A company is planning to implement SDN to automate network provisioning for its cloud services. What key feature of SDN should they focus on?
- OpenFlow
- Southbound API
- Northbound API
- Control Plane Separation
In SDN, the Northbound API allows communication between the applications and the SDN controller, enabling automation and control over network provisioning for cloud services.
Which feature of AAA allows tracking of user activities on network devices?
- Authentication
- Authorization
- Accounting
- Auditing
Accounting, the third A in AAA, allows tracking and logging of user activities on network devices for security and auditing purposes.
What is the primary purpose of Quality of Service (QoS) in networking?
- Ensure optimal performance
- Provide network security
- Enable device discovery
- Facilitate hardware upgrades
The primary purpose of Quality of Service (QoS) in networking is to ensure optimal performance by managing and prioritizing network traffic.
In an enterprise network, there is a need to configure a default gateway redundancy protocol that is not vendor-specific and can work in a multi-vendor environment. Which protocol would be the best choice?
- HSRP (Hot Standby Router Protocol)
- VRRP (Virtual Router Redundancy Protocol)
- GLBP (Gateway Load Balancing Protocol)
- BGP (Border Gateway Protocol)
VRRP is a standard-based protocol that provides default gateway redundancy and can work in a multi-vendor environment, making it a suitable choice for enterprise networks.

- Application
- Internet
- Network
- Transport
In the TCP/IP model, the Transport layer is equivalent to the OSI's Transport Layer.
In an STP network, the port with the lowest _______ cost is selected as the designated port for forwarding frames.
- Bridge
- Path
- Port
- Root
In an STP network, the port with the lowest cost is selected as the designated port for forwarding frames.
_________ is used in QoS to delay excess traffic to conform to a desired traffic profile.
- Dropping
- Queuing
- Shaping
- Policing
Shaping is used in QoS to delay excess traffic and conform it to a desired traffic profile.
________ is a common issue in GRE tunnels due to the added encapsulation headers.
- Fragmentation
- Latency
- Jitter
- Congestion
Fragmentation is a common issue in GRE tunnels due to the added encapsulation headers.
For a large outdoor event requiring a temporary network setup, which cable type would be suitable for outdoor conditions and quick deployment?
- Cat 5e
- Cat 6
- Fiber Optic
- Outdoor-rated Ethernet Cable
An outdoor-rated Ethernet cable is designed for outdoor conditions, providing durability and quick deployment for temporary network setups at large events.
In a network using both OSPF and EIGRP, what is the purpose of redistribution between these two protocols?
- Interoperability
- Load balancing
- Redundancy
- Security
Redistribution between OSPF and EIGRP is done for interoperability, allowing routes learned in one protocol to be advertised and utilized in the other, facilitating communication between different parts of the network.
