NEW QUESTION # 519
A network administrator is conducting an assessment and found network devices that do not meet standards. Which of the following configurations is considered a set of rules that devices should adhere to?
Answer: C
NEW QUESTION # 520
Which of the following devices can operate in multiple layers of the OSI model?
Answer: A
Explanation:
* Understanding Switches:
* Layer 2 (Data Link Layer): Traditional switches operate primarily at Layer 2, where they use MAC addresses to forward frames within a local network.
* Layer 3 (Network Layer): Layer 3 switches, also known as multilayer switches, can perform routing functions using IP addresses to forward packets between different networks.
* Capabilities of Multilayer Switches:
* VLANs and Inter-VLAN Routing: Multilayer switches can handle VLAN (Virtual Local Area Network) configurations and perform inter-VLAN routing, enabling communication between different VLANs.
* Routing Protocols: They can run routing protocols like OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol) to manage traffic between networks.
* Comparison with Other Devices:
* Hub: Operates only at Layer 1 (Physical Layer) and simply repeats incoming signals to all ports.
* Transceiver: Also operates at Layer 1, converting electrical signals to optical signals and vice versa.
* Modem: Primarily operates at Layer 1 and Layer 2, modulating and demodulating signals for transmission over different types of media.
* Practical Application:
* Multilayer switches are commonly used in enterprise networks to optimize performance and manage complex routing and switching requirements within a single device.
NEW QUESTION # 521
A virtual machine has the following configuration:
*IPv4 address: 169.254.10.10
*Subnet mask: 255.255.0.0
The virtual machine can reach colocated systems but cannot reach external addresses on the Internet. Which of the following Is most likely the root cause?
Answer: B
Explanation:
Understanding the 169.254.x.x Address:
An IPv4 address in the range of 169.254.x.x is an Automatic Private IP Addressing (APIPA) address, assigned when a DHCP server is unavailable.
DHCP Server Offline:
APIPA Assignment: When a device cannot obtain an IP address from a DHCP server, it assigns itself an APIPA address to enable local network communication. This allows communication with other devices on the same local subnet but not with external networks.
Resolution: Ensure the DHCP server is operational. Check for connectivity issues between the virtual machine and the DHCP server, and verify the DHCP server settings.
Comparison with Other Options:
The subnet mask is incorrect: The subnet mask 255.255.0.0 is appropriate for the 169.254.x.x range and does not prevent external access by itself.
The IP address is an RFC1918 private address: RFC1918 addresses are private IP ranges (10.x.x.x, 172.16.x.x-
172.31.x.x, 192.168.x.x) but 169.254.x.x is not one of them.
The DNS server is unreachable: While this could affect name resolution, it would not prevent the assignment of a non-APIPA address or local network communication.
Troubleshooting Steps:
Verify the DHCP server's status and connectivity.
Restart the DHCP service if necessary.
Renew the IP lease on the virtual machine using commands such as ipconfig /renew (Windows) or dhclient (Linux).

NEW QUESTION # 522
Which of the following high-availability strategies ensures that multiple systems or sites run simultaneously to distribute load and provide immediate failover with minimal downtime?
Answer: A
Explanation:
In financial institutions such as stock exchanges, downtime or latency can have severe consequences. Active- active high availability ensures multiple sites/systems are running simultaneously, distributing the load and providing immediate failover with minimal or no interruption. This is the best approach for environments that require continuous uptime and resiliency.
* A. Warm site: Useful for disaster recovery, but not immediate; systems must be partially configured and brought online.
* C. Full mesh: Refers to topology interconnections, not DR/HA design.
* D. In-band: Relates to management methods, not HA/DR strategies.
References (CompTIA Network+ N10-009):
* Domain: Network Infrastructure - High availability, redundancy strategies, active-active vs. active- passive design.
NEW QUESTION # 523
After a recent security awareness phishing campaign, the cybersecurity team discovers that additional security measures need to be set up when users access potentially malicious websites. Which of the following security measures will best address this concern?
Answer: B
Explanation:
DNS filtering blocks access to known malicious websites by comparing domain requests against a list of allowed or blocked URLs. It is an effective defense against phishing and other web-based attacks.
From Andrew Ramdayal's guide:
"URL filtering restricts access to specific websites or web content by comparing URLs against a predefined list of allowed or blocked sites...commonly used to prevent users from accessing malicious sites."
