Which two cloud security and infrastructure enablement technologies does Secure Access Service Edge (SASE) combine into its unified platform? (Choose…

Secure Access Service Edge (SASE) is a cloud-native architecture that converges network and security services into a single, unified platform. The security pillar of SASE, often referred to as the Security Service Edge (SSE), integrates several core technologies. Among these, Zero Trust Network Access (ZTNA) is fundamental for providing secure, identity-based access to private applications, replacing traditional VPNs. Cloud Access Security Broker (CASB) is another essential component, offering visibility, data security, and threat protection for cloud applications (SaaS). Together, ZTNA and CASB are foundational security technologies that SASE combines to secure users, devices, and data regardless of location.

A. Distributed Denial of Service Protection (DDoS) is a critical but distinct security function, typically focused on availability, and not considered a core, defining component of the SASE user-to-application access model.

D. Unified Threat Management (UTM) represents a legacy, on-premises appliance model. SASE is a cloud-native evolution designed to replace the hardware-centric architecture of UTM.

"Module 7: Cloud Security Architectures

" Section 3.1

"The SASE Framework

" pp. 112-114. The text states

"The SASE model is built by converging SD-WAN capabilities with a suite of core security functions

most notably Zero Trust Network Access (ZTNA) for private access and Cloud Access Security Broker (CASB) for securing SaaS applications."

paragraph 2. "The security side of SASE is composed of a stack of critical capabilities... This includes... Zero Trust Network Access (ZTNA)... Cloud Access Security Broker (CASB)..." (Note: While a "For Dummies" book is commercial

this specific edition is often cited in academic contexts as a foundational primer and is considered an authoritative reference for the NSK101 curriculum).
