• Question 512:

  A company is using a DHCP server with 12-hour leases for its device configurations. A user records the information that the DHCP server provides and uses the information to connect a device with a manual IP set. Over time, the user experiences intermittent connectivity and recurring connection timeouts. Which of the following is the MOST likely cause of the issue?

  A. A duplicate IP address is on the network.

  B. The user's device is pointing to an incorrect DNS server.

• Question 513:

  A network requirement calls for the network traffic of a specific department within a campus network to be monitored. The network has users from each department located in multiple buildings. Which of the following should be configured to meet this requirement? (Choose two.)

  A. MDIX

  B. 802.1Q

  C. Jumbo frames

  D. Port mirroring

  E. Flow control

  F. LACP

  Correct Answer: BD

  802.1Q is a standard for VLAN tagging, which allows the network administrator to segment the network traffic of different departments into separate VLANs. This makes it easier to monitor and manage the traffic of each department.

  Port mirroring is a feature that allows the network administrator to copy the traffic from one or more ports to another port for analysis. By configuring port mirroring on the ports connected to the specific department, the network administrator can monitor the traffic of that department in real-time.

  A. 802.11a

  B. 802.11ac

  C. 802.11ax

  D. 802.11n

• Question 516:

  A network administrator is assisting a user who is unable to access network services by using hostname on Host 1. Another user in the same office is able to access the network services with no issue on Host 2. The network administrator runs a command on the affected machine and the working machine and compares the following output:

  

  Which of the follow should the network administrator change to restore connectivity?

  A. Change the default gateway on Host 1 to 192.168.1.1.

  B. Change the IPv4 address on Host 2 to 192.168.0.112.

  C. Reconfigure the subnet masks on both hosts.

  D. Update the DNS server on Host 1 to 192.168.0.53.

  Correct Answer: D

• Question 517:

  A network administration team for a medium-sized business has decided to segment the network, logically separating the finance and marketing teams in order to improve performance for both teams. The finance and marketing teams still need to access resources across the subnets, and the router has a single interface. Which of the following should the administrator configure in order to allow the traffic?

  A. Port address translation

  B. Classless masking

  C. IPv6 tunneling

  D. Subinterfaces

  Correct Answer: D

  Subinterfaces: Subinterfaces are virtual interfaces created on a physical router interface, each associated with a specific VLAN or subnet. By configuring subinterfaces, the router can effectively handle traffic from multiple subnets, allowing traffic separation while still enabling communication between the finance and marketing teams.

  Each subinterface is associated with a different VLAN or subnet and can have its own IP address, allowing traffic to be routed between subnets while keeping them logically separated.

• Question 518:

  A retail store recently acquired the store next door. The owners would like this store to support Gigabit Ethernet for up to 328ft (100m). Which of the following is the MOST cost-effective solution?

  A. Cat5

  B. Cat 5e

  C. Cat 6

  D. Cat 7

  Correct Answer: B

• Question 519:

  Which of the following attacks becomes more effective because of global leakages of users' passwords?

  A. Dictionary

  B. Brute-force

  C. Phishing

  D. Deauthentication

  Correct Answer: B

  Brute-force attacks involve trying all possible combinations of passwords until the correct one is found. Global leakages of users' passwords, such as through data breaches, provide attackers with a larger pool of potential passwords to try, making brute-force attacks more effective and potentially quicker in gaining unauthorized access to accounts or systems.

• Question 520:
