The _______ field in the IPv4 header is used to limit the lifespan of a packet.
- Checksum
- Destination Address
- Source Address
- TTL (Time to Live)
The Time to Live (TTL) field in the IPv4 header is used to limit the lifespan of a packet by specifying the maximum number of hops the packet can take.
The ________ in SDN architecture is responsible for forwarding data packets based on the rules set by the controller.
- Data Plane
- Control Plane
- Management Plane
- Forwarding Plane
The Data Plane in SDN architecture is responsible for forwarding data packets based on the rules set by the controller.
In which WAN connection type is traffic directed through labeled paths, offering efficient and flexible data forwarding?
- MPLS
- Frame Relay
- DSL
- ISDN
In MPLS (Multiprotocol Label Switching), traffic is directed through labeled paths, providing efficient and flexible data forwarding.
________ is a standard for connecting high-speed networking and storage systems, using a type of cable that supports both copper and optical interfaces.
- Ethernet
- Fibre Channel
- Thunderbolt
- USB
Fibre Channel is a standard for connecting high-speed networking and storage systems, supporting both copper and optical interfaces.
In a large enterprise network, the network administrator is tasked with ensuring efficient management of VLAN configurations across all switches. What technology or protocol would be most beneficial in this scenario?
- HSRP (Hot Standby Router Protocol)
- SNMP
- STP (Spanning Tree Protocol)
- VTP (VLAN Trunking Protocol)
VTP (VLAN Trunking Protocol) is beneficial for efficient management of VLAN configurations across multiple switches in a network.
How does SDN address the issue of scalability in large network infrastructures?
- By decoupling the control plane from the data plane, SDN allows centralized control, making it easier to scale and manage large networks.
- By using traditional routing protocols that automatically scale to accommodate network growth.
- By relying on complex distributed algorithms that dynamically adjust network resources.
- By limiting the size of the network to maintain manageable scalability.
SDN addresses scalability by decoupling the control and data planes, enabling centralized control for easier scaling in large networks.
________ is a common method where the functionality of each network component is verified in order, starting from the physical layer.
- Troubleshooting
- Ping Test
- Trace Route
- Layered Testing
Layered testing is a common method where the functionality of each network component is verified in order, starting from the physical layer.
_________ mode in Port Security allows dynamically learned MAC addresses to be retained even if the switch is restarted.
- Dynamic
- Secure
- Static
- Sticky
Sticky mode in Port Security allows dynamically learned MAC addresses to be retained even if the switch is restarted.
________ was a popular choice for digital telecommunication networks before being overshadowed by newer technologies.
- ISDN (Integrated Services Digital Network)
- ATM (Asynchronous Transfer Mode)
- Frame Relay
- X.25
ISDN (Integrated Services Digital Network) was a popular choice for digital telecommunication networks before being overshadowed by newer technologies like broadband and fiber optics.
Which type of network link is necessary to transport multiple VLANs across network devices?
- Access Link
- Ethernet Link
- Point-to-Point Link
- Trunk Link
A trunk link is necessary to transport multiple VLANs across network devices, allowing for the passage of tagged VLAN traffic.
