_________ mode in Port Security allows dynamically learned MAC addresses to be retained even if the switch is restarted.
- Dynamic
- Secure
- Static
- Sticky
Sticky mode in Port Security allows dynamically learned MAC addresses to be retained even if the switch is restarted.
________ was a popular choice for digital telecommunication networks before being overshadowed by newer technologies.
- ISDN (Integrated Services Digital Network)
- ATM (Asynchronous Transfer Mode)
- Frame Relay
- X.25
ISDN (Integrated Services Digital Network) was a popular choice for digital telecommunication networks before being overshadowed by newer technologies like broadband and fiber optics.
Which type of network link is necessary to transport multiple VLANs across network devices?
- Access Link
- Ethernet Link
- Point-to-Point Link
- Trunk Link
A trunk link is necessary to transport multiple VLANs across network devices, allowing for the passage of tagged VLAN traffic.
In troubleshooting a network that frequently loses connection, what systematic approach should be used to pinpoint the exact cause?
- Check for interference in wireless networks
- Implement QoS for better connectivity
- Conduct a packet capture analysis
- Update network device firmware
To pinpoint the exact cause of frequent connection losses, a systematic approach involves conducting a packet capture analysis to examine network traffic and identify potential issues.
What is the primary benefit of switch stacking in a network environment?
- Better Performance
- Enhanced Redundancy
- Improved Security
- Increased Scalability
The primary benefit of switch stacking is increased scalability, allowing multiple switches to be interconnected and managed as a single logical unit.
The _______ mechanism in STP prevents the formation of loops by temporarily disabling redundant paths.
- Blocking
- Forwarding
- Listening
- Root Guard
The blocking mechanism in STP prevents the formation of loops by temporarily disabling redundant paths.
In BGP, what is the significance of the LOCAL_PREF attribute in route selection?
- It indicates the route's origin
- It represents the autonomous system number
- It specifies the preferred exit point for outbound traffic
- It determines the administrative distance
The LOCAL_PREF attribute in BGP is significant as it specifies the preferred exit point for outbound traffic in route selection.
To enable many users in a local network to access the internet simultaneously, _________ technique is employed.
- NAT (Network Address Translation)
- Proxy Server
- VLAN (Virtual Local Area Network)
- VPN (Virtual Private Network)
Network Address Translation (NAT) is employed to enable many users in a local network to access the internet simultaneously.
A company's security policy requires that all remote communications with the corporate network must be encrypted and authenticated. Which technology would best fit these requirements?
- VPN (Virtual Private Network)
- SSL/TLS (Secure Sockets Layer/Transport Layer Security)
- IPsec (Internet Protocol Security)
- SSH (Secure Shell)
IPsec is commonly used for encrypting and authenticating remote communications, making it suitable for the described security policy.
In advanced network automation, what is the significance of using containerization technologies like Docker?
- Containers isolate network configurations for security
- Docker simplifies the deployment and scaling of network applications
- Containerization reduces the need for network automation
- Docker provides a graphical user interface for network management
Containerization technologies like Docker simplify the deployment and scaling of network applications in advanced network automation, enhancing flexibility and efficiency.
