PPP includes a protocol for determining the network layer address of the node at the other end of the link. What is this protocol called?
- ARP
- DHCP
- ICMP
- LCP
PPP includes the Link Control Protocol (LCP), which is responsible for establishing, configuring, maintaining, and terminating the connection.
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.
