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.
How does SD-WAN technology enhance WAN performance and reliability?
- By using traditional routing protocols
- By leveraging multiple WAN connections intelligently
- By increasing bandwidth on a single connection
- By prioritizing all traffic equally
SD-WAN enhances WAN performance and reliability by intelligently leveraging multiple WAN connections, optimizing traffic flow, and providing efficient use of resources.
DNS _________ is a technique used to distribute DNS load and increase reliability.
- Round Robin
- Load Balancing
- Failover
- Caching
DNS Load Balancing is a technique used to distribute DNS load and increase reliability. It involves distributing incoming DNS requests across multiple servers.
How does GLBP avoid the need for each host in the network to be configured with multiple gateway IP addresses?
- Virtual MAC Address
- Load Balancing
- Priority Value
- Preemption
GLBP uses load balancing to distribute traffic across multiple routers. Each host in the network only needs to be configured with a single virtual IP address.
In a ______ topology, each node cooperates in the distribution of data in the network.
- Bus
- Hybrid
- Mesh
- Ring
In a Hybrid topology, each node cooperates in the distribution of data in the network, combining features of different topologies.
