________ is a feature of VPNs that allows the creation of secure connections over a public network infrastructure.
- Tunneling
- Encryption
- Authentication
- Decryption
Tunneling is a feature of VPNs that allows the creation of secure connections over a public network infrastructure.
A company wants to migrate its data and applications to the cloud to improve scalability and reduce operational costs. Which type of cloud computing model should they consider?
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
- Function as a Service (FaaS)
For scalability and reduced operational costs, a Platform as a Service (PaaS) model is suitable as it provides a platform to develop, run, and manage applications without the complexity of infrastructure management.
A ________ topology is characterized by a central node to which all other nodes are connected, forming a layout resembling a star.
- Bus
- Mesh
- Ring
- Star
A Star topology is characterized by a central node to which all other nodes are connected, forming a layout resembling a star.
In what topology do data packets travel from node to node in a ring, with each node having the chance to transmit?
- Bus
- Mesh
- Ring
- Star
In a ring topology, data packets travel from node to node in a ring, with each node having the chance to transmit when it receives control.
Syslog uses what protocol for transmitting log messages in a plain text format?
- TCP
- UDP
- ICMP
- IP
Syslog uses the UDP (User Datagram Protocol) for transmitting log messages in a plain text format.
________ is a crucial skill for network engineers focusing on automation, enabling them to interact with various network devices and services.
- Python
- Java
- C++
- Ruby
Python is a crucial skill for network engineers focusing on automation, enabling them to interact with various network devices and services.
A company is expanding its network infrastructure and requires a setup that allows for easy scalability and centralized management. Which technology would best suit their needs?
- MPLS
- OSPF
- SD-WAN
- VLAN
SD-WAN (Software-Defined Wide Area Networking) would best suit the company's needs as it offers easy scalability and centralized management of network infrastructure.
In a network that requires both IPv4 and IPv6 support with the capability of load balancing over unequal paths, which routing protocol would be most suitable?
- BGP
- EIGRP
- OSPF
- RIPng
EIGRP (Enhanced Interior Gateway Routing Protocol) supports both IPv4 and IPv6, along with the capability of load balancing over unequal paths.
Which of the following is a common reason for using NAT in a network?
- Boosting wireless signal strength
- Conserving public IP addresses
- Enhancing data encryption
- Increasing network complexity
A common reason for using NAT is to conserve public IP addresses by allowing multiple devices in a private network to share a single public IP address.
For a company that needs a routing protocol to efficiently handle frequent network topology changes without causing significant traffic due to routing updates, what would be the best choice?
- BGP
- EIGRP
- OSPF
- RIP
OSPF (Open Shortest Path First) is a link-state routing protocol designed to efficiently handle frequent network topology changes without causing significant traffic due to routing updates.
