QUESTION: 1

What is a vulnerability of an unauthenticated Dime-Heliman exchange?

A hacker can replace the public values exchanged by the legitimate peers and launch an MITM attack.
A brute force attack can relatively quickly derive Diffie-Hellman private values if they are able to obtain public values
Diffie-Hellman with elliptic curve values is no longer considered secure in modem networks, based on NIST recommendations.
Participants must agree on a passphrase in advance, which can limit the usefulness of Diffie- Hell man in practical contexts.

Answer(s): A

Explanation:

The vulnerability of an unauthenticated Diffie-Hellman exchange, particularly when it comes to the risk of a man-in-the-middle (MITM) attack, is a significant concern. In this scenario, a hacker can intercept the public values exchanged between two legitimate parties and substitute them with their own. This allows the attacker to decrypt or manipulate the messages passing between the two original parties without them knowing. This answer is based on the fundamental principles of how Diffie-Hellman key exchange works and its vulnerabilities without authentication mechanisms. Reference materials from cryptographic textbooks and security protocols detail these vulnerabilities, such as those found in standards and publications by organizations like NIST.

QUESTION: 2

What is a difference between radius and TACACS+?

RADIUS combines the authentication and authorization process while TACACS+ separates them.
RADIUS uses TCP for Its connection protocol, while TACACS+ uses UDP tor its connection protocol.
RADIUS encrypts the complete packet, white TACACS+ only offers partial encryption.
RADIUS uses Attribute Value Pairs (AVPs) in its messages, while TACACS+ does not use them.

Answer(s): A

Explanation:

RADIUS and TACACS+ are both protocols used for networking authentication, but they handle the processes of authentication and authorization differently. RADIUS (Remote Authentication Dial-In User Service) combines authentication and authorization into a single process, whereas TACACS+ (Terminal Access Controller Access-Control System Plus) separates these processes. This separation in TACACS+ allows more flexible policy enforcement and better control over commands a user can execute. This difference is well-documented in various network security resources, including Cisco's technical documentation and security protocol manuals.

QUESTION: 6

Your ArubaoS solution has detected a rogue AP with Wireless intrusion Prevention (WIP).
Which information about the detected radio can best help you to locate the rogue device?

the match method
the detecting devices
the match type
the confidence level

Answer(s): B

Explanation:

When an ArubaOS solution detects a rogue AP with Wireless Intrusion Prevention (WIP), the most crucial information that can help locate the rogue device is the detecting devices. This is because the detecting devices can provide the physical location or the network topology context where the rogue AP has been detected1.
The detecting devices are typically the Air Monitors (AMs) or Access Points (APs) in the network that have identified the rogue AP's presence. These devices can provide information such as the signal strength and the direction from which the rogue AP's signals are being received. By triangulating this information from multiple detecting devices, it becomes possible to pinpoint the physical location of the rogue AP2.
Additionally, the detecting devices can log events and alerts that can be reviewed to understand the rogue AP's behavior, such as the channels it is operating on and the potential impact on the authorized wireless network1. This information is vital for network administrators to quickly and effectively respond to the threat posed by the rogue AP. In contrast, the match method (A) and match type © relate to how the rogue AP is classified and identified by the system, which is useful for classification but not for physical location. The confidence level (D) indicates the system's certainty in the classification but does not aid in locating the device2.

QUESTION: 8

What is a benefit or using network aliases in ArubaOS firewall policies?

You can associate a reputation score with the network alias to create rules that filler traffic based on reputation rather than IP.
You can use the aliases to translate client IP addresses to other IP addresses on the other side of the firewall
You can adjust the IP addresses in the aliases, and the rules using those aliases automatically update
You can use the aliases to conceal the true IP addresses of servers from potentially untrusted clients.

Answer(s): C

Explanation:

In ArubaOS firewall policies, using network aliases allows administrators to manage groups of IP addresses more efficiently. By associating multiple IPs with a single alias, any changes made to the alias (like adding or removing IP addresses) are automatically reflected in all firewall rules that reference that alias. This significantly simplifies the management of complex rulesets and ensures consistency across security policies, reducing administrative overhead and minimizing the risk of errors.

Reference:

This functionality is part of the ArubaOS firewall management features, designed to enhance the usability and flexibility of network security configurations in dynamic network environments.
