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.
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.
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).
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.
PPP uses a ________ protocol for authentication, providing a method for the remote node to establish its identity.
- PAP
- CHAP
- EAP
- RADIUS
PPP uses a CHAP protocol for authentication, providing a method for the remote node to establish its identity.
A network administrator is faced with a sudden network slowdown. They decide to follow a structured approach to identify the issue, starting with the most basic elements. What should be their first step?
- Check physical layer connections
- Analyze network logs
- Examine routing tables
- Monitor bandwidth usage
In troubleshooting a network slowdown, the first step should be to check physical layer connections, ensuring that cables and connections are intact and functioning properly.
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.
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.
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.
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.
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.
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.
