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.
In complex network environments, ________ is used to reduce the risk of VLAN hopping attacks.
- VLAN Access Control
- VLAN Pruning
- VLAN Segmentation
- VLAN Trunking
VLAN Access Control is used in complex network environments to reduce the risk of VLAN hopping attacks.

- VLAN Trunking
To prevent unauthorized access, a network administrator can configure Port Security on switch ports.
In an IPv4 network, what is the primary reason for implementing CIDR (Classless Inter-Domain Routing)?
- To improve security by assigning unique IP addresses to each device.
- To overcome the limitations of the traditional class-based IP addressing scheme and efficiently allocate IP addresses.
- To reduce the size of the routing tables and slow down the growth of the global routing table.
- To simplify subnetting and make it easier for administrators to manage IP address assignments.
CIDR is implemented in IPv4 networks to overcome the limitations of the traditional class-based IP addressing scheme and efficiently allocate IP addresses.
Which type of DNS record is used to translate domain names into IP addresses?
- A Record
- CNAME Record
- PTR Record
- MX Record
An A Record (Address Record) is used to translate domain names into IP addresses.
What is a major advantage of using automated configuration management tools like Ansible or Puppet in network device management?
- Faster Deployment
- Increased Security
- Enhanced Scalability
- Improved Troubleshooting
Automated configuration management tools like Ansible or Puppet enable faster deployment of configurations, reducing manual errors and ensuring consistency.
Which NAT configuration allows incoming connections initiated from the outside network to specific internal hosts?
- Dynamic NAT
- NAPT (Network Address Port Translation)
- Port Forwarding
- Static NAT
Static NAT allows incoming connections initiated from the outside network to specific internal hosts by mapping a public IP address to a private IP address.
