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.

Which scripting language is commonly used for basic network automation tasks due to its simplicity and readability?

  • Java
  • Python
  • C++
  • Ruby
Python is commonly used for basic network automation tasks due to its simplicity and readability.
