What is Subnet Mask?
What are the two types of hierarchy domains that DNS servers use called?
What are Top-level domains (TLD) and Second-level domains (SLD)?
What term describes the undesirable situation in a network where data packets continuously circulate among switches, causing network congestion and performance degradation?
What are "Switching Loops"?
A cloud based service where the vendor provides the entire solution. This includes the operating system, infrastructure software, and the application.
What is SaaS?
What software category aids in security logging and alerting, enables the consolidation of data from multiple sources into a single platform, and facilitates the correlation of events or data points to assess risk?
What is SIEM, Security Information and Event Management?
What is an IP address assigned to a router that forwards remote traffic from its local subnet to remote networks?
What is Default Gateway?
What is the FQDN for the web server "www.example.com" if it resides in the "sales" subdomain of the "example.com" domain?
What is "www.sales.example.com"?
What CLI command will count the hops between the starting point and expected packet destination on Windows and macOS?
What is "tracert" on Windows and "traceroute" on macOS?
A cloud based service where the vendor provides the hardware platform or data center and the software running on the platform. The provider gives programmers all the tools they need to deploy, administer, and maintain a Web application.
What is PaaS?
What term encompasses utilities like packet sniffer, packet analyzer, protocol analyzer, and network analyzer, despite their differences, due to their shared capability of analyzing network traffic, and what caution should users heed when relying on the name of such tools?
What is "Network Analysis Tools"?

What is 62 usable IP addresses?
What process does DHCP use?
DORA: Discover, Offer, Request, Acknowledge
What term describes the process in networking where routers reach a mutual agreement on the best routes and network topology changes following a topology change event?
What is "Convergence"?
What contractual agreements outline the responsibilities of both the cloud service provider and the customer regarding security measures and protection of services, applications, and data in the cloud, including guarding against issues such as abusive usage, insecure APIs, insider threats, and unauthorized access between tenants?
What is a SLA, service level agreement?
What IT policy allows employees to utilize their personal mobile devices for corporate purposes, including the installation of company applications and corporate email accounts, necessitating stringent measures to segregate personal data from corporate data?

What is MX, Mail Exchange?
What type of routing protocols utilize a detailed understanding of network topology to calculate the shortest path to a destination, and what are the three tables they create?
What are "Link State Protocols"?
What is the hypervisor called when it runs directly on the host's hardware to control the hardware and manage guest operations?
What is a Type 1, bare metal, or native hypervisor?
This file format, commonly used for packet capture and analysis, allows network administrators to inspect network traffic for troubleshooting, security analysis, and performance monitoring.
