• Question 242:

  What facilitates a Telnet connection between devices by entering the device name?

  A. SNMP
  B. DNS lookup
  C. syslog
  D. NTP
  B. DNS lookup

• Question 243:

  How are API keys used to enforce rate limiting?

  A. to specify the type of data format the client prefers to receive
  B. to define the network path the API request should take
  C. to encrypt data sent in the API request
  D. to uniquely identify each client application
  D. to uniquely identify each client application

• Question 244:

  When a site-to-site VPN is configured which IPsec mode provides encapsulation and encryption of the entire original IP packet?

  A. IPsec tunnel mode with AH
  B. IPsec transport mode with AH
  C. IPsec tunnel mode with ESP
  D. IPsec transport mode with ESP
  C. IPsec tunnel mode with ESP

  ---

  Authentication Header (AH)

  Encapsulating Security Payload (ESP)

  In Tunnel mode, the entire original IP packet, including its IP header and payload, is encapsulated within a new IP packet. The new IP packet has a different IP header that contains the VPN tunnel endpoints' IP addresses and additional IPsec-related information. In the case of AH tunnel mode, an AH header and a new IP header are added. For ESP tunnel mode, an ESP header, a new IP header, an ESP trailer, and an ESP authentication trailer are added.

• Question 245:

  Refer to the exhibit.

  

  Switch A is newly configured. All VLANs are present in the VLAN database. The IP phone and PC A on Gi0/1 must be configured for the appropriate VLANs to establish connectivity between the PCs.

  Which command set fulfills the requirement?

  A. SwitchA(config-if)#switchport mode access SwitchA(config-if)#switchport access vlan 50 SwitchA(config-if)#switchport voice vlan 51
  B. SwitchA(config-if)#switchport mode access SwitchA(config-if)#switchport access vlan 50 SwitchA(config-if)#switchport voice vlan untagged
  C. SwitchA(config-if)#switchport mode trunk SwitchA(config-if)#switchport trunk allowed vlan add 50,51 SwitchA(config-if)#switchport voice vlan dot1p
  D. SwitchA(config-if)#switchport mode trunk SwitchA(config-if)#switchport trunk allowed vlan 50,51 SwitchA(config-if)#mls qos trust cos
  A. SwitchA(config-if)#switchport mode access SwitchA(config-if)#switchport access vlan 50 SwitchA(config-if)#switchport voice vlan 51

  ---

  First, we have to create the two VLANs:

  SW1(config)#vlan 100
  
  SW1(config-vlan)#name COMPUTER
  
  SW1(config-vlan)#exit

  SW1(config)#vlan 101
  
  SW1(config-vlan)#name VOIP
  
  SW1(config-vlan)#exit

  Now we can configure the interface:

  SW1(config)#interface GigabitEthernet0/1
  
  SW1(config-if)#switchport mode access
  
  SW1(config-if)#switchport access vlan 100
  
  SW1(config-if)#switchport voice vlan 101
  
  SW1(config-if)#exit

  We configure the interface in access mode and use VLAN 100 for the computer. The switchport voice vlan command tells the switch to use VLAN 101 as the voice VLAN.

• Question 246:

  What are two fundamentals of virtualization? (Choose two.)

  A. It allows logical network devices to move traffic between virtual machines and the rest of the physical network.
  B. It allows multiple operating systems and applications to run independently on one physical server.
  C. It allows a physical router to directly connect NICs from each virtual machine into the network.
  D. It requires that some servers, virtual machines, and network gear reside on the Internet.
  E. The environment must be configured with one hypervisor that serves solely as a network manager to monitor SNMP traffic.
  A. It allows logical network devices to move traffic between virtual machines and the rest of the physical network.
  B. It allows multiple operating systems and applications to run independently on one physical server.

• Question 247:

  Which two WAN architecture options help a business scalability and reliability for the network? (Choose two)

  A. asychronous routing
  B. single-homed branches
  C. dual-homed branches
  D. static routing
  E. dynamic routing
  C. dual-homed branches
  E. dynamic routing

  ---

  The two WAN architecture options that help a business scalability and reliability for the network are:

  C. Dual-homed branches: Dual-homing involves connecting each branch office to two or more different WAN links, such as two different service providers, in order to provide redundancy and increase reliability. This architecture option enables the business to maintain network connectivity even if one of the WAN links fails. In addition, it can also provide better performance and scalability by balancing traffic across the multiple links.

  E. Dynamic routing: Dynamic routing protocols enable routers to dynamically exchange information about the network topology and find the best path for data to travel. This allows for faster convergence in case of network changes and improves network scalability by automatically adjusting to changes in the network. Dynamic routing protocols also increase network reliability by providing redundancy and failover mechanisms.

• Question 248:

  Which protocol dynamically resolves an IPv4 address to a MAC address on a local network?

  A. DNS
  B. ICMP
  C. ARP
  D. DHCP
  C. ARP

  ---

  The Address Resolution Protocol (ARP) is used to map an IPv4 address to a corresponding MAC address within the same broadcast domain. When a host needs to send a frame to a known IP address on the local network, it broadcasts an ARP request and receives an ARP reply containing the destination MAC address.

• Question 249:

  Refer to the exhibit.

  

  A network engineer must update the configuration on Switch2 so that it sends LLDP packets every minute and the information sent via LLDP is refreshed every 3 minutes. Which configuration must the engineer apply?

  A. Switch2(config)#lldp timer 60 Switch2(config)#lldp holdtime 180
  B. Switch2(config)#lldp timer 60 Switch2(config)#lldp tlv-select 180
  C. Switch2(config)#lldp timer 1 Switch2(config)#lldp holdtime 3
  D. Switch2(config)#lldp timer 1 Switch2(config)#lldp tlv-select 3
  A. Switch2(config)#lldp timer 60 Switch2(config)#lldp holdtime 180

• Question 250:

  Refer to the exhibit.

  

  Users will be using a preconfigured secret key and SSID and must have a secured key hashing algorithm configured.

  The AAA server must not be used for the user authentication method.

  Which action completes the task?

  A. Enable AutoConfig iPSK.
  B. SetCCMP128(AES).
  C. Configure PSK Format HEX with key string.
  D. Configure PSK-SHA2.
  D. Configure PSK-SHA2.
