The MPO (Multi-fiber Push On) connector is designed to handle multiple fiber strands in a single connector, and it is commonly used with high-density transceivers like QSFP (Quad Small Form-factor Pluggable).

QSFP can support up to four channels (hence " quad " ), and MPO connectors can interface multiple fibers (e.g., 8, 12, 24), making them ideal for 40Gbps or 100Gbps deployments.

RJ45 (A) is used for Ethernet over copper.

ST (B) and LC (C) are single-fiber connectors — they don ' t support the multi-fiber needs of QSFP setups.

✅ Therefore, MPO is the correct connector type for this use case.

TLS (Transport Layer Security) is the protocol that provides encryption in transit for HTTPS. It ensures data is encrypted between the client (browser) and the web server, protecting it from interception or tampering.

A. SSH is used for secure terminal access, not HTTPS.

C. SCADA refers to control systems, not encryption protocols.

D. RADIUS is an authentication protocol, not for encrypting HTTPS traffic.

Direct Connect refers to a dedicated network connection between an on-premises network and a cloud service provider (such as AWS Direct Connect). This link bypasses the public internet, providing a more reliable and higher-bandwidth connection. It may not inherently include encryption because it relies on the security measures of the dedicated physical connection itself. In contrast, other options like VPN typically involve encryption as they traverse the public internet.

Multitenancy is a cloud computing architecture where a single instance of software serves multiple customers or tenants. Each tenant ' s data is isolated and remains invisible to other tenants. Hosting a company application in the cloud to be available for both internal and third-party users fits this concept, as it allows shared resources and infrastructure while maintaining data separation and security.
