Question 1

What does a wireless client do first when its countdown timer reaches zero and it receives a Transmit Opportunity (TXOP)?

AIt immediately sends its Data Frames and receives an ACK from the AP.

BIt sends a CTS-to-self announcement to the ESP gateway.

CIt sends a CTS-to-self announcement to the AP and all other clients.

DIt sends a reassociation request frame to the AP and sends its Data Frames.

Answer : A

When a wireless client's countdown timer (also known as a backoff timer) reaches zero during contention-based access periods, and it receives a Transmit Opportunity (TXOP), it has the right to transmit its data frames on the medium. After sending the data frames, it expects an acknowledgment (ACK) from the Access Point (AP) to ensure the frames were received successfully.

Question 2

A hacker has altered a user's 3-Way Handshake in order to gain access to their session.

Which security mechanism would intelligently deny this traffic?

AOut-of-band management (00BM)

BStateless firewall

CAccess Control List (ACL)

DStateful firewall

Answer : D

A stateful firewall would intelligently deny traffic from a hacker attempting to alter a user's 3-Way Handshake to gain access to their session. Stateful firewalls keep track of the state of active connections and can recognize if an incoming packet is part of an established session. This allows them to detect and block unauthorized access attempts that do not match the known state of a connection.

Question 3

What does the status of "ALFOE" mean when checking LACP with "show lacp interfaces'"?

AThe interface on the local switch is configured as static-LAG

BLACP is not configured on the peer side

CLACP is in a synchronizing process

DLACP is working fine with no problems

Answer : B

When checking the status of LACP (Link Aggregation Control Protocol) with the command 'show lacp interfaces,' various flags indicate the state of the LACP negotiation. 'ALFOE' indicates different states for each letter: A (Activity), L (Link), F (Aggregation), O (Synchronization), and E (Collecting). In this context, the O flag is particularly of interest. If the O flag is not set (meaning the synchronization is not achieved), it typically suggests that LACP is not configured or not functioning correctly on the peer side, hence the link is not operational as part of an LACP channel.

Question 4

A network technician has successfully connected to the employee SSID via 802 1X Which RADIUS message should you look for to ensure a successful connection?

AAuthorized

BAccess-Accept

CSuccess

DAuthenticated

Answer : B

The RADIUS message that you should look for to ensure a successful connection via 802.1X is Access-Accept. This message indicates that the RADIUS server has authenticated and authorized the supplicant (the device that wants to access the network) and has granted it access to the network resources. The Access-Accept message may also contain additional attributes such as VLAN ID, session timeout, or filter ID that specify how the authenticator (the device that controls access to the network, such as a switch) should treat the supplicant's traffic.

The other options are not RADIUS messages because:

Authorized: This is not a RADIUS message, but a state that indicates that a port on an authenticator is allowed to pass traffic from a supplicant after successful authentication and authorization.

Success: This is not a RADIUS message, but a status that indicates that an EAP Extensible Authentication Protocol (EAP) is an authentication framework that provides support for multiple authentication methods, such as passwords, certificates, tokens, or biometrics. EAP is used in wireless networks and point-to-point connections to provide secure authentication between a supplicant (a device that wants to access the network) and an authentication server (a device that verifies the credentials of the supplicant). exchange has completed successfully between a supplicant and an authentication server.

Authenticated: This is not a RADIUS message, but a state that indicates that a port on an authenticator has received an EAP-Success message from an authentication server after successful authentication of a supplicant.

Question 5

Describe the purpose of the administrative distance

ARoutes teamed via external BGP have a higher administrative distance than routes learned via OSPF

BThe administrative distance is used as a trust rating For route entries

CThe administrative distance for a static route is 10

DThe higher administrative distance is preferred

Answer : B

The administrative distance is used as a trust rating for route entries (B). It is a metric used by routers to select the best path when there are two or more different routes to the same destination from two different routing protocols. The lower the administrative distance value, the more trustworthy the source of the route. For example, a directly connected network has an administrative distance of 0 because it is the most trusted source of routing information. In contrast, routes learned from different routing protocols have higher administrative distances, reflecting their relative trustworthiness.

Question 6

A network technician is testing a new SSID for a branch office. They are able to connect, get an IP address, and resolve DNS names. However, they are not able to browse the internet.

On the existing SSID at the branch, connectivity to the internet works as expected on the same VLAN as the new SSID. The wireless client should have received a new role to allow internet access.

What should the network technician verify to ensure both SSIDs function in a similar way?

AVerify each SSID's authentication and encryption parameters are enabled and the same.

BVerify that the implicit 'deny all' is the last entry in the firewall policies.

CVerify the new SSID is broadcasting on all the APs at the branch office.

DVerify the firewall policies assigned, making sure the rules are correct and ordered properly.

Answer : D

When a network technician encounters an issue where a new SSID does not allow internet access despite successful connectivity and DNS resolution, they should verify the firewall policies associated with the new SSID. The firewall policies must include rules that permit traffic to and from the internet and should be correctly ordered to ensure that they are applied as intended. Since the existing SSID functions correctly, comparing the firewall rules between the two can be a useful method of troubleshooting.

Question 7

You need to troubleshoot an Aruba CX 6300F switch that fails to boot correctly. Select the option that allows you to access the switch and see the boot options available for OS images and ServiceOS.

AUSB-C console port

BRJ-45 console port

CUSB-A console port

DOmgmt port using SSH

Answer : A

To troubleshoot an Aruba CX 6300F switch that is failing to boot correctly, you would typically use the USB-C console port. This port allows you to connect to the switch directly with a console cable and access the boot loader menu, where you can see the available OS images and the ServiceOS for recovery and troubleshooting purposes.
