Question 1

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?



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.


Question 2

A large retail client is looking to generate a rich set of contextual data based on the location information of wireless clients in their stores Which standard uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP?



Answer : B

802.11mc is a standard that uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP. 802.11mc defines a protocol for exchanging FTM frames between an AP and a client, which contain timestamps that indicate when the frames were transmitted and received. By measuring the RTT of these frames, the AP or the client can estimate their distance based on the speed of light. The other options are incorrect because they either do not use RTT or FTM or do not exist as standards.

Question 3

Your customer is interested in hearing more about how roles can help keep consistent policy enforcement in a distributed overlay fabric How would you explain this concept to them''



Answer : C

This is the correct explanation of how roles can help keep consistent policy enforcement in a distributed overlay fabric. Roles are used to assign group based policy IDs (GBPs) to devices after they authenticate with ClearPass or a local database. GBPs are then used to tag the traffic from the devices and send them to the ingress VTEP, which applies the GBP on the VXLAN header. The egress VTEP then enforces the policy based on the GBP and the destination device. The other options are incorrect because they either do not describe the correct sequence of events or do not use the correct terms.

Question 4

A new network design is being considered to minimize client latency in a high-density environment. The design needs to do this by eliminating contention overhead by dedicating subcarriers to clients.

Which technology is the best match for this use case?



Answer : A

OFDMA (Orthogonal Frequency Division Multiple Access) is a technology that can minimize client latency in a high-density environment by eliminating contention overhead by dedicating subcarriers to clients. OFDMA allows multiple clients to transmit simultaneously on different subcarriers within the same channel, reducing contention and increasing efficiency. MU-MIMO (Multi-User Multiple Input Multiple Output) is a technology that allows multiple clients to transmit simultaneously on different spatial streams within the same channel, but it does not eliminate contention overhead. QWMM (Quality of Service Wireless Multimedia) is a technology that prioritizes traffic based on four access categories, but it does not eliminate contention overhead. Channel Bonding is a technology that combines two adjacent channels into one wider channel, increasing bandwidth but not eliminating contention overhead.

Question 5

You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?



Answer : B

To establish a keepalive connection between two Aruba CX 8325 switches for VSX configuration, you need to use a routed port in custom VRF. A routed port is a physical port that acts as a layer 3 interface and does not belong to any VLAN. A custom VRF is a virtual routing and forwarding instance that provides logical separation of routing tables. By using a routed port in custom VRF, you can isolate the keepalive traffic from other traffic and prevent routing loops or conflicts. The other options are incorrect because they either do not use a routed port or do not use a custom VRF.

Question 6

You are configuring an SVI on an Aruba CX switch that needs to have the following characteristics:

* VLANID = 25

. IPv4 address 10 105 43 1 with mask 255 255 255.0

* IPv6 address fd00:5708::f02d:4df6 with a 64 bit prefix length

* member of VRF eng

* VRF eng and VLAN 25 have not yet been created

Which command lists will satisfy the requirements with the least number of commands?

A)

B)

C)

D)



Answer : C

The other options either use more commands or do not create the VRF or the VLAN.

Option C uses the following commands:

vrf eng: This command creates a VRF named eng and enters the VRF configuration mode1.

vlan 25: This command creates a VLAN with ID 25 and enters the VLAN configuration mode2.

interface vlan 25: This command creates an SVI on VLAN 25 and enters the interface configuration mode3.

ip address 10.105.43.1/24 ipv6 address fd00:5780::102d:4df6/64 vrf attach eng: This command assigns an IPv4 address of 10.105.43.1 with a subnet mask of 255.255.255.0 and an IPv6 address of fd00:5780::102d:4df6 with a prefix length of 64 to the SVI, and attaches it to the VRF eng.


Question 7

A customer wants to enable wired authentication across all their CX switches One of the requirements is that the switch must be able to authenticate a single computer connected through a VoIP phone.

Which feature should be enabled to support this requirement?



Answer : A

Multi-Domain Authentication is the feature that should be enabled to support the requirement that the switch must be able to authenticate a single computer connected through a VoIP phone. Multi-Domain Authentication is a feature that allows an Aruba CX switch to apply different authentication methods and policies to different devices connected to the same port. For example, a VoIP phone and a computer can be connected to the same port using a single cable, but they can be authenticated separately using different credentials and assigned to different VLANs. The other options are incorrect because they either do not support multiple devices on the same port or do not provide authentication.
