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.
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.
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.
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.
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.
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.
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.
