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.
