The technique of _________ can help in optimizing the performance of a network by reducing the number of individual routes advertised.
- BGP
- OSPF
- Route Redistribution
- Route Summarization
The technique of route summarization can help optimize network performance by reducing the number of individual routes advertised, leading to more efficient routing tables.
In a network setup, which device is used to filter and forward packets between LAN segments based on MAC addresses?
- Bridge
- Hub
- Router
- Switch
A bridge is used to filter and forward packets between LAN segments based on MAC addresses in a network setup.
What is the difference between a site-to-site VPN and a remote access VPN?
- Site-to-Site VPNs connect entire networks, while Remote Access VPNs connect individual users to a network.
- Site-to-Site VPNs use SSL/TLS encryption, while Remote Access VPNs use IPSec.
- Site-to-Site VPNs are only suitable for small organizations, while Remote Access VPNs are suitable for large enterprises.
- Site-to-Site VPNs are always faster than Remote Access VPNs.
A site-to-site VPN connects entire networks, allowing multiple users to access the network, while a remote access VPN connects individual users to a network.
In a network, which device operates at the data link layer and is used to divide a network into segments?
- Bridge
- Hub
- Router
- Switch
A bridge operates at the data link layer and is used to divide a network into segments, controlling traffic between them.
What is the primary purpose of using VLANs in a network?
- Enhanced Network Performance
- Improved Physical Security
- Isolation of Broadcast Domains
- Simplified Network Management
VLANs improve network performance and security by isolating broadcast domains, reducing broadcast traffic and enhancing network segmentation.
What is the primary benefit of using virtualization in cloud computing environments?
- Improved Security
- Cost Reduction
- Increased Network Speed
- Enhanced User Interface
The primary benefit of using virtualization in cloud computing is cost reduction as it allows efficient use of resources and reduces the need for physical infrastructure.
Which network automation tool is known for its agentless architecture and use of playbooks?
- Ansible
- Puppet
- Chef
- SaltStack
Ansible is known for its agentless architecture and use of playbooks to define automation tasks in a declarative language.
During a network expansion, an additional switch is added. The network team wants to ensure this switch never becomes the root bridge in the STP topology. What configuration should be applied?
- Changing MAC Address
- Enabling PortFast
- Increasing Switch Priority
- Lowering Switch Priority
To prevent a switch from becoming the root bridge in the STP topology, the network team should lower the switch priority for that particular switch.
When using VLSM, which of the following is a key advantage over traditional subnetting methods?
- Easier implementation
- Efficient use of IP addresses
- Faster network speeds
- Improved security
VLSM allows for the efficient use of IP addresses by allocating variable-sized subnets, optimizing address space usage.
What protocol is primarily used for network management and monitoring devices on IP networks?
- TCP
- UDP
- ICMP
- SNMP
SNMP (Simple Network Management Protocol) is primarily used for network management and monitoring devices on IP networks.
