What is the primary purpose of implementing Quality of Service (QoS) in a network?
- Enhancing network security
- Maximizing network speed
- Prioritizing and managing network traffic
- Expanding network coverage
The primary purpose of implementing Quality of Service (QoS) in a network is to prioritize and manage network traffic efficiently.
In VRRP, what is the significance of having a higher priority value on a router?
- Faster Transition
- Lower Priority
- Preemption
- Virtual IP
In VRRP, a router with a higher priority value becomes the master router. Preemption allows a higher priority router to take over as the master if it becomes available.
For a remote office connection that requires both data compression and error detection, which protocol offers these features in its standard framework?
- IPsec
- L2TP
- PPP
- Frame Relay
PPP (Point-to-Point Protocol) supports data compression and error detection as part of its standard framework, making it suitable for a remote office connection with these requirements.
When a network experiences an issue immediately after a configuration change, what troubleshooting principle should the technician follow first?
- Roll back the configuration change
- Implement additional security measures
- Increase network bandwidth
- Reboot the affected devices
In troubleshooting issues after a configuration change, the technician should first consider rolling back the configuration change to the previous state and observe the impact.
In a large data center, network engineers need to rapidly deploy changes across thousands of devices. What network automation strategy should they adopt to manage this effectively?
- Orchestration
- Configuration Management
- Continuous Integration/Continuous Deployment (CI/CD)
- Scripting
CI/CD is a strategy that allows rapid deployment and changes across a large number of devices in a data center.
Which QoS feature is used to manage congestion by controlling the rate at which packets are sent into the network?
- Traffic shaping
- Packet filtering
- Congestion avoidance
- Link aggregation
Traffic shaping is a QoS feature used to manage congestion by controlling the rate at which packets are sent into the network, preventing network congestion.
What is the process called that enables a cloud service customer to increase or decrease resources as needed?
- Cloud Scaling
- Elasticity
- Resource Provisioning
- Cloud Expansion
Elasticity is the process that enables a cloud service customer to increase or decrease resources as needed.
In BGP, what is the purpose of the AS_PATH attribute?
- Identify Neighbors
- Define Preferred Path
- Prevent Routing Loops
- Advertise Local IP Prefixes
The AS_PATH attribute in BGP is used to prevent routing loops by tracking the Autonomous Systems through which the route has passed.
The _______ time is the interval during which STP listens to and learns the network topology before transitioning to the forwarding state.
- Blocking
- Forwarding
- Learning
- Listening
The listening time in STP is the interval during which the protocol listens to and learns the network topology before transitioning to the forwarding state.
The process of adding a VLAN tag to frames on a trunk port is known as ________.
- VLAN Encapsulation
- VLAN Framing
- VLAN Tagging
- VLAN Untagging
The process of adding a VLAN tag to frames on a trunk port is known as VLAN Encapsulation.
