• Question 791:

  An employee connects to a work computer from home via the built-in Windows remote desktop connection. Which of the following is MOST likely being used to establish the connection?

  A. RDP

  B. RTP

  C. RIP

  D. RAS

  Correct Answer: A

  Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft, which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software.

• Question 792:

  Which of the following protocols works at the LOWEST layer of the OSI model?

  A. L2TP

  B. PPTP

  C. ISAKMP

  D. IPSec

  Correct Answer: A

  Layer Two Tunneling Protocol (L2TP) is an extension of the Point-to-Point Tunneling Protocol (PPTP) used by an Internet service provider (ISP) to enable the operation of a virtual private network (VPN) over the Internet.

• Question 793:

  Which of the following DHCP properties defines the size of the pool of available IP addresses?

  A. Options

  B. Scope

  C. Leases

  D. Reservations

  Correct Answer: B

  A range of IP addresses that are available to be leased to DHCP clients by the DHCP Server service.

• Question 794:

  Companies trying to cut down on constant documentation of IP addresses could use which of the following?

  A. Longer lease times

  B. More reservations

  C. Larger scopes

  D. Dynamic IP addressing

  Correct Answer: D

  In Dynamic IP addressing all the hosts with private ip address will be patted to the same ip so the administrator will not have to keep track of each and every host with private ip mapped to a static public ip address.

• Question 795:

  Network upgrades have been completed and the WINS server was shutdown. It was decided that NetBIOS network traffic will no longer be permitted. Which of the following will accomplish this objective?

  A. Content filtering

  B. Port filtering

  C. MAC filtering

  D. IP filtering

  Correct Answer: B

  TCP/IP port filtering is the practice of selectively enabling or disabling Transmission Control Protocol (TCP) ports and User Datagram Protocol (UDP) ports on computers or network devices. When used in conjunction with other security practices, such as deploying firewall software at your Internet access point, applying port filters to intranet and Internet servers insulates those servers from many TCP/IP-based security attacks, including internal attacks by malicious users.

• Question 796:

  Which of the following is the FASTEST Ethernet technology?

  A. 10GBaseSR

  B. 10BaseT

  C. 100BaseFX

  D. 1000BaseT

  Correct Answer: A

  10GBASE-SR ("short range") is a port type for multi-mode fiber and uses 850 nm lasers. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 49 and its Physical Medium Dependent PMD in Clause 52. It delivers serialized data at a line rate of 10.3125 Gbit/s.

• Question 797:

  Ann, a technician, installs a new WAP and users are able to connect; however, users cannot access the Internet. Which of the following is the MOST likely cause of the problem?

  A. The signal strength has been degraded and latency is increasing hop count.

  B. An incorrect subnet mask has been entered in the WAP configuration.

  C. The signal strength has been degraded and packets are being lost.

  D. Users have specified the wrong encryption type and routes are being rejected.

  Correct Answer: B

  Due to wrong subnet entered user is unable to communicate with anyone so to communicate he needs to be in right subnet.

• Question 798:

  Users have reported issues accessing an Internet website. The network technician wants to verify network layer connectivity. Which of the following tools can provide the verification?

  A. ping

  B. netstat

  C. route

  D. arp

  Correct Answer: A

  Ping is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer.

• Question 799:

  Which of the following network protocols is used to transport email between servers?

  A. IMAP4

  B. POP3

  C. SNMP

  D. SMTP

  Correct Answer: D

  While electronic mail servers and other mail transfer agents use SMTP to send and receive mail messages, user-level client mail applications typically use SMTP only for sending messages to a mail server for relaying

• Question 800:

  Which of the following network protocols is used to resolve FQDNs to IP addresses?

  A. DNS

  B. FTP

  C. DHCP

  D. APIPA

  Correct Answer: A

  An Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4.
