In advanced network management, how does SDN (Software-Defined Networking) change the approach to device monitoring?
- Centralized Control
- Increased Latency
- Device-specific Protocols
- Physical Network Isolation
SDN introduces centralized control, allowing for more efficient device monitoring and management by abstracting control from the physical devices.
Which protocol is commonly encapsulated within GRE tunnels to provide VPN services?
- IPsec
- MPLS
- L2TP
- PPTP
IPsec is commonly encapsulated within GRE tunnels to provide VPN services.
In SDN, what is the role of Network Function Virtualization (NFV)?
- NFV virtualizes network functions, such as firewalls and load balancers, allowing them to run as software instances on commodity hardware.
- NFV is responsible for physical connectivity in SDN, ensuring that network devices are properly connected.
- NFV is an obsolete concept in SDN, and its role has been replaced by more advanced technologies.
- NFV is only applicable in traditional, non-virtualized networking environments.
In SDN, NFV virtualizes network functions, enabling them to run as software instances on commodity hardware for increased flexibility.
How does DHCP Snooping enhance network security?
- Blocks all DHCP traffic
- Enables dynamic IP allocation
- Encrypts DHCP messages
- Filters unauthorized DHCP messages
DHCP Snooping enhances network security by filtering unauthorized DHCP messages, preventing malicious DHCP attacks such as DHCP spoofing and starvation.
In AAA, ________ determines what resources a user can access and what operations they can perform.
- Authentication
- Authorization
- Accounting
- All of the Above
In AAA, Authorization determines what resources a user can access and what operations they can perform.
In network scripting, _______ patterns are used to extract specific information from structured text like logs or configuration files.
- Regular Expression
- JSON
- XPath
- YAML
In network scripting, Regular Expression patterns are used to extract specific information from structured text like logs or configuration files.
SNMP operates in the ______ layer of the OSI model, providing a framework for managing devices in a network.
- Application
- Data Link
- Network
- Presentation
SNMP operates in the Application layer of the OSI model, providing a framework for managing devices in a network.
A network engineer needs to design a network that can efficiently handle varying types of traffic, such as voice, video, and data. What technology would be most suitable for such requirements?
- QoS (Quality of Service)
- VLAN (Virtual Local Area Network)
- MPLS
- Frame Relay
QoS (Quality of Service) technology is most suitable for designing a network that can efficiently handle varying types of traffic, ensuring the prioritization of voice, video, and data.
For a small network with a stable topology, which routing method is generally more cost-effective and simpler to manage?
- Default Routing
- Dynamic Routing
- Hybrid Routing
- Static Routing
Static routing is generally more cost-effective and simpler to manage for small networks with stable topologies as it involves manually configuring routes.
Which device is used to connect multiple devices within one local network, often used in homes and small businesses?
- Hub
- Modem
- Router
- Switch
A switch is used to connect multiple devices within one local network, commonly used in homes and small businesses.
