CMS IT Services Interview Questions, Process, and Tips

A DHCP server assigns IP addresses to devices on a network, while an APIPA address is a self-assigned IP address when DHCP is not available.

• DHCP server automatically assigns IP addresses to devices on a network

• APIPA address is a self-assigned IP address when DHCP server is not available

• APIPA addresses are in the range of 169.254.0.1 to 169.254.255.254

AD DS is a service provided by Microsoft Windows Server that allows administrators to manage and store information about network resources.

• Stores information about users, computers, and other network objects

• Allows for authentication and authorization of users and computers

• Facilitates group policy management

• Enables single sign-on for users across network resources

VLAN stands for Virtual Local Area Network, a method of segmenting a physical network into multiple virtual networks.

• VLANs help improve network performance, security, and manageability by isolating traffic within specific groups.

• Each VLAN operates as if it is its own separate network, even though devices may physically be connected to the same network switch.

• VLANs are commonly used in large organizations to separate de...read more

Routing is the process of selecting the best path for network traffic to reach its destination.

• Routing involves determining the optimal path for data packets to travel from the source to the destination.

• Routers use routing tables to make decisions on how to forward packets based on destination IP addresses.

• Routing protocols like OSPF and BGP are used to exchange routing information between routers.

• Dynamic routing allow...read more

OSPF (Open Shortest Path First) is a routing protocol used to find the best path for data packets in a network.

• OSPF uses a link-state routing algorithm to determine the best path for data packets.

• Routers in an OSPF network exchange link-state advertisements (LSAs) to build a topology map of the network.

• OSPF calculates the shortest path to each network by using Dijkstra's algorithm.

• OSPF supports multiple areas to scale ...read more

Area 0 in OSPF is the backbone area where all other areas connect.

• Area 0 is also known as the backbone area in OSPF.

• All other OSPF areas must connect to Area 0.

• Area 0 is required for OSPF to function properly.

• Area 0 is used to route traffic between different OSPF areas.

DR/BDR in OSPF are selected based on their priority and router ID.

• DR/BDR election occurs on multi-access networks like Ethernet

• Priority value is used to determine the DR/BDR, default is 1-255

• Router with highest priority becomes DR, second highest becomes BDR

• If priorities are equal, router with highest router ID wins

• Priority can be manually configured to influence DR/BDR selection

Wait attributes in BGP are used to influence the route selection process by delaying the installation of a route into the IP routing table.

• Wait attributes are used to delay the installation of a route into the IP routing table until the wait timer expires.

• This can be useful in scenarios where a route should not be immediately installed, allowing time for other routes to be considered first.

• Wait attributes can help prev...read more

OSPF is an interior gateway protocol used within a single autonomous system, while BGP is an exterior gateway protocol used between different autonomous systems.

• OSPF is a link-state routing protocol, while BGP is a path vector routing protocol.

• OSPF uses a shortest path first algorithm to determine the best path, while BGP uses policies and attributes to make routing decisions.

• OSPF is typically used within a single orga...read more

To synchronize routing from OSPF to BGP, redistribute OSPF routes into BGP and adjust metrics accordingly.

• Redistribute OSPF routes into BGP using route redistribution commands

• Adjust metrics to ensure BGP routes are preferred over OSPF routes

• Use route maps to filter and manipulate routes during redistribution
