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.
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.
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.
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.
Which of the following is a common reason for using NAT in a network?
- Boosting wireless signal strength
- Conserving public IP addresses
- Enhancing data encryption
- Increasing network complexity
A common reason for using NAT is to conserve public IP addresses by allowing multiple devices in a private network to share a single public IP address.
In a network that requires both IPv4 and IPv6 support with the capability of load balancing over unequal paths, which routing protocol would be most suitable?
- BGP
- EIGRP
- OSPF
- RIPng
EIGRP (Enhanced Interior Gateway Routing Protocol) supports both IPv4 and IPv6, along with the capability of load balancing over unequal paths.
A company is expanding its network infrastructure and requires a setup that allows for easy scalability and centralized management. Which technology would best suit their needs?
- MPLS
- OSPF
- SD-WAN
- VLAN
SD-WAN (Software-Defined Wide Area Networking) would best suit the company's needs as it offers easy scalability and centralized management of network infrastructure.
In a network transitioning from a legacy protocol to a more advanced routing protocol, the network engineer must ensure seamless communication between different parts of the network. What strategy should they employ?
- Quality of Service (QoS)
- Route Redistribution
- Route Summarization
- Virtual LANs (VLANs)
Route redistribution is the strategy to employ when transitioning from a legacy protocol to a more advanced routing protocol, ensuring seamless communication between different parts of the network by redistributing routes between routing protocols.
What is a common method used in QoS to manage network congestion and maintain data quality?
- Network encryption
- Traffic filtering
- Congestion avoidance
- Device authentication
Congestion avoidance is a common method used in QoS to manage network congestion and maintain data quality.
How does Infrastructure as Code (IaC) contribute to network automation?
- It provides a graphical user interface for network configuration
- It enables manual configuration of devices
- It allows defining and managing network infrastructure through code
- It automates network monitoring tasks
Infrastructure as Code (IaC) allows the definition and management of network infrastructure through code, contributing to automation by eliminating manual configuration and ensuring consistency.
In a scenario where specific types of traffic must be monitored and controlled, a network administrator would implement ________ ACLs.
- Dynamic
- Extended
- Named
- Standard
In scenarios where specific types of traffic must be monitored and controlled, network administrators would implement Extended ACLs, which are more specific and versatile.
_____ routing can lead to suboptimal routing decisions if the network topology changes and the routes are not updated manually.
- Default
- Dynamic
- Hybrid
- Static
Static routing can lead to suboptimal routing decisions if the network topology changes and the routes are not updated manually.
