In BGP, what term is used to describe a group of IP prefixes advertised by a single AS (Autonomous System)?
- Route Aggregation
- Prefix Summarization
- Autonomous System Path
- Link-State Advertising
In BGP, the term used to describe a group of IP prefixes advertised by a single AS is Route Aggregation. This helps in reducing the size of the routing table.

How does DNSSEC enhance the security of the DNS?
- By encrypting DNS queries
- By providing digital signatures for DNS data
- By blocking malicious DNS traffic
- By anonymizing DNS requests
DNS Security Extensions (DNSSEC) enhance DNS security by providing digital signatures for DNS data, ensuring data integrity and authenticity.
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.

- 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.
