A wireless network that is set up by a malicious actor to mimic a legitimate network and trick users into connecting is known as a(n) _______.
- Encryption Key
- Firewall Rule
- Intrusion Detection
- Rogue Access Point
A 'Rogue Access Point' is a deceptive wireless network set up by a malicious actor to imitate a legitimate network. When users connect to it, the attacker can intercept data and potentially launch attacks. Detecting and avoiding rogue access points is crucial for network security.
A _______ is a formal, approved version of a plan against which project execution is compared to measure and manage variances.
- Baseline
- Gantt Chart
- Project Charter
- Stakeholder Register
In project management, a 'baseline' is a crucial concept. It represents a formal, approved version of a project plan, which serves as a reference point to compare and manage variances during project execution. It includes key project elements such as schedule, scope, and budget. A Gantt Chart is a visual representation of a project schedule, a Project Charter is a document that authorizes the project's existence, and a Stakeholder Register is a record of project stakeholders.
When changes are proposed during a project, they're typically reviewed and either approved or denied by a group known as the _______.
- Change Control Board
- Decision Directorate
- Project Conveners
- Revision Review Team
In project management, the group responsible for reviewing and deciding on proposed changes is known as the 'Change Control Board.' They evaluate the potential impact of changes on the project's scope, schedule, and budget, and determine whether to approve or deny the proposed changes. This process helps maintain project integrity.
What is the time complexity of a binary search on a sorted array?
- O(1)
- O(log n)
- O(n log n)
- O(n)
Binary search has a time complexity of O(log n) on a sorted array. It efficiently narrows down the search space with each comparison, making it a highly efficient algorithm for searching.
An organization is assessing its IT risks and identifies a potential threat from an outdated software component. However, the business impact of this threat is deemed to be very low. What might be a suitable course of action?
- Continuously monitor the threat and assess its potential impact.
- Ignore the threat since it has a low business impact.
- Immediately replace the outdated software to eliminate the threat.
- Isolate the outdated software to minimize the risk.
When dealing with a low-impact threat from outdated software, it's typically suitable to continuously monitor the threat and assess its potential impact. This approach allows for a balanced allocation of resources to manage risks effectively.
Which technique involves an attacker sending multiple requests or inputs to a target system to cause it to crash?
- Cross-Site Scripting
- Denial of Service
- Firewall Bypass
- SQL Injection
'Denial of Service' (DoS) is an attack technique where an attacker overwhelms a target system with a high volume of requests or inputs, causing it to become unavailable or crash.
The process of organizing a database to reduce redundancy and improve data integrity is known as _______.
- Aggregation
- Denormalization
- Normalization
- Optimization
'Normalization' is the process of organizing a database to reduce data redundancy, eliminate anomalies, and improve data integrity. It involves breaking down data into separate tables and defining relationships between them.
Your organization's network is growing rapidly, and you need to ensure that routers can learn about network paths automatically without manual configurations. Which approach would be most suitable?
- BGP (Border Gateway Protocol)
- Dynamic Routing
- RIP (Routing Information Protocol)
- Static Routing
To handle a rapidly growing network while enabling routers to learn network paths automatically, 'Dynamic Routing' is the best approach. Dynamic routing protocols, like OSPF or BGP, allow routers to adapt to network changes without manual intervention.
You've detected an unknown device connected to your wireless home network. What should be the immediate first step to ensure the security of your network?
- Block the Device's MAC Address
- Change Wi-Fi Password
- Restart the Router
- Run Antivirus Software
The immediate first step to secure your home network when an unknown device is detected is to 'block the device's MAC address.' This prevents the unknown device from connecting to your network and ensures the security of your network's perimeter.
In network security, the principle that states users should only have the permissions necessary to perform their job functions is called the principle of _______.
- Authentication
- Encryption
- Firewall
- Least Privilege
The principle of 'Least Privilege' dictates that users and processes should have only the minimum permissions required to perform their specific job functions. This minimizes the risk of unauthorized access and potential security breaches.
