QUESTIONS WITH SOLUTIONS GRADED A+
◍ is a cloud computing model that delivers software applications over the
internet, on a subscription basis. Instead of installing and maintaining
software locally, users can access these applications through a web browser..
Answer: Software as a Service (SaaS)
◍ dig.
Answer: Dig (domain information groper) is a command used to query the
DNS name servers. It is helpful in troubleshooting DNS problems. It is also
used for lookups and will display answers from the query. It is a
replacement for nslookup.
◍ Brute force.
Answer: Method of trying all possible combinations to crack encryption
◍ a network configuration where each device (node) is connected directly to
two other devices, forming a circular pathway or ring. Data travels from one
device to the next in a unidirectional manner until it reaches its destination..
Answer: Ring Topology
◍ traceroute/tracert.
Answer: A TCP/IP troubleshooting utility that uses ICMP to trace the path
from one networked node to another, identifying all intermediate hops
between the two nodes. Traceroute is useful for determining router or subnet
connectivity problems. On Windows-based systems, the utility is known as
tracert.
◍ Public Cloud.
Answer: Hosted by companies like AWS, Azure, and GCP, offering
scalable, multi-tenant solutions in data centers
,◍ Deauth Attack.
Answer: Exploit that de-associates a device from a Wi-Fi network
◍ WAP.
Answer: Wireless Access Point used for network access
◍ Manages sessions or connections between applications on different devices.
Establishes, maintains, and terminates sessions and handles session
synchronization and dialog control. Network Operating System. NFS, SQL,
PPTP, NetBIOS, PAP, SCP (tunneling).
Answer: Session Layer
◍ VPN.
Answer: Virtual private network for secure remote server management
◍ nslookup.
Answer: Nslookup (name server lookup) displays information for displaying
DNS information and troubleshooting DNS problems. It is useful in
displaying names to IP address mappings.
◍ RADIUS.
Answer: Remote Authentication Dial-In User Service for validating
credentials
◍ Restore process.
Answer: Recovering data from a backup to its original state
◍ Counter Mode Cipher Block Chaining Message Authentication Code
Protocol.
Answer: CCMP, part of the AES encryption standard used in WPA2
◍ is a computing environment that integrates on-premises private cloud
infrastructure with public cloud services. This approach allows
organizations to benefit from the flexibility and scalability of public cloud
platforms while maintaining control over critical data and applications in a
private cloud..
Answer: Hybrid Cloud Deployment
, ◍ Corporate data center.
Answer: A facility where an organization's data is stored and managed
◍ a network configuration where each device (node) is connected to a single
central cable, known as the bus or backbone. Data sent from a device travels
along the bus in both directions and can be received by all other devices on
the network..
Answer: Bus Topology
◍ Data protection.
Answer: Ensuring the safety and integrity of data
◍ Multifactor Authentication (MFA).
Answer: Using multiple methods to verify identity, such as
username/password and token/device
◍ This is the topmost layer, where applications that use the network operate. It
includes protocols like HTTP, FTP, SMIP, IMAP, SMTP.
Answer: Application Layer
◍ Group permissions.
Answer: Assigning permissions to groups instead of individual user
accounts
◍ Network security.
Answer: Protecting servers from attacks and managing cloud-based servers
◍ is a cloud computing model that provides a platform allowing customers to
develop, run, and manage applications without the complexity of building
and maintaining the underlying infrastructure..
Answer: Platform as a Service (PaaS)
◍ a network configuration where each device (node) in the network is
connected directly to a central hub or switch, which acts as a conduit to
transmit data between devices. This central device manages and controls the
flow of data in the network..
Answer: Star Topology
