  Explanation/Reference:

• Question 112:

  A company is being acquired by a large corporation. As part of the acquisition process, the company's address should now redirect clients to the corporate organization page. Which of the following DNS records needs to be created?

  A. SOA
  B. NS
  C. CNAME
  D. TXT
  C. CNAME

  ---

  Explanation/Reference:

  CNAME (Canonical Name) is a type of DNS record that maps an alias name to another name, which can be either another alias or the canonical name of a host or domain. A CNAME record can be used to redirect clients from one domain name to another domain name, such as from the company's address to the corporate organization page. SOA (Start of Authority) is a type of DNS record that specifies authoritative information about a DNS zone, such as the primary name server, contact email address, serial number, refresh interval, etc., which does not redirect clients to another domain name. NS (Name Server) is a type of DNS record that specifies which name server is authoritative for a domain or subdomain, which does not redirect clients to another domain name. TXT (Text) is a type of DNS record that provides arbitrary text information about a domain or subdomain, such as SPF (Sender Policy Framework) records or DKIM (DomainKeys Identified Mail) records, which does not redirect clients to another domain name.

• Question 113:

  Which of the following devices and encapsulations are found at me data link layer? (Select TWO)

  A. Session
  B. Frame
  C. Firewall
  D. Switch
  E. Packet
  F. Router
  B. Frame
  D. Switch

  ---

  Explanation/Reference:

  The data link layer is responsible for defining the format of data on the network and providing physical transmission of data. Devices that operate at this layer include switches and network interface cards (NICs). Encapsulations that are used at this layer include frames, which are units of data that contain a header, payload, and trailer. Frames are used to identify the source and destination of data on the network and to perform error detection.

• Question 114:

  A network administrator is trying to add network redundancy for the server farm. Which of the following can the network administrator configure to BEST provide this capability?

  A. VRRP
  B. DNS
  C. UPS
  D. RPO
  A. VRRP

  ---

  Explanation/Reference:

  VRRP is an open standard protocol, which is used to provide redundancy in a network. It is a network layer protocol (protocol number-112). The number of routers (group members) in a group acts as a virtual logical router which will be the default gateway of all the local hosts. If one router goes down, one of the other group members can take place for the responsibilities for forwarding the traffic.

• Question 115:

  Which of the following routing protocols is generally used by major ISPs for handling large-scale internet traffic?

  A. RIP
  B. EIGRP
  C. OSPF
  D. BGP
  D. BGP

  ---

  Explanation/Reference:

  BGP (Border Gateway Protocol) is generally used by major ISPs for handling large-scale internet traffic. BGP is a routing protocol that is used to exchange routing and reachability information between networks. It is particularly well-suited for handling internet traffic, as it can scale to handle a large number of routes and is capable of routing traffic across multiple Autonomous Systems (ASes). BGP is the main routing protocol used by major ISPs to exchange routing information with each other and with other networks on the internet. Other routing protocols such as RIP, EIGRP, and OSPF may be used in smaller networks or for specific purposes, but are not typically used by major ISPs for handling large-scale internet traffic

• Question 116:

  During a client audit, a network analyst is tasked with recommending changes to upgrade the client network and readiness. Afield technician has submitted the following report:

  

  Based on this report, which of the following metrics or sensors would be the BEST recommendation to the client?

  A. Electrical
  B. Humidity
  C. Flooding
  D. Temperature
  D. Temperature

  ---

  Explanation/Reference:

  Based on the report, the BEST recommendation to the client would be to monitor temperature.

  The report mentions poor ventilation in the space where the IT closet and storage room are located. This suggests that there may be a risk of overheating, which could have negative impacts on the performance and health of the network equipment. Monitoring temperature can help detect and prevent overheating, which can improve the reliability and lifespan of the equipment.

  While humidity and flooding can also be important to monitor in certain environments, they are not specifically mentioned in the report and may not be as pressing of an issue in this case. Electrical monitoring may be useful for detecting power surges or other electrical issues, but it is not directly related to the issues mentioned in the report.

• Question 117:

  A rogue AP was found plugged in and providing Internet access to employees in the break room. Which of the following would be BEST to use to stop this from happening without physically removing the WAP?

  A. Password complexity
  B. Port security
  C. Wireless client isolation
  D. Secure SNMP
  B. Port security

  ---

  Explanation/Reference:

  Port security, would be the best option to use to stop the rogue AP in this scenario. Port security is a feature that can be used to limit the number of devices that can be connected to a switchport. By configuring port security on the switchport to which the rogue AP is connected, the network administrator can ensure that only authorized devices are able to connect to the network and receive an IP address. This would prevent unauthorized devices, such as the rogue AP, from providing Internet access to employees in the break room.

• Question 118:

  A network administrator is planning a WLAN for a soccer stadium and was advised to use MU-MIMO to improve connection performance in high-density areas. The project requires compatibility with clients connecting using 2.4GHz or 5GHz frequencies.

  Which of the following would be the BEST wireless standard for this project?

  A. 80211ac
  B. 802.11ax
  C. 802.11g
  D. 80211n
  B. 802.11ax

  ---

  Explanation/Reference:

  802.11a - 5GHZ 802.11b - 2.4GHZ 802.11g - 2.4GHZ 802.11n - 2.4/5GHZ MIMO 802.11ac - 5GHZ MU-MIMO 802.11ax - 2.4/5/6GHZ MU-MIMO

• Question 119:

  All packets arriving at an interface need to be fully analyzed. Which of me following features should be used to enable monitoring of the packets?

  A. LACP
  B. Flow control
  C. Port mirroring
  D. NetFlow exporter
  C. Port mirroring

  ---

  Explanation/Reference:

  Port mirroring is a feature that can be used to enable monitoring of all packets arriving at an interface. This feature is used to direct a copy of all traffic passing through the switch to a monitoring device, such as a network analyzer. This allows the switch to be monitored with the network analyzer in order to identify any malicious or suspicious activity. Additionally, port mirroring can be used to troubleshoot network issues, such as latency or poor performance.

• Question 120:

  Which of the following DNS records works as an alias to another record?

  A. AAAA
  B. CNAME
  C. MX
  D. SOA
  B. CNAME

  ---

  Explanation/Reference:

  AAAA record is used to find the IP address of a computer connected to the internet from a name.

  CNAME record is a type of DNS record that maps an alias name to a true or canonical domain name.MX record specifies the mail server responsible for accepting email messages on behalf of a domain name.

  SOA record is a type of resource record in the DNS containing administrative information about the zone.
