GRE tunnels can carry both IPv4 and IPv6 traffic, making them suitable for _______ environments.
- Virtual Private Networks (VPNs)
- Mixed Protocol
- Multiprotocol
- Dual Stack
GRE tunnels can carry both IPv4 and IPv6 traffic, making them suitable for multiprotocol environments.
How does EtherChannel affect the spanning-tree topology in a network?
- It creates a loop-free redundant path
- It eliminates the need for spanning tree
- It improves convergence time
- It introduces network latency
EtherChannel affects the spanning-tree topology by creating a loop-free redundant path, enhancing network redundancy and reliability.
________ is a common issue in BGP networks caused by incorrect route advertisement.
- Route Flap
- Prefix Deaggregation
- Route Divergence
- Route Oscillation
Route Divergence is a common issue in BGP networks caused by incorrect route advertisement.
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.
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.
