An inbound ACL is applied to traffic entering a port or VLAN.  An outbound ACL is applied to traffic leaving a port or VLAN 4 . 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 default 5 .

The important advantage supplied by SNMPv3 is enhanced security, including authentication and message integrity . SNMPv3 employs a User-based Security Model in which authentication protocols such as MD5 or the SHA family can validate the sender and verify that the SNMP message has not been altered during transmission. HPE Aruba specifically documents SNMPv3 authentication protocols and recommends SNMPv3 because it provides authentication and strong privacy mechanisms that are absent from SNMPv2c. Aruba Networking

SNMPv2c relies on community strings , which are transmitted without the stronger user-based authentication and privacy protections available in SNMPv3. Aruba notes that SNMPv1 and SNMPv2c community names can be transmitted in clear text, whereas SNMPv3 supports authenticated users and encrypted management traffic. Aruba Networking

Options A and B are not unique SNMPv3 advantages. 64-bit counters were introduced with SNMPv2, particularly through Counter64 objects, and GetBulk was also introduced with SNMPv2 to improve retrieval efficiency. Option C is actually characteristic of SNMPv1/v2c rather than an SNMPv3 improvement.

Consequently, the distinguishing SNMPv3 feature among the available answers is message integrity .

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 certificate 1 2 . 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  CRLs can present issues, as they can become outdated and have to be downloaded frequently 1 3 .  Therefore, OCSP reduces latency between the time a certificate is revoked and validation reflects this status.

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.
