Networking Quiz: Ch.04

UDP provides error checking, but not sequencing.

False

In IPv6, what field is used to indicate what sequence of packets from one source to one or multiple destinations a packet belongs to?

Flow label

What IPv6 field is similar to the TTL field in IPv4 packets?

Hop limit

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 protocols

What utility is the equivalent to the pathping command on a Linux system?

Mtr

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

What field in an IPv4 packet informs routers the level of precedence they should apply when processing an incoming packet?

Differentiated Services (DiffServ)

Which routing protocol started as a Cisco proprietary protocol and combines some of the features of a link-state protocol with that of distance-vector protocols?

EIGRP

You have been tasked with the replacement of OSPF with EIGRP throughout your organization, which consists of a mixture of Cisco routers and routers from other vendors. What statement is accurate?

EIGRP may not be available on non-Cisco routers

What command will list only current connections, including IP addresses and port numbers?

netstat -n

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

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

If the VLAN tag is present in an Ethernet frame, what is the maximum frame size?

1522 bytes

Originally codified by ISO, what does the "intermediate system" in IS-IS (Intermediate System to Intermediate System) stand for?

An IS-IS capable network router

What occurs when a collision happens on a network?

Each node on the network waits a random amount of time and then resends the transmission

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 routing protocol convergence time defined as?

It is the time it takes for the protocol to recognize the best path in the event of a network change

What routing metric affects a path's potential performance due to delay?

Latency

Which statement does NOT accurately describe characteristics of the OSPF protocol?

OSPF requires very little CPU or memory resources

In a TCP segment, what field indicates how many bytes the sender can issue to a receiver before acknowledgment is received?

Sliding-window

You have been tasked with maintaining a network that is jumbo frame enabled. What does this mean?

The MTU for the network can be as high as 9198 bytes

In the event of a duplicate MAC address shared by two hosts on a switched network, what statement is accurate?

The hosts will still send and receive traffic, but traffic may not always reach the correct destination

What happens when a router receives a packet with a TTL of 0?

The router drops the packet and sends an ICMP TTL expired message back to the host

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

True

In general, a Layer 3 or Layer 4 switch is still optimized for fast Layer 2 data handling.

True

Which traceroute command will perform a trace using ICMP echo requests instead of UDP datagrams to the host srv1.mycompany.com?

traceroute -I srv1.mycompany.com
