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.

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.

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.

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.

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.

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.

During the process of _________, routes from one routing protocol are injected into another routing protocol.

  • Aggregation
  • Propagation
  • Redistribution
  • Segmentation
During the process of redistribution, routes from one routing protocol are injected into another routing protocol. Redistribution is commonly used when multiple routing protocols are used in the same network.

In SDN, the process of centralizing network intelligence and state is known as ________.

  • Virtualization
  • Abstraction
  • Centralization
  • Orchestration
In SDN, the process of centralizing network intelligence and state is known as Centralization.

Which type of ACL is processed first in a Cisco router, standard or extended?

  • Extended
  • It depends on the router model
  • Standard
  • There is no specific order
In a Cisco router, standard ACLs are processed before extended ACLs.

In QoS, ________ is a mechanism that ensures a specific minimum level of bandwidth to a certain traffic class.

  • Policing
  • Shaping
  • Queuing
  • Guarantees
In Quality of Service (QoS), shaping is a mechanism that ensures a specific minimum level of bandwidth to a certain traffic class.

The integration of _________ in SDN allows for automated network management and orchestration.

  • BGP
  • SNMP
  • Docker
  • VLANs
The integration of SNMP (Simple Network Management Protocol) in SDN allows for automated network management and orchestration.

A company is moving from password-based authentication to a more secure method for device access. Which technology should they consider implementing to improve security?

  • VLANs
  • TACACS+
  • NAT
  • ICMP
TACACS+ (Terminal Access Controller Access-Control System Plus) is a technology that provides secure authentication for device access, improving security over password-based authentication.
