NEW QUESTION # 24
Match each AAA service with its correct definition (Matches may be used more than once or not at all)

Answer:

Explanation:

Explanation
AAA Authentication, Authorization, and Accounting (AAA) Authentication, Authorization, and Accounting (AAA) is a framework that provides security services for network access control . AAA consists of three components:
Authentication: The process of verifying the identity of a user or device that wants to access the network based on credentials such as username and password , certificates , tokens , etc . Authentication can use different protocols such as PAP , CHAP , EAP , RADIUS , TACACS+ , etc .
Authorization: The process of granting or denying access to network resources based on the identity and privileges of a user or device . Authorization can use different methods such as ACLs , RBAC , MAC , DAC , etc .
Accounting: The process of recording and reporting the activities and usage of network resources by users or devices . Accounting can use different formats such as syslog , SNMP , NetFlow , etc .
service. Here is my answer:
The correct match for each AAA service with its definition is:
Accounting: C. Tracking user activity on the network
Authentication: D. Who can access the network based on credentials/certificates Authorization: B. Control users access on the network The other options are not correct matches because:
A list of rules that specifies which entities are permitted or denied access: This option is a definition of an access control list (ACL) Access Control List (ACL) Access Control List (ACL) is a list of rules that specifies which entities are permitted or denied access to a network resource such as a router , switch , firewall , server , etc . ACLs can be based on different criteria such as source and destination IP addresses , port numbers , protocol types , time of day , etc . ACLs can be applied to different interfaces or directions such as inbound or outbound . ACLs can be verified by using commands such as show access-lists , show ip access-lists , debug ip packet , etc . , not an AAA service.
Who can access the network based on credentials/certificates: This option is a definition of authentication, not authorization. Authorization is the process of granting or denying access to network resources based on the identity and privileges of a user or device, not based on credentials/certificates.

NEW QUESTION # 25
What is a weakness introduced into the WLAN environment when WPA2-Personal is used for security?

• A. It uses X 509 certificates generated by a Certification Authority
• B. The Pairwise Master Key (PMK) is shared by ail users
• C. The Pairwise Temporal Key (PTK) is specific to each session
• D. It does not use the WPA 4-Way Handshake

Answer: B

Explanation:
Explanation
The weakness introduced into WLAN environment when WPA2-Personal is used for security is that PMK Pairwise Master Key (PMK) is a key that is derived from PSK Pre-shared Key (PSK) is a key that is shared between two parties before communication begins , which are both fixed. This means that all users who know PSK can generate PMK without any authentication process. This also means that if PSK or PMK are compromised by an attacker, they can be used to decrypt all traffic encrypted with PTK Pairwise Temporal Key (PTK) is a key that is derived from PMK, ANonce AuthenticatorNonce (ANonce) is a random number generated by an authenticator (a device that controls access to network resources, such as an AP), SNonce Supplicant Nonce (SNonce) is a random number generated by supplicant (a device that wants to access network resources, such as an STA), AA Authenticator Address (AA) is MAC address of authenticator, SA Supplicant Address (SA) is MAC address of supplicant using Pseudo-Random Function (PRF). PTK consists of four subkeys: KCK Key Confirmation Key (KCK) is used for message integrity check, KEK Key Encryption Key (KEK) is used for encryption key distribution, TK Temporal Key (TK) is used for data encryption, MIC Message Integrity Code (MIC) key. .
The other options are not weaknesses because:
It uses X 509 certificates generated by a Certification Authority: This option is false because WPA2-Personal does not use X 509 certificates or Certification Authority for authentication. X 509 certificates and Certification Authority are used in WPA2-Enterprise mode, which uses 802.1X and EAP Extensible Authentication Protocol (EAP) is an authentication framework that provides support for multiple authentication methods, such as passwords, certificates, tokens, or biometrics. EAP is used in wireless networks and point-to-point connections to provide secure authentication between a supplicant (a device that wants to access the network) and an authentication server (a device that verifies the credentials of the supplicant). for user authentication with a RADIUS server Remote Authentication Dial-In User Service (RADIUS) is a network protocol that provides centralized authentication, authorization, and accounting (AAA) management for users who connect and use a network service .
The Pairwise Temporal Key (PTK) is specific to each session: This option is false because PTK being specific to each session is not a weakness but a strength of WPA2-Personal. PTK being specific to each session means that it changes periodically during communication based on time or number of packets transmitted. This prevents replay attacks and increases security of data encryption.
It does not use the WPA 4-Way Handshake: This option is false because WPA2-Personal does use the WPA 4-Way Handshake for key negotiation. The WPA 4-Way Handshake is a process that allows the station and the access point to exchange ANonce and SNonce and derive PTK from PMK. The WPA
4-Way Handshake also allows the station and the access point to verify each other's PMK and confirm the installation of PTK.

What can be done to dynamically set the PoE Priority on a switch port when deploying IP cameras APs. and other PoE devices?

• A. Configure PoE power management to Dynamic Mode
• B. Configure PoE power management to Class-based Mode
• C. Enable profiling for device provisioning
• D. Enable Quick PoE on the switch modules

Answer: C

Explanation:
Explanation
Profiling is a feature that allows Aruba switches to automatically identify and classify devices connected to them based on various attributes such as MAC address, DHCP options, LLDP information, etc. Profiling can be used to dynamically set the PoE priority on a switch port based on the device type and power requirements.
For example, an IP camera may have a higher PoE priority than a printer or a PC. Profiling can also be used to apply other configuration settings such as VLANs, ACLs, QoS, etc. based on the device profile.

QoS Quality of Service (QoS) 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 can improve network performance, reduce latency, increase throughput, and prevent congestion. concept and its definition. Here is my answer:
QoS Concept:
Best Effort Service
Class of Service
Differentiated Services
WMM ====================== Definition:
d) A method where traffic is treated equally in a first-come, first-served manner a) A method for classifying network traffic at Layer 2 by marking 802.1Q VLAN Ethernet frames with one of eight service classes b) A method for classifying network traffic at Layer 3 by marking packets with one of 64 different service classes c) A method for classifying network traffic using access categories based on the IEEE 802.11e QoS standard Short But Comprehensive Explanation of Correct Answer Only: The correct match between QoS concept and its definition is as follows:
Best Effort Service: This is a method where traffic is treated equally in a first-come, first-served manner without any prioritization or differentiation. This is the default service level for most networks and applications that do not have specific QoS requirements or guarantees. Best Effort Service does not provide any assurance of bandwidth, delay, jitter, or packet loss.
Class of Service: This is a method for classifying network traffic at Layer 2 by marking 802.1Q VLAN Ethernet frames with one of eight service classes (0 to 7). These service classes are also known as IEEE
802.1p priority values or PCP Priority Code Point (PCP) is a 3-bit field in the 802.1Q VLAN tag that indicates the priority level of an Ethernet frame . Class of Service allows network devices to identify and handle different types of traffic based on their priority levels. Class of Service is typically used in LAN Local Area Network (LAN) is a network that connects devices within a limited geographic area, such as a home, office, or building environments where Layer 2 switching is predominant.
Differentiated Services: This is a method for classifying network traffic at Layer 3 by marking packets with one of 64 different service classes (0 to 63). These service classes are also known as DiffServ Code Points (DSCP) DiffServ Code Point (DSCP) is a 6-bit field in the IP header that indicates the service class of a packet . Differentiated Services allows network devices to identify and handle different types of traffic based on their service classes. Differentiated Services is typically used in WAN Wide Area Network (WAN) is a network that connects devices across a large geographic area, such as a country or continent environments where Layer 3 routing is predominant.
WMM: This is a method for classifying network traffic using access categories based on the IEEE
802.11e QoS standard. WMM stands for Wi-Fi Multimedia and it is a certification program developed by the Wi-Fi Alliance to enhance QoS for wireless networks. WMM defines four access categories (AC): Voice, Video, Best Effort, and Background. These access categories correspond to different priority levels and contention parameters for wireless traffic. WMM allows wireless devices to identify and handle different types of traffic based on their access categories.

NEW QUESTION # 30
What is the ideal Aruba access switch for a cost-effective connection to 200-380 clients, printers and APs per distribution rack?

• A. Aruba CX 6200
• B. Aruba CX 6300
• C. Aruba CX 6400
• D. Aruba CX 6000

Answer: A

Explanation:
Explanation
The ideal Aruba access switch for a cost-effective connection to 200-380 clients, printers and APs per distribution rack is the Aruba CX 6200. This switch series is a cloud-manageable, stackable access switch series that is ideal for enterprise branch offices and campus networks, as well as SMBs. The CX 6200 series offers the following benefits:
Enterprise-class connectivity: The CX 6200 series supports ACLs, robust QoS, and common protocols such as static and Access OSPF routing.
Power and speed for users and IoT: The CX 6200 series provides built-in 1/10GbE uplinks and 30W to
60W of Class 4 to Class 6 PoE for powering devices such as APs and cameras.
Scalable growth made simple: The CX 6200 series supports Aruba Virtual Switching Framework (VSF) that allows you to quickly grow your network to eight members in a single stack using high-performance built-in 10G SFP ports.
Management flexibility: The CX 6200 series supports a choice of management, including cloud-based and on-prem Central, CLI, switch Web GUI and programmability with AOS-CX operating system, and REST APIs.
The other options are not ideal because:
Aruba CX 6400: This switch series is a high-availability modular switch series that is ideal for versatile edge access to data center deployments. It offers more performance, scalability, and modularity than the CX 6200 series, but it is also more expensive and complex to deploy and manage. It may not be cost-effective for connecting 200-380 clients per distribution rack.
Aruba CX 6300: This switch series is a layer 3 stackable access and aggregation switch series that offers Smart Rate and High Power PoE. It offers more features and performance than the CX 6200 series, but it is also more expensive and may not be necessary for connecting 200-380 clients per distribution rack.
Aruba CX 6000: This switch series is a layer 2 access switch series that offers PoE. It offers less features and performance than the CX 6200 series, and it does not support VSF stacking or routing protocols. It may not be sufficient for connecting 200-380 clients per distribution rack.

NEW QUESTION # 33
Two independent ArubaOS-CX 6300 switches with Spanning Tree (STP) settings are interconnected with two cables between ports 1/1/1 and 1/1/2 All four ports have "no shutdown" and "no routing" commands How will STP forward or discard traffic on these ports?

• A. The switch with the lower MAC address will forward on both ports, while the switch with the higher MAC address will discard on one port
• B. The switch with the lower MAC address will discard on one port, while the switch with the higher MAC address will discard on one port
• C. The switch with the lower MAC address will forward on both ports, while the switch with the higher MAC address will forward on both ports
• D. The switch with the lower MAC address will discard on one port, while the switch with the higher MAC address will forward on both ports

Answer: B

Explanation:
Explanation
The way that STP Spanning Tree Protocol. STP is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network by preventing redundant paths between switches or bridges from creating loops that cause broadcast storms, multiple frame transmission, and MAC table instability. STP creates a logical tree structure that spans all of the switches in an extended network and blocks any redundant links that are not part of the tree from forwarding data packets . will forward or discard traffic on these ports is as follows:
STP will elect a root bridge among the two switches based on their bridge IDs, which are composed of a priority value and a MAC address. The switch with the lower bridge ID will become the root bridge and will forward traffic on all its ports.
STP will assign a role and a state to each port on both switches based on their port IDs, which are composed of a priority value and a port number. The port with the lower port ID will become the designated port and will forward traffic, while the port with the higher port ID will become the alternate port and will discard traffic.
In this scenario, since both switches have two cables connected between ports 1/1/1 and 1/1/2, there will be two possible paths between them, creating a loop. To prevent this loop, STP will block one of these paths by discarding traffic on one of the ports on each switch.
Assuming that both switches have the same priority value (default is 32768), the switch with the lower MAC address will have the lower bridge ID and will become the root bridge. The root bridge will forward traffic on both ports 1/1/1 and 1/1/2.
Assuming that both ports have the same priority value (default is 128), port 1/1/1 will have a lower port ID than port 1/1/2 on both switches because it has a lower port number. Port 1/1/1 will become the designated port and will forward traffic, while port 1/1/2 will become the alternate port and will discard traffic.
Therefore, the switch with the lower MAC address will discard traffic on one port (port 1/1/2), while the switch with the higher MAC address will also discard traffic on one port (port 1/1/2).

NEW QUESTION # 36
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 the 5 GHz band only.
• C. The radio is enabled in monitor or spectrum analysis mode
• D. The radio is working in mesh mode

Answer: C

Explanation:
Explanation
The solid amber radio status LED on an Aruba AP Access Point (AP) Access Point (AP) is a device that connects wireless devices to a wired network using Wi-Fi or other wireless standards . APs act as transmitters and receivers of wireless signals and provide wireless coverage for a specific area . APs can operate in different modes such as root , repeater , bridge , mesh , etc . APs can also support different features such as security , QoS , roaming , load balancing , etc . APs can be standalone devices or managed by controllers or cloud services . APs can be verified by using commands such as show ap active , show ap database , show ap bss-table , etc . indicates that the radio is enabled in monitor or spectrum analysis mode. Monitor mode is a mode that allows the AP to scan all channels and collect information about wireless traffic, interference, rogue devices, etc. Spectrum analysis mode is a mode that allows the AP to scan all channels and collect information about RF Radio Frequency (RF) Radio Frequency (RF) is a term that refers to electromagnetic waves that have frequencies between 3 kHz and 300 GHz . RF waves are used for various purposes such as communication , broadcasting , radar , navigation , remote control , etc . RF waves can be modulated by changing their amplitude , frequency , or phase to encode information . RF waves can also be affected by various factors such as attenuation , reflection , refraction , diffraction , scattering , interference , noise , etc . RF waves can be measured by using devices such as spectrum analyzers , power meters , antennas , etc . environment, noise sources, channel utilization, etc. Both modes are useful for troubleshooting and optimizing wireless performance, but they disable normal data transmission and reception on the radio.
The other options are not indicated by a solid amber radio status LED on an Aruba AP because:
Not enough PoE is provided from the switch to power both radios of the AP: This option is false because not enough PoE Power over Ethernet (PoE) Power over Ethernet (PoE) is a technology that allows network devices to receive power and data over the same Ethernet cable . PoE eliminates the need for separate power sources and cables for devices such as IP phones , cameras , access points , etc .
PoE is defined in IEEE 802.3af and IEEE 802.3at standards and supports different power classes and modes . PoE can be provided by switches or injectors that act as power sourcing equipment (PSE) and received by devices that act as powered devices (PD) . PoE can be verified by using commands suchas show power inline , show power-over-ethernet , debug ip device tracking , etc . is indicated by a blinking amber power status LED on an Aruba AP, not by a solid amber radio status LED. A blinking amber power status LED means that the AP is receiving insufficient power from the switch or injector and cannot operate normally. A solid green power status LED means that the AP is receiving sufficient power from the switch or injector and can operate normally.
The radio is working in mesh mode: This option is false because the radio working in mesh mode is indicated by a solid green radio status LED on an Aruba AP, not by a solid amber radio status LED. A solid green radio status LED means that the radio is working in normal mode or mesh mode and can transmit or receive data on the assigned channel. Mesh mode is a mode that allows the AP to connect wirelessly to other APs and form a mesh network without requiring wired connections.
The radio is working the 5 GHz band only: This option is false because the radio working in the 5 GHz band only is indicated by a solid blue radio status LED on an Aruba AP, not by a solid amber radio status LED. A solid blue radio status LED means that the radio is working in dual-band mode and can transmit or receive data on both 2.4 GHz and 5 GHz bands.

You put in a few show commands on switches EDGE1 and CORE1 to attempt to gather information to troubleshoot the issue Use the show command output images to determine the reason for the EDGE1 uplink being down

• A. LACP is not configured on the Core uplink
• B. Spanning-Tree block state is preventing the Core uplink from having connectivity to the edge
• C. The physical interfaces are not members of the correct LAG.
• D. The Core is connected to the incorrect physical interlaces

Answer: A

Explanation:
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.
