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.
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.
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.
In troubleshooting, what is the significance of establishing a baseline performance measure?
- It helps to identify the root cause of the issue
- It provides a reference point for normal network behavior
- It speeds up the troubleshooting process
- It is not relevant in troubleshooting
Establishing a baseline performance measure is significant because it provides a reference point for normal network behavior, making it easier to identify deviations and potential issues.
In a QoS-enabled network, what is the purpose of implementing Traffic Shaping?
- Traffic Shaping is used to limit the rate of outgoing traffic to prevent network congestion and maintain a steady flow of data.
- Traffic Shaping increases the priority of critical traffic, ensuring faster delivery.
- Traffic Shaping is primarily used to block unwanted traffic from entering the network.
- In a QoS-enabled network, Traffic Shaping is not a relevant concept.
Traffic Shaping is implemented to control the rate of outgoing traffic, preventing network congestion and maintaining a steady flow of data.
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.
For a software development company looking to implement continuous integration and continuous delivery (CI/CD) pipelines, which cloud computing service would be most effective?
- Amazon EC2
- AWS Lambda
- AWS CodePipeline
- Amazon S3
AWS CodePipeline is a cloud computing service specifically designed for CI/CD pipelines, making it an effective choice for a software development company aiming to implement continuous integration and continuous delivery.
In GRE tunneling, what is a key challenge related to the security of the encapsulated data?
- Lack of Encryption
- Key Management
- Authentication
- Data Compression
A key challenge in GRE tunneling related to the security of the encapsulated data is authentication.
How do reflexive ACLs function differently from standard and extended ACLs?
- Reflexive ACLs are only applicable to IPv6 traffic
- Reflexive ACLs are stateless and filter traffic based on source and destination IP addresses
- Reflexive ACLs are used primarily for routing decisions
- Reflexive ACLs dynamically allow outbound traffic and create temporary entries for inbound traffic
Reflexive ACLs function differently by dynamically allowing outbound traffic and creating temporary entries for inbound traffic, enhancing security by allowing only legitimate responses.
A network engineer is tasked with increasing the bandwidth and redundancy between two core switches. They decide to use EtherChannel. What factors should they consider in this setup?
- DNS configuration, subnet masks, and latency
- IP addressing scheme, routing protocol, and firewall settings
- MAC address table size, spanning-tree configuration, and switch model
- Number of VLANs, load-balancing algorithm, and link speed
In an EtherChannel setup, factors such as the number of VLANs, load-balancing algorithm, and link speed are critical for optimizing bandwidth and redundancy between core switches.
