Cisco® 350-701 Exam Practice Questions (P. 1)

GPT-4o - Answer

Southbound APIs in an SDN architecture primarily facilitate direct communication between the SDN controller and network elements such as switches and routers. This setup allows the SDN controller to distribute commands and configurations across the network while simultaneously receiving status updates and other pertinent information from network devices. This communication is crucial for the SDN controller's ability to centrally manage and dynamically adjust network operations based on real-time conditions.

GPT-4o - Answer

Northbound APIs primarily function to facilitate communication between the SDN controller and the applications driving the management solutions over a network. These APIs are vital for allowing software-level requests to manipulate network behaviors, providing a comprehensive interface for the orchestration and automation of network resources in alignment with application needs. While it's a close argument whether the correct configuration involves the cloud, typically the direct communication is between the SDN controller and the management applications directly interfacing with it, not the abstract cloud infrastructure.

GPT-4o - Answer

Intent-based APIs are a notable feature of Cisco DNA Center's open platform capabilities, allowing for extended programmability and interaction with third-party applications. These APIs facilitate the translation of business intent into network policies and ensure network configurations are consistently aligned with business requirements, thus supporting a highly adaptive and responsive network infrastructure.

GPT-4o - Answer

DDoS attacks, which stand for Distributed Denial of Service, effectively utilize botnets - networks of compromised computers controlled by attackers. These botnets are orchestrated to flood targeted systems with overwhelming traffic, causing disruptions by exceeding the targeted system's capacity to handle user requests. This method significantly amplifies the attack's scale compared to individual attacks, making botnets a preferred tool for such extensive disruptions. Thus, DDoS is indeed the correct answer associated with the use of botnets in cyberattacks.

GPT-4o - Answer

Cross-site scripting (XSS) attacks often employ various forms of alternate encoding, such as hexadecimal representation, to obfuscate malicious script elements embedded in web pages. This encoding helps disguise the nature of the attack, making it challenging for both users and security systems to recognize the malicious content. As the attack leverages encoded scripts activated when a user interacts with compromised elements (e.g., clicking a link), understanding and identifying these encoding strategies are crucial in maintaining web security. This method is a hallmark of XSS attacks, where attackers aim to bypass conventional detection mechanisms effectively.

GPT-4o - Answer

Spear phishing, in contrast to deceptive phishing, is highly targeted. While general phishing campaigns might cast a wide net, attempting to fool as many people as possible, spear phishing zeros in on specific individuals. This targeted approach not only increases the likelihood of success but also allows attackers to tailor their methods and messages based on the personal or professional information of the target, adding a layer of authenticity and urgency to their fraudulent communications. This precision in targeting is what makes spear phishing particularly dangerous and effective.
