Which of the following IP address ranges is reserved for private networks and cannot be routed on the internet?
A 172.16.0.0/12
B 203.0.113.0/24
C 10.0.0.0/8
D 192.0.0.0/24
The 10.0.0.0/8 IP address range is part of the private address space defined by RFC 1918. It is used within local networks and cannot be routed over the public internet without the use of NAT (Network Address Translation).
Which of the following protocols is responsible for dynamically assigning IP addresses to devices in a network?
A DHCP
B HTTP
C DNS
D FTP
DHCP (Dynamic Host Configuration Protocol) is responsible for automatically assigning IP addresses to devices in a network. It simplifies network configuration by dynamically providing unique IP addresses to devices as they join the network.
Which process is used to divide an IP network into smaller, manageable sub networks?
A Routing
B Subnetting
C Supernetting
D NAT
Subnetting is the process of dividing a larger network into smaller sub networks, or subnets. This allows for better management of IP addresses, improved network performance, and easier isolation of traffic within a network.
Which of the following is used to resolve a domain name to an IP address in a network?
A ARP
B DHCP
C DNS
D NAT
DNS (Domain Name System) is responsible for translating domain names (e.g., www.example.com) into IP addresses, allowing devices to find and connect to the appropriate resources on the internet or a private network.
What does the term “supernetting” refer to in computer networking?
A Combining multiple networks
B Encrypting network traffic
C Dividing a network into subnets
D Assigning dynamic IP addresses
Supernetting involves combining multiple IP networks into a larger network by reducing the network portion of the address. This helps in efficient utilization of IP address space and simplifies routing.
Which of the following is a feature of cloud networking that enables virtualized resources to be provisioned and managed over the internet?
A VPN
B VLAN
C SDN
D NAT
Software Defined Networking (SDN) is a key feature of cloud networking that allows for the central control of network resources via software. It enables the dynamic provisioning, management, and configuration of virtualized resources over the internet.
Which of the following is a private address range defined by RFC 1918 for use within a local network?
A 10.10.10.0/24
B 203.0.113.0/24
C 172.16.0.0/12
D 200.100.50.0/24
The range 172.16.0.0/12 is part of the private IP address space reserved by RFC 1918. These addresses are used within local networks and are not routable on the public internet.
What is the primary advantage of using subnetting in a network?
A Increased address space
B Faster data transfer
C Improved security
D Easier network management
Subnetting allows network administrators to divide large networks into smaller, manageable subnets. This simplifies network management, improves efficiency, and helps isolate traffic to enhance security and performance.
Which protocol is used to assign IP addresses dynamically and ensure devices receive appropriate network configurations?
A ARP
B DHCP
C TCP
D DNS
DHCP (Dynamic Host Configuration Protocol) dynamically assigns IP addresses to devices on a network, ensuring that each device receives the correct network configuration, including IP addresses, subnet masks, and gateway information.
What is the purpose of the IP subnet mask in network communication?
A Identify device type
B Encrypt data packets
C Route packets across networks
D Determine network boundaries
The IP subnet mask defines the network and host portions of an IP address. It helps routers and devices determine which part of the address identifies the network and which part identifies the device within that network.
Which of the following describes a cloud network model that uses a central server to manage resources and provides a single point of access for clients?
A Client server model
B Cloud computing
C Distributed model
D Peer to peer model
The client server model is commonly used in cloud networks, where clients (users or devices) request resources or services from a central server that manages and provides the required resources, often over the internet.
Which of the following is a benefit of cloud networking in terms of resource management?
A Limited scalability
B Reduced security
C Dynamic provisioning of resources
D Increased manual configuration
Cloud networking allows for the dynamic provisioning of resources based on demand. This means that network capacity, storage, and computing power can be adjusted in real time, providing flexibility and scalability for businesses.
What does DNS stand for in computer networking?
A Data Network Service
B Domain Name System
C Digital Network System
D Dynamic Network Service
DNS (Domain Name System) is the system used to resolve human readable domain names (such as www.example.com) into IP addresses. It is crucial for the functioning of the internet, allowing users to access websites using easy to remember names.
Which of the following is typically the first step in the process of subnetting?
A Determine the subnet mask
B Define the IP address range
C Calculate the number of hosts
D Convert binary to decimal
The first step in subnetting is determining the subnet mask, which helps define the network portion of the IP address and facilitates the division of a network into smaller subnets, allowing for efficient use of IP addresses.
Which of the following is a common use case for a VPN in cloud networking?
A Increasing bandwidth
B Managing network traffic
C Reducing latency
D Providing secure remote access
A VPN (Virtual Private Network) is commonly used in cloud networking to provide secure remote access to a network. It encrypts data traffic, ensuring privacy and protection while accessing resources over the internet from remote locations.
