An organization wants to automate their network configurations and ensure state consistency across devices. Which automation tool should they implement?

  • Ansible
  • Puppet
  • Chef
  • SaltStack
Ansible is a popular automation tool for network configuration management, providing simplicity and ensuring state consistency across devices.

A network engineer is configuring a high-availability network with Cisco routers. They need a protocol that offers both redundancy and load balancing for multiple routers acting as a gateway. Which protocol is most appropriate?

  • HSRP (Hot Standby Router Protocol)
  • VRRP (Virtual Router Redundancy Protocol)
  • GLBP (Gateway Load Balancing Protocol)
  • OSPF (Open Shortest Path First)
GLBP is a Cisco proprietary protocol that provides both redundancy and load balancing for multiple routers acting as a gateway in a high-availability network.

An organization needs to securely connect its main office to three regional offices using the internet. What is the most appropriate solution to ensure security and connectivity?

  • MPLS (Multiprotocol Label Switching)
  • VLAN (Virtual Local Area Network)
  • SD-WAN (Software-Defined Wide Area Network)
  • OSPF (Open Shortest Path First)
SD-WAN is designed for secure and efficient connectivity over the internet, making it a suitable solution for connecting multiple offices securely.

An organization requires a firewall solution that can manage and monitor both internal and external traffic efficiently. What type of firewall should they consider?

  • Stateful Inspection
  • Proxy Firewall
  • Next-Generation Firewall (NGFW)
  • Packet Filtering
A Next-Generation Firewall (NGFW) is designed to manage and monitor both internal and external traffic efficiently with advanced features beyond traditional firewalls.

A network administrator is designing a system with a focus on redundancy and minimal downtime. What network technology should they prioritize?

  • Dynamic Host Configuration Protocol (DHCP)
  • Network Address Translation (NAT)
  • Simple Network Management Protocol (SNMP)
  • Virtual Router Redundancy Protocol (VRRP)
To prioritize redundancy and minimal downtime, the network administrator should prioritize Virtual Router Redundancy Protocol (VRRP), which provides high availability by allowing for a backup router to take over in case the primary router fails.

Switch stacking allows multiple switches to operate as a single _______ entity.

  • Logical
  • Physical
  • Unified
  • Virtual
Switch stacking enables multiple switches to operate as a single virtual entity.

How does PAT (Port Address Translation) differ from traditional NAT?

  • PAT and traditional NAT are essentially the same
  • PAT assigns a unique port number to each private IP address, allowing multiple devices to share a single public IP address
  • PAT is used for routing within a local network, while traditional NAT is used for external communication
  • PAT only works with IPv6, while traditional NAT works with IPv4
PAT (Port Address Translation) assigns a unique port number to each private IP address, enabling multiple devices to share a single public IP address, whereas traditional NAT typically uses one-to-one mapping.

To enhance fault tolerance, switch stacking often employs _______ as a backup in case the primary connection fails.

  • Dual-link
  • Load balancing
  • Port mirroring
  • Redundancy
To enhance fault tolerance, switch stacking often employs redundancy as a backup in case the primary connection fails.

Network automation tools often interface with devices using which protocol for configuration and management tasks?

  • SNMP
  • FTP
  • SSH
  • HTTP
Network automation tools often interface with devices using the SSH (Secure Shell) protocol for configuration and management tasks.

What is a critical factor to consider when implementing Quality of Service (QoS) in a WAN?

  • Bandwidth
  • Latency
  • Jitter
  • Packet Loss
Bandwidth is a critical factor to consider when implementing QoS in a WAN, as it helps prioritize and manage network traffic based on available bandwidth.
