HP Updated HPE7-A01 Exam Questions and Answers by jeevan

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.

802.3bz is a standard for Ethernet over twisted pair at speeds of 2.5 and 5 Gbit/s. These use the same cabling as the ubiquitous Gigabit Ethernet, yet offer higher speeds. The resulting standards are named 2.5GBASE-T and 5GBASE-T.

Option A: 2.5Gb and 5Gb Ethernet ports

This is because option A shows how to identify the speed of an Ethernet port based on its name and the standard it supports. A port that supports 2.5GBASE-T or 5GBASE-T is a multi-gigabit port that can operate at speeds of up to 2.5 Gbit/s or 5 Gbit/s over twisted pair cables23.

Therefore, option A is correct.

AOS-CX Active Gateway is used with a VSX pair to provide an active-active first-hop gateway. Both VSX peers share the same virtual IP address and virtual MAC address (VMAC), allowing either peer to route traffic received from downstream hosts.

HPE Aruba Networking documents that each Active Gateway periodically sends a broadcast hello packet so that downstream access switches continue learning the Active Gateway VMAC and do not age it out of their MAC address tables . HPE Support

For this Active Gateway hello mechanism, the relevant implementation is a Layer 2, non-IP Ethernet packet . This is consistent with its purpose: the packet is used primarily to refresh Layer 2 MAC learning for the shared VMAC rather than to establish an IP-layer neighbor relationship.

The other answers correspond to unrelated mechanisms. UDP port 5555 is associated in Aruba environments with functions such as AP packet-capture traffic, not VSX Active Gateway hello operation. Aruba Networks TCP port 6363 and multicast address 224.0.1.3 are likewise not used for Active Gateway hello messages.

Therefore, the correct answer is D. Non-IP Ethernet packet .
