In a scenario where a company needs to transmit multicast traffic over an IP network that does not support it natively, which tunneling technique would be most appropriate?
- L2TP
- MPLS
- GRE
- PPTP
To transmit multicast traffic over an IP network that does not support it natively, GRE (Generic Routing Encapsulation) tunneling is often the most appropriate technique.
In advanced network designs, why is careful planning required when implementing route redistribution?
- Efficient bandwidth utilization
- Minimized administrative overhead
- Prevention of routing loops
- Simplicity in troubleshooting
Careful planning is required during route redistribution to prevent routing loops, ensuring network stability and reliability.
To reduce the complexity of the routing table and improve efficiency, network engineers use _________.
- Convergence
- Fragmentation
- Load Balancing
- Summarization
To reduce the complexity of the routing table and improve efficiency, network engineers use summarization. Summarization involves representing a group of routes with a single, summarized route entry.
How does a 'root cause analysis' aid in network troubleshooting?
- Identifies the underlying cause of a network issue
- Reboots the network devices to resolve problems
- Monitors network traffic in real-time
- Updates network protocols to the latest versions
Root cause analysis helps identify the underlying cause of a network issue, allowing for targeted and effective troubleshooting.
A network administrator notices intermittent network connectivity issues. On investigation, it's found that STP configuration might be the cause. What aspect of STP should the administrator inspect first?
- Port Security
- Root Bridge Election
- Trunking
- VLAN Configuration
In case of intermittent connectivity issues, the network administrator should inspect the Root Bridge Election process in STP as it plays a crucial role in determining the topology.
Which type of DNS record is crucial for email server verification?
- MX Record
- PTR Record
- CNAME Record
- A Record
The MX (Mail Exchange) record is crucial for email server verification as it specifies the mail servers responsible for receiving emails on behalf of the domain.
When implementing GRE tunnels in a network, what is a critical factor to consider regarding network overhead and performance?
- GRE tunnels introduce additional overhead due to encapsulation, impacting network performance.
- GRE tunnels have no impact on network overhead or performance.
- GRE tunnels decrease overhead, leading to improved network performance.
- GRE tunnels only affect download speed, not upload speed.
Implementing GRE tunnels adds overhead to the network due to encapsulation, impacting overall performance.
Which WAN technology is commonly used for connecting different LANs over a long distance, known for its high speed and reliability?
- DSL
- Fiber Optic
- MPLS
- Satellite
MPLS (Multiprotocol Label Switching) is commonly used for connecting different LANs over a long distance due to its high speed and reliability.
A network administrator needs to configure a WAN link that can handle multiple network protocols and provide authentication. Which protocol should they prioritize?
- PPP
- HDLC
- SNMP
- OSPF
PPP (Point-to-Point Protocol) is suitable for handling multiple network protocols and provides authentication capabilities, making it a preferred choice for configuring a WAN link in this scenario.
Placing an ACL on the _________ of a router can prevent unwanted traffic from traversing the network.
- Egress
- External
- Ingress
- Internal
Placing an ACL on the Egress of a router can prevent unwanted traffic from traversing the network.
