Question 222 · 871 in bank
Select 2Switch 3 was recently added to an existing stack to extend connectivity to various parts of the network. After the update, new employees were not able to print to the main networked copiers from their workstations. Following are the port configurations for the switch stack in question: Switch 1:
Switch 2:
Switch 3:
Which of the following should be configured to resolve the issue? (Choose two.)
Show answer
Answer: AE
Explanation
Correct me if I'm wrong, but I think this should be A & E. A- because the printer ports are shutdown on Switch 3 E- because the printer is on a different VLAN on Switch 3 (should be 60, not 80). There seems to be nothing wrong with the duplexing as full.

A technician receives feedback that some users are experiencing high amounts of jitter while using the wireless network. While troubleshooting the network, the technician uses the ping command with the IP address of the default gateway and verifies large variations in latency. The technician thinks the issue may be interference from other networks and non-802.11 devices. Which of the following tools should the technician use to troubleshoot the issue?
Show answer
Answer: D
Explanation
A spectrum analyzer is a tool that focuses on the physical layer, which will vary based on the type of analyzer. Although vendors make these analyzers for both audio and optical signals, in most cases spectrum analyzers are used to analyze wireless or radio frequency signals. Spectrum analyzers are primarily used to identify and measure the strength of radio signals that are present in the area. They can visually display these signals by frequency on the device. These devices are used to locate sources of interference that may impact the operation of a wireless network.

A technician is installing a cable modem in a SOHO. Which of the following cable types will the technician MOST likely use to connect a modem to the ISP?
Show answer
Answer: A
Explanation
Coaxial cables are commonly used in cable television and broadband cable Internet installations. They are typically used to connect the cable modem to the wall outlet or the cable modem termination system (CMTS) provided by the ISP.

A network administrator is setting up a new phone system and needs to define the location where VoIP phones can download configuration files. Which of the following DHCP services can be used to accomplish this task?
Show answer
Answer: A
Explanation
A DHCP scope option can be used to specify the location of configuration files for VoIP phones, by including the address of the file server as an option in the DHCP scope. The DHCP server can then provide this information to the VoIP phones when they request an IP address, so that they know where to download the configuration files from. This allows the administrator to centrally manage the configuration of the phones, rather than having to manually configure each one.

Question 226 · 871 in bank
An engineer needs to restrict the database servers that are in the same subnet from communicating with each other. The database servers will still need to communicate with the application servers in a different subnet. In some cases, the database servers will be clustered, and the servers will need to communicate with other cluster members. Which of the following technologies will be BEST to use to implement this filtering without creating rules?
Show answer
Answer: A
Explanation
Emmett Dulaney "Use private VLANs: Also known as port isolation, creating a private VLAN is a method of restricting switch ports (now called private ports) so that they can communicate only with a particular uplink. The private VLAN usually has numerous private ports and only one uplink, which is usually connected to a router, or firewall." B & C require creating rules, and D is about controlling the rate of packets to prevent DoS attacks.

A technician was cleaning a storage closet and found a box of transceivers labeled 8Gbps. Which of the following protocols uses those transceivers?
Show answer
Answer: C
Explanation
The transceivers labeled 8Gbps are likely to be used with the Fibre Channel protocol. Fibre Channel is a high-speed networking technology that is primarily used to connect storage devices to servers in storage area networks (SANs). It is capable of transmitting data at speeds of up to 8 Gbps (gigabits per second), and uses specialized transceivers to transmit and receive data over fiber optic cables. Coaxial over Ethernet (CoE) is a networking technology that uses coaxial cables to transmit data, and is not related to the transceivers in question. Internet Small Computer Systems Interface (iSCSI) is a protocol that allows devices to communicate over a network using the SCSI protocol, and does not typically use specialized transceivers. Gigabit interface converter (GBIC) is a type of transceiver used to transmit and receive data over fiber optic cables, but it is not capable of transmitting data at 8 Gbps.

Question 228 · 871 in bank
A customer wants to log in to a vendor's server using a web browser on a laptop. Which of the following would require the LEAST configuration to allow encrypted access to the server?
Show answer
Answer: A
Explanation
A. Secure Sockets Layer (SSL) would require the least configuration to allow encrypted access to the server. SSL is a protocol used for secure communication over the internet and is widely used for web applications. By enabling SSL on the vendor's server, the customer can access it securely using a web browser without requiring additional configurations such as setting up a VPN or remote desktop gateway.

Question 230 · 871 in bank
A network administrator determines that even when optimal wireless coverage is configured, the network users still report constant disconnections. After troubleshooting, the administrator determines that moving from one location to another causes the disconnection. Which of the following settings should provide better network stability?
Show answer
Answer: B
Explanation
In this case, the most likely cause of the constant disconnections when moving from one location to another is likely due to a problem with the roaming functionality of the wireless network. The setting that would likely provide better network stability in this situation is the RSSI roaming threshold, which determines the signal strength required for a client device to remain connected to the wireless network. If the roaming threshold is set too low, the client device may disconnect and reconnect to the network too frequently as it moves between different access points. On the other hand, if the threshold is set too high, the client device may not roam to a new access point when necessary, leading to a loss of connectivity. Adjusting the RSSI roaming threshold to an appropriate value may help to improve the stability of the wireless network in this situation.
