How does switch stacking impact the scalability of a network infrastructure?
- Decreases Scalability
- Depends on the Network Topology
- Increases Scalability
- No Impact on Scalability
Switch stacking increases scalability by allowing multiple physical switches to be managed as a single entity, simplifying network administration and expanding port density.
What is the purpose of using an extended access list in network configuration?
- To filter traffic based on source and destination IP addresses
- To control access to network resources with more granularity
- To provide basic packet filtering
- To prioritize network traffic based on applications
An extended access list allows for more granular control over network traffic, specifying detailed conditions for filtering.
The process of ________ involves assigning different priority levels to various types of network traffic in QoS.
- Shaping
- Marking
- Scheduling
- Queuing
In Quality of Service (QoS), the process of marking involves assigning different priority levels to various types of network traffic.
Which redundancy protocol provides load balancing over multiple routers along with redundancy?
- HSRP
- VRRP
- GLBP
- OSPF
Gateway Load Balancing Protocol (GLBP) provides load balancing over multiple routers along with redundancy.
Which part of an IPv4 address identifies the network portion and the host portion?
- Domain
- Host
- Network
- Subnet
In an IPv4 address, the subnet portion identifies the network, and the host portion identifies the specific device on that network.
In an environment where data security is crucial, ________ cables are preferred for their resistance to eavesdropping and tapping.
- Coaxial
- Fiber optic
- HDMI
- Twisted pair
In environments where data security is crucial, fiber optic cables are preferred for their resistance to eavesdropping and tapping.
What is the primary function of Port Security in a network switch?
- Block all incoming traffic
- Control access to the network based on MAC addresses
- Encrypt data on the network
- Filter traffic based on IP addresses
The primary function of Port Security is to control access to the network based on MAC addresses, allowing only specified devices to connect.
When configuring redistribution on a router, what is a common challenge that network engineers must address?
- Duplicate IP addresses
- Inconsistent metrics
- Route summarization
- Routing loops
A common challenge in redistribution is dealing with inconsistent metrics between different routing protocols, which can impact the selection of optimal routes.
Which layer of the OSI model is responsible for error checking and reliable packet delivery?
- Data Link
- Network
- Physical
- Transport
The Transport Layer in the OSI model is responsible for error checking and reliable packet delivery.
What is the primary function of a network switch in a LAN environment?
- Amplifying signals
- Assigning IP addresses
- Forwarding data between devices
- Routing between networks
The primary function of a network switch in a LAN environment is to forward data between devices within the same network.
