The integration of _________ in SDN allows for automated network management and orchestration.
- BGP
- SNMP
- Docker
- VLANs
The integration of SNMP (Simple Network Management Protocol) in SDN allows for automated network management and orchestration.
In QoS, ________ is a mechanism that ensures a specific minimum level of bandwidth to a certain traffic class.
- Policing
- Shaping
- Queuing
- Guarantees
In Quality of Service (QoS), shaping is a mechanism that ensures a specific minimum level of bandwidth to a certain traffic class.
Which type of ACL is processed first in a Cisco router, standard or extended?
- Extended
- It depends on the router model
- Standard
- There is no specific order
In a Cisco router, standard ACLs are processed before extended ACLs.
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.
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.
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.
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.
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.
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.
