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.

- Caching
- Encryption
- QoS
- Tunneling
To improve data transfer efficiency in WAN, caching is a method that involves storing copies of frequently accessed data.
For outdoor installations where cables are exposed to environmental elements, what type of cable is generally preferred?
- Coaxial Cable
- Direct Burial Cable
- Plenum Cable
- Twisted Pair Cable
Direct burial cables are generally preferred for outdoor installations where cables are exposed to environmental elements.
Which QoS mechanism is used to prioritize certain types of traffic over others?
- Weighted Fair Queuing (WFQ)
- First-Come, First-Served (FCFS)
- Last-In, First-Out (LIFO)
- Round Robin
Weighted Fair Queuing (WFQ) is a QoS mechanism used to prioritize certain types of traffic over others based on assigned weights.
_________ is a method in QoS that dynamically adjusts the priority of different traffic types based on network conditions.
- Policing
- Shaping
- Queuing
- Classification
In QoS, classification is a method that dynamically adjusts the priority of different traffic types based on network conditions.
