NEW QUESTION # 39
What is the name of the root element of the LDAP tree holding the configuration of an OpenLDAP server that is using directory based configuration?
(Specify ONLY the element's name without any additional information.)
Answer:
Explanation:
cn=config
Explanation:
The root element of the LDAP tree holding the configuration of an OpenLDAP server that is using directory based configuration is called cn=config. This is a special entry that is not part of the regular data DITs, but rather a separate DIT that can be used to configure the OpenLDAP server online. The cn=config entry contains various subentries that define the global and database-specific settings for the server. The cn=config entry can be accessed and modified using standard LDAP tools and methods, such as ldapsearch and ldapmodify12.

NEW QUESTION # 43
For what purpose is TCP/IP stack fingerprinting used by nmap?
- A. It is used to masquerade the responses of remote servers.
- B. It is used to determine the remote operating system.
- C. It is used to uniquely identify servers on the network for forensics.
- D. It is used to filter out responses from specific servers.
- E. It is used to identify duplicate responses from the same remote server.
Answer: B
Explanation:
Explanation
TCP/IP stack fingerprinting is a technique that allows nmap to remotely detect the characteristics of a TCP/IP stack implementation on a target host. By sending a series of probes (such as TCP and UDP packets) and analyzing the responses, nmap can infer the operating system (OS) of the target host based on a database of known OS fingerprints. Each OS has a unique way of setting certain parameters and flags in the TCP/IP headers, such as the initial packet size, the initial TTL, the window size, the max segment size, the window scaling value, and the "don't fragment", "sackOK", and "nop" flags. These values can be combined to form a signature or a fingerprint for the target host, which can then be compared to the nmap-os-db database that contains more than 2,600 OS fingerprints. If there is a match, nmap will print out the OS details, such as the name, the version, and the vendor. If there is no match, nmap will print out a message asking the user to submit the fingerprint to the nmap project for further analysis.
TCP/IP stack fingerprinting is useful for several purposes, such as network mapping, security auditing, vulnerability scanning, and penetration testing. By knowing the OS of the target host, nmap can tailor its scanning techniques and exploit the weaknesses of the specific OS. TCP/IP stack fingerprinting can also help identify rogue or unauthorized devices on a network, or detect OS spoofing attempts by the target host.

NEW QUESTION # 44
Which option in named.conf specifies which host are permitted to ask for domain name information from the server?
- A. allow-query
- B. accept-query
- C. permit-query
- D. allowed-hosts
- E. query-group
Answer: A
Explanation:
Explanation
The option in named.conf that specifies which hosts are permitted to ask for domain name information from the server is allow-query. The allow-query option is used to define an access control list (ACL) that matches the source IP address of the DNS query. The ACL can be a list of IP addresses, networks, keywords, or predefined ACL names. The default value of allow-query is any, which means that any host can query the server. However, this can pose a security risk, as the server may be exposed to unwanted or malicious queries.
Therefore, it is recommended to restrict the allow-query option to only the hosts that need to access the server, such as the local network or trusted clients. For example, the following option allows only the hosts in the
192.168.1.0/24 network and the localhost to query the server:
allow-query { 192.168.1.0/24; localhost; };
The other options are not valid in named.conf. allowed-hosts, accept-query, permit-query, and query-group are not recognized keywords by BIND.

NEW QUESTION # 47
Which of the following is correct about this excerpt from an LDIF file?
- A. DC is the delegation container.
- B. o is the operator name.
- C. dn is the relative distinguished name.
- D. cn is the common name.
- E. dn is the domain name.
Answer: D
Explanation:
Explanation
The excerpt from an LDIF file shows the attributes of an LDAP object that represents a person named John Smith. The dn attribute is the distinguished name, which uniquely identifies the object in the LDAP directory.
The dn is composed of one or more relative distinguished names (RDNs), which are attribute-value pairs separated by commas. In this case, the dn has three RDNs: cn=John Smith, ou=People, and dc=example. The cn attribute is the common name, which is a human-readable name for the object. The ou attribute is the organizational unit, which is a container for grouping objects. The dc attribute is the domain component, which is used to form the domain name of the directory. The o attribute is the organization name, which is an optional attribute that can be used to specify the name of the organization that the object belongs to. The objectClass attribute is a multi-valued attribute that specifies the object classes that the object belongs to. Each object class has a schema that defines the mandatory and optional attributes that the object can have. In this case, the object belongs to two object classes: inetOrgPerson and organizationalPerson. The inetOrgPerson object class is a standard object class for representing people in an Internet directory. The organizationalPerson object class is a standard object class for representing people who belong to an organization. The sn attribute is the surname, which is a mandatory attribute for the inetOrgPerson and organizationalPerson object classes. The mail attribute is the email address, which is an optional attribute for the inetOrgPerson and organizationalPerson object classes. References:

NEW QUESTION # 49
A zone file contains the following lines:
and is included in the BIND configuration using this configuration stanza:
Which problem is contained in this configuration?
- A. The $ORIGIN declaration cannot be used in zone files that are included for a specific zone name in the BIND configuration.
- B. The zone statement is the BIND configuration must contain the cross-zone-data yes; statement.
- C. The zone cannon contain records for a name which is outside the zone's hierarchy.
- D. An A record cannot contain an IPv4 address because its value is supposed to be a reverse DNS name.
- E. Names of records in a zone file cannot be fully qualified domain names.
Answer: C
Explanation:
Explanation
A zone file is a text file that defines a portion of the DNS namespace, called a zone. A zone file contains resource records that map domain names to IP addresses or other information. A zone file must follow the rules of the DNS hierarchy, which means that it can only contain records for names that are within the zone's domain. For example, a zone file for example.com can only contain records for names that end with example.com, such as www.example.com or mail.example.com. It cannot contain records for names that are outside the zone's domain, such as google.com or example.net. This is because the DNS server that hosts the zone file is only authoritative for the zone's domain, and not for any other domains. If a zone file contains records for names that are outside the zone's hierarchy, it will cause errors and inconsistencies in the DNS resolution process.
