20+ TYPSA Interview Questions and Answers

Data packets move in a personal network environment through a series of steps involving routing, addressing, and transmission.

• Data packets are created at the source device and are broken down into smaller chunks for transmission.

• Each packet is assigned a destination address, which helps routers determine the best path for delivery.

• Routers along the network route the packets based on the destination address, ensuring they reach the intended recipient.

• Packets may take different...read more

To troubleshoot BGP going down, check BGP neighbor status, analyze BGP routing table, verify BGP configuration, and check for any network connectivity issues.

• Check BGP neighbor status to see if the neighbors are up and if there are any flaps

• Analyze BGP routing table to identify any inconsistencies or missing routes

• Verify BGP configuration for any errors or misconfigurations

• Check for any network connectivity issues such as link failures or routing protocol mismatches

LSA Types are used in OSPF to describe the type of information contained in the LSA.

• Type 1: Router LSA - contains information about the router and its directly connected networks

• Type 2: Network LSA - describes the networks connected to a multi-access network

• Type 3: Summary LSA - contains information about networks outside of the area

• Type 4: ASBR Summary LSA - describes the ASBR router to the rest of the OSPF domain

• Type 5: External LSA - contains information about external net...read more

OSPF LSA types include Router LSA, Network LSA, Summary LSA, and ASBR Summary LSA.

• Router LSA (Type 1) - Generated by all routers and contains information about directly connected links.

• Network LSA (Type 2) - Generated by DR to advertise the network segment.

• Summary LSA (Type 3, 4, 5) - Generated by ABR to advertise routes to other areas.

• ASBR Summary LSA (Type 4) - Generated by ABR to advertise ASBR information to other areas.

BGP attributes are used to determine the best path for routing traffic between autonomous systems.

• BGP attributes include: AS Path, Next Hop, Local Preference, Weight, Multi-Exit Discriminator (MED), Origin, and Community

• AS Path is a list of autonomous systems that the route has passed through

• Next Hop is the IP address of the next router in the path

• Local Preference is used to indicate the preferred path for outbound traffic

• Weight is a Cisco-specific attribute used to indicate ...read more

Respond promptly with concise information

Routers switch configuration and commands involve setting up and managing network devices for efficient data routing.

• Routers use commands like 'show ip route' to display routing table information

• Configuration involves setting up IP addresses, subnet masks, and default gateways

• Commands like 'show interfaces' can display interface status and configuration details

BGP attributes are used to influence the path selection process in BGP routing.

• BGP attributes include AS_PATH, NEXT_HOP, LOCAL_PREF, etc.

• AS_PATH is a list of AS numbers that the route has traversed.

• NEXT_HOP is the IP address to reach the next hop towards the destination.

• LOCAL_PREF is used to influence outbound traffic.

• MED (Multi-Exit Discriminator) is used to influence inbound traffic.

• Weight is a Cisco-specific attribute used for path selection within the same AS.

• Communities ...read more

Linux Boot Process is the sequence of events that occur from power on to the login prompt.

• BIOS/UEFI firmware initializes hardware

• Bootloader loads kernel into memory

• Kernel initializes system processes and mounts filesystems

• Init process starts system services and user login

• Graphical user interface (GUI) or command line interface (CLI) is presented to user

BGP stands for Border Gateway Protocol. It is a routing protocol used to exchange routing information between different networks.

• BGP is used to connect different autonomous systems (AS) on the internet.

• It is a path-vector protocol that selects the best path for data to travel based on various attributes.

• BGP is commonly used by internet service providers (ISPs) to connect their networks to the internet.

• It is also used in large enterprise networks to connect multiple locations....read more

Loc Perf is not a commonly known term in the field of Network Administration.

• There is no widely accepted definition or explanation for Loc Perf in the context of Network Administration.

• It is possible that the term is specific to a particular organization or system.

• Without more information or context, it is difficult to provide a meaningful answer to this question.

150 computers can connect simultaneously through a network switch or router.

• Use a network switch or router to connect all 150 computers simultaneously.

• Ensure that the network infrastructure can handle the bandwidth and traffic of 150 computers.

• Set up the network with proper IP addressing and subnetting to avoid conflicts.

• Consider using VLANs to segregate traffic and improve network performance.

NIC teaming is the process of combining multiple network interface controllers to work as a single virtual NIC.

• NIC teaming provides redundancy and load balancing for network traffic.

• It can be configured in different modes such as switch independent, LACP, and static.

• NIC teaming is commonly used in server environments to improve network performance and availability.

• Example: Combining two 1 Gbps NICs to create a 2 Gbps virtual NIC.

• Example: Configuring NIC teaming in switch inde...read more

BGP is a routing protocol used to exchange routing information between different networks on the internet.

• BGP uses TCP as its transport protocol.

• BGP routers exchange information about the networks they can reach and the paths to those networks.

• BGP routers select the best path based on a set of criteria, including the shortest AS path and the lowest cost.

• BGP is used by internet service providers to connect their networks together.

• BGP is a complex protocol that requires careful...read more

OSPF formation involves states like Down, Init, 2-Way, Exstart, Exchange, Loading, Full.

• Down state: Initial state when OSPF process is not running.

• Init state: OSPF process is starting up.

• 2-Way state: Routers have exchanged hello packets and are now neighbors.

• Exstart state: Master and slave routers are determined.

• Exchange state: Database description packets are exchanged.
