NEW QUESTION # 88
What can be done to dynamically set the PoE Priority on a switch port when deploying IP cameras APs. and other PoE devices?
Answer: B
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.References:

NEW QUESTION # 89
What is a weakness introduced into the WLAN environment when WPA2-Personal is used for security?
Answer: D
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.
NEW QUESTION # 90
You are in a meeting with a customer where you are asked to explain the network redundancy feature VRRP. What is the correct statement for this feature?
Answer: A
Explanation:
VRRP is an open, standards-based protocol that provides IP gateway redundancy by allowing multiple routers to share a virtual IP address, with one acting as the active gateway.
NEW QUESTION # 91
When measuring signal strength, dBm is commonly used and 0 dBm corresponds to 1 mW power.
What does -20 dBm correspond to?
Answer: D
Explanation:
dBm is a unit of power that measures the ratio of a given power level to 1 mW. The formula to convert dBm to mW is: P(mW) = 1mW * 10
