  2. Strobe
  3. FTP bounce
  4. Vanilla

Which of the following is a firewall that keeps track of the state of network connections traveling across it?

  1. Stateful firewall
  2. Stateless packet filter firewall
  3. Circuit-level proxy firewall
  4. Application gateway firewall

Answer(s): A

Explanation:

A stateful firewall is a firewall that keeps track of the state of network connections (such as TCP streams, UDP communication) traveling across it. The firewall is programmed to distinguish legitimate packets for different types of connections. Only packets matching a known connection state will be allowed by the firewall; others will be rejected. Answer option B is incorrect. A stateless packet filter firewall allows direct connections from the external network to hosts on the internal network and is included with router configuration software or with Open Source operating systems.
Answer option C is incorrect. It applies security mechanisms when a TCP or UDP connection is established. Answer option D is incorrect. An application gateway firewall applies security mechanisms to specific applications, such as FTP and Telnet servers.



FILL BLANK
Fill in the blank with the appropriate term. ________________encryption is a type of encryption that uses two keys, i.e., a public key and a private key pair for data encryption. It is also known as public key encryption.

  1. Asymmetric

Answer(s): A

Explanation:

Asymmetric encryption is a type of encryption that uses two keys, i.e., a public key and a private key pair for data encryption. The public key is available to everyone, while the private or secret key is available only to the recipient of the message. For example, when a user sends a message or data to another user, the sender uses the public key to encrypt the data. The receiver uses his private key to decrypt the data.



FILL BLANK
Fill in the blank with the appropriate term. ________________is a protocol used to synchronize the timekeeping among the number of distributed time servers and clients.

  1. NTP

Answer(s): A

Explanation:

Network Time Protocol (NTP) is used to synchronize the timekeeping among the number of distributed time servers and clients. It is used for the time management in a large and diverse network that contains many interfaces. In this protocol, servers define the time, and clients have to be synchronized with the defined time. These clients can choose the most reliable source of time defined from the several NTP servers for their information transmission.



FILL BLANK
Fill in the blank with the appropriate term. The _____________is a communication protocol that communicates information between the network routers and the multicast end stations.

  1. IGMP

Answer(s): A

Explanation:

The Internet Group Management Protocol (IGMP) is a communication protocol that communicates information between the network routers and the multicast end stations. It allows the receivers to request a multicast data stream from a specific group address. However, multicast traffic is sent to a single MAC address but is processed by multiple hosts. The IGMP allows an end station to connect to a multicast group and leave it, while being connected to the group address. It can be effectively used for gaming and showing online videos.
Although it does not actually act as a transport protocol, it operates above the network layer. It is analogous to ICMP for unicast connections. It is susceptible to some attacks, so firewalls commonly allow the user to disable it if not needed.

question 35 is incorrect, the correct answer is c, it even states so: explanation: when a vm is infected with ransomware, you should not restore the vm to the infected vm. this is because the ransomware will still be present on the vm, and it will encrypt the files again. you should also not restore the vm to any vm within the companys subscription. this is because the ransomware could spread to other vms in the subscription. the best way to restore a vm that is infected with ransomware is to restore it to a new azure vm. this will ensure that the ransomware is not present on the new vm.
