Networking protocols from HTTPS to SFTP
Classifies the protocols Mule applications use (HTTP and HTTPS for requests, FTP, FTPS and SFTP for files, TCP, UDP and WebSockets for sockets, JMS and VM for queues), shows where TLS fits, and explains why load balancers help socket traffic but not file polling.
Classify and describe common networking protocols used in system communication.
~6 min read · 4 practice questions ·
What the exam expects
- Classify a protocol as request-response (HTTP, HTTPS), file transfer (FTP, FTPS, SFTP), socket-level (TCP, UDP, WebSockets) or messaging (JMS, VM queues).
- Explain what TLS adds and which protocol to pick when traffic must be encrypted in transit.
- Choose the file transfer connector that matches what a remote server accepts.
- Explain why a load balancer spreads socket traffic but does not protect file-based transports.
Key terms:
- HTTPS: HTTP secured with TLS.
- TLS: a cryptographic protocol that provides communications security: key exchange, encryption and message integrity.
- File-based transport: a protocol that moves files between systems, such as File, FTP or SFTP.
- Socket-based endpoint: an inbound endpoint that receives connections directly, such as TCP or HTTP.
- Message queue: a destination that decouples sender and receiver, such as a JMS queue or a VM queue.
Key facts
