You are working on a network where the customer has a dedicated router with redundant Internet connections Tor outbound high-importance real-time audio streams from their datacenter
All of this traffic.
* originates from a single subnet
* uses a unique range of UDP ports
* is required to be routed to the dedicated router
All other traffic should route normally The SVI for the subnet containing the servers originating the traffic is located on the core routing switch in the datacenter.
What should be configured?
- A . Configure a new OSPF area including both the core routing switch and the dedicated router
- B . Configure a BGP link between the core routing switch and the dedicated router and route filtering.
- C . Configure Policy Based Routing (PBR) on the core routing switch for the VRF with the servers’ SVI
- D . Configure a dedicated VRF on the core routing switch and make the dedicated router the default route.
C
Explanation:
The reason is that PBR allows you to route packets based on policies that match certain criteria, such as source or destination IP addresses, ports, protocols, etc. PBR can also be used to set metrics, next-hop addresses, or tag traffic for different routes.
With the Aruba CX switch configuration, what is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation?
- A . Active Gateway
- B . Active-Active VRRP
- C . SVI with vsx-sync
- D . VRRP
A
Explanation:
Active Gateway is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation. Active Gateway is a feature that allows both VSX peers to act as active gateways for different subnets, eliminating the need for VRRP or other first-hop redundancy protocols. Active Gateway also provides fast failover and load balancing for L3 traffic across the VSX peers. The other options are incorrect because they are either not recommended or not supported by Aruba CX VSX.

- A . ClearPass OnBoard
- B . Windows Server PKl and a GPO
- C . Apple Configurator and a GPO
- D . ClearPass OnGuard
- E . Mobile Device Manager
A B
Explanation:
The reason is that ClearPass OnBoard is a tool that allows you to enroll Mac computers into a ClearPass Policy Manager site using an Apple MDM push certificate. This certificate can be obtained from Apple or from a third-party PKI provider.
Apple Configurator is a tool that allows you to configure and deploy Mac computers using a GPO. This tool can also be used to enroll Mac computers into a ClearPass Policy Manager site using an Apple MDM push certificate.
Which statement about Aruba ClearPass Policy Manager is correct?
- A . It is primarily used for device firmware management.
- B . It serves as a gateway for all network traffic.
- C . It provides network access control and policy management.
- D . It only supports wireless authentication protocols.
For the Aruba CX 6400 switch, what does virtual output queueing (VOQ) implement that is different from most typical campus switches?
- A . large ingress packet buffers
- B . large egress packet buffers
- C . per port ASICs
- D . VSX
When setting up an Aruba CX VSX pair, which information does the Inter-Switch Link Protocol configuration use in the configuration created?
- A . QSVI
- B . MAC tables
- C . UDLD
- D . RPVST+
B
Explanation:
UDLD (Unidirectional Link Detection) is the information that the Inter-Switch Link Protocol configuration uses in the configuration created for Aruba CX VSX pair inter-switch-link. UDLD is a protocol that detects unidirectional links between switches and prevents loops or black holes in the network. UDLD is enabled by default on all ports that are part of the inter-switch-link between VSX peers. The other options are incorrect because they are either not related to inter-switch-link or not supported by Aruba CX VSX.

You are are doing tests in your lab and with the following equipment specifications:
* AP1 has a radio that generates a 16 dBm signal.
* AP2 has a radio that generates a 13 dBm signal.
* AP1 has an antenna with a gain of 8 dBi.
* AP2 has an antenna with a gain of 12 dBi.
* The antenna cable for AP1 has a 4 dB loss.
* The antenna cable for AP2 has a 3 dB loss.
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for AP1?
- A . -9 dBm
- B . 20 dBm
- C . 40 dBm
- D . 15 dBm
B
Explanation:
The Equivalent Isotropic Radiated Power (EIRP) is the measured radiated power of an antenna in a specific direction. It is also called Equivalent Isotropic Radiated Power. It is the output power when a signal is concentrated into a smaller area by the Antenna. The EIRP can take into account the losses in transmission line, connectors and includes the gain of the antenna. It is represented in dB2.
The formula for EIRP is:
EIRP=PT−Lc+Ga where PT is the output power of the transmitter in dBm, Lc is the cable and connector loss in dB, and Ga is the antenna gain in dBi.
For AP1, the EIRP can be calculated as:
EIRP=16−4+8=20 dBm
Therefore, the answer B 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?
- A . Turn off the DHCP scope on the gateway, and set DNS correctly on the gateway to reach Aruba Activate
- B . Move the cable on the gateway from port G0/0V1 tc port GO 0.0
- C . Move the cable on the gateway to G0/0/1. and add the device’s MAC and Serial number in Central
- D . Factory default and reboot the gateway to restart the process.
your customer has asked you to assign a switch management role for a new user The customer requires the user role to View switch configuration information and have access to the PUT and POST meth0ds for REST API.
Which default AOS-CX user role meets these requirements?
- A . administrators
- B . auditors
- C . sysops
- D . helpdesk
C
Explanation:
The correct answer is C. sysops.
The sysops user role is a predefined role that allows users to view switch configuration information and have access to the PUT and POST methods for REST API. The sysops user role can also use the PATCH and DELETE methods for REST API, but not for all resources. The sysops user role is suitable for users who need to perform system operations on the switch, such as backup, restore, upgrade, or reboot.
According to the AOS-CX REST API Reference basics1, one of the predefined user roles is: sysops: Users with this role can view switch configuration information and have access to the PUT and POST methods for REST API. They can also use the PATCH and DELETE methods for REST API, but not for all resources. Users with this role can perform system operations on the switch, such as backup, restore, upgrade, or reboot.
The other options are incorrect because:
A) administrators: Users with this role have full access to all switch configuration information and all REST API methods. This role is more than what the customer requires.
B) auditors: Users with this role can only view switch configuration information and have access to the GET method for REST API. They cannot use the PUT and POST methods for REST API.
D) helpdesk: Users with this role can view switch configuration information and have access to the GET method for REST API. They can also use the PATCH method for REST API, but only for a limited set of resources. They cannot use the PUT and POST methods for REST API.
Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements. After the configuration was complete, it was noted that a user assigned with the auditors role did not have the appropriate level of access on the switch.
The user was not allowed to perform firmware upgrades and a privilege level of 15 was not assigned to their role .
Which default management role should have been assigned for the user?
- A . sysadmin
- B . sysops
- C . administrators
- D . config
C
Explanation:
In AOS-CX switches, when assigning management roles to users that need to perform firmware upgrades and require a privilege level of 15, the role with the highest privileges should be chosen.
The "administrators" role typically provides full management access, including the ability to perform firmware upgrades and configure the switch. This role is suitable for users who need to perform advanced management and configuration tasks.
Other roles such as "sysadmin", "sysops", and "config" may provide certain levels of access but may not necessarily include the ability to perform firmware upgrades or have privilege level 15.
