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.
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.
_________ is crucial in large networks to prevent routing loops during the redistribution process.
- Route Authentication
- Route Encryption
- Route Filtering
- Route Tagging
Route filtering is crucial in large networks to prevent routing loops during the redistribution process. It involves controlling which routes are allowed or denied during the redistribution process.
SNMP uses a structure called ______ to manage and organize the information on managed devices.
- MIB
- MAC
- IP
- OID
SNMP uses a structure called MIB (Management Information Base) to manage and organize information on managed devices.
The _________ feature in BGP allows administrators to influence the path selection process.
- Local Preference
- Weight
- AS Path
- MED (Multi-Exit Discriminator)
The Local Preference feature in BGP allows administrators to influence the path selection process.
The process of comparing current network performance with the __________ helps in identifying deviations and potential issues.
- Baseline
- Benchmark
- Snapshot
- Standard
Comparing current network performance with the baseline helps in identifying deviations and potential issues.
