What does the 802.3bz standard describe?

Correct Answer:A
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.

You are helping an onsite network technician bring up an Aruba 9004 gateway with ZTP for a branch office The technician was to plug in any port for the ZTP process to start Thirty minutes after the gateway was plugged in new users started to complain they were no longer able to get to the internet. One user who reported the issue stated their IP address is 172.16 0.81 However, the branch office network is supposed to be on 10.231 81.0/24.
What should the technician do to alleviate the issue and get the ZTP process started correctly?

Correct Answer:B
Aruba 9004 gateway supports ZTP on port G0/0/0 by default1. If the gateway
is connected to a different port, such as G0/0/V1, it will not be able to communicate with Aruba Activate and Aruba Central, which are required for ZTP2. Moreover, port G0/0/V1 is configured as a DHCP server by default, which can cause IP address conflicts with the existing network3. Therefore, the technician should move the cable on the gateway to port G0/0/0, which will allow the gateway to obtain an IP address from the network DHCP server and start the ZTP process. The other options are not correct because they will not solve the issue or enable ZTP. For example, option D will not work because factory defaulting and rebooting the gateway will not change the port configuration or behavior3.

In AOS 10. which session-based ACL below will only allow ping from any wired station to wireless clients but will not allow ping from wireless clients to wired stations"? The wired host ingress traffic arrives on a trusted port.

Correct Answer:D
A session-based ACL is applied to traffic entering or leaving a port or VLAN based on the direction of the session initiation. To allow ping from any wired station to wireless clients but not vice versa, a session-based ACL should be used to deny icmp echo traffic from any source to any destination, and then permit icmp echo-reply traffic from any source to user destination. The user role represents wireless clients in AOS 10. References: https://techhub.hpe.com/eginfolib/Aruba/OS-CX_10.04/5200-6692/GUID- BD3E0A5F-FE4C-4B9B-BE1D-FE7D2B9F8C3A.html

Which feature allows the device to remain operational when a remote link failure occurs between a Gateway cluster and a RADIUS server that is either in the cloud or a datacenter?

Correct Answer:C
Authentication survivability is a feature that allows the device to remain operational when a remote link failure occurs between a Gateway cluster and a RADIUS server that is either in the cloud or a datacenter. Authentication survivability enables the Gateway cluster to cache successful authentication requests from the RADIUS server and use them to authenticate clients when the RADIUS server is unreachable. Authentication survivability also allows clients to use MAC caching or MAC authentication bypass (MAB) methods to access the network when the RADIUS server is down.

DRAG DROP
Match the topics of an AOS10 Tunneled mode setup between an AP and a Gateway. (Options may be used more than once or not at all.)

Solution:


Does this meet the goal?

Correct Answer:A

DRAG DROP
Match the terms below to their characteristics (Options may be used more than once or not at all.)

Solution:
a) A device with IP address 10.1.3.7 in a network wants to send the traffic stream to a device with IP address 10.13.4.2 in the other network -> Unicast
b) One/more senders and one/more recipients participate in data transfer traffic ->
Multicast
c) Sent to all hosts on a remote network -> IP Directed Broadcast
d) Sent to all NICs on the same network segment as the source NIC -> Broadcast
References: 1 https://www.thestudygenius.com/unicast-broadcast-multicast/
The terms broadcast, IP directed broadcast, multicast, and unicast are different types of communication or data transmission over a network. They differ in how many devices are involved in the communication and how they address the messages. The following table summarizes the characteristics of each term1:
