The Border Gateway Protocol is considered to be a hybrid routing protocol. A. True B. False

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

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

TCP uses a four-step process called a four-way handshake to establish a TCP connection A. True B. False

The CTRL + S key combination can be used to stop an actively running command A. True B. False

Which statement regarding the Border Gateway Protocol (BGP) is accurate? a. BGP is limited to a single autonomous system. b. BGP is exclusively a distance-vector protocol. C. BGP utilizes TCP for communicating updates. d. BGP is a more advanced version of OSPF.

Which statement does NOT accurately describe characteristics of the OSPF protocol? a. OSPF maintains a database of other routers' links. b. OSPF has no hop limits on a transmission path. c. OSPF provides low network overhead. d. OSPF requires very little CPU or memory resources.

In IPv6, what field is used to indicate what sequence of packets from one source to one or multiple destinations a packet belongs to? a. traffic class b. group ID c. flow label d. traffic exchange

Which command will produce statistics about each message transmitted by a host, separated according to protocol type? a. ipconfig -s b. netstat -s c. ipstat -a d. netstat -an

What tcpdump command can be used to filter out all traffic except SSH traffic? a. tcpdump port 22 b. tcpdump -p 22 c. tcpdump only ssh d. tcpdump -f +ssh

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? a. EIGRP will increase CPU utilization on core routers. b. Increased traffic will result from the switch to EIGRP. c. EIGRP may not be available on non-Cisco routers. d. Convergence time will be increased with EIGRP.

What statement regarding the differences between the Windows tracert utility and the Linux/UNIX/macOS traceroute utility is accurate? a. Only tracert can send UDP messages for tracing a path. b. By default, the tracert utility uses ICMP echo requests, while traceroute uses UDP datagrams or TCP SYN messages. c. The Windows tracert utility does not place limits on the TTL of repeated trial messages. d. The tracert utility expects an ICMP port unreachable error message as the final reply to a trace.

What routing metric affects a path's potential performance due to delay? a. theoretical bandwidth b. MTU C. latency d. load

Originally codified by ISO, what does the "intermediate system" in IS-IS (Intermediate System to Intermediate System) stand for? a. The autonomous systems used by an organization. b. An entire network consisting of various network devices. C. The administrative boundaries of an organization. d. An IS-IS capable network router.

The IP connectionless protocol relies on what other protocol to guarantee delivery of data? a. UDP b. ICMP c. TCP d. ARP

What is the purpose of the checksum TCP field? a. It specifies special options, such as the maximum segment size a network can handle. b. It allows the receiving node to determine whether the TCP segment became corrupted during transmission. c. It identifies the data segment's position in the stream of data segments being sent. d. It confirms receipt of data via a return message to the sender.

In a TCP segment, what field indicates how many bytes the sender can issue to a receiver before acknowledgment is received? a. urgent pointer b. sliding-window C. URG flag d. PSH flag

In the event of a duplicate MAC address shared by two hosts on a switched network, what statement is accurate? a. The hosts that share the same MAC addresses will be completely unable to communicate with any other devices. b. The hosts will generate new MAC addresses until the conflict is resolved. c. the host will still send and receive traffic, but traffic may not always reach the correct destination. d. the network switch will eventually crash due to being unable to properly forward traffic.
