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.
GRE tunnels can be used to transmit multicast traffic over a network that does not natively support it. True or False?
- TRUE
- FALSE
- -
- -
GRE tunnels can be used to transmit multicast traffic over a network that does not natively support it.
The use of _______ technology in cloud environments allows for the efficient management and allocation of computing resources among multiple tenants.
- Virtualization
- Blockchain
- Machine Learning
- Artificial Intelligence
Virtualization technology in cloud environments enables the efficient management and allocation of computing resources among multiple tenants.
What is the primary function of the Application Layer in the OSI model?
- Error checking
- Reliable packet delivery
- Routing
- User interfaces and network services
The primary function of the Application Layer in the OSI model is to provide user interfaces and network services.
