In QoS, what does the term 'classification' refer to?
- Identifying and categorizing network traffic
- Adjusting the speed of data transmission
- Managing network congestion
- Allocating IP addresses
In Quality of Service (QoS), 'classification' involves identifying and categorizing network traffic based on specific criteria to prioritize or treat it differently.
The use of _________ in QoS refers to inspecting the contents of data packets to assign them to the appropriate traffic class.
- Policing
- Shaping
- Queuing
- Classification
In QoS, the use of classification refers to inspecting the contents of data packets to assign them to the appropriate traffic class.
In a scenario where a network requires both data and electrical power transmission to devices, which technology is typically used?
- Fiber Optic
- Power over Ethernet (PoE)
- Token Ring
- Twisted Pair
Power over Ethernet (PoE) is the technology used when a network requires both data and electrical power transmission to devices, simplifying cabling and device power requirements.
What is the primary benefit of using MLPPP over traditional PPP in a network environment?
- Increased Bandwidth
- Enhanced Security
- Load Balancing
- Error Correction
MLPPP (Multilink Point-to-Point Protocol) offers load balancing, enabling the aggregation of multiple physical links into a single logical link to enhance network bandwidth.
A network engineer needs to implement a routing protocol that can scale to a large network with diverse topologies and support rapid convergence. Which protocol should they choose?
- BGP
- EIGRP
- OSPF
- RIP
OSPF (Open Shortest Path First) is a link-state routing protocol suitable for large networks with diverse topologies, providing scalability and rapid convergence.
A company needs to restrict access to its internal servers from the internet, allowing only web traffic. What type of ACL should be implemented?
- Extended ACL
- Reflexive ACL
- Standard ACL
- Time-Based ACL
An extended ACL allows filtering based on source and destination IP addresses, as well as specific protocols like web traffic (HTTP).
How does an extended ACL differ from a standard ACL in terms of its capabilities?
- Allows or denies traffic based on the protocol used
- Applies only to routers
- Filters traffic based on source and destination IP address, as well as protocols and ports
- Filters traffic based on source or destination IP address only
An extended ACL differs from a standard ACL by filtering traffic based on source and destination IP address, as well as protocols and ports.
In a scenario where a company needs to transmit multicast traffic over an IP network that does not support it natively, which tunneling technique would be most appropriate?
- L2TP
- MPLS
- GRE
- PPTP
To transmit multicast traffic over an IP network that does not support it natively, GRE (Generic Routing Encapsulation) tunneling is often the most appropriate technique.
In advanced network designs, why is careful planning required when implementing route redistribution?
- Efficient bandwidth utilization
- Minimized administrative overhead
- Prevention of routing loops
- Simplicity in troubleshooting
Careful planning is required during route redistribution to prevent routing loops, ensuring network stability and reliability.
What is a major advantage of using automated configuration management tools like Ansible or Puppet in network device management?
- Efficient Scalability
- Enhanced Security
- Simplified Management
- Improved Performance
Automated configuration management tools, such as Ansible or Puppet, offer a major advantage in network device management by providing simplified management, streamlining configuration tasks across a network.
