A _______ is a network device that is used to connect devices on a computer network by using packet switching to receive, process, and forward data to the destination device.
- Hub
- Repeater
- Router
- Switch
A switch is a network device that connects devices on a computer network using packet switching to receive, process, and forward data to the destination device.
How does SSH differ from SSL in terms of its primary usage in network security?
- SSH is used for secure remote access and command execution, while SSL is used for securing data transmitted between applications.
- SSL is used for secure remote access, and SSH is used for securing data transmitted between web servers and clients.
- Both SSH and SSL serve the same primary purpose in network security.
- SSH is specifically designed for securing email communication, while SSL is used for securing file transfers.
SSH is primarily used for secure remote access and command execution, distinguishing it from SSL, which secures data transmitted between applications.
To reduce the complexity of the routing table and improve efficiency, network engineers use _________.
- Convergence
- Fragmentation
- Load Balancing
- Summarization
To reduce the complexity of the routing table and improve efficiency, network engineers use summarization. Summarization involves representing a group of routes with a single, summarized route entry.
How does a 'root cause analysis' aid in network troubleshooting?
- Identifies the underlying cause of a network issue
- Reboots the network devices to resolve problems
- Monitors network traffic in real-time
- Updates network protocols to the latest versions
Root cause analysis helps identify the underlying cause of a network issue, allowing for targeted and effective troubleshooting.
A network administrator notices intermittent network connectivity issues. On investigation, it's found that STP configuration might be the cause. What aspect of STP should the administrator inspect first?
- Port Security
- Root Bridge Election
- Trunking
- VLAN Configuration
In case of intermittent connectivity issues, the network administrator should inspect the Root Bridge Election process in STP as it plays a crucial role in determining the topology.
Which type of DNS record is crucial for email server verification?
- MX Record
- PTR Record
- CNAME Record
- A Record
The MX (Mail Exchange) record is crucial for email server verification as it specifies the mail servers responsible for receiving emails on behalf of the domain.
When implementing GRE tunnels in a network, what is a critical factor to consider regarding network overhead and performance?
- GRE tunnels introduce additional overhead due to encapsulation, impacting network performance.
- GRE tunnels have no impact on network overhead or performance.
- GRE tunnels decrease overhead, leading to improved network performance.
- GRE tunnels only affect download speed, not upload speed.
Implementing GRE tunnels adds overhead to the network due to encapsulation, impacting overall performance.
Which WAN technology is commonly used for connecting different LANs over a long distance, known for its high speed and reliability?
- DSL
- Fiber Optic
- MPLS
- Satellite
MPLS (Multiprotocol Label Switching) is commonly used for connecting different LANs over a long distance due to its high speed and reliability.
