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.
__________ 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.

- 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.
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.
The _______ protocol allows for one virtual router to act as a default gateway, backed up by a second router in case the primary fails.
- HSRP (Hot Standby Router Protocol)
- OSPF (Open Shortest Path First)
- VRRP (Virtual Router Redundancy Protocol)
- BGP (Border Gateway Protocol)
The HSRP (Hot Standby Router Protocol) allows for one virtual router to act as a default gateway, backed up by a second router in case the primary fails.
What feature allows multiple physical switch ports to be bundled together as a single logical link for increased bandwidth and redundancy?
- Link Aggregation
- Port Mirroring
- VLAN Trunking
- Virtual Router Redundancy Protocol (VRRP)
Link Aggregation allows multiple physical switch ports to be bundled together as a single logical link, providing increased bandwidth and redundancy.
