do not exist as features. References:

NEW QUESTION # 22
What is one advantage of using OCSP vs CRLs for certificate validation?
- A. higher availability for certificate validation
- B. supports longer certificate validity periods
- C. reduces latency between the time a certificate is revoked and validation reflects this status
- D. less complex to implement
Answer: C
Explanation:
Explanation
OCSP is a protocol that allows clients to query the CA or a trusted responder for the status of a specific certificate. OCSP requests and responses are smaller and faster than CRLs, and they can provide real-time information about the revocation status of a certificate12. CRLs are lists of all revoked certificates that are downloaded from the CA. CRLs can present issues, as they can become outdated and have to be downloaded frequently13. Therefore, OCSP reduces latency between the time a certificate is revoked and validation reflects this status. References: 1 https://sectigostore.com/blog/ocsp-vs-crl-whats-the-difference/ 2

NEW QUESTION # 23
What are two advantages of splitting a larger OSPF area into a number of smaller areas? (Select two )
- A. It reduces the total number of LSAs
- B. It extends the LSDB
- C. it simplifies the configuration.
- D. It reduces processing overhead.
- E. It increases stability
Answer: D,E
Explanation:
Explanation
Splitting a larger OSPF area into a number of smaller areas has several advantages for network scalability and performance. Some of these advantages are:
* It increases stability by limiting the impact of topology changes within an area. When a link or router fails in an area, only routers within that area need to run the SPF algorithm and update their routing tables. Routers in other areas are not affected by the change and do not need to recalculate their routes.
* It reduces processing overhead by reducing the size and frequency of link-state advertisements (LSAs).
LSAs are packets that contain information about the network topology and are flooded within an area.
By dividing a network into smaller areas, each area has fewer LSAs to generate, store, and process,
* which saves CPU and memory resources on routers.
* It reduces bandwidth consumption by reducing the amount of routing information exchanged between areas. Routers that connect different areas, called area border routers (ABRs), summarize the routing information from one area into a single LSA and advertise it to another area. This reduces the number of LSAs that need to be transmitted across area boundaries and saves network bandwidth.

NEW QUESTION # 24
Refer to the exhibit.
With Core-1. what is the default value for config-revision?
- A. 0. 0
- B. 1-0
- C. 0
- D. 1
Answer: C
Explanation:
Explanation
The default value for config-revision on Core-1 is 0. Config-revision is a parameter that indicates the configuration version of a VSX pair. It is used to synchronize the configuration between the VSX peers and to detect any configuration mismatch. The config-revision value is set to 0 by default on both VSX peers and is incremented by 1 every time a configuration change is made on either peer. The other options are incorrect because they do not reflect the default value of config-revision. References:

A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working across the campus which is connected via layer-3. The legacy devices are connected to Aruba CX 6300 switches throughout the campus.
Which technology minimizes flooding so the legacy application can work efficiently?
- A. Generic Routing Encapsulation (GRE)
- B. EVPN-VXLAN
- C. Ethernet over IP (EolP)
- D. Static VXLAN
Answer: B
Explanation:
Explanation
EVPN-VXLAN is a technology that allows layer-2 communication across layer-3 networks by using Ethernet VPN (EVPN) as a control plane and Virtual Extensible LAN (VXLAN) as a data plane3. EVPN-VXLAN can be used to support legacy applications that communicate at layer-2 across different campuses or data centers that are connected via layer-3. EVPN-VXLAN minimizes flooding by using BGP to distribute MAC addresses and IP addresses of hosts across different VXLAN segments3. EVPN-VXLAN also provides benefits such as loop prevention, load balancing, mobility, and scalability3. References: 3

NEW QUESTION # 26
Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements After the configuration was complete, it was noted that a user assigned with the administrators role did not have the appropriate level of access on the switch.
The user was not limited to viewing nonsensitive configuration information and a level of 1 was not assigned to their role Which default management role should have been assigned for the user?
- A. sysadmin
- B. helpdesk
- C. config
- D. operators
Answer: B
Explanation:
Explanation
The helpdesk role is the default management role that should have been assigned for the user who needs to view nonsensitive configuration information. The helpdesk role has a level of 1 and allows read-only access to most commands except those related to security or passwords. The administrators role has a level of 15 and allows full read-write access to all commands. The operators role has a level of 5 and allows read-write access to most commands except those related to security or passwords. The config role has a level of 10 and allows read-write access to all commands except those related to security or passwords. References:

NEW QUESTION # 27
Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?
- A. Air Monitor
- B. Dual Mode
- C. Spectrum Monitor
- D. Hybrid Mode
Answer: C
Explanation:
Explanation
Spectrum Monitor is an Aruba AP mode that is sending captured RF data to Aruba Central for waterfall plot.
Spectrum Monitor is a mode that allows an AP to scan all channels in both 2.4 GHz and 5 GHz bands and collect information about the RF environment, such as interference sources, noise floor, channel utilization, etc. The AP then sends this data to Aruba Central, which is a cloud-based network management platform that can display the data in various formats, including waterfall plot. Waterfall plot is a graphical representation of the RF spectrum over time, showing the frequency, amplitude, and duration of RF signals. The other options are incorrect because they are either not AP modes or not sending RF data to Aruba Central. References:

NEW QUESTION # 29
You are setting up a customer's 15 headless loT devices that do not support 802.1X. What should you use?
- A. Clearpass with WPA3-AES
- B. Multiple Pre-Shared Keys (MPSK) Local
- C. Multiple Pre-Shared Keys (MPSK) with WPA3-AES
- D. Clearpass with WPA3-PSK
Answer: B
Explanation:
Explanation
MPSK Local is a feature that can be used to set up 15 headless IoT devices that do not support 802.1X authentication. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require 802.1X authentication, which is not supported by the IoT devices, or WPA3 encryption, which is not supported by Aruba CX switches.

NEW QUESTION # 30
You are deploying a bonded 40 MHz wide channel What is the difference in the noise floor perceived by a client using this bonded channel as compared to an unbonded 20MHz wide channel?
- A. 3dB
- B. 2dB
- C. 4dB
- D. 8dB
Answer: A
Explanation:
Explanation
The difference in the noise floor perceived by a client using a bonded 40 MHz wide channel as compared to an unbonded 20 MHz wide channel is 3 dB. The noise floor is the level of background noise in a given frequency band. When two adjacent channels are bonded, the noise floor increases by 3 dB because the bandwidth is doubled and more noise is captured. The other options are incorrect because they do not reflect the correct relationship between bandwidth and noise floor. References:

NEW QUESTION # 31
Which statement best describes QoS?
- A. Identifying specific traffic for special treatment
- B. Identifying the quality of the connection
- C. Determining which traffic passes specified quality metrics
- D. Scoring traffic based on the quality of the contents
Answer: A
Explanation:
Explanation
QoS stands for Quality of Service and is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc3. QoS involves identifying specific traffic for special treatment and applying policies and actions to improve its performance or meet certain service level agreements (SLAs)3. QoS can help network devices to manage congestion, delay, jitter, packet loss, bandwidth allocation, etc., for different types of traffic3. QoS can be implemented at various layers of the network stack and across different network domains. References: 3

NEW QUESTION # 32
For the Aruba CX 6400 switch, what does virtual output queueing (VOQ) implement that is different from most typical campus switches?
- A. per port ASICs
- B. large ingress packet buffers
- C. VSX
- D. large egress packet buffers
Answer: B
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 # 34
Review the exhibit.
You are troubleshooting an issue with a 10 102.39 0/24 subnet which is also VLAN 1000 used Tor wireless clients on a pair of Aruba CX 8360 switches The subnet SVI is configured on the 8360 pair, and the DHCP server is a Microsoft Windows Server 2022 Standard with an IP address of 10 200 1.100. The 10.102.250.0/24 subnet is used for switch management.
A large number of DHCP requests are failing You are observing sporadic DHCP behavior across clients attached to the CX 6100 switch.
Which action may help fix the issue?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Explanation
Option B is the correct action that may help fix the issue of sporadic DHCP behavior across clients attached to the CX 6100 switch. Option B enables DHCP relay on VLAN 1000 interface on Core-1 switch, which allows DHCP requests from clients in VLAN 1000 to be forwarded to the DHCP server in a different subnet (10.200.1.100). Without DHCP relay, clients in VLAN 1000 cannot obtain IP addresses from the DHCP server because they are in different broadcast domains. The other options are incorrect because they either do not enable DHCP relay or do not configure it correctly. References:

NEW QUESTION # 35
Your customer is interested in hearing more about how roles can help keep consistent policy enforcement in a distributed overlay fabric How would you explain this concept to them''
- A. Group Based Policy ID is applied on ingress VTEP after device authentication and policy is enforced on egress VTEP
- B. Role-based policies are tied to IP addresses which have an advantage over IP-based policies and role names are sent between VTEPs
- C. Group Based Policy ID is applied on egress VTEP after device authentication and policy is enforced on ingress VTEP
- D. Role-based policies enhance User Based Tunneling across the campus network and the policy traffic is protected with iPsec
Answer: A
Explanation:
Explanation
This is the correct explanation of how roles can help keep consistent policy enforcement in a distributed overlay fabric. Roles are used to assign group based policy IDs (GBPs) to devices after they authenticate with ClearPass or a local database. GBPs are then used to tag the traffic from the devices and send them to the ingress VTEP, which applies the GBP on the VXLAN header. The egress VTEP then enforces the policy based on the GBP and the destination device. The other options are incorrect because they either do not describe the correct sequence of events or do not use the correct terms. References:

NEW QUESTION # 37
You are doing tests in your lab and with the following equipment specifications
* 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. -12 dBm
- B. 30 dBm
- C. 17 dBm
- D. 26 dBm
Answer: B
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 # 38
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 inbound ACL on the user VLAN allowing icmp echo-reply traffic toward the IT management VLAN
- B. Apply an inbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
- C. Apply an outbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
- D. Apply an outbound ACL on the user VLAN allowing temp echo-reply traffic toward the IT management VLAN
Answer: B
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
