Authentic Paloalto Networks Certification Exam Practitioner Questions Answers

According to the NIST definition, cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction1. One of the essential characteristics of cloud computing is on-demand self-service, which means that users can request and obtain computing resources as needed, without requiring human intervention from the service provider2. On-demand network services are an example of this characteristic, as they allow users to access network resources such as bandwidth, routing, firewall, or load balancing, on demand and in a scalable manner3. References:

DNS tunneling is an attack technique where data packets are disguised as DNS queries and sent to a remote server. That server, often under the attacker's control, responds with additional data or instructions, effectively creating a covert command-and-control (C2) channel over DNS.

HTTPS is a protocol that encrypts and secures the communication between web browsers and servers. HTTPS uses SSL or TLS certificates to establish a secure connection and prevent unauthorized access or tampering of data. HTTPS typically uses port 443, which is the default port for HTTPS connections. Port 443 is different from port 80, which is the default port for HTTP connections. HTTP is an unencrypted and insecure protocol that can expose sensitive information or allow malicious attacks. Port 443 is also different from port 5050, which is a common port for some applications or services, such as Yahoo Messenger or SIP. Port 5050 is not associated with HTTPS and does not provide any encryption or security. Port 443 is also different from port 25, which is the default port for SMTP, the protocol used for sending and receiving emails. Port 25 is not associated with HTTPS and does not encrypt the email content or headers. References:
