NEW QUESTION # 67
Which of the following issues are present with RIPv2? (Select TWO).
- A. Scalability
- B. Route poisoning
- C. Maximum transmission unit
- D. Unicast
- E. Adjacent neighbors
- F. Time to converge
Answer: A,F
Explanation:
Explanation
The disadvantages of RIP (Routing Information Protocol) include the following.
---Outdated, insecure, and slow. This is your parents' protocol. It was a thing before the Web was born.
---The more well-known problem of the 15 hop limitation in which data must travel
---Convergence time is terrible for information propagation in a network
---Metrics. It determines the number of hops from source to destination, and gives no regard to other factors when determining the best path for data to travel
---Overhead. A good example would be routing tables. These are broadcast at half-minute intervals to other routers regardless of whether the data has changed or not. It's essentially like those old cartoons where the town guard in the walled city cries out, '10 o' the clock and all is well!'.
RIPv2 introduced more security and reduced broadcast traffic, which is relevant for some available answers here.
NEW QUESTION # 68
A global company has acquired a local company. The companies are geographically separate. The IP address ranges for the two companies are as follows:
* Global company: 10.0.0.0/16
* Local company: 10.0.0.0/24
Which of the following can the network engineer do to quickly connect the two companies?
- A. Assign a NAT range to the local company.
- B. Assign an overlapping IP address range to both companies.
- C. Assign a new IP address range to the local company.
- D. Assign static routing to advertise the local company's network.
Answer: C
Explanation:
Assigning a new IP address range to the local company is the best option to quickly connect the two companies without causing any IP address conflicts or overlaps. This option requires reconfiguring the local company's network devices and updating the routing tables on both sides, but it avoids the need for any NAT or static routing solutions that may introduce additional complexity, cost, or performance issues12 Reference1: Connecting Networks with Overlapping IP Ranges 2: What Is Network Address Translation (NAT)?

A help desk supervisor reviews the following excerpt of a call transcript:
Which of the following was the agent trying to accomplish with this exchange?
- A. The agent was verifying full system functionality
- B. The agent was identifying potential effects.
- C. The agent was questioning the obvious.
- D. The agent was trying to duplicate the problem.
Answer: D
Explanation:
Explanation
The agent was trying to duplicate the problem by asking the user to perform the same steps that led to the issue. This is a common troubleshooting technique that helps the agent to identify the root cause of the problem and verify if it is reproducible or intermittent. By duplicating the problem, the agent can also gather more information about the symptoms and error messages that the user encountered.

NEW QUESTION # 70
A Wi-Fi network was originally configured to be able to handle interference from a microwave oven. The microwave oven was recently removed from the office. Now the network administrator wants to optimize the system to maximize the range of the signal. The main sources of signal degradation are the numerous cubicles and wooden walls between the WAP and the intended destination. Which of the following actions should the administrator take?
- A. Change the frequency.
- B. Change the SSID.
- C. Change from omni to directional.
- D. Implement CDMA.
Answer: A
Explanation:
Explanation
- the microwave was already removed from the office
- the signal is OK now
- Notice that the question mentions "numerous cubicles and wooden walls" - meaning the signal now won't have the interference as before
- KEY POINT: the admin wants to "maximize the range of the signal:"
Manually change the frequency to 2.4 GHz for more reliable speeds and range. While 5 GHz gives you a stronger signal, it doesn't travel through walls or ceilings as well, so it doesn't give you the best range.
"Microwave ovens: Older microwave ovens, which might not have sufficient shielding, can emit relatively high-powered signals in the 2.4GHz band, resulting in significant interference with WLAN devices operating in the 2.4GHz band."
NEW QUESTION # 71
A network engineer installed a new fiber uplink for an office and wants to make sure that the link meets throughput requirements. Which of the following tools should the engineer use to verify that the new link is sufficient?
- A. ping
- B. netstat
- C. iperf
- D. tcpdump
Answer: C
Explanation:
iperf is a tool that can measure the bandwidth and quality of a network link by generating and transferring TCP or UDP data streams. iperf can report the maximum achievable throughput, packet loss, jitter, and other statistics for a given link. iperf can be used to test both the uplink and downlink performance of a network link by running it on two endpoints and specifying the direction and duration of the test. iperf can help the engineer verify that the new fiber uplink meets the throughput requirements for the office network.
tcpdump is a tool that can capture and analyze network traffic by filtering and displaying packets based on various criteria. tcpdump can help the engineer troubleshoot network problems, monitor network activity, and inspect packet contents, but it cannot measure the throughput or quality of a network link.
ping is a tool that can test the reachability and latency of a network host by sending and receiving ICMP echo packets. ping can help the engineer check if the new fiber uplink is connected and responsive, and how long it takes for packets to travel between the endpoints, but it cannot measure the throughput or quality of a network link.
netstat is a tool that can display information about the network connections, routing tables, interfaces, and protocols on a network host. netstat can help the engineer view the status and details of the network connections using the new fiber uplink, but it cannot measure the throughput or quality of a network link.

NEW QUESTION # 72
During an incident, an analyst sends reports regularly to the investigation and leadership teams. Which of the following best describes how Pll should be safeguarded during an incident?
- A. Ensure permissions are limited to the investigation team and encrypt the data.
- B. Implement data encryption and create a standardized procedure for deleting data that is no longer needed.
- C. Implement data encryption and store the data so only the company has access.
- D. Ensure the permissions are open only to the company.
Answer: B
Explanation:
Explanation
PII stands for Personally Identifiable Information, which is any data that can be used to identify, contact, or locate a specific individual, such as name, address, phone number, email, social security number, and so on.
PII should be safeguarded during an incident to protect the privacy and security of the individuals involved, and to comply with the legal and ethical obligations of the organization. One way to safeguard PII during an incident is to implement data encryption, which is a process of transforming data into an unreadable format that can only be accessed by authorized parties who have the decryption key. Data encryption can prevent unauthorized access, modification, or disclosure of PII by malicious actors or third parties. Another way to safeguard PII during an incident is to create a standardized procedure for deleting data that is no longer needed, such as after the incident is resolved or the investigation is completed. Deleting data that is no longer needed can reduce the risk of data breaches, data leaks, or data theft, and can also save storage space and resources. A standardized procedure for deleting data can ensure that the data is erased securely and completely, and that the deletion process is documented and audited.

<INPUT TYPE="IMAGE" SRC="javascript : alert ('test') ; ">
Which of the following should be implemented to prevent this type of attack in the future?
- A. Code obfuscation
- B. Output encoding
- C. Input sanitization
- D. Prepared statements
Answer: C
Explanation:
Explanation
Input sanitization is the process of validating and filtering the user input to prevent malicious code or commands from being executed on the web server or the web browser. Input sanitization can prevent this type of attack, which is called cross-site scripting (XSS), by removing or escaping any special characters or scripts that are not expected or allowed in the input field. Input sanitization can be implemented on the server-side or the client-side, or both, to enhance the security of the web application.

NEW QUESTION # 78
A network administrator is troubleshooting a PC that cannot connect to the LAN. The administrator runs the ipconfig command at the command prompt and gets the following output:
Which of the following is misconfigured?
- A. DHCP server
- B. DNS server
- C. Physical address
- D. Subnet mask
Answer: D
Explanation:
Explanation
The subnet mask is a binary value that defines how many bits of an IP address are used to identify the network and how many bits are used to identify the host. The subnet mask also determines the size and number of subnets in a network. The ipconfig command shows the current IP configuration of a device, including the subnet mask. In this case, the subnet mask is misconfigured because it does not match the network address of the device. The device has an IP address of 192.168.1.55, which belongs to the network 192.168.1.0/24 (with a subnet mask of 255.255.255.0). However, the subnet mask is set to 225.225.225.224, which is an invalid value that does not correspond to any network prefix length. This causes the device to be unable to communicate with other devices on the same network or access the default gateway.

An attacker sends more connection requests than a server can handle, causing the server to crash- Which of the following types of attacks is this an example of?
- A. On-path
- B. ARP poisoning
- C. MAC flooding
- D. Denial-of-service
Answer: D
Explanation:
A denial-of-service (DoS) attack is an example of an attack where an attacker sends more connection requests than a server can handle, causing the server to crash. A DoS attack is a type of cyberattack that aims to disrupt the normal functioning of a network service or resource by overwhelming it with excessive or malformed traffic. A DoS attack can prevent legitimate users from accessing the service or resource, resulting in degraded performance, unavailability, or data loss. A DoS attack can target various network layers, protocols, or components, such as servers, routers, firewalls, or applications.

Which of the following changes should the technician make to BEST fix the issue?
- A. Stop logging SSH events.
- B. Adjust the logging level.
- C. Update the logging host IP
- D. Change lo asynchronous logging.
Answer: B
Explanation:
Explanation
The logging level is set to debugging, which is the most verbose and detailed level of logging. This means that the switch will send a lot of information to the syslog server, which can cause excessive network traffic and storage consumption. To fix the issue, the technician should adjust the logging level to a lower value, such as informational or warning, which will reduce the amount of data logged

WAN 2 appears to have a lower average latency and loss percentage, which would make it the preferred WAN station for VoIP traffic. VoIP traffic requires low latency and packet loss to ensure good voice quality and reliability. WAN 1 seems to have higher RAM and processor usage, which could also affect the performance of VoIP traffic.
Here's the summary of the key metrics for WAN 1 and WAN 2 from the image provided:
WAN 1:
Uplink Speed: 10G
Total Usage: 26.969GB Up / 1.748GB Down
Average Throughput: 353MBps Up / 23.42MBps Down
Loss: 2.51%
Average Latency: 24ms
Jitter: 9.5ms
WAN 2:
Uplink Speed: 1G
Total Usage: 930GB Up / 138GB Down
Average Throughput: 12.21MBps Up / 1.82MBps Down
Loss: 0.01%
Average Latency: 11ms
Jitter: 3.9ms
For VoIP traffic, low latency and jitter are particularly important to ensure voice quality. While WAN 1 has higher bandwidth and throughput, it also has higher latency and jitter compared to WAN 2. However, WAN 2 has much lower loss, lower latency, and lower jitter, which are more favorable for VoIP traffic that is sensitive to delays and variation in packet arrival times.
Given this information, WAN 2 would generally be preferred for VoIP traffic due to its lower latency, lower jitter, and significantly lower loss percentage, despite its lower bandwidth compared to WAN 1. The high bandwidth of WAN 1 may be more suitable for other types of traffic that are less sensitive to latency and jitter, such as bulk data transfers.
Device Monitoring:
the device that is experiencing connectivity issues is the APP Server or Router 1, which has a status of Down. This means that the server is not responding to network requests or sending any dat a. You may want to check the physical connection, power supply, and configuration of the APP Server to troubleshoot the problem.
