H3C GB0-510 (H3CNE-Security) Sample Questions:

01. Two branch gateways protect traffic between the subnets behind them with IPsec.
Which statement distinguishes tunnel mode from transport mode in this deployment?
a) Tunnel mode protects traffic with ESP, while transport mode is the mode used when AH provides the protection
b) Transport mode wraps the entire original packet in a new packet addressed between the gateways, while tunnel mode protects only the payload of the original packet
c) Tunnel mode wraps the entire original packet in a new packet addressed between the gateways, which is what lets them protect traffic on behalf of the hosts behind them
d) Tunnel mode authenticates the peers with a pre-shared key, while transport mode requires each peer to hold a certificate
 
02. A company gives home-based staff remote access with an L2TP tunnel, so that their laptops receive an address from the office range. A reviewer objects that the design does not meet the confidentiality requirement.
What is the basis of that objection?
a) L2TP derives its encryption from the user's password, so the requirement is met by moving authentication to a stronger source such as a RADIUS server
b) L2TP carries the remote session but provides no encryption of its own, which is why it is paired with IPsec where the traffic has to be kept confidential
c) L2TP encrypts the tunnel setup exchange but not the data that follows, so a second tunnel has to be nested inside the first to protect the data
d) L2TP protects the payload but leaves the original addressing visible, so GRE is added to conceal which hosts are communicating
 
03. A site-to-site IPsec tunnel runs over a broadband link that occasionally fails without either gateway losing its own interface. After such a failure the branch gateway keeps its security associations and traffic is discarded until an administrator clears them by hand.
Which mechanism removes the manual step?
a) Aggressive mode negotiation, so fewer exchanges are needed and the tunnel re-establishes as soon as the link returns
b) NAT traversal, so the security associations survive a device between the peers that rewrites their addresses while the link is unstable
c) Dead peer detection, so each gateway probes the other over the established association and tears it down when the peer stops responding
d) Perfect forward secrecy, so a fresh key exchange is performed for each new security association and stale key material cannot be reused
 
04. Every member of staff at a branch reaches the internet through one shared public address. An external provider reports abusive traffic from that address during a particular hour and asks the branch to identify the machine involved.
Which gateway capability supports that request?
a) NAT session logging, which records each translation with the original private address and port alongside the public address and port it was given
b) Interface traffic statistics for the internet-facing interface, which record how much traffic the branch sent and received during that hour
c) The hit counters on the outbound security rules, which record how many sessions matched each rule during that hour
d) The address object referenced by the translation rule, which lists the private addresses that are eligible to be translated
 
05. A designer is documenting the consequences of putting many-to-one source translation in front of a branch network, where all internal hosts share one public address.
Which two of the following follow from that design?
(Choose two.)
a) Hosts on the public network cannot start a session to an internal host unless a mapping publishes that host explicitly
b) Records kept outside the branch show the shared public address rather than the individual host that generated the traffic
c) Outbound sessions no longer need a security rule, because traffic the gateway translates has been admitted by the translation itself
d) Each internal host still needs a public address of its own, because the translation keeps a one-to-one rather than a many-to-one relationship between private and public addresses
 
06. An engineer opens a management session to the firewall's own address in order to check its configuration. Traffic that terminates on the device is evaluated differently from traffic the device forwards between networks.
Which security zone represents the firewall itself when such a session is matched by a security rule?
a) Untrust
b) Local
c) Trust
d) DMZ
 
07. From a Trust-zone workstation an administrator browses the Internet without trouble through a rule permitting Trust to Untrust. An HTTPS session from that same workstation to the firewall's own inside interface, for web management, times out.
What best explains the difference?
a) The firewall builds no session for traffic addressed to itself, so the management flow cannot be tracked or forwarded
b) Web management is reachable only from the Untrust zone, because an inside interface carries transit traffic only
c) The Trust-to-Untrust rule shadows the management service, because it is matched first for every packet that interface receives
d) Traffic addressed to the device itself is evaluated against the policy for sessions that terminate on the gateway rather than against the transit rule
 
08. A 120-person insurance broker is writing its first outbound access baseline. Every department currently has unrestricted access, and one proposal argues that tightening it would generate too many support calls to be worth the trouble.
Which argument applies the principle of least privilege to this decision?
a) Grant each department only the access its work needs, so a compromised endpoint cannot reach services that department never used
b) Grant access in proportion to the seniority of each department's staff, since senior staff are already trusted with more of the business
c) Grant access broadly now and withdraw it from any department that suffers an incident, so the business is not slowed while it is still safe
d) Grant every department identical access, because inconsistent permissions are the main source of support calls
 
09. A remote-access design encrypts bulk traffic with a symmetric key, while an asymmetric key pair is used only while the session is being set up.
Why is the work split this way?
a) Symmetric keys are longer than asymmetric keys, so they are always the stronger of the two choices
b) Asymmetric algorithms cannot protect confidentiality at all, so the key pair is only ever used to sign
c) Symmetric encryption is far cheaper to compute over large volumes, while the key pair solves the problem of agreeing that symmetric key across an untrusted path
d) Only symmetric algorithms can detect modification of data, so bulk traffic must use them for integrity
 
10. A vendor publishes a firmware image together with a digital signature produced with the vendor's private key.
Which two assurances does verifying that signature give the engineer who downloads the image?
(Choose two.)
a) The image contains no vulnerabilities, because the vendor tested it before signing
b) The image has not been modified since it was signed
c) The image cannot be read by anyone who intercepts the download
d) The image was signed by the holder of the vendor's private key
