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.
In SDN, the process of centralizing network intelligence and state is known as ________.
- Virtualization
- Abstraction
- Centralization
- Orchestration
In SDN, the process of centralizing network intelligence and state is known as Centralization.
During the process of _________, routes from one routing protocol are injected into another routing protocol.
- Aggregation
- Propagation
- Redistribution
- Segmentation
During the process of redistribution, routes from one routing protocol are injected into another routing protocol. Redistribution is commonly used when multiple routing protocols are used in the same network.
PPP includes a protocol for determining the network layer address of the node at the other end of the link. What is this protocol called?
- ARP
- DHCP
- ICMP
- LCP
PPP includes the Link Control Protocol (LCP), which is responsible for establishing, configuring, maintaining, and terminating the connection.
What is the primary purpose of implementing Quality of Service (QoS) in a network?
- Enhancing network security
- Maximizing network speed
- Prioritizing and managing network traffic
- Expanding network coverage
The primary purpose of implementing Quality of Service (QoS) in a network is to prioritize and manage network traffic efficiently.
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.
