A network administrator notices that their AS is receiving suboptimal BGP routes. What BGP attribute should they adjust to influence incoming traffic paths?
- Local Preference
- AS Path
- MED (Multi-Exit Discriminator)
- Weight
The Local Preference attribute in BGP is adjusted to influence incoming traffic paths. It is used within the same AS to set preferences for routes.
In a network with multiple switches, how does the Spanning Tree Protocol (STP) determine the root bridge?
- Highest MAC address
- Highest bridge priority
- Lowest MAC address
- Lowest bridge priority
The Spanning Tree Protocol (STP) determines the root bridge based on the lowest bridge priority. If priorities are the same, it uses the lowest MAC address as a tiebreaker.
In a multi-homed network environment, what BGP strategy could be employed to avoid being a transit AS for other networks?
- Weight
- Local Preference
- AS Path Prepending
- Route Reflectors
AS Path Prepending is a BGP strategy in a multi-homed network to avoid being a transit AS for other networks. It adds the AS number multiple times to make the path less favorable.
IPv6 uses _________ to simplify and improve aspects of IP address assignment and network renumbering.
- Dynamic Host Configuration Protocol (DHCPv6)
- Internet Control Message Protocol version 6 (ICMPv6)
- Routing Information Protocol version 6 (RIPng)
- Stateless Address Configuration (SLAAC)
IPv6 uses Stateless Address Configuration (SLAAC) to simplify and improve aspects of IP address assignment and network renumbering.
The _______ record in DNS is used to point a domain to a physical IP address.
- A
- MX
- CNAME
- PTR
The CNAME (Canonical Name) record in DNS is used to point a domain to a physical IP address.
Which OSI layer handles the routing of packets across different networks?
- Data Link Layer
- Network Layer
- Physical Layer
- Transport Layer
The Network Layer of the OSI model is responsible for routing packets across different networks.
What does GRE stand for in the context of network tunneling?
- Generic Routing Encapsulation
- General Resource Encryption
- Graphical Routing Environment
- Global Reachability Extension
GRE stands for Generic Routing Encapsulation in the context of network tunneling.
How does EIGRP handle load balancing over unequal cost paths?
- Achieves load balancing by always selecting the path with the lowest reported distance.
- Employs a round-robin approach for load balancing over unequal cost paths.
- Supports load balancing only on paths with equal costs, and unequal-cost paths are ignored.
- Utilizes equal-cost load balancing by default, and unequal-cost load balancing can be achieved using the "variance" command.
EIGRP can perform equal-cost load balancing by default and allows unequal-cost load balancing through the use of the "variance" command.
What are the limitations of ScrollSpy when dealing with fixed elements like headers or footers?
- Limited accuracy
- No limitations
- Improved performance
- Enhanced responsiveness
ScrollSpy has limited accuracy when handling fixed elements like headers or footers, impacting navigation precision.
Describe how you would use Bootstrap components to create a multi-level dropdown menu in a navigation bar.
- Utilize the dropdown class for the parent element, apply dropdown-toggle to trigger the dropdown, and use dropdown-menu for the nested menu.
- Apply navbar-dropdown class for the parent and use nested-dropdown for child elements.
- Use nav-dropdown class for the parent and apply sub-menu for the nested items.
- Employ dropdown-menu for the parent and use sub-dropdown for the nested elements.
To create a multi-level dropdown menu in Bootstrap, you can use the dropdown class for the parent element, dropdown-toggle to trigger the dropdown, and dropdown-menu for the nested menu. This allows for a clean and organized navigation structure.
