The Aruba Certified Campus Access Professional Exam (HPE7-A01)

This is because Best Effort traffic is all other kinds of non-detrimental traffic that are not sensitive to Quality of Service metrics (jitter, packet loss, latency).  A typical example would be peer-to-peer and email applications 2 .  Background traffic is a type of traffic that is used for system maintenance or backup purposes and does not affect the performance or availability of the network 3 .

Therefore, Best Effort traffic has a higher priority than Background traffic in terms of network resources allocation and management.

The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 17 dBm.

EIRP is the measured radiated power of an antenna in a specific direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It can also take into account the losses in transmission line, connectors, and other components. The formula for EIRP is:

EIRP = P + G - L

where P is the output power of the radio, G is the gain of the antenna, and L is the loss of the cable and connectors.

For AP1, we have:

P = 10 dBm G = 9 dBi L = 2 dB

Therefore,

EIRP = 10 + 9 - 2 EIRP = 17 dBm

The persona role option that should be selected to deploy a Gateway and take advantage of all the SD-WAN features is A. ArubaOS 10 Branch.

ArubaOS 10 Branch is a persona that enables the Gateway to provide both LAN and WAN functionality for branch networks. The Gateway can act as a wireless controller, a router, a firewall, and an SD-WAN device. The SD-WAN features include route and tunnel orchestration, dynamic path steering, forward error correction, SaaS traffic optimization, SASE orchestration, and more 1 .

The other options are incorrect because:

B. ArubaOS 10 VPN Concentrator: This is a persona that enables the Gateway to act as a VPN concentrator for remote access or site-to-site VPN connections. It does not provide SD-WAN features 2 .

C. ArubaOS 10 Wireless: This is a persona that enables the Gateway to act as a wireless controller for campus networks. It does not provide SD-WAN features 3 .

D. ArubaOS 10 Mobility: This is a persona that enables the Gateway to act as a mobility controller for campus networks. It does not provide SD-WAN features.

The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.

WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication. OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central 1 .

According to the Aruba document Configuring WLAN Settings for an SSID Profile , one of the steps to configure a WPA3 SSID is:

Select the Security Level from the drop-down list. The following options are available:

WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.

WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.

WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and encryption, as defined by the Counter with CBC-MAC (CCM) mode.

WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.

The other options are incorrect because:

A. WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company’s use case.

B. WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company’s use case.

D. WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company’s use case.

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.

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

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 dB 2 . 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.

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.

This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.
