• Question 781:

  A technician has been called about intermittent connectivity near IDF 2. Multiple cables were recently pulled through a common conduit. Which of the following is MOST likely the cause of the problem?

  A. Crosstalk
  B. Bad connectors
  C. Wrong DNS
  D. Duplicate IP address
  A. Crosstalk

• Question 782:

  A user reports that one of their critical programs no longer functions after a recent router upgrade in the office. A network technician is called in to troubleshoot the issue and documentation shows that the software needs full open connections over ports 558, 981, and 382 in order to function. Which of the following tools could the technician BEST use to troubleshoot this issue?

  A. NET USE
  B. IPCONFIG
  C. TRACEROUTE
  D. TELNET

• Question 783:

  Which of the following protocols is the BEST choice for retrieving email on multiple devices?

  A. IMAP4
  B. SMTP
  C. FTP
  D. SNMPv3
  A. IMAP4

• Question 784:

  A technician, Joe, has been tasked with assigning two IP addresses to WAN interfaces on connected routers. In order to conserve address space, which of the following subnet masks should Joe use for this subnet?

  A. /24
  B. /32
  C. /28
  D. /29
  E. /30
  E. /30

  ---

  An IPv4 addressconsists of 32 bits. The first x number of bits in the address is the network address and the remaining bits are used for the host addresses. The subnet mask defines how many bits form the network address and from that, we can calculate how many bits are used for the host addresses. In this question, the /30 subnet mask dictates that the first 30 bits of the IP address are used for network addressing and the remaining 2 bits are used for host addressing. The formula to calculate the number of hosts in a subnet is 2n - 2. The "n" in the host's formula represents the number of bits used for host addressing. If we apply the formula (22 ?2), a /30 subnet mask will provide 2 IP addresses.

• Question 785:

  Which of the following reduces the deployment cost of a wireless LAN?

  A. WPA
  B. 802.1x
  C. MIMO
  D. PoE
  D. PoE

  ---

  Explanation Explanation/Reference:Power over Ethernet or PoE describes any of several standardized or ad-hoc systems which pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points or IP cameras.

  B. Implement a security guard at the facility entrance and a keypad on the datacenter entrance
  C. Implement a CCTV camera and a proximity reader on the datacenter entrance
  D. Implement a biometric reader at the facility entrance and a proximity card at the datacenter entrance
  A. Implement a biometric reader at the datacenter entrance and require passage through a mantrap

• Question 788:

  Which of the following protocols would the network administrator use to protect login credentials when accessing a router terminal session?

  A. SCP
  B. SNMPv3
  C. SSL
  D. SSH

• Question 789:

  A network administrator wishes to configure a trunk between two switches and allow VLANs 5,10,15, and 10 to be passed on the trunk. After configuring and powering on the switches, the network administrator connects them, and the trunk

  becomes active; however, the logs are showing entries containing "native VLAN mismatch."

  

  Based on the table above, which of the following should be done to stop the "native VLAN mismatch" errors? (Select TWO).

  A. Tag VLAN 5 on the trunk on switch 1.
  B. Untag VLAN 5 on the trunk on switch 2.
  C. Tag VLAN 5 on the trunk on switch 2.
  D. Untag VLAN 10 on the trunk on switch 1.
  E. Tag VLAN 10 on the trunk on switch 1.
  F. Tag VLAN 10 on the trunk on switch 2.
  G. Untag VLANs 5,10,15 and 20 on the trunk on switch 1.
  H. Untag VLANs 5,10,15 and 20 on the trunk on switch 2.
  A. Tag VLAN 5 on the trunk on switch 1.
  F. Tag VLAN 10 on the trunk on switch 2.
