laaS (Infrastructure as a Service) is a cloud model that provides clients with servers, storage, and networks but nothing else. It allows clients to have more control and flexibility over the configuration and management of their infrastructure resources, but also requires them to install and maintain their own operating systems, applications, etc.

Push notifications are a type of technology that allows an application or a service to send messages or alerts to a user's device without requiring the user to open the application or the service. They can be used for multi-factor authentication (MFA) by sending a prompt or a code to the user's device that the user has to approve or enter to verify their identity. They can be non-disruptive and user friendly because they do not require the user to remember or type anything, and they can be delivered instantly and securely.

NAT (Network Address Translation) is a technique that allows a router to translate private IP addresses into public IP addresses and vice versa. It can preserve the use of public IP addresses assigned to equipment on the core router by allowing multiple devices to share a single public IP address. TLSv2 (Transport Layer Security version 2) is a cryptographic protocol that provides secure communication over the internet. It can enable "in transport" encryption protection to the web server with the strongest ciphers by encrypting the data transmitted between the web server and the clients using advanced algorithms and key exchange methods.

The router is experiencing a resource exhaustion issue. The output from the command indicates that the CPU is consistently busy, with a 1-second average of 99 percent busy and a 1-minute average of 83 percent busy. This indicates that the router is struggling to keep up with the demands placed on it, potentially due to a high volume of traffic or other factors. As a result, web pages are experiencing long load times. This is an example of resource exhaustion, where the router's resources are being overwhelmed and are unable to meet the demands placed on them. A DDoS attack, memory leak, or buffer overflow would not typically cause the symptoms described in the scenario.

Tor (The Onion Router) is a network and a software that enables anonymous communication over the internet. It routes the traffic through multiple relays and encrypts it at each layer, making it difficult to trace or monitor. It can access the dark web, which is a part of the internet that is hidden from conventional search engines and requires special software or configurations to access

This command creates an inbound access list that denies any IP traffic from the source IP address of 10.1.4.9/32 to any destination IP address (0.0.0.0/0). It blocks the originating source of malicious traffic from accessing the organization's network.

SaaS (Software as a Service) is a cloud model that provides clients with applications and software that are hosted and managed by a cloud provider over the internet. It can move email services to the cloud by allowing clients to access and use email applications without installing or maintaining them on their own devices or servers

Mobile device management (MDM) is a solution that allows an organization to manage, monitor, and secure mobile devices that are used by employees for work purposes. It can protect company information on user devices by enforcing policies and controls such as encryption, password, remote wipe, etc., and detecting and preventing unauthorized access or data leakage.
