A user reports intermittent network connectivity on a desktop PC. The network link light repeatedly turns on and off. Which action should be performed FIRST?
Reinstall the network adapter driver
Check Ethernet speed and duplex settings on the NIC and switch
Replace the network switch
Enable Quality of Service (QoS)
A single user reports slow file transfers, but other users on the same network are unaffected. Which troubleshooting step best helps isolate the problem?
Reboot the DHCP server
Determine what network activity the user is performing
Reconfigure VLAN assignments
Replace the wireless access point
Several wireless clients experience reduced throughput when an older laptop connects to the network. What is the MOST likely cause?
Suppressed SSID broadcast
Low received signal strength indicator (RSSI)
Mismatch of wireless standards
Incorrect VLAN tagging
Users report choppy voice calls where audio cuts in and out, but no calls are dropped. Which network issue BEST explains this behavior?
Latency
Packet loss
Jitter
DNS resolution failure
A workstation shows 'Limited Connectivity' but the Ethernet cable is connected and link lights are active. What is the MOST likely cause?
Incorrect default gateway
No IP lease received from the DHCP server
Outdated NIC driver
Weak wireless signal
A student installs virtualization software on a Windows laptop to run Linux for training purposes. The virtualization software runs on top of the existing operating system. Which type of hypervisor is being used?
Type 1 (bare-metal)
Type 2 (host-based)
Container hypervisor
Server-side hypervisor
Which of the following BEST describes the primary role of a hypervisor?
Provides network routing between virtual machines
Emulates hardware and manages virtual machines
Encrypts virtual disk files
Replaces the host operating system
A technician wants to safely test unknown software without risking the host operating system. Which use of virtualization BEST fits this scenario?
Desktop virtualization
Server-side virtualization
Sandboxing
Cross-platform virtualization
A system fails to start virtual machines even though sufficient RAM and storage are available. Which hardware requirement is MOST likely missing?
Dedicated GPU
CPU virtualization extensions
Secondary network interface
Solid-state storage
Which statement BEST distinguishes container virtualization from traditional virtual machines?
Containers require a Type 1 hypervisor
Containers run separate guest operating systems
Containers share the host operating system kernel
Containers consume more system resources than VMs
A company wants to ensure it only pays for computing resources when they are actively being used and can scale usage up or down quickly. Which cloud characteristic BEST supports this requirement?
High availability
Rapid elasticity
Metered utilization
Resource pooling
A healthcare organization requires exclusive control over its cloud infrastructure due to regulatory compliance and data sensitivity. Which cloud deployment model is MOST appropriate?
Public
Community
Hybrid
Private
An organization hosts sensitive customer data in a private cloud but uses a public cloud for its public-facing website. Which deployment model is being used?
Community
Public
Hybrid
Private
A developer wants a cloud-based environment that provides operating systems, development tools, and infrastructure without managing the underlying hardware. Which cloud service model BEST meets this need?
Software as a Service (SaaS)
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Desktop as a Service (DaaS)
Which feature is an advantage of cloud file storage solutions?
Requires local storage on each device
Manual synchronization of files
Single-user access only
Automatic file synchronization across devices
A user is unable to access the internet, but can reach other devices on the local network. Which configuration is MOST likely incorrect?
IP address
DNS server
Default gateway
Subnet mask
Which network issue is MOST likely to cause frequent disconnections for wireless users in a crowded office environment?
Low bandwidth allocation
Outdated firmware
Channel interference
Incorrect subnet mask
What is a key benefit of using virtual machines for software development and testing?
Allows isolation of different operating systems on a single host
Requires dedicated hardware for each environment
Prevents network connectivity
Limits resource allocation to one application
Which cloud service model provides users with access to applications over the internet without managing the underlying infrastructure or platform?
Network as a Service (NaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS)
Infrastructure as a Service (IaaS)
Which of the following is a primary advantage of using containers over traditional virtual machines?
Containers cannot be used in cloud environments
Containers run separate kernels for each application
Containers provide faster application deployment
Containers require more hardware resources
