ARUBA A41 EXAM - ARUBA
CERTIFIED SWITCH ASSOCIATE
(ACSA) 2025 QUESTIONS AND
ANSWERS
What are the console settings for out-of-band (OOB) - ....ANSWER ...-The
switches use default settings for the terminal emulation
software:
•9600 bps
•8 data bits
•No parity
•1 stop bit
•No flow control
Switch modules come in two forms. Which switch forms supports port name "a39"? -
....ANSWER ...-Module Switch come in fix and module. Modular switches support
alphanumeric naming i.e. interface <slot_letter><1-24>
What aos command will allow you to configure ports 1, and 4 thru 9? -
....ANSWER ...-switch(config#) interface 1,4-9

,What command will Access the enable - ....ANSWER ...-context enable
What command will Access the global configuration - ....ANSWER ...-config
A user must prove who they are - ....ANSWER ...-authentication
user is allowed by RADIUS server policy to obtain network access -
....ANSWER ...-authorization
switch submits information about the user connection - ....ANSWER ...-
accounting
when does authentication start? - ....ANSWER ...-as soon as the connection
between the switch port and the client comes up
Both sides of (switch & client) connection control the port; disable by default and based
on authentication "state" - ....ANSWER ...-controlled port
Always active port; can only carry EAP packets to traverse for proper authentication -
....ANSWER ...-uncontrolled port
What are the roles in an AAA process? - ....ANSWER ...-Supplicant, Authenticator,
and Authentication server
can prove if users credentials are correct, validate if connecting at the proper time and
location - ....ANSWER ...-authentication server
opposing side of the client's connection; usually the switch and role to start
authentication with client - ....ANSWER ...-authenticator

,what are the requirements for 802.1x operations? - ....ANSWER ...-Client 802.1x
supplicant, 802.1x supporting device (i.e. switch), and 802.1x server supporting EAP-
RADIUS.
how does the switch aid in the supplicant/authentication server exchange -
....ANSWER ...-the switch encapsultes the supplicant's "EAP Request" messages
in RADIUS Access-Request messages, then sends to server
Aruba supports several EAP methods. Which is the most secure? - ....ANSWER ...-
EAP-Transport Layer Protocol (EAP-TLS)
What material is required to use EAP/TLS - ....ANSWER ...-digital certificate and
CA infrastructure to support cert creations.
What EAP method are supported by Aruba switching - ....ANSWER ...-EAP-TLS,
PEAP, and EAP-Tunneled TLS
What method provides security similar to EAP-TLS, without the use of digital certifcates
- ....ANSWER ...-PEAP and EAP-Tunneled TLS; PEAP created by Cisco,
Microsoft, and RSA Security).
What command will Access the enable - ....ANSWER ...-context enable
What command will Access the global configuration - ....ANSWER ...-configure
terminal
What's behavior for AOS-Switches with default settings and no password for local
authentication - ....ANSWER ...-If no password is configured, AOS-switch does not
perform any authentication
...©️ 2025, ALL RIGHTS RESERVED 3
, What three access types to CLI? - ....ANSWER ...-console, telnet, and SSH
(possible fourth is Web via http/https
What level is the user prompted to authenticate - ....ANSWER ...-Login Level
What level the user is prompted to authenticate when moving from basic mode to enable
mode
and, after successful authentication, receives manager rights. - ....ANSWER ...-
Enable Level
What BGP command ensure that the routers have routes to each peers loopback
interface - ....ANSWER ...-neighbor <ipv4-addr> ebgp-multihop [2-255]
BGP neighbors establish a TCP session on port ____ - ....ANSWER ...-Port 179
A network administrator is configuring a multicast routing solution. Potential
multicast receivers are on VLAN 5. What must the administrator enable on this VLAN? -
....ANSWER ...-PIM-DM and IGMP
What is one advantage of PIM-DM as compared to PIM-SM? - ....ANSWER ...-
PIM-DM tends to be simpler to set up.
When do PIM-SM receivers join the SPT tree? - ....ANSWER ...-At the reception of
a multicast stream, RP and other routers join SPT. Then, DR (gateway) for source starts
forward traffic in the SPT
Who is the PIM-SM designated router (DR)? - ....ANSWER ...-Based on the
source, The default router for the source's subnet receives the traffic. This default router
is called the DR.
