In a data center, which cable type is best suited for interconnecting networking equipment due to its high bandwidth and low latency characteristics?
- Cat5e
- Cat6a
- Coaxial
- Fiber Optic
Fiber optic cables are best suited for interconnecting networking equipment in data centers due to their high bandwidth and low latency characteristics.
In a live streaming event with high network traffic, what QoS feature should be prioritized to maintain uninterrupted streaming quality?
- Traffic Policing
- Low Latency Queuing (LLQ)
- Weighted Random Early Detection (WRED)
- Traffic Shaping
Low Latency Queuing (LLQ) should be prioritized in a live streaming event to minimize latency and ensure uninterrupted streaming quality even during high network traffic periods.
A company requires a QoS policy to prioritize VoIP traffic over web browsing to ensure clear voice calls. Which QoS technique should be implemented?
- Traffic Shaping
- Priority Queuing
- DiffServ
- RSVP
Priority Queuing is a QoS technique that assigns higher priority to specific types of traffic, making it suitable for prioritizing VoIP over web browsing.
How does Traffic Shaping contribute to WAN optimization?
- Prioritizes network traffic
- Reduces bandwidth usage
- Improves network security
- Increases latency
Traffic Shaping reduces bandwidth usage by controlling the flow of network traffic, contributing to WAN optimization.
How does IPv6 improve routing efficiency compared to IPv4?
- By implementing Classful addressing
- By introducing larger address space and simpler header structure
- By relying on Dynamic Host Configuration Protocol (DHCP)
- By using Network Address Translation (NAT)
IPv6 improves routing efficiency by introducing a larger address space and a simpler header structure compared to IPv4.
In IPv6, which feature is used for automatically configuring addresses and other configuration settings on network devices?
- Dynamic Host Configuration Protocol (DHCP)
- Network Address Translation (NAT)
- Stateless Address Autoconfiguration (SLAAC)
- Subnetting
Stateless Address Autoconfiguration (SLAAC) is used in IPv6 for automatically configuring addresses and other settings on network devices.
What advanced feature of Port Security can be used to restrict the input rate of traffic based on MAC addresses?
- Aging Time
- Sticky MAC addresses
- Traffic Rate Limiting
- Violation Modes
Traffic rate limiting is an advanced feature of Port Security that can be used to restrict the input rate of traffic based on MAC addresses, enhancing network security.
What is the primary purpose of using redundancy protocols like HSRP, VRRP, and GLBP in a network?
- Load balancing
- Network security
- Device redundancy
- Routing protocol
The primary purpose of using redundancy protocols like HSRP, VRRP, and GLBP is to provide device redundancy, ensuring high availability in case of a failure in the network.
In large networks, what is the primary advantage of using a bridge over a hub?
- Efficient Collision Domain Isolation
- Enhanced Security
- Increased Bandwidth
- Reduced Latency
In large networks, a bridge provides efficient collision domain isolation, reducing collisions and enhancing overall network performance.
In PPP, what mechanism is used for error detection and control at the data link layer?
- Cyclic Redundancy Check (CRC)
- Checksum
- Parity Bit
- Hamming Code
PPP uses Cyclic Redundancy Check (CRC) for error detection and control at the data link layer. CRC is a robust method for detecting errors in transmitted data.
