CIS - Networking Fundamentals - 150 - Quiz 4

UDP provides error checking, but not sequencing.

False

Which Network layer protocol reports on the success or failure of data delivery?

ICMP

Routing protocols that enable routers to communicate beyond neighboring routers, allowing each router to independently map the network, are known as which type of protocols?

Link-state Protocol

How is the TTL (Time to Live) field utilized in IPv4?

'TTL', also known as Time to live, is used to control packets from falling into infinite loops or hops.

Which of the following is not a task handled by a router?

A router forwards broadcasts over the network.

What statement regarding the differences between the Windows tracert utility and the Linux/UNIX/macOS traceroute utility is accurate?

By default, the tracert utility uses ICMP echo requests, while traceroute uses UDP datagrams or TCP SYN messages.

At which layer of the OSI model is a packet encapsulated with its own header and trailer to create a frame?

Data Link

ARP tables might contain two different types of entries. What are they, and how are they created?

Dynamic ARP table entries are created when a client makes an ARP request that could not be satisfied by data already in the ARP table. Static ARP table entries are those that someone has entered manually using the ARP utility

Which command will produce statistics about each message transmitted by a host, separated according to protocol type?

netstat -s

What tcpdump command can be used to filter out all traffic except SSH traffic?

tcpdump port 22

The Border Gateway Protocol is considered to be a hybrid routing protocol.

True

The cost of upgrading infrastructure has been a major factor in the slow adoption of IPv6.

True

The pathping utility sends 10 pings per hop by default.

False

When using the Routing Information Protocol (RIP), what is the maximum number of hops a message can take between its source and its destination before the destination is considered unreachable?

15 hops

By default, what is the MTU size on a typical Ethernet network?

1500

Which statement regarding the Border Gateway Protocol (BGP) is accurate?

BGP utilizes TCP for communicating updates.

IPv4 and IPv6 use the same packet format.

False

Routing Information Protocol (RIP) is an interior gateway protocol that uses a link-state algorithm.

False

TCP uses a four-step process called a four-way handshake to establish a TCP connection.

False

What is the purpose of the checksum TCP field?

It allows the receiving node to determine whether the TCP segment became corrupted during transmission.

At which layer of the OSI model is a packet encapsulated with its own header and trailer to create a frame? (#)

Layer 2

The IP connectionless protocol relies on what other protocol to guarantee delivery of data?

TCP

What are some of the basic functions of a network router?

The main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address.

IP is an unreliable, connectionless protocol, as it does not establish a session to send its packets.

True

ARP relies on _____, which transmits simultaneously to all nodes on a particular network segment.

broadcasting
