Zusammenfassung der Ressource

Frage 1

Frage
Uses UDP port 500 (and UDP port 4500 when crossing NAT) Negotiates a tunnel’s private keys, authentication, and encryption One lPsec SA is used per traffic direction. Phases: Phase1 Phase2
Antworten
  • IKE
  • ESP
  • AH

Frage 2

Frage
Phase 1 negotiation modes
Antworten
  • main mode aggresive mode
  • main mode quick mode

Frage 3

Frage
Phase 2 negotiation mode
Antworten
  • aggresive mode
  • quick mode

Frage 4

Frage
takes place when each endpoint of the tunnel—the initiator and the responder—connects and begins to set up the VPN.
Antworten
  • Phase 1
  • Phase 2

Frage 5

Frage
[blank_start]2.[blank_end] Negotiate one bidirectional SA (called IKE SA) *ln IKE v1, two possible ways: -Main mode: six packets exchanged -Aggressive mode: three packets exchanged *Not the same as final SAs later *Encrypted tunnel for Diffie-Hellman (DH) [blank_start]1 .[blank_end] Authenticate peers *Pre—shared key or digital signature *Extended authentication (XAuth) [blank_start]3.[blank_end] DH exchange for secret keys
Antworten
  • 2.
  • 1 .
  • 3.

Frage 6

Frage
Key agreement method: Independently calculate a private key using only public keys Each FortiGate uses a shared secret key plus a nonce to calculate keys for the following: Symmetric encryption algorithms (such as 3DES, AES) Symmetric authentication (HMACs)
Antworten
  • Diffie-Hellman
  • IKE
  • ESP

Frage 7

Frage
ESP can´t support NAT because it has no port numbers.
Antworten
  • True
  • False

Frage 8

Frage
Negotiates two unidirectional SAs for ESP (called lPsec SAS) Protected by phase IKE SA When SAs are about to expire, it renegotiates Optionally, if Perfect Forward Secrecy is set to Enabled, FortiGate uses Diffie-Hellman to generate new keys each time phase 2 expires. Each phase 1 can have multiple phase 2s. High security subnets can have stronger ESP.
Antworten
  • Phase 2
  • Phase 1

Frage 9

Frage
Also, if you set ____________ to Enable, each time phase 2 expires, FortiGate will use Diffie-Hellman to recalculate new secret keys. In this way, new keys are not derived from older keys, making it much harder for an attacker to crack the tunnel.
Antworten
  • Perfect Forward Secrecy
  • NAT-Transversal
  • Split tunneling

Frage 10

Frage
If multiple phase 2 exist, FortiGate directs traffic to the correct phase 2. Allows granular security settings for each LAN. If traffic does not match an lPsec SA selector, it is dropped. ln point-to-pointVPNs, selectors must match. - The source on one FortiGate is the destination setting on the other. Select which SA to apply using: Destination and source IP subnet(s) Protocol number Source port and destination port
Antworten
  • Quick mode selectors
  • Phase 2
  • Phase 1
  • Agressive mode

Frage 11

Frage
During phase 2, you must configure a pair of settings called quick mode selectors. They identify and direct traffic to the appropriate phase 2. In other words, they allow granular SAs.
Antworten
  • True
  • False

Frage 12

Frage
In aggressive mode, how many packets are exchanged to establish phase 1 of the lPsec tunnel?
Antworten
  • A. Six
  • B. Three

Frage 13

Frage
Which statement about quick mode selectors is true?
Antworten
  • A. Only phase 2 has quick mode selectors.
  • B. Only phase 1 has quick mode selectors.

Frage 14

Frage
Settings need in Dialup VPN between two fortigates
Antworten
  • A phase 1 At least one phase 2 Firewall policies Static routes or a dynamic routing protocol
  • A phase 1 At least one phase 2 Firewall policies Static routes or a dynamic routing protocol IPsec interface

Frage 15

Frage
Dialup IPsec is also known as
Antworten
  • A. point-to-point
  • B. point-to—multipoint

Frage 16

Frage
IKE mode configuration automatically configures network settings?
Antworten
  • A. client
  • B. server
