A company is expanding its network infrastructure and requires a setup that allows for easy scalability and centralized management. Which technology would best suit their needs?
- MPLS
- OSPF
- SD-WAN
- VLAN
SD-WAN (Software-Defined Wide Area Networking) would best suit the company's needs as it offers easy scalability and centralized management of network infrastructure.
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 a network transitioning from a legacy protocol to a more advanced routing protocol, the network engineer must ensure seamless communication between different parts of the network. What strategy should they employ?
- Quality of Service (QoS)
- Route Redistribution
- Route Summarization
- Virtual LANs (VLANs)
Route redistribution is the strategy to employ when transitioning from a legacy protocol to a more advanced routing protocol, ensuring seamless communication between different parts of the network by redistributing routes between routing protocols.
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.
