PPP includes a protocol for determining the network layer address of the node at the other end of the link. What is this protocol called?
- ARP
- DHCP
- ICMP
- LCP
PPP includes the Link Control Protocol (LCP), which is responsible for establishing, configuring, maintaining, and terminating the connection.
What is the primary purpose of implementing Quality of Service (QoS) in a network?
- Enhancing network security
- Maximizing network speed
- Prioritizing and managing network traffic
- Expanding network coverage
The primary purpose of implementing Quality of Service (QoS) in a network is to prioritize and manage network traffic efficiently.
In VRRP, what is the significance of having a higher priority value on a router?
- Faster Transition
- Lower Priority
- Preemption
- Virtual IP
In VRRP, a router with a higher priority value becomes the master router. Preemption allows a higher priority router to take over as the master if it becomes available.
What is the benefit of using a 'top-down' approach in network troubleshooting?
- Speeds up the troubleshooting process by focusing on specific layers
- Prioritizes issues starting from the physical layer up to the application layer
- Resolves issues only at the application layer
- Skips the network layers for faster resolution
A top-down approach in network troubleshooting prioritizes issues starting from the physical layer up to the application layer, ensuring a systematic and efficient resolution process.
What kind of cable is best suited for network environments where electromagnetic interference is a concern?
- Coaxial Cable
- Fiber Optic Cable
- HDMI Cable
- Twisted Pair
Fiber optic cables are best suited for network environments where electromagnetic interference is a concern because they are immune to such interference.
IPv6's _________ feature allows devices to automatically configure themselves with a globally unique IP address without the need for a server.
- Stateless Address Autoconfiguration (SLAAC)
- Dynamic Host Configuration Protocol version 6 (DHCPv6)
- Neighbor Discovery Protocol (NDP)
- IPv6 over IPv4 tunneling
IPv6's Stateless Address Autoconfiguration (SLAAC) feature allows devices to automatically configure themselves with a globally unique IP address without the need for a server.
In SDN, _________ ensures the network's ability to dynamically adjust to changing business needs.
- Network virtualization
- Quality of Service (QoS)
- Traffic Engineering
- SDN Controller
In SDN, Traffic Engineering ensures the network's ability to dynamically adjust to changing business needs.
_________ topology is known for its simplicity and is commonly used for small local area networks.
- Bus
- Mesh
- Ring
- Star
A Bus topology is known for its simplicity and is commonly used for small local area networks.
What is a potential drawback of improper route summarization in a network?
- Enhanced network security
- Improved scalability
- Increased routing table size
- Reduced network latency
Improper route summarization can lead to an increased routing table size, negatively impacting network performance and scalability.
For a data center requiring high levels of redundancy and interconnectedness between all systems, which topology would provide the optimal structure?
- Bus
- Mesh
- Ring
- Star
In a data center with high redundancy requirements, a mesh topology is optimal as it provides interconnectedness between all systems, minimizing points of failure.
