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.
