PPP includes a protocol for determining the network layer address of the node at the other end of the link. What is this protocol called?
- ARP
- DHCP
- ICMP
- LCP
PPP includes the Link Control Protocol (LCP), which is responsible for establishing, configuring, maintaining, and terminating the connection.
During the process of _________, routes from one routing protocol are injected into another routing protocol.
- Aggregation
- Propagation
- Redistribution
- Segmentation
During the process of redistribution, routes from one routing protocol are injected into another routing protocol. Redistribution is commonly used when multiple routing protocols are used in the same network.
In SDN, the process of centralizing network intelligence and state is known as ________.
- Virtualization
- Abstraction
- Centralization
- Orchestration
In SDN, the process of centralizing network intelligence and state is known as Centralization.
Which type of ACL is processed first in a Cisco router, standard or extended?
- Extended
- It depends on the router model
- Standard
- There is no specific order
In a Cisco router, standard ACLs are processed before extended ACLs.
In QoS, ________ is a mechanism that ensures a specific minimum level of bandwidth to a certain traffic class.
- Policing
- Shaping
- Queuing
- Guarantees
In Quality of Service (QoS), shaping is a mechanism that ensures a specific minimum level of bandwidth to a certain traffic class.
The integration of _________ in SDN allows for automated network management and orchestration.
- BGP
- SNMP
- Docker
- VLANs
The integration of SNMP (Simple Network Management Protocol) in SDN allows for automated network management and orchestration.
A company is moving from password-based authentication to a more secure method for device access. Which technology should they consider implementing to improve security?
- VLANs
- TACACS+
- NAT
- ICMP
TACACS+ (Terminal Access Controller Access-Control System Plus) is a technology that provides secure authentication for device access, improving security over password-based authentication.
The _______ time is the interval during which STP listens to and learns the network topology before transitioning to the forwarding state.
- Blocking
- Forwarding
- Learning
- Listening
The listening time in STP is the interval during which the protocol listens to and learns the network topology before transitioning to the forwarding state.
In SDN, _________ ensures the network's ability to dynamically adjust to changing business needs.
- Network virtualization
- Quality of Service (QoS)
- Traffic Engineering
- SDN Controller
In SDN, Traffic Engineering ensures the network's ability to dynamically adjust to changing business needs.
IPv6's _________ feature allows devices to automatically configure themselves with a globally unique IP address without the need for a server.
- Stateless Address Autoconfiguration (SLAAC)
- Dynamic Host Configuration Protocol version 6 (DHCPv6)
- Neighbor Discovery Protocol (NDP)
- IPv6 over IPv4 tunneling
IPv6's Stateless Address Autoconfiguration (SLAAC) feature allows devices to automatically configure themselves with a globally unique IP address without the need for a server.
What kind of cable is best suited for network environments where electromagnetic interference is a concern?
- Coaxial Cable
- Fiber Optic Cable
- HDMI Cable
- Twisted Pair
Fiber optic cables are best suited for network environments where electromagnetic interference is a concern because they are immune to such interference.
What is the benefit of using a 'top-down' approach in network troubleshooting?
- Speeds up the troubleshooting process by focusing on specific layers
- Prioritizes issues starting from the physical layer up to the application layer
- Resolves issues only at the application layer
- Skips the network layers for faster resolution
A top-down approach in network troubleshooting prioritizes issues starting from the physical layer up to the application layer, ensuring a systematic and efficient resolution process.
