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 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.

AAA in network security stands for Authentication, Authorization, and ________.

  • Accounting
  • Access
  • Authentication
  • Authorization
AAA in network security stands for Authentication, Authorization, and Accounting, representing the three core components of network access control.

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.

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.

Which scripting language is commonly used for basic network automation tasks due to its simplicity and readability?

  • Java
  • Python
  • C++
  • Ruby
Python is commonly used for basic network automation tasks due to its simplicity and readability.

_____ routing can lead to suboptimal routing decisions if the network topology changes and the routes are not updated manually.

  • Default
  • Dynamic
  • Hybrid
  • Static
Static routing can lead to suboptimal routing decisions if the network topology changes and the routes are not updated manually.
