Demo Questions

Question 1
Two AOS-CX switches are configured with VSX at the the Access-Aggregation layer where servers attach to them An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the VSX switches.
   
What is correct about access from the servers to the Core? (Select two.)
  1. Server 1 can access the core layer via the keepalrve link
  2. Server 2 can access the core layer via the keepalive link
  3. Server 2 cannot access the core layer.
  4. Server 1 can access the core layer via both uplinks
  5. Server 1 and Server 2 can communicate with each other via the core layer
  6. Server 1 can access the core layer on only one uplink
Correct answer: DE
Explanation:
These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question.Reference: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-

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?
  1. 802.11ah
  2. 802.11mc
  3. 802.11be
  4. 802.11V
Correct answer: B
Explanation:
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.Reference: https://www.arubanetworks.com/assets/wp/WP_WiFi6.pdf https://www.arubanetworks.com/assets/ds/DS_AP510Series.pdf

Question 3
You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?
  1. SVI, VLAN trunk allowed all on ISL in default VRF
  2. routed port in custom VRF
  3. loopback 0 and OSPF area 0 in default VRF
  4. SVI, VLAN trunk allowed all on ISL in custom VRF
Correct answer: B
Explanation:
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.Reference: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch07.html https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch02.html

Question 4
Which method is used to onboard a new UXI in an existing environment with 802 1X authentication? (The sensor has no cellular connection)
  1. Use the UXI app on your smartphone and connect the UXI via Bluetooth
  2. Use the Aruba installer app on your smartphone to scan the barcode
  3. Connect the new UXI from an already installed one and adjust the initial configuration.
  4. Use the CLI via the serial cable and adjust the initial configuration.
Correct answer: A
Explanation:
To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address, etc. The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth.Reference: https://www.arubanetworks.com/products/network-management-operations/analytics-monitoring/user-experience-insight-sensors/ https://help.centralonprem.arubanetworks.com/2.5.4/documentation/online_help/content/nms-on-prem/aos-cx/get-started/uxi-sensor.htm

Question 5
A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working to a remote site connected via layer-3 All legacy devices are connected to a dedicated Aruba CX 6200 switch at each site.
What technology on the Aruba CX 6200 could be used to meet this requirement?
  1. Inclusive Multicast Ethernet Tag (IMET)
  2. Ethernet over IP (EolP)
  3. Generic Routing Encapsulation (GRE)
  4. Static VXLAN
Correct answer: A
Explanation:
VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer-3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches.Reference:https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch03.html https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch05.html

Question 6
Refer to the image.
   
Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7
  1. The AP is a remote access point.
  2. The AP is using a directional antenna.
  3. The AP is an outdoor access point.
  4. The AP is configured in Mesh mode
Correct answer: B
Explanation:
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.Reference: https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/wlan-rf/rf-fundamentals.htmhttps://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/wlan-rf/antennas.htm

Question 7
Your customer has asked you to assign a switch management role for a new user The customer requires the user role to only have Web Ul access to the System > Log page and only have access to the GET method for REST API for the /logs/event resource
Which default AOS-CX user role meets these requirements?
  1. administrators
  2. auditors
  3. sysops
  4. operators
Correct answer: A
Explanation:
The auditors role is the default AOS-CX user role that meets the requirements of having Web UI access to the System > Log page and having access to the GET method for REST API for the /logs/event resource. The auditors role has a level of 1 and allows read-only access to most commands except those related to security or passwords. It also allows access to the Web UI and REST API with limited permissions. The other options are incorrect because they either have higher levels of access or do not allow access to the Web UI or REST API.Reference: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch01.htmlhttps://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch04.html

Question 8
You are configuring Policy Based Routing (PBR) for a subnet that will be used to test a new default route for your network Traffic originating from 10.2.250.0/24 should use a new default route to 10.1.1.253. Other non-default routes for this subnet should not be affected by this change.
What are two parts of the solution for these requirements? (Select two.)
  1.  
  2.  
  3.  
  4.  
  5.  
Correct answer: CE
Explanation:
Two parts of the solution for these requirements are Option C and Option E.Option C is a part of the solution because it defines a policy-based routing action list named route_test, which specifies the next hop IP address as 10.1.1.253 for the matching traffic. This is the new default route that the user wants to use for the subnet 10.2.250.0/24. The interface null parameter indicates that the traffic will be routed to the next hop without using a specific interface1.Option E is a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 250, which has an IP address of 10.2.250.1/24. This is the subnet that the user wants to test the new default route for. The apply policy command enables policy-based routing on the interface and associates it with the action list2.Option A is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify the next hop IP address as 10.1.1.253, which is the new default route that the user wants to use. Instead, it specifies a next hop IP address of 10.1.1.254, which is different from the requirement.Option B is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify any next hop IP address at all, which is necessary for policy-based routing to work. Instead, it specifies an interface null parameter without any IP address, which is invalid.Option D is not a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 200, which has an IP address of 10.2.200.1/24. This is not the subnet that the user wants to test the new default route for, but a different subnet that should not be affected by this change.

Question 9
Refer to the exhibit.
   
With Core-1. what is the default value for config-revision?
  1. 0
  2. 1
  3. 1-0
  4. 0. 0
Correct answer: A
Explanation:
The default value for config-revision on Core-1 is 0. Config-revision is a parameter that indicates the configuration version of a VSX pair. It is used to synchronize the configuration between the VSX peers and to detect any configuration mismatch. The config-revision value is set to 0 by default on both VSX peers and is incremented by 1 every time a configuration change is made on either peer. The other options are incorrect because they do not reflect the default value of config-revision.Reference: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch07.html https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch02.html

Question 10
What are the requirements to ensure that WMM is working effectively'? (Select two)
  1. The APs and the controller are Wi-Fi CERTIFIED for WMM which is enabled
  2. All APs need to be from the AP-5xx series and AP-6xx series which are Wi-Fi CERTIFIED 6.
  3. The Client must be Wi-Fi CERTIFIED for WMM and configured for WMM marking.
  4. The Aruba AOS10 APs installed have to be converted to controlled mode
  5. The AP needs to be connected via a tagged VLAN to the wired port
Correct answer: AC
Explanation:
These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories:voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work.Reference: https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/wlan-qos/wmm.htm https://www.wi-fi.org/discover-wi-fi/wi-fi-certified-wmm
