In _______ topology, data is transmitted in one direction only, making it less prone to data collision.
- Bus
- Point-to-Point
- Ring
- Star
In Point-to-Point topology, data is transmitted in one direction only, making it less prone to data collision. This is suitable for dedicated communication between two devices.
In SDN, what term describes the process of making decisions about where traffic is sent in the network?
- Network Virtualization
- OpenFlow
- SDN Controller
- Traffic Engineering
In SDN, the process of making decisions about where traffic is sent in the network is handled by the SDN Controller.
What methodology involves checking each layer of the OSI model in sequence to isolate a network issue?
- Bottom-Up
- Top-Down
- Sideways
- Diagonal
The top-down methodology involves checking each layer of the OSI model in sequence to isolate a network issue, starting from the application layer down to the physical layer.
________ ACLs are more specific and versatile than standard ACLs, as they can filter packets based on port numbers and protocol types.
- Dynamic
- Extended
- Named
- Standard
Extended ACLs are more specific and versatile than standard ACLs, allowing filtering based on port numbers and protocol types.
Which protocol is used to encrypt management sessions with network devices?
- SNMP
- HTTPS
- Telnet
- ICMP
HTTPS (Hypertext Transfer Protocol Secure) is the protocol used to encrypt management sessions with network devices, ensuring secure communication for managing devices.
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.
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.
