In the context of IPSec, what is meant by the term 'Security Association'?
- A biometric authentication method used in IPSec VPNs.
- A set of security parameters agreed upon by two IPSec peers for secure communication.
- The process of securing IPSec keys during transmission.
- A hardware device used to manage IPSec tunnels.
In IPSec, a Security Association (SA) is a set of security parameters agreed upon by two peers for secure communication, including algorithms, keys, and other attributes.
________ 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.
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.
A company is expanding its network infrastructure to support IPv6. What should be considered for efficient IPv6 routing and address allocation?
- Stateless Address Autoconfiguration (SLAAC)
- Network Address Translation (NAT)
- Dynamic Host Configuration Protocol (DHCPv6)
- Subnetting
For efficient IPv6 routing and address allocation, Stateless Address Autoconfiguration (SLAAC) is a key consideration. SLAAC allows devices to configure their IPv6 addresses automatically.
In a newly configured network with several switches, the network engineer needs to ensure a specific switch becomes the root bridge in STP. What configuration change is needed?
- Changing MAC Address
- Enabling PortFast
- Increasing Switch Priority
- Lowering Switch Priority
To ensure a specific switch becomes the root bridge in STP, the network engineer should increase the switch priority for that particular switch.
In home networking, which cable type is typically used to connect a modem to a router for internet access?
- Coaxial Cable
- Fiber Optic Cable
- HDMI Cable
- Twisted Pair
Coaxial cables are typically used in home networking to connect a modem to a router for internet access.
