A company is expanding its network and needs to create multiple subnets for different departments without wasting IP addresses. Which subnetting strategy should they use?

  • CIDR (Classless Inter-Domain Routing)
  • Classful Subnetting
  • Supernetting
  • Variable Length Subnet Masking (VLSM)
Variable Length Subnet Masking (VLSM) allows the creation of multiple subnets with different sizes, efficiently using IP addresses for different departments.

How does Dynamic ARP Inspection (DAI) work in conjunction with DHCP Snooping to enhance network security?

  • Enforcing DHCP lease time
  • Filtering broadcast ARP requests
  • Inspecting DHCP transactions
  • Validating ARP packets
Dynamic ARP Inspection (DAI) works by inspecting DHCP transactions, validating ARP packets, and ensuring that only valid ARP responses are forwarded, enhancing network security.

A company is experiencing issues where clients occasionally get incorrect DNS information, leading to web traffic being misdirected. What DNS configuration aspect should be investigated?

  • DNS Forwarders
  • DNS Recursion
  • DNS Root Servers
  • DNSSEC
DNS recursion involves a DNS server querying other servers on behalf of a client, and issues with it can lead to incorrect DNS information for clients.

In SNMP, the _______ command is used to retrieve a specific piece of information from a managed device.

  • GET
  • SET
  • TRAP
  • WALK
In SNMP, the GET command is used to retrieve a specific piece of information from a managed device.

_________ is crucial in large networks to prevent routing loops during the redistribution process.

  • Route Authentication
  • Route Encryption
  • Route Filtering
  • Route Tagging
Route filtering is crucial in large networks to prevent routing loops during the redistribution process. It involves controlling which routes are allowed or denied during the redistribution process.

Which routing method is typically used in larger, more complex networks where frequently changing network information requires dynamic adjustments?

  • Default Routing
  • Dynamic Routing
  • Hybrid Routing
  • Static Routing
Dynamic routing is typically used in larger, more complex networks where frequently changing network information requires dynamic adjustments to routing tables.

WAN accelerators often use _______ to reduce the amount of data sent across a WAN link.

  • Quality of Service (QoS)
  • Traceroute
  • Compression
  • Latency
WAN accelerators often use Compression to reduce the amount of data sent across a WAN link.

Chassis aggregation is often implemented to create a more _______ and efficient network infrastructure.

  • Agile
  • Redundant
  • Robust
  • Scalable
Chassis aggregation is implemented to create a more robust and efficient network infrastructure.

In a cloud environment, what is the main purpose of orchestration tools like Kubernetes and Docker Swarm?

  • Automate deployment and management of containerized applications
  • Monitor network traffic and security
  • Optimize database performance
  • Facilitate server provisioning
Orchestration tools like Kubernetes and Docker Swarm are used to automate the deployment and management of containerized applications in a cloud environment.

__________ is commonly used in IPv4 networks to conserve the limited number of available IPv4 addresses.

  • CIDR (Classless Inter-Domain Routing)
  • NAT (Network Address Translation)
  • Subnetting
  • VLSM (Variable Length Subnet Masking)
Network Address Translation (NAT) is commonly used in IPv4 networks to conserve the limited number of available IPv4 addresses.

How do QoS policies interact with network routing protocols to ensure optimal traffic flow?

  • QoS policies influence routing decisions based on traffic types.
  • Routing protocols override QoS policies.
  • QoS is applied only to static routes.
  • QoS and routing protocols operate independently.
QoS policies interact with network routing protocols by influencing routing decisions based on the types of traffic, ensuring optimal traffic flow for different applications.

A network that uses ________ can extend a corporate network across multiple sites using the internet.

  • MPLS (Multiprotocol Label Switching)
  • VPN (Virtual Private Network)
  • DNS (Domain Name System)
  • DHCP (Dynamic Host Configuration Protocol)
A network that uses VPN (Virtual Private Network) can extend a corporate network across multiple sites using the internet.
