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.
Which routing protocol supports automatic summarization at classful network boundaries?
- BGP (Border Gateway Protocol)
- EIGRP (Enhanced Interior Gateway Routing Protocol)
- OSPF (Open Shortest Path First)
- RIP (Routing Information Protocol)
RIP supports automatic summarization at classful network boundaries, aggregating routes into a summarized form.
In QoS, what is the term used for the mechanism that limits the bandwidth used by certain types of traffic?
- Shaping
- Policing
- Queuing
- Dropping
Bandwidth shaping is the mechanism used in QoS to limit the bandwidth used by certain types of traffic.
________ is a cloud computing service model where hardware, software, servers, storage, and network components are provided to the customer.
- IaaS (Infrastructure as a Service)
- PaaS (Platform as a Service)
- SaaS (Software as a Service)
- XaaS (Everything as a Service)
In IaaS (Infrastructure as a Service), all the essential components of cloud infrastructure are provided to the customer.
__________ involves identifying and resolving issues through a process of elimination, focusing on the most likely causes first.
- Troubleshooting
- Root Cause Analysis
- Network Optimization
- Diagnostic Testing
Root cause analysis involves identifying and resolving issues through a process of elimination, focusing on the most likely causes first.
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.
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.
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.
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.
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.
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.
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.
