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 IPSec, ________ ensures that each IP packet can be authenticated and verified for integrity.
- Authentication Header (AH)
- Encapsulating Security Payload (ESP)
- Key Management
- Public Key Infrastructure (PKI)
In IPSec, the Authentication Header (AH) ensures that each IP packet can be authenticated and verified for integrity.
How does MPLS improve data forwarding compared to traditional IP routing?
- MPLS uses labels for forwarding, enabling faster and more efficient packet processing compared to traditional IP routing.
- MPLS relies on broadcast-based forwarding, enhancing scalability in large networks.
- MPLS encrypts all data packets, ensuring higher security than traditional IP routing.
- MPLS eliminates the need for routers, simplifying the network architecture.
MPLS (Multiprotocol Label Switching) improves data forwarding by using labels, which allows for faster and more efficient packet processing compared to traditional IP routing.
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.
________ is a type of cable used for carrying high-definition video, audio, and data on a single cable.
- Coaxial
- HDMI
- Optical
- VGA
HDMI (High-Definition Multimedia Interface) is a type of cable used for carrying high-definition video, audio, and data on a single cable.
