Which part of the WPA Key Hierarchy is used to encrypt and/or decrypt data''
- A. Pairwise Temporal Key (PTK)
- B. Pairwise Master Key (PMK)
- C. Key Confirmation Key (KCK)
- D. number used once (nonce)
Answer: A
Explanation:
Explanation
The part of WPA Key Hierarchy that is used to encrypt and/or decrypt data is Pairwise Temporal Key (PTK).
PTK is a key that is derived from 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 , ANonce Authenticator Nonce (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 randomnumber 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 subkey that is specifically used for data encryption is TK Temporal Key (TK). TK is also known as Pairwise Transient Key (PTK). TK changes periodically during communication based on time or number of packets transmitted.
The other options are not part of WPA Key Hierarchy because:
PMK: PMK is not part of WPA Key Hierarchy, but rather an input for deriving PTK.
KCK: KCK is part of WPA Key Hierarchy, but it is not used for data encryption, but rather for message integrity check.
Nonce: Nonce is not part of WPA Key Hierarchy, but rather an input for deriving PTK.

NEW QUESTION # 20
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 both CX switches
- B. Virtual IP uses SVI IP address synced with VSX
- C. Virtual IP is active on the primary VSX switch
Virtual floating IP will failover in case of a failure
Answer: C
Explanation:
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.

NEW QUESTION # 21
Match the phase of message processing with the Open Systems interconnection (OSl) layer.
Answer:
Explanation:
Explanation
Layer: 1) Physical layer Phase of Message Processing: d) Organize the data into bits Layer: 2) Data Link layer Phase of Message Processing: c) Organize the data into frames Layer: 3) Network layer Phase of Message Processing: b) Organize the data into packets Layer: 4) Transport layer Phase of Message Processing: a) Organize the data into segments The OSI model divides the networking process into seven layers, each representing a different step of the transmission chain. Each layer has its own function and is responsible for well-defined tasks. User data passes sequentially from the highest layer down through the lower layers until the device transmits it externally. The lowest layer, the physical layer, converts the data into bits that can be sent over a physical medium. The second layer, the data link layer, organizes the bits into frames that can be transmitted over a link between two nodes. The third layer, the network layer, organizes the frames into packets that can be routed across a network of nodes. The fourth layer, the transport layer, organizes the packets into segments that can provide reliable and error-free communication between two end points12. References: 1

NEW QUESTION # 22
When using an Aruba standalone AP you select "Native VLAN" for the Client VLAN Assignment In which subnet will the client IPs reside?
- A. The same subnet as the Aruba ESP gateway
- B. The same subnet as the mobility controller
- C. The same subnet as the mobility conductor
- D. The same subnet as the access point
Answer: D
Explanation:
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.

NEW QUESTION # 23
Which commands are used to set a default route to 10.4.5.1 on an Aruba CX switch when ln-band management using an SVl is being used?
- A. ip route 0 0 0.070 10.4 5.1 vrf mgmt
- B. iP default-gateway 10.4.5.1
- C. ip route 0.0 0 0/0 10.4.5.1
- D. default-gateway 10.4.5.1
Answer: C
Explanation:
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 it

NEW QUESTION # 24
What does the status of "ALFOE" mean when checking LACP with "show lacp interfaces'"?
- A. LACP is working fine with no problems
- B. LACP is in a synchronizing process
- C. LACP is not configured on the peer side
- D. The interface on the local switch is configured as static-LAG
Answer: A
Explanation:
Explanation
The status of "ALFOE" means that LACP Link Aggregation Control Protocol (LACP) is a network protocol that provides dynamic negotiation of link aggregation between two devices. LACP allows multiple physical links to be combined into a single logical link for increased bandwidth, redundancy, and load balancing. LACP is defined in IEEE 802.3ad standard. is working fine with no problems when checking LACP with "show lacp interfaces". The status of "ALFOE" is an acronym that stands for:
A: Active - The interface is actively sending LACP packets to negotiate link aggregation with the peer device.
L: Link Up - The interface has physical connectivity with the peer device.
F: Aggregatable - The interface can be aggregated with other interfaces into a single logical link.
D: Synchronized - The interface has successfully negotiated link aggregation parameters with the peer device and can transmit or receive traffic on the logical link.
E: Collecting/Distributing - The interface is collecting incoming traffic from the peer device and distributing outgoing traffic to the peer device on the logical link.
The other options are not correct because:
The interface on the local switch is configured as static-LAG: This option is false because static-LAG does not use LACP to negotiate link aggregation. Static-LAG requires manual configuration of link aggregation parameters on both devices and does not have any status indicators.
LACP is not configured on the peer side: This option is false because if LACP is not configured on the peer side, the status of the interface would be "ALF-" instead of "ALFOE". This means that the interface would not be synchronized or collecting/distributing with the peer device.
LACP is in a synchronizing process: This option is false because if LACP is in a synchronizing process, the status of the interface would be "ALF-O" instead of "ALFOE". This means that the interface would not be collecting/distributing with the peer device.

Multiple Pre-Shared Key (MPSK) is a feature that allows device-specific or group-specific passphrases to securely add headless devices to the WLAN Wireless Local Area Network. WLAN is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building. . MPSK enhances the WPA2 PSK Wi-Fi Protected Access 2 Pre-Shared Key. WPA2 PSK is a method of securing your network using WPA2 with the use of the optional Pre-Shared Key (PSK) authentication, which was designed for home users without an enterprise authentication server. mode by allowing different PSKs for different devices on the same SSID Service Set Identifier. SSID is a case-sensitive, 32 alphanumeric character unique identifier attached to the header of packets sent over a wireless local-area network (WLAN). The SSID acts as a password when a mobile device tries to connect to the basic service set (BSS) - a component of the IEEE
802.11 WLAN architecture. . MPSK passwords can be generated or user-created and are managed by ClearPass Policy Manager12. References:
