In a network that requires both IPv4 and IPv6 support with the capability of load balancing over unequal paths, which routing protocol would be most suitable?

  • BGP
  • EIGRP
  • OSPF
  • RIPng
EIGRP (Enhanced Interior Gateway Routing Protocol) supports both IPv4 and IPv6, along with the capability of load balancing over unequal paths.

Which of the following is a common reason for using NAT in a network?

  • Boosting wireless signal strength
  • Conserving public IP addresses
  • Enhancing data encryption
  • Increasing network complexity
A common reason for using NAT is to conserve public IP addresses by allowing multiple devices in a private network to share a single public IP address.

For a company that needs a routing protocol to efficiently handle frequent network topology changes without causing significant traffic due to routing updates, what would be the best choice?

  • BGP
  • EIGRP
  • OSPF
  • RIP
OSPF (Open Shortest Path First) is a link-state routing protocol designed to efficiently handle frequent network topology changes without causing significant traffic due to routing updates.

A company is expanding its network infrastructure to support IPv6. What should be considered for efficient IPv6 routing and address allocation?

  • Stateless Address Autoconfiguration (SLAAC)
  • Network Address Translation (NAT)
  • Dynamic Host Configuration Protocol (DHCPv6)
  • Subnetting
For efficient IPv6 routing and address allocation, Stateless Address Autoconfiguration (SLAAC) is a key consideration. SLAAC allows devices to configure their IPv6 addresses automatically.

In a newly configured network with several switches, the network engineer needs to ensure a specific switch becomes the root bridge in STP. What configuration change is needed?

  • Changing MAC Address
  • Enabling PortFast
  • Increasing Switch Priority
  • Lowering Switch Priority
To ensure a specific switch becomes the root bridge in STP, the network engineer should increase the switch priority for that particular switch.

In home networking, which cable type is typically used to connect a modem to a router for internet access?

  • Coaxial Cable
  • Fiber Optic Cable
  • HDMI Cable
  • Twisted Pair
Coaxial cables are typically used in home networking to connect a modem to a router for internet access.

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.

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.

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 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.
