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.
What role does packet classification play in Quality of Service (QoS)?
- Identifying and marking packets
- Filtering out unwanted packets
- Encrypting sensitive packets
- Fragmenting large packets
Packet classification in QoS involves identifying and marking packets to facilitate proper prioritization and treatment.
A network designer is selecting cable types for a new corporate office. The requirement is for a reliable, high-speed network that supports data, voice, and video transmission. Which cable type should be prioritized?
- Cat 5e
- Cat 6
- Coaxial
- Fiber Optic
Fiber optic cables are known for their high-speed transmission and reliability, making them suitable for supporting data, voice, and video in a corporate office.
________ technology is vital for monitoring network performance by continuously measuring traffic and bandwidth usage on network links.
- QoS (Quality of Service)
- MPLS (Multiprotocol Label Switching)
- NetFlow
- OSPF (Open Shortest Path First)
NetFlow technology is vital for monitoring network performance by continuously measuring traffic and bandwidth usage on network links.
Which cloud computing deployment model is exclusively operated for a specific organization, either managed internally or by a third-party?
- Public Cloud
- Private Cloud
- Hybrid Cloud
- Community Cloud
A private cloud deployment model is exclusively operated for a specific organization, either managed internally or by a third party.
