NEW QUESTION # 265
A company wants to implement a disaster recovery site for non-critical applications, which can tolerate a short period of downtime. Which of the following types of sites should the company implement to achieve this goal?
- A. warm
- B. Hot
- C. Passive
- D. Cold
Answer: A
Explanation:
Explanation
The type of site that the company should implement for non-critical applications that can tolerate a short period of downtime is a warm site. A warm site is a disaster recovery site that has some pre-installed equipment and software, but not as much as a hot site, which is fully operational and ready to take over the primary site's functions in case of a disaster. A warm site requires some time and effort to activate and synchronize with the primary site, but not as much as a cold site, which has no equipment or software installed and requires a lot of configuration and testing. A passive site is not a common term for a disaster recovery site, but it could refer to a site that only receives backups from the primary site and does not actively participate in the network operations.

NEW QUESTION # 266
A medical building offers patients Wi-Fi in the waiting room. Which of the following security features would be the BEST solution to provide secure connections and keep the medical data protected?
- A. Disabling unneeded switchports
- B. MAC filtering
- C. Isolating the guest network
- D. Securing SNMP
Answer: C
Explanation:
The question asks about the best security feature to provide secure connections and keep the medical data protected for patients who use Wi-Fi in the waiting room of a medical building.
The answer is isolating the guest network, which means creating a separate network for the guests that has no access to the internal network where the medical data is stored. This way, the guests can use the internet without compromising the confidentiality, integrity, and availability of the electronic protected health information (ePHI).
Securing SNMP, MAC filtering, and disabling unneeded switchports are also security features, but they are not the best solution for this scenario. Securing SNMP means encrypting the Simple Network Management Protocol, which is used to monitor and manage network devices. MAC filtering means allowing or denying access to the network based on the MAC address of the device. Disabling unneeded switchports means turning off the ports that are not in use to prevent unauthorized access. These features can help prevent unauthorized access to the network, but they do not isolate the guest network from the internal network, which is the main requirement for this question. Reference:

NEW QUESTION # 267
A network engineer is concerned about VLAN hopping happening on the network. Which of the following should the engineer do to address this concern?
- A. Enable dynamic ARP inspection.
- B. Change the default VLAN.
- C. Configure private VLANS.
- D. Implement ACLs on the VLAN.
Answer: B
Explanation:
Explanation
VLAN hopping is a type of attack that allows an attacker to access or manipulate traffic on a different VLAN than the one they are connected to. One way to prevent VLAN hopping is to change the default VLAN on a switch. The default VLAN is the VLAN that is assigned to all ports on a switch by default, usually VLAN 1. If an attacker connects to an unused port on a switch that has not been configured with a specific VLAN, they can access or spoof traffic on the default VLAN. By changing the default VLAN to an unused or isolated VLAN, the network administrator can prevent unauthorized access or interference with legitimate traffic on other VLANs.

NEW QUESTION # 272
Which of the following will reduce routing table lookups by performing packet forwarding decisions independently of the network layer header?
- A. VRRP
- B. MPLS
- C. EIGRP
- D. mGRE
Answer: B
Explanation:
Multiprotocol Label Switching, or MPLS, is a networking technology that routes traffic using the shortest path based on "labels," rather than network addresses, to handle forwarding over private wide area networks. As a scalable and protocol-independent solution, MPLS assigns labels to each data packet, controlling the path the packet follows. MPLS greatly improves the speed of traffic, so users don't experience downtime when connected to the network.

NEW QUESTION # 276
A network technician needs to install security updates on several switches on me company's network. The management team wants this completed as quickly and efficiently as possible. Which of the following should the technician do to perform the updates?
- A. Connect a USB memory stick to each switch and perform the update.
- B. Replace each old switch with new switches that have the updates already performed.
- C. Configure a TFTP server. SSH into each device, and perform the update.
- D. Upload the security update onto each switch using a terminal emulator and a console cable.
Answer: C
Explanation:
The best option to install security updates on multiple switches is to use a TFTP (Trivial File Transfer Protocol) server and SSH (Secure Shell) connections. A TFTP server is a simple and lightweight file server that can host the update files and transfer them to the switches over the network. SSH is a secure and encrypted protocol that can be used to remotely access and configure the switches. The technician can use SSH to log into each switch, download the update file from the TFTP server, and apply the update. This method is faster and more efficient than using a terminal emulator and a console cable, which would require physical access to each switch and a serial connection. It is also more cost-effective and less disruptive than replacing the switches with new ones. Using a USB memory stick is also possible, but it would still require physical access to each switch and a USB port, which may not be available on all models.

NEW QUESTION # 282
A customer calls the help desk to report that users are unable to access any network resources_ The issue started earlier in the day when an employee rearranged the wiring closet A technician goes to the site but does not observe any obvious damage. The statistics output on the switch indicates high CPI-J usage, and all the lights on the switch are blinking rapidly in unison_ Which of the following is the most likely explanation for these symptoms?
- A. The switch was rebooted and set to run in safe mode.
- B. The line between the switch and the upstream router was removed
- C. A Cat 6 cable from the modem to the router was replaced with Cat 5e.
- D. A cable was looped and created a broadcast storm.
Answer: D
Explanation:
A cable was looped and created a broadcast storm is the most likely explanation for the symptoms of high CPU usage and blinking lights on the switch. A cable loop is a situation where a switch port is connected to another switch port on the same switch or another switch, creating a circular path for network traffic. A cable loop can cause a broadcast storm, which is a network phenomenon where a large number of broadcast or multicast packets are flooded on the network, consuming bandwidth and CPU resources. A broadcast storm can cause network congestion, performance degradation, or failure. A cable loop can occur when an employee rearranges the wiring closet without proper documentation or verification. A cable loop can be prevented or detected by using Spanning Tree Protocol (STP) or loop detection features on the switch. References:

NEW QUESTION # 283
A wireless network technician is receiving reports from some users who are unable to see both of the corporate SSIDs on their mobile devices. A site survey was recently commissioned, and the results verified acceptable RSSI from both APs in all user areas. The APs support modern wireless standards and are all broadcasting their SSIDs. The following table shows some of the current AP settings:
Which of the following changes would result in all of the user devices being capable of seeing both corporate SSIDs?
- A. Implementing omnidirectional antennas for both APs
- B. Implementing the WPA2 Enterprise authentication standard
- C. Configuring both APs to use the 802.11ac wireless standard
- D. Configuring the highest power settings for both APs
Answer: C
Explanation:
The change that would result in all of the user devices being capable of seeing both corporate SSIDs is configuring both APs to use the 802.11ac wireless standard. 802.11ac is a wireless standard that operates in the 5 GHz frequency band and offers high data rates and performance. However, not all wireless devices support 802.11ac, especially older ones that only operate in the 2.4 GHz frequency band. In the table, AP1 uses 802.11b, which is an outdated wireless standard that operates in the 2.4 GHz frequency band and offers low data rates and performance. AP2 uses 802.11a, which is an older wireless standard that operates in the 5 GHz frequency band and offers moderate data rates and performance. Therefore, some user devices may not be able to see both SSIDs because they are incompatible with either 802.11b or 802.11a. By configuring both APs to use 802.11ac, which is backward compatible with previous wireless standards, all user devices should be able to see both SSIDs.

- A. Restricting physical access to the switch
- B. Blocking inbound SSH connections
- C. Removing the gateway from the network configuration
- D. Changing the default password
Answer: D
Explanation:
Explanation
Changing the default password is a hardening technique that best mitigates the use of publicly available information, such as vendor documentation, online forums, or hacking tools, that may reveal the default credentials of a commercial switch. By changing the default password to a strong and unique one, the network technician can prevent unauthorized access to the switch configuration and management.
