Traffic Shaping reduces bandwidth usage by controlling the flow of network traffic, contributing to WAN optimization.
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.
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.
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.
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 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.
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 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.
