Which is a correct description of a stage in the Lockheed Martin kill chain?
- A. In the reconnaissance stage, the hacker assesses the impact of the attack and how much information was exfilltrated.
- B. In the delivery stage, malware collects valuable data and delivers or exfilltrated it to the hacker.
- C. In the exploitation and installation phases, malware creates a backdoor into the infected system for the hacker.
- D. In the weaponization stage, which occurs after malware has been delivered to a system, the malware executes Its function.
Answer: C
Explanation:
The Lockheed Martin Cyber Kill Chain model describes the stages of a cyber attack. In the exploitation phase, the attacker uses vulnerabilities to gain access to the system. Following this, in the installation phase, the attacker installs a backdoor or other malicious software to ensure persistent access to the compromised system. This backdoor can then be used to control the system, steal data, or execute additional attacks.

NEW QUESTION # 49
You have been authorized to use containment to respond to rogue APs detected by ArubaOS Wireless Intrusion Prevention (WIP). What is a consideration for using tarpit containment versus traditional wireless containment?
- A. Tarpit containment forms associations with clients to enable more effective containment with fewer disassociation frames than traditional wireless containment.
- B. Tarpit containment does not require an RF Protect license to function, while traditional wireless containment does.
- C. Rather than target all clients connected to rogue APs, tarpit containment targets only authorized clients that are connected to a rogue AP, reducing the chance of negative effects on neighbors.
- D. Rather than function wirelessly, tarpit containment sends ARP frames over the wired network to poison rogue APs ARP tables and prevent them from transmitting on the wired network.
Answer: A
Explanation:
Tarpit containment is a method used in ArubaOS Wireless Intrusion Prevention (WIP) to contain rogue APs.
It differs from traditional wireless containment in several ways, particularly in how it interacts with clients and manages network resources.
Tarpit containment works by spoofing frames from an AP to confuse a client about its association. It forces the client to associate with a fake channel or BSSID, which is more efficient than rogue containment via repeated de-authorization requests. This method is designed to be less disruptive and more resource-efficient1.
Here's why the other options are not correct:
Option A is incorrect because tarpit containment does not involve sending ARP frames over the wired network. It operates wirelessly by creating a fake channel or BSSID.
Option B is incorrect because tarpit containment does not selectively target authorized clients; it affects all clients connected to the rogue AP.
Option C is incorrect because tarpit containment does require an RF Protect license to function2.
Therefore, Option D is the correct answer. Tarpit containment is more effective at keeping clients off the network with fewer disassociation frames than traditional wireless containment. It achieves this by forming associations with clients, which leads to a more efficient use of airtime and reduces the chance of negative effects on legitimate network users12.
NEW QUESTION # 50
From which solution can ClearPass Policy Manager (CPPM) receive detailed information about client device type OS and status?
- A. ClearPass OnGuard
- B. ClearPass Onboard
- C. ClearPass Access Tracker
- D. ClearPass Guest
Answer: A
Explanation:
ClearPass Policy Manager (CPPM) can receive detailed information about client device type, OS, and status from ClearPass OnGuard. ClearPass OnGuard is part of the ClearPass suite and provides posture assessment and endpoint health checks. It gathers detailed information on the status and security posture of devices trying to connect to the network, such as whether antivirus software is up to date, which operating system is running, and other details that characterize the device's compliance with the network's security policies.
References:
Aruba ClearPass product documentation that details the capabilities of ClearPass OnGuard.

NEW QUESTION # 51
How can ARP be used to launch attacks?
- A. A hacker can use ARP to claim ownership of a CA-signed certificate that actually belongs to another device.
- B. Hackers can use ARP to change their NIC's MAC address so they can impersonate legiti-mate users.
- C. A hacker can send gratuitous ARP messages with the default gateway IP to cause devices to redirect traffic to the hacker's MAC address.
- D. Hackers can exploit the fact that the port used for ARP must remain open and thereby gain remote access to another user's device.
Answer: C
Explanation:
ARP (Address Resolution Protocol) can indeed be exploited to conduct various types of attacks, most notably ARP spoofing/poisoning. Gratuitous ARP is a special kind of ARP message which is used by an IP node to announce or update its IP to MAC mapping to the entire network. A hacker can abuse this by sending out gratuitous ARP messages pretending to associate the IP address of the router (default gateway) with their own MAC address. This results in traffic that was supposed to go to the router being sent to the attacker instead, thus potentially enabling the attacker to intercept, modify, or block traffic.
NEW QUESTION # 52

- C. Generate the private key online, but the public key and CSR offline, to install the same certificate on multiple MCs.
- D. if you create the CSR and public/private Keypair offline, create a matching private key online on the MC.
Answer: A
NEW QUESTION # 53
Which endpoint classification capabilities do Aruba network infrastructure devices have on their own without ClearPass solutions?
- A. ArubaOS-CX switches can use a combination of active and passive methods to assign roles to clients.
- B. ArubaOS devices (controllers and lAPs) can use DHCP fingerprints to assign roles to clients.
- C. ArubaOS devices can use a combination of DHCP fingerprints, HTTP User-Agent strings, and Nmap to construct endpoint profiles.
- D. ArubaOS-Switches can use DHCP fingerprints to construct detailed endpoint profiles.
Answer: B
Explanation:
Without the integration of Aruba ClearPass or other advanced network access control solutions, ArubaOS devices (controllers and Instant APs) are able to use DHCP fingerprinting to assign roles to clients. This method allows the devices to identify the type of client devices connecting to the network based on the DHCP requests they send. While this is a more basic form of endpoint classification compared to the capabilities provided by ClearPass, it still enables some level of access control based on device type. This functionality and its limitations are described in Aruba's product documentation for ArubaOS devices, highlighting the benefits of integrating a full-featured solution like ClearPass for more granular and powerful endpoint classification capabilities.

NEW QUESTION # 58
Device A is contacting https://arubapedia.arubanetworks.com. The web server sends a certificate chain. What does the browser do as part of validating the web server certificate?
- A. It makes sure that the key in the certificate matches the key that DeviceA uses for HTTPS.
- B. It makes sure that the public key in the certificate matches DeviceA's private HTTPS key.
- C. It makes sure the certificate has a DNS SAN that matches arubapedia.arubanetworks.com
- D. It makes sure that the public key in the certificate matches a private key stored on DeviceA.
Answer: C
Explanation:
When a device like Device A contacts a secure website and receives a certificate chain from the server, the browser's primary task is to validate the web server's certificate to ensure it is trustworthy. Part of this validation includes checking that the certificate contains a DNS Subject Alternative Name (SAN) that matches the domain name of the website being accessed-in this case, arubapedia.arubanetworks.com. This ensures that the certificate was indeed issued to the entity operating the domain and helps prevent man-in-the-middle attacks where an invalid certificate could be presented by an attacker. The DNS SAN check is critical because it directly ties the digital certificate to the domain it secures, confirming the authenticity of the website to the user's browser.
