An IT manager wants to automate repetitive network management tasks to improve efficiency and accuracy. Which approach or tool should they consider integrating?
- Packet Sniffer
- CLI Scripting
- Ping
- Traceroute
CLI (Command Line Interface) scripting allows the automation of repetitive network management tasks, enhancing efficiency and accuracy by scripting command sequences.
In IPSec, what is the role of the IKE (Internet Key Exchange) protocol?
- IKE negotiates and establishes security associations (SAs) between devices.
- IKE encrypts user data for secure transmission.
- IKE authenticates users during the VPN connection setup.
- IKE is responsible for routing decisions in IPSec networks.
In IPSec, the IKE protocol negotiates and establishes security associations (SAs) between devices, ensuring secure communication.
________ is a QoS technique that prioritizes packets based on their sensitivity to delay.
- Traffic Shaping
- Packet Sniffing
- Traffic Policing
- Low Latency Queuing
Low Latency Queuing is a QoS technique that prioritizes packets based on their sensitivity to delay.
How do modern routers differ from traditional routers in terms of functionality and network management?
- Application Layer Gateway (ALG)
- Dynamic Routing Protocols
- Network Address Translation (NAT)
- Packet Filtering
Modern routers employ dynamic routing protocols, enhancing network management and adaptability compared to traditional routers.
The _______ field in the IPv4 header is used to limit the lifespan of a packet.
- Checksum
- Destination Address
- Source Address
- TTL (Time to Live)
The Time to Live (TTL) field in the IPv4 header is used to limit the lifespan of a packet by specifying the maximum number of hops the packet can take.
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.
