A network administrator needs to ensure secure remote access to network devices for configuration and troubleshooting. What protocol or method would be most appropriate?
- Telnet
- SSH (Secure Shell)
- HTTP
- SNMPv1
Secure Shell (SSH) is the appropriate protocol for secure remote access to network devices for configuration and troubleshooting, providing encrypted communication.
How does MLPPP (Multilink Point-to-Point Protocol) differ fundamentally from standard PPP?
- It supports multiple logical links over a single physical connection.
- It uses a different encapsulation method.
- It is limited to synchronous communication.
- It only works over Ethernet connections.
MLPPP allows for the support of multiple logical links over a single physical connection, providing increased bandwidth and redundancy.
In which routing protocol are areas a fundamental concept for designing a scalable and efficient network?
- BGP
- EIGRP
- OSPF
- RIP
OSPF (Open Shortest Path First) is a link-state routing protocol where areas are a fundamental concept for designing a scalable and efficient network.
An organization is looking to improve network performance by segmenting the network and reducing unnecessary traffic. Which device would be most suitable for this purpose?
- Bridge
- Hub
- Router
- Switch
A switch is ideal for improving network performance by segmenting the network, reducing unnecessary traffic, and providing better bandwidth utilization.
What is the purpose of the Anycast address in IPv6?
- Broadcast communication to all interfaces
- Multicast communication to all interfaces
- Unicast communication to any one of several interfaces
- Unicast communication to the nearest interface
An Anycast address in IPv6 allows communication to any one of several interfaces, typically choosing the nearest one.
Describe the function of a Traffic Policer in a QoS environment.
- A Traffic Policer monitors incoming traffic, enforces traffic policies, and takes actions such as dropping or marking packets based on predefined rules.
- Traffic Policers are responsible for shaping outbound traffic to conform to specified profiles.
- Traffic Policers are used to prioritize outbound traffic based on application requirements.
- A Traffic Policer ensures that only specific types of traffic are allowed in the network, blocking all other traffic.
In a QoS environment, a Traffic Policer monitors incoming traffic, enforces traffic policies, and takes actions such as dropping or marking packets based on predefined rules.
In which topology is every network device connected to two other devices along a circular path, offering redundancy and reliability?
- Bus
- Mesh
- Ring
- Star
In a ring topology, every network device is connected to two other devices in a circular path, providing redundancy and reliability.
