🧐 Question
Medium Mac address and IP on router hop Routers Switches	Solve
Refer to the following exhibit: Host A is sending a packet to Host B. 1. What is the source and destination MAC address at point PA? 2. What is the source and destination IP address at point PB? // Option A PA: source MAC - Mac-A PA: destination MAC - Mac-B PB: source IP - 192.168.1.1 PB: destination IP - 192.168.3.1 // Option B PA: source MAC - Mac-A PA: destination MAC - Mac-RA PB: source IP - 192.168.3.3 PB: destination IP - 192.168.3.1 // Option C PA: source MAC - Mac-A PA: destination MAC - Mac-B PB: source IP - 192.168.3.3 PB: destination IP - 192.168.3.1 // Option D PA: source MAC - Mac-A PA: destination MAC - Mac-RA PB: source IP - 192.168.1.1 PB: destination IP - 192.168.3.1
Easy MX Record, DMARC and Email Authentication DNS MX Records DMARC SPF DKIM	Solve
You work as a network administrator for a company, "example.com", that recently started experiencing issues with email spoofing. To mitigate the problem, you decide to implement DMARC (Domain-based Message Authentication, Reporting & Conformance) in addition to existing SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records. Your current DNS records for example.com include the following: - MX 10 mail.example.com (IP address 203.0.113.10) - TXT "v=spf1 ip4:203.0.113.10 -all" - TXT "v=DKIM1; k=rsa; p=public-key-here" You add the following DMARC record: - TXT "_dmarc.example.com" "v=DMARC1; p=quarantine; pct=100; rua=mailto:report@example.com" After implementing the DMARC record, an external mail server sends an email to your domain. The email passes the SPF and DKIM checks but fails the DMARC check. What will likely happen to the email? A: The email will be accepted and delivered to the recipient's inbox. B: The email will be rejected and returned to the sender as undeliverable. C: The email might be delivered to the recipient's spam or junk folder. D: The email will be accepted, but a report will be sent to the sender. E: The email will be silently discarded, and the sender will not be notified.
Medium Remote network resources Gateway Routing protocols	Solve
Review the following exhibit: Angelina noticed that the computers on 192.168.10.0/24 network can ping their default gateway. But they found that these computers cannot connect to any remote network resources. Which of the following is the most likely reason for this?
Medium SSL Certificate Expiry SSL/TLS Network Security	Solve
You are a network administrator for an e-commerce company. The company's online store allows customers to browse products and make purchases securely over the internet. The online store uses SSL/TLS for secure communication. You receive reports that some customers are seeing a security warning in their web browsers when trying to access the online store. Upon investigation, you discover the following information: - The SSL certificate used by the online store's web server is valid for one year and is due to expire in two days. - The web server is configured to automatically redirect HTTP traffic to HTTPS. - The SSL certificate was issued by a trusted certificate authority (CA), and all major web browsers have the CA's root certificate in their trusted certificate stores. - The SSL certificate includes the correct domain name for the online store. Given the above information, which of the following steps should be taken to resolve the issue and prevent customers from seeing the security warning? A: Extend the validity of the current SSL certificate by one year. B: Obtain a new SSL certificate from the same CA and install it on the web server before the current certificate expires. C: Remove the automatic redirect from HTTP to HTTPS on the web server. D: Ask customers to ignore the security warning and proceed to the online store. E: Replace the SSL certificate with a self-signed certificate.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Teste de engenheiro de rede in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Science behind Adaface tests

Reason #6

1 click candidate invites

What topics are covered in the Teste online de engenheiro de rede?

rede sem fio Tecnologias de comunicação, como Wi-Fi, Bluetooth ou redes celulares. Os engenheiros de rede com experiência em redes sem fio podem projetar e implementar redes sem fio confiáveis e seguras, além de solucionar problemas de conectividade ou problemas de desempenho nesses ambientes. </p> <h4> design de rede
O design da rede implica a criação de um plano ou plano para uma infraestrutura de rede que atenda aos requisitos de negócios específicos. Os engenheiros de rede com proficiência no design da rede podem otimizar o layout de dispositivos, determinar esquemas de endereçamento IP, selecionar topologias de rede apropriadas e garantir escalabilidade e utilização de recursos eficientes.
Gerenciamento de rede
Gerenciamento de rede Envolve o monitoramento, a configuração e o controle de dispositivos e recursos de rede para garantir sua operação suave. Essa habilidade abrange o conhecimento dos protocolos de gerenciamento de rede, como SNMP, bem como ferramentas e técnicas para monitoramento de desempenho, detecção de falhas e gerenciamento de configuração.
tcp/ip
tcp/ip (Protocolo de controle de transmissão/protocolo da Internet) é o conjunto de protocolo padrão usado para comunicação na Internet. A compreensão do TCP/IP é fundamental para os engenheiros de rede, pois lhes permite efetivamente solucionar problemas e gerenciar problemas de conectividade de rede, garantir a interoperabilidade de diferentes dispositivos e redes e implementar medidas de segurança para proteger os dados transmitidos pela rede.
LAN/WAN
LAN (rede local de áreas) e WAN (Wide Area Reth) referem -se a diferentes tipos de redes que conectam dispositivos em diferentes áreas geográficas. A avaliação do conhecimento LAN/WAN ajuda os recrutadores a avaliar a capacidade de um candidato de projetar, implementar e gerenciar arquiteturas de rede, incluindo redes locais em um edifício ou campus (LAN) e redes que abrangem vários locais e conectadas através de links públicos ou privados (WAN). </ P> <H4> Otimização de desempenho da rede </h4> <p> Otimização de desempenho da rede envolve analisar e ajustar a infraestrutura de rede para maximizar sua velocidade, eficiência e confiabilidade. Profissionais com experiência nessa habilidade podem empregar várias técnicas e ferramentas, como otimização de largura de banda, análise de tráfego ou configuração de qualidade de serviço (QoS), para otimizar o desempenho da rede e oferecer uma melhor experiência do usuário.

Como interpreto as pontuações dos testes?

O principal a ter em mente é que uma avaliação é uma ferramenta de eliminação, não uma ferramenta de seleção. Uma avaliação de habilidades é otimizada para ajudá -lo a eliminar os candidatos que não são tecnicamente qualificados para o papel, não é otimizado para ajudá -lo a encontrar o melhor candidato para o papel. Portanto, a maneira ideal de usar uma avaliação é decidir uma pontuação limite (normalmente 55%, ajudamos você a comparar) e convidar todos os candidatos que pontuam acima do limiar para as próximas rodadas da entrevista.

Para que nível de experiência posso usar este teste?

Cada avaliação do Adaface é personalizada para a descrição do seu trabalho/ persona do candidato ideal (nossos especialistas no assunto escolherão as perguntas certas para sua avaliação de nossa biblioteca de mais de 10000 perguntas). Esta avaliação pode ser personalizada para qualquer nível de experiência.

Todo candidato recebe as mesmas perguntas?

Sim, facilita muito a comparação de candidatos. As opções para perguntas do MCQ e a ordem das perguntas são randomizadas. Recursos anti-traking/proctoring no local. Em nosso plano corporativo, também temos a opção de criar várias versões da mesma avaliação com questões de níveis de dificuldade semelhantes.
