The _______ time is the interval during which STP listens to and learns the network topology before transitioning to the forwarding state.
- Blocking
- Forwarding
- Learning
- Listening
The listening time in STP is the interval during which the protocol listens to and learns the network topology before transitioning to the forwarding state.
In SDN, _________ ensures the network's ability to dynamically adjust to changing business needs.
- Network virtualization

- SDN Controller
In SDN, Traffic Engineering ensures the network's ability to dynamically adjust to changing business needs.
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.
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.
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 is a significant consideration when configuring ACLs on a network that includes both IPv4 and IPv6 traffic?
- A single ACL can effectively filter both IPv4 and IPv6 traffic
- ACLs are not applicable to IPv6 traffic
- ACLs for IPv4 and IPv6 must be configured separately
- IPv6 traffic is not subject to ACLs
When configuring ACLs for a network with both IPv4 and IPv6 traffic, it's crucial to consider that ACLs for each protocol must be configured separately to ensure proper filtering.
For advanced WAN troubleshooting, which is a key metric to monitor in a network performance management tool?
- Throughput
- Latency
- MTU (Maximum Transmission Unit)
- Round-Trip Time (RTT)
Latency is a key metric to monitor in a network performance management tool for advanced WAN troubleshooting, as it measures the delay in data transmission.
When configuring a VPN, what is an essential consideration for ensuring secure data transmission?
- Using a static IP address for VPN endpoints to simplify configuration.
- Enabling split tunneling to optimize network performance.
- Implementing strong encryption algorithms and key management for data confidentiality.
- Disabling authentication methods to streamline the VPN connection process.
An essential consideration for ensuring secure data transmission in a VPN is implementing strong encryption algorithms and key management to maintain data confidentiality.
A network administrator needs to configure a solution for securely transmitting sensitive data over the internet to a cloud service provider. Which setup should they consider?
- Direct Internet Connection
- Site-to-Site VPN
- Dedicated Leased Line
- Cloud Connect Service
A site-to-site VPN provides a secure connection over the internet, making it an appropriate choice for transmitting sensitive data to a cloud service provider.
How does NetFlow assist in network management?
- Captures and analyzes network traffic
- Configures routing protocols
- Monitors device temperature
- Manages user authentication
NetFlow assists in network management by capturing and analyzing network traffic to provide insights into network utilization and application performance.
Which basic tool is commonly used to verify connectivity between two network devices?
- Multimeter
- Protocol Analyzer
- Cable Tester
- Ping
The basic tool commonly used to verify connectivity between two network devices is the "Ping" tool, which sends a test message to check if a device is reachable.
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.
