What are the 4 main functions of a dynamic routing protocol?

Explore network topologies, both known and unknown.
Exchange information with other dynamic routers about network status and topology.
Update routing tables based on exchanged information.
Select the optimal way to access destination networks.

What are two purposes of dynamic routing protocols choose two?

What are two functions of dynamic routing protocols? (Choose two.) Dynamic routing protocols exist to discover the network, maintain routing tables, and calculate the best path.

What are the 2 routing protocols?

Many dynamic routing protocols are being used, but most organizations rely on two for their internal routing of IP traffic: OSPF and Cisco Systems’ proprietary Enhanced Interior Gateway Routing Protocol (EIGRP). EIGRP is popular in all-Cisco networks because it’s easier to configure than OSPF.

What are two advantages of static routing over dynamic routing?

Static routing requires very little knowledge of the network for correct implementation. Static routing uses fewer router resources than dynamic routing. Static routing is relatively easy to configure for large networks. Static routing is more secure because it does not advertise over the network.

What are two characteristics of Cisco Express Forwarding CEF )?

CEF consists of two key components: The Forwarding Information Base (FIB) and adjacencies. The FIB is similar to the routing table generated by multiple routing protocols, maintaining only the next-hop address for a particular IP-route.

Which three features are of OSPF routing protocol?

OSPF bases link cost on bandwidth to determine the best route.
OSPF is a distance vector type of protocol.
OSPF uses DUAL algorithm for route computation.
OSPF updates are event triggered.
Speeds up convergence.
Periodic broadcasts to propagate the routes.

What are two reasons why an administrator might choose to use static routing rather than dynamic routing?

Static routing is easier to maintain in large networks.
Static routing is more secure.
Static routing is more scalable.
Static routing uses less router processing and bandwidth.

What is the feature of the OSPF routing protocol?

Open shortest path first (OSPF) is a link-state routing protocol that is used to find the best path between the source and the destination router using its own shortest path first (SPF) algorithm.

What are the functions of routing protocols?

A routed protocol is used to deliver application traffic. It provides appropriate addressing information in its internet layer or network layer to allow a packet to be forwarded from one network to another. Examples of routed protocols are the Internet Protocol (IP) and Internetwork Packet Exchange (IPX).

What are the features of dynamic routing?

Dynamic routing uses multiple algorithms and protocols. The most popular are Routing Information Protocol (RIP) and Open Shortest Path First (OSPF). Dynamic routing protocols allow routers to share information about the network with other routers to allow them to select the best path to reach a destination.

What is dynamic routing used for?

Dynamic routing is a method used to optimize how networks route data. This technique uses different software applications to control protocols and algorithms that connect computers in a dynamic network. Dynamic routers search their database of pathways to choose the best option for each route destination.

Which two protocols are Service Discovery protocols choose two?

The W3C published a working draft specification for service discovery that mentions two existing standards, DNS-based service discovery (DNS-SD) and Simple Service Discovery Protocol (SSDP).

How do you choose a routing protocol?

Metric (it may be hop count or bandwidth)
Amount of Traffic.
Network Size.
VLSM support.
Redundancy.

What is static and dynamic routing protocol?

In static routing routes, the path is updated by the user or an administrator, while in dynamic routing, routes are updated automatically. Static Routing does not use any routing protocols and algorithms, while dynamic routing uses routing protocols and complex algorithms to calculate routing operations.

Which two functions are primary functions of routers choose two?

packet forwarding.
microsegmentation.
domain name resolution.
path selection.
flow control. Answers Explanation & Hints: A router accepts a packet and accesses its routing table to determine the appropriate exit interface based on the destination address.

What is CEF in Cisco router?

Cisco Express Forwarding (CEF) is a packet-switching technique used within Cisco routers. The main purpose of CEF is to optimize the forwarding of packets and increase the packet switching speed.

How does a router determine which destination to use in a routing table quizlet?

Routers use the routing table to determine where to forward packets. the destination ip address in the packet determines the packet destination. they compare this address with their routing table. the result is a decision about which outgoing interface to use to send the packet out of the router.

What are the advantages and disadvantages of dynamic routing?

AdvantagesDisadvantagesAutomatically adapts topology to reroute traffic if possible.Route depends on the current topology.Requires additional resources such as CPU, memory, and link bandwidth.

What are two advantages of static?

Predictability. The path that static routing takes to the destination is very predictable. …
Network Overheads. Unlike dynamic routing, static routing does not contain any overheads ; almost zero. …
Configurations. …
Resource Requirement. …
Bandwidth.

When would it be more beneficial to use a dynamic routing protocol?

When would it be more beneficial to use a dynamic routing protocol instead of static routing? Answers Explanation & Hints: Dynamic routing protocols consume more router resources, are suitable for larger networks, and are more useful on networks that are growing and changing.

Which of the following are true regarding the static routing protocols?

The following statements are true regarding static route assignments: – A single static route cannot respond to network outages. – Static routes are removed from the routing table if the interface goes down. – Static routes are manually configured on the router.

Which two conditions must exist in order to summarize IPv6 routes into a single static IPv6 route?

Which two conditions must exist in order to summarize IPv6 routes into a single static IPv6 route? (Choose two.) The destination networks are contiguous and can be summarized into a single network address. The multiple static routes all use the same exit-interface or next-hop IPv6 address.

Why would a summarized static route be configured on a router group of answer choices?

Why would a summarized static route be configured on a router? A summary route represents multiple networks. A summarized static route does not necessarily provide a better route than a routing protocol does. A default static route would provide a default gateway for a router that is connected to an ISP.

What are two characteristics of OSPF?

Areas contain a group of contiguous hosts and networks.
Routers have a per-area topological database and run the same SPF algorithm.
Each area must be connected to the backbone area known as area 0.
Virtual links can be used to connect to area 0 in emergencies.

Which two variables must match between two OSPF routers to form a neighbor adjacency choose two?

Answers Explanation & Hints: Several variables must match for an OSPF neighbor adjacency to be formed between two OSPF routers. These variables include: area ID, hello and dead timers, interface MTU, and interface subnet.

What is the order of preference for choosing the router ID of an OSPF router?

This router-id must be unique for each OSPF device; without the configuration of the router-id, it will be selected based on the following order: highest loopback interface, highest active (up/up) physical interface.

Which two routing protocols provide the fastest convergence?

EIGRP has the fastest router convergence among the three protocols we are testing.

What are the features of OSPF explain them briefly?

OSPF is a link-state protocol in which all routers in the routing domain exchange information and thus know about the complete topology of the network. Because each router knows the complete topology of the network, the use of the SPF algorithm creates an extremely fast convergence.

What are two characteristics of link state routing protocols?

Link state protocols use characteristics of the route such as speed and cost as well as current congestion to determine the best path, which is typically computed by the Dijkstra algorithm. Link state routers are updated from all the routers in the entire network by passing information from router to nearest router.
