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.
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.
