In WAN optimization, what is the main purpose of implementing compression techniques?
- Reduce data transfer time
- Increase data integrity
- Improve network security
- Minimize latency
The main purpose of implementing compression techniques in WAN optimization is to reduce data transfer time by compressing the data before transmission.
When designing a network monitoring system, an administrator decides to use a protocol that supports both polling and unsolicited updates from network devices. Which protocol should they use?
- SNMP
- Syslog
- NetFlow
- ICMP
SNMP (Simple Network Management Protocol) supports both polling (active requests for information) and unsolicited updates (traps) from network devices, making it suitable for a comprehensive network monitoring system.
What is the primary advantage of using EIGRP over RIP in a network?
- Low bandwidth usage
- Rapid convergence
- Simple configuration
- Support for VLSM
EIGRP (Enhanced Interior Gateway Routing Protocol) has the advantage of supporting Variable Length Subnet Masking (VLSM) in comparison to RIP.
How does BGP's route aggregation feature benefit network performance and scalability?
- Reducing the number of routing entries
- Increasing the BGP peer connections
- Utilizing MPLS technology
- Implementing OSPF as the IGP
BGP's route aggregation feature benefits network performance and scalability by reducing the number of routing entries in the routing table.
How does SDN address the issue of scalability in large network infrastructures?
- By decoupling the control plane from the data plane, SDN allows centralized control, making it easier to scale and manage large networks.
- By using traditional routing protocols that automatically scale to accommodate network growth.
- By relying on complex distributed algorithms that dynamically adjust network resources.
- By limiting the size of the network to maintain manageable scalability.
SDN addresses scalability by decoupling the control and data planes, enabling centralized control for easier scaling in large networks.
________ is a common method where the functionality of each network component is verified in order, starting from the physical layer.
- Troubleshooting
- Ping Test
- Trace Route
- Layered Testing
Layered testing is a common method where the functionality of each network component is verified in order, starting from the physical layer.
_________ 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.
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?
