In Bootstrap, the 'boundary' option for Tooltips and Popovers can be set to '___' to restrict the pop-up within a specific element.
- scrollParent
- parentElement
- viewport
- boundaryElement
The 'boundary' option in Bootstrap Tooltips and Popovers can be set to '___' to restrict the pop-up within a specific element. The correct option is viewport, which limits the pop-up within the viewport of the browser.
To customize Bootstrap's primary color, the SASS variable '___' should be modified.
- $primary-color
- $base-color
- $main-color
- $brand-color
In Bootstrap, the variable responsible for the primary color is $primary-color. Modifying this variable allows customization of the primary color throughout the Bootstrap styles.
What are the key considerations when integrating Bootstrap alerts with JavaScript for dynamic interaction?
- Ensuring all alerts have the same color for consistency.
- Using JavaScript to toggle the visibility of alerts.
- Avoiding JavaScript altogether for better performance.
- Applying CSS animations directly to the alert elements.
Integrating Bootstrap alerts with JavaScript involves toggling the visibility of alerts using JavaScript. This approach allows for dynamic user interaction and feedback, enhancing the overall user experience.
In advanced Bootstrap Sass usage, ___ loops can generate CSS based on a set of parameters or variables.
- for
- while
- loop
- repeat
Advanced Bootstrap Sass usage often involves the use of for loops. These loops are powerful tools that can generate CSS based on specified parameters or variables, allowing for dynamic and flexible styles in the Bootstrap framework.
What technique is used in VLSM to avoid IP address exhaustion?
- ARP (Address Resolution Protocol)
- CIDR (Classless Inter-Domain Routing)
- DHCP (Dynamic Host Configuration Protocol)
- NAT (Network Address Translation)
CIDR (Classless Inter-Domain Routing) is the technique used in VLSM to avoid IP address exhaustion by allowing the allocation of address blocks with variable lengths, matching the actual network requirements.
A network engineer is configuring a GRE tunnel to connect two remote sites over the internet. What additional security mechanism should they consider implementing to protect the data?
- IPsec
- SSL
- TLS
- SSH
When configuring a GRE tunnel, additional security can be provided by implementing IPsec to encrypt the data transmitted between the remote sites over the internet.

- Artificial Intelligence
- Machine Learning
- Data Analytics
- DevOps
The integration of Machine Learning in network automation allows for real-time data processing and decision-making based on network state.
When encountering an issue with network performance, what is the initial action a network technician should take?
- Reboot the server
- Update network documentation
- Notify end-users
- Gather information
When facing network performance issues, the initial action a network technician should take is to gather information, including details about the issue and the network environment.
A network engineer is configuring a network that needs a large number of IP addresses. Which IP version should they consider for an ample supply of addresses?
- IPX
- IPv4
- IPv5
- IPv6
IPv6 is designed to provide an ample supply of IP addresses, making it suitable for networks requiring a large number of addresses.
What is the main advantage of using LACP (Link Aggregation Control Protocol) over PAgP (Port Aggregation Protocol) in EtherChannel configuration?
- LACP provides standards-based compatibility
- LACP supports dynamic negotiation with non-Cisco devices
- PAgP is more efficient in high-traffic environments
- PAgP is the only option for Layer 3 EtherChannels
The main advantage of LACP is its standards-based compatibility, allowing dynamic negotiation with devices from different vendors.
