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 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.
_____ 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.
In a scenario where specific types of traffic must be monitored and controlled, a network administrator would implement ________ ACLs.
- Dynamic
- Extended
- Named
- Standard
In scenarios where specific types of traffic must be monitored and controlled, network administrators would implement Extended ACLs, which are more specific and versatile.
