In a switched network, what technique is used to prevent the broadcast storms that can be caused by switching loops?
- Internet Control Message Protocol (ICMP)
- Routing Information Protocol (RIP)
- Spanning Tree Protocol (STP)
- VLAN Trunking Protocol (VTP)
To prevent broadcast storms caused by switching loops in a network, the 'Spanning Tree Protocol (STP)' is employed. STP helps in determining a loop-free path through the switched network and blocks redundant links to prevent loops.
What is the primary goal of information assurance?
- Ensuring data accuracy
- Maximizing data size
- Protecting data
- Storing data securely
The primary goal of information assurance is 'protecting data.' Information assurance focuses on safeguarding the confidentiality, integrity, and availability of data and information assets.
What is a key component of IT governance that ensures risks associated with IT investments are identified and managed?
- Cryptocurrency
- Data Loss Prevention (DLP)
- IT Portfolio Management
- IT Service Management

You're managing a project and notice that one of the critical path activities is delayed. What is the most likely impact on the project?
- Other project activities won't be affected.
- The project budget will be reduced.
- The project's duration will be extended.
- The project's scope will be enhanced.
When a critical path activity is delayed, it can lead to an extension of the project's duration. The critical path represents the longest path in a project, and any delay in these activities directly affects the project's completion time. Other project activities may be delayed as well due to their dependencies on the critical path activities.
What is the primary purpose of a Content Delivery Network (CDN) in cloud networking?
- Analyzing network traffic
- Hosting databases
- Managing email servers
- Speeding up website loading times
A Content Delivery Network (CDN) is designed to enhance website performance by 'speeding up website loading times.' CDNs store cached content closer to end-users, reducing latency and improving overall user experience.
Which web development approach involves designing a website so it looks and works properly on various devices without requiring a separate version for each device?
- Adaptive Design
- Cross-Browser Compatibility
- Mobile Optimization
- Responsive Design
'Responsive Design' is an approach in web development that focuses on designing websites to adapt to various screen sizes and devices. It ensures that a single version of a website can provide an optimal user experience across different platforms.
In supervised learning, what type of data is used to make predictions?
- Testing data
- Training data
- Unlabeled data
- Validation data
In supervised learning, 'Training data' is used to make predictions. The model learns patterns from this labeled dataset to make predictions on new, unseen data.
In wireless networking, which protocol is specifically designed to secure Wi-Fi networks?
- DNS
- TCP/IP
- WEP (Wired Equivalent Privacy)
- WPA (Wi-Fi Protected Access)
'WPA (Wi-Fi Protected Access)' is a protocol specifically designed to secure Wi-Fi networks. It provides encryption and authentication to protect the confidentiality and integrity of wireless data transmissions.
