What mechanism does HSRP use to determine the active and standby routers in a network?
- Priority
- Virtual IP
- MAC Address
- Hello Protocol
HSRP uses priority values to determine the active and standby routers in a network. The router with the highest priority becomes the active router.
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.
How does OSPF determine the best route for data packets in its routing table?
- Administrative distance
- Bandwidth
- Cost based on link speed
- Hop count
OSPF (Open Shortest Path First) determines the best route based on the cost, which is calculated using link speed. Lower cost indicates a better route.
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.
________ is a WAN technology that prioritizes data packets based on labels instead of IP addresses.
- MPLS (Multiprotocol Label Switching)
- VPN (Virtual Private Network)
- DNS (Domain Name System)
- DHCP (Dynamic Host Configuration Protocol)
MPLS is a WAN technology that prioritizes data packets based on labels instead of IP addresses.
In which routing method are routing decisions made based on pre-determined, static routes that do not change unless manually updated?
- Default Routing
- Dynamic Routing
- Hybrid Routing
- Static Routing
In static routing, routing decisions are made based on pre-determined, static routes that do not change unless manually updated.
What is the difference between hard and soft QoS policies in terms of enforcement and flexibility?
- Hard QoS: Strict enforcement, less flexibility. Soft QoS: Flexible enforcement, more adaptability.
- Hard QoS: Flexible enforcement, more adaptability. Soft QoS: Strict enforcement, less flexibility.
- Hard QoS: Applied to voice traffic. Soft QoS: Applied to video traffic.
- Hard QoS: Priority for real-time applications. Soft QoS: Priority for non-real-time applications.
The difference between hard and soft QoS policies lies in their enforcement and flexibility. Hard QoS enforces strict rules with less flexibility, while soft QoS offers more adaptability.
What is the best practice for applying ACLs in a network to maximize efficiency and security?
- Apply ACLs as close to the source as possible
- Apply ACLs at the core layer
- Apply ACLs on distribution switches
- Apply ACLs on the perimeter router
The best practice is to apply ACLs as close to the source as possible to minimize unnecessary traffic on the network and maximize security.
