Which WAN technology provides dedicated, high-bandwidth connectivity using fiber-optic cable?
- MPLS
- Frame Relay
- DSL
- SONET/SDH
SONET/SDH (Synchronous Optical Networking/Synchronous Digital Hierarchy) provides dedicated, high-bandwidth connectivity using fiber-optic cable.
What feature should be enabled on network devices to secure access and track changes made by different users?
- VLANs
- Port Security
- SNMP
- AAA (Authentication, Authorization, and Accounting)
AAA (Authentication, Authorization, and Accounting) should be enabled on network devices to secure access and track changes made by different users.
How does a VLAN Trunking Protocol (VTP) assist in managing VLANs across multiple switches?
- It allows switches to negotiate VLAN information
- It assigns VLANs dynamically
- It encrypts VLAN information
- It limits the number of VLANs per switch
VTP assists in managing VLANs across multiple switches by allowing switches to negotiate VLAN information automatically.
The ________ header in IPv6 is used to ensure efficient routing and handling of packets.
- Fragment
- Hop-by-Hop Options
- Routing
- Extension
The Hop-by-Hop Options header in IPv6 is used to ensure efficient routing and handling of packets.
A network administrator needs to configure a router to allow multiple devices in the internal network to access the internet using a single public IP address. Which technology should be used?
- Dynamic NAT
- NAT Overload
- PAT
- Static NAT
PAT (Port Address Translation) should be used when a router needs to allow multiple devices in the internal network to access the internet using a single public IP address.
Which NAT configuration allows incoming connections initiated from the outside network to specific internal hosts?
- Dynamic NAT
- NAPT (Network Address Port Translation)
- Port Forwarding
- Static NAT
Static NAT allows incoming connections initiated from the outside network to specific internal hosts by mapping a public IP address to a private IP address.
What is a major advantage of using automated configuration management tools like Ansible or Puppet in network device management?
- Faster Deployment
- Increased Security
- Enhanced Scalability
- Improved Troubleshooting
Automated configuration management tools like Ansible or Puppet enable faster deployment of configurations, reducing manual errors and ensuring consistency.
The process of modifying the characteristics of a traffic flow is known as _________ in QoS.
- Queuing
- Dropping
- Shaping
- Policing
Shaping in QoS refers to the process of modifying the characteristics of a traffic flow.
In what scenario would static routing be more secure compared to dynamic routing?
- Dynamic routing is always more secure than static routing.
- In a scenario where the network topology is stable and predictable, static routing can be more secure than dynamic routing.
- Security is not a consideration in routing protocols.
- Static routing is always more secure than dynamic routing.
In scenarios with a stable and predictable network topology, static routing can be more secure as it reduces the attack surface by not dynamically exchanging routing information.
How does BGP prevent routing loops in inter-domain routing?
- Split Horizon
- Route Poisoning
- Route Aggregation
- AS_PATH
In BGP, the AS_PATH attribute is used to prevent routing loops in inter-domain routing by tracking the path that the route has traversed.
A company is experiencing targeted cyber attacks on its network. Which firewall feature should be implemented for enhanced security?
- Intrusion Prevention System (IPS)
- Stateful Inspection
- Proxy Firewall
- Packet Filtering
An Intrusion Prevention System (IPS) is crucial for detecting and preventing targeted cyber attacks by analyzing network traffic for malicious activity.
In the TCP/IP model, which layer is responsible for end-to-end data transmission and provides error correction?
- Data Link Layer
- Network Layer
- Physical Layer
- Transport Layer
The Transport Layer in the TCP/IP model is responsible for end-to-end data transmission and provides error correction.
